How do I make the 192GB Corsair Memory kit work on my Z790 Maximus Hero?

[rene_bonvanie]

I bought the following kit based on the CPU/Memory configuration tool:

CORSAIR

CMH192GX5M4B5200C38

4x 48GB

I got two sticks to work fine, but all tests I run with four sticks fail - including Memtest86 in the BIOS in step 8.

I upgraded to BIOS 1202, and that didn't change anything.

What BIOS parameters do I need to use to make this work? It is an officially approved configuration, after all! Why doesn't ASUS publish this alongside their approved memory?

Hello,

1) Does the system pass Memtest86+ at Optimised Defaults (No XMP)

2) If so, enable XMP II and see if this helps stability

3) Set CPU System Agent Voltage value between 1.30v - 1.35v

4) Go to Extreme Tweaker > Advanced Memory Voltages set Memory Controller Voltage to value between 1.35v - 1.4v

See if this aids stability. 4x48GB will need a reasonable IMC

Sorry, it took a few days, but after testing your proposed solution I found it to work well. I settled on setting the DDR Frequency to 4400 for this kit. Thank you so much for your advice.
