Overclocking ddr4 DEFAULT

There is no doubt that:

RAM overclocking is vital for the PC Enthusiast and gamers. You can’t utilize your expensive RAM properly without overclocking it.

But you might be wondering:

Does overclocking memory modules bring any big change in a PC’s performance?

The simplest answer is:

Yes, it definitely does and i will explain it later.

You might be very confused about overclocking.

But the fact is:

After reading this epic DDR4 RAM overclocking guide, it will take you only 5 minutes to do the job!


In this tutorial I will show you the simplest way on how to overclock your RAM DDR4 to a suitable speed.

And I will also tell you if RAM overclocking is worth it or not.

I have answers to all your questions. So, sit back relax and let’s get started.

At the end of this post, I will tell you the pros. and cons. of RAM Overclocking.

Why Overclock RAM?

RAM are now sold at different speeds/frequencies. But you don’t get that speed at default configurations.

If you check the RAM speed you will see that the RAM is locked at a certain frequency.it is not fully utilizing that speed. To increase that speed you need to overclock the ram.


There are many advantages of RAM overclocking .Some of the advantages are more FPS(Frames Per Second) in games, more stable while multitasking etc.

Whatever you do make sure that your PSU is sufficient for overclocking.

If you don’t know anything about your computer’s Power Supply then check our post on what power supply do I have.

Also check out how to speed up your monitor’s refresh rate.

Which is Better? Faster RAM or More RAM?

This is the most common problem that a RAM buyer faces before buying a RAM. But the answer to this question actually depends on many factors.

In short:

If you have a good budget then buy ram with more speed. Or else, buy a less rated speed ram with of the memory I have discussed right above.

If you are a normal user 8 GB RAM is sufficient for you right now. On the other hand, if you do random heavy tasks on you computer for example: You open a lot of Tabs in your internet browser, or you play hardcore games on your PC etc. then 16 GB is good for you.

Again if you stream games online or you do editings and other heavy tasks on your computer then you can even keep more RAM.

So, if you can buy RAM of this much sufficient memory I will recommend you to take RAM sticks of more speed.  also check out how to fix annoying DISM errors.


On the other hand if you are unable to buy this much memory then I will recommend you to get more ram with less speed.

Two Things to Ensure Before Overclocking RAM

One thing you need to keep in mind that:

If you have overclocked your processor by increasing its base clock, your RAM will also get slightly overclocked. So, in this case you will have to change the memory’s voltage, frequency and timings for better performance.

If you play Rolox, then I have a great news for you. Check out our separate post on how to change fonts and color of text in Roblox.

Before proceeding, You need to make sure of two things.

As a safeguard you need to ensure the current RAM speed and suitable frequency.

And here’s how you’re going to check both of these…

1. Check Your Current RAM Speed

To overclock RAM, first of all you need to check the current speed of the RAM.

To do so, you need to simply open task manager by right clicking the taskbar. Then you need to go to the “performance” tab. There you will find another tab for memory. Click on that and you will be able to see the current speed of the memory modules (RAM).


You can also check RAM speed by using CPU-Z app.

For calculating the RAM speed in CPU-Z app, you will have to double the DRAM frequency shown in the app.

For example:

If the DRAM frequency shown in the app is 1600 MHz, then the total RAM speed will be 3200MHz i.e 1600 X 2 = 3200MHz.

You can check this detailed guide on monitoring CPU/GPU/components temperature.

2. Identify Suitable Frequency/Speed for Your RAM

For overclocking RAM, the most confusing part is to know about the speed you should overclock the RAM to.


All the DDR4 RAM are locked at 2133Mhz.

But most RAM are sold at different speeds like2400Mhz, 2666Mhz, 3000Mhz, 3200Mhz, 4000Mhz etc.

Want to know the best part?

You can even overclock the RAM to a speed more than that of rated speed of the RAM.The rated speed on the RAM’s body is the highest stable speed that is certified by the RAM’s company.

The easiest way to choose the RAM speed is to select the RAM speed less than or equal to the rated speed. Other than that, you can check the other speeds by restating the PC after saving the settings and running some heavy applications like benchmarks.

Jargon You need to know Before Overclocking 

There are some terms you might not have heard before. But you will have to understand this thing now, or else, your overclocking experience will be incomplete.

RAS & CAS: RAS stands for Row Access Strobe & CAS stands for Column Access Strobe in memory modules.

