BIOS setting for C32 memory on the ROG STRIX

[rtfmoz]

I am having some trouble with memory testing on ROG STRIX Z690-E GAMING WIFI using Corsairs Vengeance DDR5 6400MT/s C32 DRAM (CMH32GX5M2B6400C32). The computer has been used with no issues using a different set of DRAM. This is a new set being installed.

I have postedMemtest86 how to interpret describing the issue with the DRAM which is reflecting errors on the slot rather than the memory. I am using the XMP settings of 32-40-40-84. This the DRAM info from Memtest86 v11.1 Pro Memory and System Info. I am looking for advice on BIOS settings for this memory above and beyond "XMP I" to stabilise this memory.

im confused. are you not setting XMP to enabled? are you trying to manually enter everything in? are you not stable with regular xmp settings? you give no info on what is happening.

The linked post describes the issue I am having with the memory.  Memtest86 how to interpret With XMP settings I am getting errors. When I swap the memory between each other I would expect the errors to follow the stick but that is not happening, I get errors on the same slot. This is a machine I have being using for a while with a pair of matched DDR5 6400MT/s C36 SDRAM. Now I have been given a new pair of matched DDR5 6400MT/s C32 SDRAM and I am wondering if there is some tuning that needs to happen to make these work reliably.

I have updated the original post to make it clearer.

Hi @rtfmoz 

You haven't stated which CPU. Is the kit listed on the motherboard QVL? Kits at or near the top of the validation list for a given density may often require concessions if XMP profiles do not work.I often advise users to purchase a kit 2 to 3 frequency bins below the maximum validated speed for a given density for the best chance of "plug and play" success.
