Howdy!

I just updated my bios to version 7C35vA7 and am having trouble with XMP. Before my Ryzen 7 5800x, I had a Ryzen 5 2600x as my CPU. With the R5 I was able to enable XMP all the way up to 3600mhz (unstable) and 3333mhz (Stable). After the Bios update and new CPU I cant boot with any XMP and am now stuck with my ram running at 2667mhz. The RAM in question is Corsair vengeance RGB Pro 3600mhz.

I feel your pain. All we can do is to wait for the release of better beta or solid final BIOS that hopefully fixes all problems. In the meanwhile you can also try Thaipoon + Dram Calculator combination (try "safe" settings) and manually insert the RAM timings in BIOS.

Hi,

in order to solve the A-XMP issue with RAM that higher than 3200 MHz, you need to update your BIOS with one of the Beta ones starting with .A82.
Please, note that latest one on site now is .A85 which will allow you to activate XMP on that RAM and mostly will work fine unless you want to tweak with OC your CPU or OC your RAM beyond 3800 MHz.

Thx.

I have the same RAM, the AMD QVL version.
I have two kits from Amazon, with serial numbers just 130 away from each other, so for all intents and purposes, a 4 x 8GB single rank kit.
Could never get it stable over 3200Mhz, but if I remove one of the kits, I can run XMP 1 in the BIOS.
This is a very well known issue mostly (correct me if needed) attributed to the CPU on board Memory controller.
As the BIOS is updated more and more, we should see this issue disappear.
Currently I just run the 2 sticks at 3600Mhz and it runs fine with the latest BIOS (V8 and V93(Beta).