RAS to CAS delay:  The time taken to line up a RAS line and CAS in memory.

CAS Latency: The time which is in between the CPU requesting for data and RAM sending it.

Active to pre-charge delay: The time seized for the memory access. It is also known as tRAS

RAS Pre-charge: The time required to disable one RAS line and active the adjacent. It is also known as rTP.


Best DDR4 RAM Overclocking Techniques

Keep in mind:

There’s no software specific solution to overclock RAM.

Mainly there are two ways to overclock your memory modules. These are by using XMP and by Custom overclocking.

XMP(Extreme Memory Profiles) is a list of preset profiles which you can enable to overclock your memory modules automatically. but there are some problems with it which i will explain later.

So, the better way is the custom RAM overclocking method. In this method you can set the speed,clocks&voltages according to your needs.

Here are the steps to overclock your RAM on MSI motherboard:

  1. Open the bios menu by clicking the “F2” or “Del” button while starting or restarting the PC.
  2. Click the OC tab and you will find XMP (which will automatically overclock your RAM to mostly the highest frequency).
  3. If you disable it then you will be in manual mode.
  4. In manual mode/Xmp disabled mode you will be able to set speed from “Adjust DRAM Frequency” option.
  5. Then restart the PC selecting the “Save and Exit” option (F10 for most mother boards).


How to Overclock RAM on GIGABYTE Motherboards

The steps to overclock your RAM on a gigabyte motherboard are given below:

  1. Open the bios menu by clicking the “F2” or “Del” button while starting or restarting the PC.
  2. In the bios you will find a tab M.I.T where you can overclock your system.
  3. You simply need to select the XMP and click the “+” button to change it.to active manual mode you will disable the manual mode.
  4. You can then select memory frequency (MHz) and click the “+” button to adjust frequency.


Overclocking RAM DDR4 by XMP

XMP stands for Extreme Memory Profiles.

Simply I can say that:

XMP is an Intel technology.And it allows users to overclock their RAM very easily. It lets you choose multiple memory settings by simply selecting a different profile.

I will now discuss about how to overclock RAM using XMP in asus, msi, gigabyte motherboards.


In the motherboard’s bios you will find XMP (if supported) and you will need to enable it to overclock your RAM.

XMP in most cases have an options of 1-3 profiles to choose from. You just need to select your desired profile and restart your PC to experience the new speed of the RAM.

One thing you should know that:

Your PC’s power supply or your RAM might not do well with the speed given by the XMP.

Some times you can even burn your RAM too for this reason. so, there is a risk in using the XMP profile.

It gets worse:

If you are using XMP and you are not sure about the power needed for that speed and your RAM’s capability.

What’s the bottom line?

XMP is only for the High-end RAM power by High-end power supplies

Is RAM Overclocking Worth it?

You have already checked the benchmarks of varieties of  games above for different types of RAM speeds. Higher RAM speeds will also give you better performance while web browsing and other Ram intensive tasks like recurring calculations video rendering, and running different apps.

There are many people who buy expensive PC parts and play games without overclocking the RAM modules. This disallows them to enjoy the full experience of their gaming PC.

Basically normal low priced RAM cannot be overclocked much .Basic motherboards are also unable to overclock the RAM. For people having system like that RAM overclocking isn’t worth it.

But here’s the kicker:

The expensive RAM are made mostly for that high speed. So, expensive RAM buyers need to overclock that RAM to utilize it’s speed.


Better RAM speed can extremely upgrade your gaming PC’s performance and it can ensure you a good gaming experience.

So, you can be sure that your RAM overclocking will be worth it if you are running a overclocking type of system.

Memory Overclocking Problems and their Solutions

There are risks in any overclocking process of the components of a PC. So, you will need to overclock your RAM cautiously.

After overclocking you might find problems like:

Blue screen of death, Restarting/shutting down of PC automatically, PC not turning on properly etc.If you face such problems then you can be sure that, your RAM’s overclocked frequency is not suitable for your PC.

So, you need to change the frequency again by the same method to a safe and stable condition.

If you face error 0x0001 while opening Geforce experience then here’s the fix.

NOTE: You need to overclock the RAM between default speed to the rated speed and set voltages accordingly or you might fry your RAM. I will recommend you not to use excessive voltage.

