Mixing different DIMMs can be problematic, as can more than 2 DIMMs in total (it's unclear if you were trying a 3 or 4 DIMM configuration). If you really need/want to go beyond 2x32, 4 matched DIMMs would give you the greatest chance of success, but may well require running them at reduced speed or looser timings. Currently, there are no validated 4 DIMM configs on the ROG Maximus Z790 Hero Memory QVL (the "socket support" column tells you how many DIMMs are in the validated config). Using parts from the QVL should also give the greatest chance of success.
Do they work ok with XMP disabled? XMP is overclocking, so adds to the complexity/difficulty.
Yes I know that it is impossible to overclock when, my configuration is:
- 2x16GB DDR5 4800
- 2x32GB DDR5 4800
at the minimum non-overclock or non-xmp it should be working, it was working with the original bios but not with the 703 version.
it should have worked in safe mode. I was using the memory as documented (maybe I read it wrong):
- dimm_A1: ADATA 16GB
- dimm_A2: Crucial 32GB
- dimm_B1: ADATA 16GB
- dimm_B2: Crucial 32GB
is that a supported configuration ? How do you force it to use non-xmp when it does not boot.
It could also be that my memory modules are not on the supported memory.
