For overclockers from Team Red, 1Usmus' DRAM Calculator is a very helpful tool for determining RAM overclocking figures to use in your system. On Thursday, 1Usmus delivered version 1.7.0, and its main improvement is support for AMD Ryzen Threadripper 3000-series CPUs. Download details are on the enthusiast's forum post at

You can often do simple RAM overclocking by enabling a supporting kit's XMP profile to achieve intended speeds. But if you  want to get into advanced territory, 1Usmus' DRAM Calculator is there to help. Just be sure to have read our PC Memory 101 manual before even contemplating getting started.

Using 1Usmus' tool, you enter the details of your system, and the calculator will figure out which settings would allow for the best memory overclocks and then implement them. Of course, it'd still be important to take all the necessary precautions, such as stability testing after every change and awareness that this may void your hardware's warranty.

For more details on what's new with the DRAM Calculator's latest version, see the changelog below: 

  • Added the functionality to read current memory timings for Zen 2 (AM4 CPU socket).
  • Added a memory bandwidth test (Read and Write).
  • Added an Inter-Core Latency test (AM4).
  • Improved the accuracy of Random and Custom latency test.
  • Some changes in the suggested CAD_BUS settings. This could offer a significant improvement in stability for configurations with two or more RAM modules.
  • VDDG setting is now divided into 2 independent settings : VDDG IOD and VDDG CCD voltage (as in AGESA 1004B bioses).
  • "Compare timings" now works for Zen 2 (AM4).
  • Added support for 3000-series Threadripper CPUs (Castle Peak).
  • Minor user experience GUI changes.
  • Added support for Hynix DJR (a new CJR revision that has backward compatibility with classic CJR).
  • Minor bug fixes