Advantages and Drawbacks of Overclock Memory

RAM overclocking has some drawbacks too instead of having such great advantages. So, here are some pros. and cons. of RAM overclocking:

  • »The RAM speed is utilized. RAM are more expensive for that more speed. so, you can say the money is fully utilized.
  • »RAM can be overclocked more than the rated speed if it’s perfectly done.
  • »This simple task can increase your PC’s performance to a great extent.
  • »Sometimes the RAM get fried if they are overclocked in a wrong way.
  • »RAM overclocking can reduce the life span of the memory modules to a great extent if the heat sinks aren’t suitable.
  • »RAM overclocking is not worth it if you are using a poor-end system with a good RAM.

Frequently Asked Questions

Some common questions I have been mostly asked about RAM overclocking guide are:

Question: Will two RAM of different brands and speeds work fine?

Answer:  Yes, Two RAMS of different speeds and brands will work.but it’s not recommended to use as you can fall in to troubles like blue-screen of death and PC automatically restarting after booting.Before buying RAM you need to keep in mind that, RAM of different form factors(DDR2, DDR3, DDR4 etc.) will not work at all. In case of overclocking memory modules of different speeds and different brands, you should be selecting the speed of the RAM which has the lowest rated frequency.

Question: Does RAM overclocking brings any change in Gaming performance?

Answer:  Yes, it really does, but you might not find those changes in every games as some games do not require that much of speed.

Question: How much speed can i get from a good Memory Module?

Answer: It depends on it’s ratings you can speed up your RAM up to he ratings or even more than that if the heat sinks of the RAM are good and the power supply is enough including the cooling system.

Question: Does overclocking do any harm to the RAM?

Answer: Not quite, but if it isn’t done perfectly then it may reduce the life of the RAM.

Question: Which intel processor motherboards are the best for overclocking RAM?

Answer: obviously the z270,z370 & z390 for now.

Question: Is XMP suitable for overclocking RAM?

Answer: Yes, but only if you have good cooling system and enough power from you power supply.

Final Thoughts

Some of you might feel afraid to overclock your memory modules. But there is nothing to fear of. You can easily overclock your memory modules following my guide.

Just be careful with the ratings. I will recommend you not to go to a speed level above that unless you have good cooling system and there is enough power left from your power supply.

Any Pro tip for overclocking DDR4 RAM?

Set the clock speeds to the rated speed or slightly above. And for voltages you can set 1.5v dram which is 100% safe. if you face prolems you can set it to 1.15v, 1.25v, 1.3v & 1.4v respectively

So, here’s the deal:

If you have a high-end gaming/workstation PC then you should definitely overclock your RAM.

And for those who are enjoying the stock performance of the RAM, i will say carry on.

But there is no meaning of spending the money on high frequency rated RAM with more price if you aren’t overclocking them.

High speed rated expensive RAM are made for overclocking.

  • MCLK: Real memory clock (half of the effective RAM speed). For example, for DDR4-3200 the MCLK is 1600MHz.

  • FCLK: Infinity Fabric clock.

  • UCLK: Unified memory controller clock. Half of MCLK when MCLK and FCLK are not equal (desynchronised, 2:1 mode).

  • On Zen and Zen+, MCLK == FCLK == UCLK. However on Zen2 and Zen3, you can specify FCLK. If MCLK is 1600MHz (DDR4-3200) and you set FCLK to 1600MHz, UCLK will also be 1600MHz unless you set MCLK:UCLK ratio to 2:1 (also known as UCLK DIV mode, etc.). However, if you set FCLK to 1800MHz, UCLK will run at 800MHz (desynchronised).

  • Ryzen 1000 and 2000's IMC can be a bit finnicky when overclocking and can't hit as high frequencies as Intel can. Ryzen 3000 and 5000's IMCs are much better and are more or less on par with Intel's newer Skylake based CPUs ie. 9th gen and 10th gen.

  • SOC voltage is the voltage to the IMC and like with Intel, it's not recommended to leave it on auto. Typical ranges for this value range around 1.00V and 1.10V. Higher values are generally acceptable, and may be necessary in stabilizing higher capacity memory and may aid in attaining FCLK stability.

  • By contrast, when SOC voltage is set too high, memory instability can occur. This negative scaling typically occurs between 1.15V and 1.25V on most Ryzen CPUs.

