I went back to 1003 , only thing that works for me is XMP1 then under RAM timings set MODE to MODE 2, I am stable at 4600 if I go to 4800 it is a BSOD on tartup

This BIOS makes things worse for me when XMP in engaged, instant BSOD on startup, gone back to the previous BIOS with 4 X 16 sticks of Corsair Vengeance DDR5 4800 XMP 1 MODE 2 stable at 4600mhz

Hope this helps...

Well its been several days now with lots of gaming and happy to report that my Corsair LPX DDR5 4800 64gb (4 x 16) is able to use XMP 1 but at a reduced ratio of 4533MZ which is better than before...

They are on to something with this BIOS, I had to run my Corsair LPX 4800 4 x 16gb of DDR5 at 4266 to maintain stability with XMP 1 with the previous BIOS, originally anything over 4400 was an...

I posted on OC3D TV latest Youtube video about DDR5 that reviewers have not picked up on the DDR5 4 dimm slot XMP problem yet and this was the reply:

" Most of us dont have 4 matching DDR5 sticks...

For now enable XMP1 and scroll down and reduce the MZ to 4266, that should be stable

Yes exactly, those of us with 4 dimm slots populated seem to be getting more errors, hope ASUS is aware of this or if some Admins have access portal to Asus directly they should report this error. I...

Just adding my moan, Corsair Vengeance DDR5 4800mhz 64GB (4 X 16GB), XMP 2 is an instant BSOD, memtest pass. Bios tested 803 / 811
XMP1
4800mhz = BSOD,
4400mhz System Stable until playing a...

I got this with the 803 and the beta 811, back on 803 at the moment, 4 dimm slots populated with 16gb x 4 DDR5 Corsair vengeance 4800mhz. The only XMP setting that will work is if I reduce the MHZ to...

I found this article after ElectronSpin posted above in regards to 4000 being the official speed if all ram slots are populated, he is right and this is why xmp is not working for most of us using...

I found this article after another forum poster stated the official speed is 4000 if all ram slots are populated https://www.anandtech.com/show/16959/intel-innovation-alder-lake-november-4th/4 <---...

Ah that is interesting, I got it stable using XMP 1 but only at 4266, anything over that is Russian roulette :D

Same here 4 x 16gb (64g) of Corsair Vengenace 4800, only XMP value I can use is 4266mhz which is stable in games, Watch Dogs Legion is a good game that will let u know of stability issues, Valhalla...

The only way I managed to get a stable XMP 1 was to reduce my ram frequency to 4266mhz, the RAM is Corsair DDR5 4800 (64GB), 4400 works fine until u load a game, anything over 4400 is an instant...

I am having the same problem Hero z690 with a 12900 on Windows 11 bios 803 with 64g DDR5 Corsair Vengeance 4800, XMP works fine until I play a game then 10 mins in the game crashes, under ram timings...

Yeah but like I mentioned I do not have any M2 / 4 drives and it still only gave me 4 hard drives out of 6, it's all sorted now but it was a massive headache :)

Yeah I do not use M.2 drives, I only have 5 SSDs and one SHD :)
