Overclocking your RAM can be a complicated task for many people. Many factors have to be considered when overclocking RAM. With the introduction of DDR5, some people may also wonder if the overclocking process would be the same as DDR4 or what voltage will be needed.
MSI Memory Try It! made DDR4 overclocking a lot more simplified. Its overclocking profiles serve as great references for beginners. Now, Memory Try It! supports DDR5 too. With the profiles, you can reduce the time spent in finding the best configurations.
Load the Profile and Go
Memory Try It! is fast and easy to use. What you need to do is pick a profile from the dropdown menu and try it out. It can detect the RAM chip and provide corresponding overclocking profiles, including high frequency and tight timings profiles. Take the Corsair Vengeance DDR5 kit for example. Memory Try It! provides high frequency such as DDR5-5800 CL38 profile and tight timings profile like DDR5-4800 CL36 for you to try out.
We recommend you start with a frequency that is higher than the XMP and see if it's stable. Then try some tight timing profiles. You can use AIDA64 to test the RAM performance for each profile. After several tries, you will be able to find out the best frequency and timing configurations for your DDR5 kit.
For Even Higher Performance? – Tighten the Main RAM Timings Manually
If Memory Try It! doesn't meet your requirements, you can go further with tighter timings. One of the more effective ways to have better performance is to work on the RAM's timings. It's enough to focus on these three main timings: tCL, tRCD, tRP. You can try to lower the value by 2, such as lower the tCL from 40 to 38, and test the performance improvement and stability. If it's stable, you can go further with even tighter timings like 36 until it’s unstable.
Useful Voltages for RAM Overclockingy
When you’re pushing the RAM, you may need to consider altering the voltages. Some voltages are helpful for higher frequency and tighter timings. For DDR5 overclocking, what voltages are helpful? You may have already noticed that several voltages are adjusted according to the Memory Try It! profiles. These voltages include “CPU SA Voltage”, "CPU VDDQ Voltage", "DRAM Voltage" and "DRAM VDDQ Voltage". If you’d like to have more performance from your RAM, you can work on altering the voltages.
What's the recommended voltage? You can compare the voltage difference between DDR5-5800, DDR5-6200, DDR5-6400 in the Memory Try It! profile and see how the voltages change. This will give you a hint on how to overclock your RAM. Here are the voltages for some Memory Try It! profiles. You can start with the Memory Try It! voltage, and increase or decrease the voltage based on your DDR5 kit.
Note: The CPU SA Voltage is locked on non-K 12th Gen Intel Core processors and it will limit the RAM overclocking capability.
Higher RAM Frequency or Tighter Timings?
The purpose of overclocking RAM is to get as much performance as possible. Compared to CPU overclocking, RAM overclocking is more complicated. You have to work on both RAM frequency and timings. What do frequency and timings do to RAM performance? The charts below show how the RAM bandwidth and latency scale with RAM frequency and timings.