    There are clear differences in how the memory controller behaves on the different CPU specimens. The majority of the CPUs will do DDR4-3466 or higher at 1.050V SoC voltage, however the difference lies in how the different specimens react to the voltage. Some of the specimens seem scale with the increased SoC voltage, while the others simply refuse to scale at all or in some cases even illustrate negative scaling. All of the tested samples illustrated negative scaling (i.e. more errors or failures to train) when higher than 1.150V SoC was used. In all cases the maximum memory frequency was achieved at =< 1.100V SoC voltage.
    ~ The Stilt

  • On Ryzen 3000, there's also CLDO_VDDG (commonly abbreviated to VDDG, not to be confused with CLDO_VDDP), which is the voltage to the Infinity Fabric. SOC voltage should be at least 40mV above CLDO_VDDG as CLDO_VDDG is derived from SOC voltage.

    Most cLDO voltages are regulated from the two main power rails of the CPU. In case of cLDO_VDDG and cLDO_VDDP, they are regulated from the VDDCR_SoC plane. Because of this, there are couple rules. For example, if you set the VDDG to 1.100V, while your actual SoC voltage under load is 1.05V the VDDG will stay roughly at 1.01V max. Likewise if you have VDDG set to 1.100V and start increasing the SoC voltage, your VDDG will raise as well. I don't have the exact figure, but you can assume that the minimum drop-out voltage (Vin-Vout) is around 40mV. Meaning you ACTUAL SoC voltage has to be at least by this much higher, than the requested VDDG for it to take effect as it is requested.
    Adjusting the SoC voltage alone, unlike on previous gen. parts doesn't do much if anything at all. The default value is fixed 1.100V and AMD recommends keeping it at that level. Increasing the VDDG helps with the fabric overclocking in certain scenarios, but not always. 1800MHz FCLK should be doable at the default 0.9500V value and for pushing the limits it might be beneficial to increase it to =< 1.05V (1.100 - 1.125V SoC, depending on the load-line).
    ~ The Stilt

    • On AGESA or newer VDDG is separated into VDDG IOD and VDDG CCD for the I/O die and the chiplets parts, respectively.
  • Below are the expected memory frequency ranges for 2 single rank DIMMs, provided your motherboard and ICs are capable:

    RyzenExpected Effective Speed (MT/s)
    10003000 - 3600
    20003400 - 38001
    30003600 - 3800 (1:1 MCLK:FCLK)
    3800+ (2:1 MCLK:FCLK)
    • With more DIMMs and/or dual rank DIMMs, the expected frequency can be lower.
    • 13600+ is typically achieved on a 1 DIMM per channel (DPC)/2 DIMM slot motherboard and with a very good IMC.
    • 1DDR4-3400 - DDR4-3533 is what most, if not all, Ryzen 2000 IMCs should be able to hit.

      On the tested samples, the distribution of the maximum achievable memory frequency was following:
      DDR4-3400 – 12.5% of the samples
      DDR4-3466 – 25.0% of the samples
      DDR4-3533 – 62.5% of the samples
      ~ The Stilt

    • 2 CCD Ryzen 3000 CPUs (3900X and 3950X) seem to prefer 4 single rank sticks over 2 dual rank sticks.

      For 2 CCD SKUs, 2 DPC SR configuration seems to be the way to go. Both the 3600 and 3700X did 1800MHz UCLK on 1 DPC DR config, but most likely due to the discrepancy of the two CCDs in 3900X, it barely does 1733MHz on those DIMMs. Meanwhile with 2 DPC SR config there is no issue in reaching 1866MHz FCLK/UCLK.
      ~ The Stilt

  • tRCD is split into tRCDRD (read) and tRCDWR (write). Usually, tRCDWR can go lower than tRCDRD, but I haven't noticed any performance improvements from lowering tRCDWR. It's best to keep them the same.

  • Geardown mode (GDM) is automatically enabled above DDR4-2666, which forces even tCL, even tCWL, even tRTP, even tWR and CR 1T. If you want to run odd tCL, disable GDM. If you're unstable try running CR 2T, but that may negate the performance gain from dropping tCL, and may even be less stable than GDM enabled.

    • For example, if you try to run DDR4-3000 CL15 with GDM enabled, CL will be rounded up to 16.
    • In terms of performance: GDM disabled CR 1T > GDM enabled CR 1T > GDM disabled CR 2T.
  • On single CCD Ryzen 3000 CPUs (CPUs below 3900X), write bandwidth is halved.

