Hi all, I need your assistance and guidance please. I am not an experience overclocker, but want to learn and push my system to maximize things. I currently have 2 Kits of Gskill 48GB CL26 6000 RAM Kits and I am using an MSI X870e Godlike and 9950X3D. 1 Kit runs beautiful at Expo Settings, but when I install the second kit it does not pass any stress test. I know and have read a lot that this is very difficult and I need to manual tune my RAM. The question is how do I manually tune it?

What I have done so far is the following:

  1. I have tried to pick several already established profiles in my "Memory Try It" Bios from 5600 to 6000+ and all do not pass any stress test.

  2. The only Bios profile that worked fine was the 5600 CL38 which I know its far away from the Expo profile of CL26 6000, but passes all tests and has been working well.

Question, how can I manually tune it to finish somewhere in the middle? I have attached both Zen timings from CL38 5600 and CL26 6000.

If I am on an impossible mission I will just sell/return my second kit and stick to 1 kit CL26 6000, but want to give it another shot with the expert community. One reason why I bought this board was to be able to tinker and learn overclocking and push my system.

Lastly confirming my PC is working perfectly with the 9950X3D, 5090FE, etc. all watercooled so reason to push its limits. I know how to OC/UV my CPU and GPU, its RAM I am a bit behind.

Thank you in advance and helping a noob on RAM Overclocking.
