XPM - Crash (Full SLOTS 4xRam) Rog STRIX Z790-E Gaming

Hi.
I decided to get a new computer this week, but I'm having some compatibility problems between bios and rams.
I bought an ASUS ROG STRIX Z790-E Gaming motherboard and I'm using an Intel i9 13900k processor.
In the meantime, I checked the ram compatibility for this board and processor and decided to buy some RAM Corsair DOMINATOR TITANIUM RGB 6400 MHz 4x 48 GB with the SKU code: CMP96GX5M2B6400C32
At the moment I'm having a lot of stress problems, and not boot ( led code on mian :53 ), when activating XMP I or XMP II in the bios (ver.BIOS 2102) .

If I set the value to automatic, I'm running at a speed of 4800mhz and run fine, but when I set it to 6400, I start having these problems.

Another test I did was to remove 2 slots(A2,B2) and run the test with 2x48 instead of 4x48 at 6400/6600 and it was perfect.

MOTHERBOARD: ASUS ROG STRIX Z790-E Gaming
PROCESSOR: INTEL-I9 13900K
RAM MEMORY: CORSAIR DDR5 4X48 6400MHZ C32 - CMP96GX5M2B6400C32

Hi @JokerLee_2410

Sorry to say, but you won't get those kits working together. Combining/mixing memory kits (even if the same PN) is not supported or recommended by the memory or board vendors. Remove one kit and retest.

See here for more information regarding XMP/EXPO and overclocking information.

Thank @Silent_Scone ,
😞 yep, i also think  "XMP" not good withs 4 slots. 
I need help from someone with experience to OC manually (>6000 bus) 😞 

You likely won't, and that sort of "support" requires both parties to have a reasonable grasp on DRAM, voltages and memory timings.This is why XMP support exists in the first place, to reduce tuning needed. I make a habbit of not providing suggestions for people combining memory kits, and all the relevant information as to why is in the link provided.

The maximum qualification for that density (4x48GB) on 13th Gen for the Strix-E is 5200MT. This means that ASUS were unable to validate anything faster than this in that capacity and, more than likely, there isn't a kit on the market at that frequency and capacity for good reason (CPU IMC capability).