    In memory bandwidth, we see something odd, the write speed of AMD's 3700X, and that's because of the CDD to IOD connection, where the writes are 16B/cycle on the 3700X, but it's double that on the 3900X. AMD said this let them conserve power, which accounts for part of the lower TDP AMD aimed for. AMD says applications rarely do pure writes, but it did hurt the 3700X's performance in one of our benchmarks on the next page.

  • Expected memory latency range:

    RyzenLatency (ns)
    100065 - 75
    200060 - 70
    300065 - 75 (1:1 MCLK:FCLK)
    75+ (2:1 MCLK:FCLK)
  • On Ryzen 3000 and 5000, high enough FCLK can overcome the penalties from desynchronising MCLK and FCLK, provided that you can lock your UCLK to MCLK.

    Here's How to Overclock PC RAM: But Should You?

    Getting RAM for your PC is a necessity. Although, if you don't run it at its maximum capacity, you are losing out on plenty. Every single program stores data in RAM for a while for faster accessibility. With an overclocked RAM, you can increase the performance of your PC.

    You can optimize your RAM by tweaking a few settings in your BIOS. By doing this, you are removing the memory speed cap set by the manufacturer. In this article, we will show you how to overclock your PC RAM, with its benefits and drawbacks.

    How to Overclock Your PC RAM

    Before you begin overclocking your RAM, there are a few things you need to know. RAM overclocking might be a little more complicated than overclocking a GPU or CPU. On the plus side, it doesn't generate as much heat as GPU or CPU overclocking.

    DDR4 is the norm with RAMs these days. The speed is around 2133MHz or 2400MHz, coming from a manufacturer. Every program needs to access RAM to run on your PC.

    RAMs use Serial Presence Detect to talk with the computer. It consists of a set of operating frequencies and timings. It is available on almost all the DDR4 RAM sticks and is known as the JEDEC specification. However, manufacturers like Intel have some tricks up their sleeves to cheat this system. They use a different profile called XMP.

    XMP stands for eXtreme Memory Profile. As a result, Intel offers the ability to overclock RAM straight out of the factory. Still, it isn't the best overclocking you can get out of that RAM. You can push the boundaries to further overclock it from the manufacturer's capped frequency.

    Some Useful Tools for Overclocking RAM

    There are several tools to assess your RAM's information. Here is a list of three tools that let you get information regarding your RAM before overclocking.

    • CPU-Z: CPU-Z is a free tool to assess and take notes of your DRAM before overclocking. If you head over to the Memory tab of CPU-Z, you can find all the information there. Additionally, there are XMP settings that your BIOS uses, located under the SPD tab.
    • Memtest86+: This is more of a testing tool used for stress testing on your PC. It comes with a wide variety of options to run stress tests.
    • XMP (eXtreme Memory Profiles): As mentioned above, XMP is an additional profile used by Intel to validate overclocking settings. Using XMP can allow the firmware to configure DRAM voltages and latencies automatically.

    NOTE: You can always clear or reset your RAM settings if things don't work for you. If your PC boots up, yet is unstable, you can revert to previous settings in the BIOS. If the PC doesn't boot up at all after a second restart, try to clear the CMOS on your motherboard to reset BIOS settings to default. If you don't know how to do that, consider checking your motherboard's manual.

    There are two methods to overclock your CPU: using XMP and manually overclocking.

    1. Using XMP to Overclock RAM

    Intel gives you the option to overclock using the XMP profile. To overclock your PC RAM using the XMP method, follow these steps:

    1. Install and open CPU-Z on your PC.
    2. Note down the DRAM frequency and timings along with timing tables from the SPD tab.
    3. Restart your PC and enter BIOS mode.
    4. Once entered into BIOS, head over to the AI Tweaker / Extreme Tweaker / D.O.C.P. option, depending on your motherboard.
    5. Choose the right XMP profile that matches the advertised specifications of your RAM.
    6. After making the necessary changes in the BIOS, save changes and restart your PC.
    7. Once the PC restarts, perform stress tests to check its stability.
    8. If things don't work out well, make the necessary changes in BIOS and stress-test again.

    If the system is stable, then you have achieved overclocking of your RAM using XMP.

