Hello,

I have the 7900X and 7980XE, and two Rampage VI Extreme boards.

On neither system, I have managed to get 4000 MHz RAM stable with RAM Test.

Corsair CMD32GX4M4E4000C19 - not stable with XMP (not on QVL of R6E but on QVL of R6A)
G.Skill F4-4000C18Q2-64GTZR - cannot even boot with XMP.

I have tried raising VCCIO, VCCSA, VCache and DRAM voltage but it seems nothing really helps. Both kits seems to be stable at around 3800C17. The Dominator kit can do 4000C17 using only two modules on my Rampage VI Apex with the 7740X chip.

Any tricks or will I just have to wait for Cascade Lake-X for possibly better memory support? :cool:

It's good to cover RAM Test as well as GSAT, RAM Test is very quick at picking up errors, but not always a good idea to limit yourself to one method. Both will stress the memory differently. Also RAM Test is better equipt to stress cache.