    2. Using Manual Settings to Overclock RAM

    Following the above steps will give you a good idea of where the system is stable. You might want to write down the right timings, frequencies, and speeds. In this method, we will boost the voltage of the RAM, leading to better RAM performance.

    If you want to take advantage of the manual settings to overclock your RAM, follow these steps:

    1. Reboot your system into the BIOS and navigate to AI Tweaker or equivalent settings of your BIOS, as mentioned above.
    2. Instead of selecting an XMP profile, select the Manual settings. This will unlock additional settings for you.
    3. You should slowly start increasing the DRAM voltage in 0.015V increments. Similarly, increase the CPU VCCIO and CPU System Agent voltages in 0.05V increments. NOTE: Make sure you don't overdo them; it may cause your components to fail.
    4. For DRAM timings, check the timings that you noted down while performing XMP overclocking.
    5. After making the necessary changes in the BIOS, save changes and restart your PC.
    6. Once the PC restarts, perform stress tests to check its stability.

    If things don't work out well, make the necessary changes in BIOS and stress-test again. In the event that your system is stable, then you have overclocked your RAM successfully.

    Should You Overclock Your RAM?

    RAM is necessary for any system. Every program on your PC uses a certain amount of RAM to boot up faster and run in the background. And that's where the actual use case of faster RAM becomes apparent. It's not always the CPU and GPU that improve your PC's performance: it's also your PC's RAM speed that results in better performance.

    You might not see the results as a day-to-day user, but if you are the one whose work relies highly on RAM, then overclocking is a good option for you. Other than those circumstances, if you are a gamer, you'll see the actual effect of an overclocked RAM. The frame rate of your games increases drastically and might improve your gameplay.

    Is Overclocking RAM Bad for Your PC?

    Technically, overclocking RAM isn't bad for your PC if you are doing it to the RAM's actual limits. If you overclock the GPU or CPU, you must worry about noise and the cooler's capacity to handle such clock speeds. However, that's not the case with overclocking RAM.

    Overclocking a RAM, even at wrong frequencies, will give you an error at most. Later, you will need to tweak the frequencies or voltages to stabilize the RAM. There's no issue of overheating, so you need not worry about that.

    But doing this on a laptop is a bit risky. You might want to check for the CMOS reset option, so that you can reset your BIOS settings if something goes wrong.

    Overclocking PC RAM: Success

    So that's how you can overclock your PC's RAM. But always remember that even though it's risk-free, you must have a backup RAM for if something goes wrong at any point. We recommend you to overclock your RAM only if your work involves a lot of RAM usage, like video/graphics editing, gaming, etc.

    The method for overclocking RAM is different from one manufacturer to another. So do an ample amount of research before hopping onto overclocking your PC's RAM. If you are afraid to overclock your RAM, you can always get an overclocked RAM from any online store.

    There are several programs you need for stability testing, benchmarking, verification and a readout of your RAM IC's and PCB.

    Dual rank 2x vs Dual Rank 4x.

    When purchasing a DDR4 RAM kit to consider is your capacity in GB as well as how many DIMMs it will populate. For overclocking a DDR4 kit of 2 is best however if you need more or just want more capacity with 32GB or more you can either end up with a 4 x 8GB kit or a 2 x 16GB kit. Most consumer CPU's will support dual rank like the Intel 9900k and the AMD 3600X. This means if you use more than 2 DDR4 sticks, you will share each channel. This will put more stress on the internal CPU IMC(Internal Memory Controller). Thus for extreme overclocking, Dual Rank DDR4 kits are better. When using Dual Rank kits, make sure you populate the 2nd and 4th DIMM slots or reference the motherboard manual.

    Another consideration to make when using 4 DIMM slots on dual-channel motherboards is the topology of the motherboard traces. The traces leading to your DIMM slots can either be Daisy chained or use T-Topology. This is however not commonly advertised to guesstimate check the motherboard QVL. When the highest validation on the motherboard for RAM is with a kit of 4, then most likely that motherboard is using T-Topology. If the motherboard highest validation on the motherboard for RAM is with a kit of 2 sticks, then it is most likely Daisy chained. This is also a good indication of the motherboard quality. Even when using a RAM kit of 2 sticks, T-Topology is better for extreme overclocking(4000mhz or higher). But again for extreme overclocking it is always better to use two sticks of RAM on dual-channel for the best result.
