Asus Crosshair VIII 3101 Beta Bios out !

[Kelutrel]

just flashed 3102 and wouldn't boot with 3800/1900, flashed back to 3101 and it booted fine

Weird, I also am at 3800/1900 and works ok with both bios versions, don't know

3102 booted fine for me with a 5950X and 4x16GB 3600MHz CL14-15-15-35 1.45V RAM kit.

It won't post if I set CMD2T to 1T though. And this is B-Die.

I do not move from 2206 until something really stable comes out that I can make my hero viii and ryzen 3950x work with 128gb of ram at 36000mhz

Hi Karmal,
sorry i didn't understand: did you try bios 3003 with settings suggested by me?

CPU Ryzen 7 5800X here.

I cannot even boot with BIOS 3102 at 3800/1900 either. Also, with both 3101 and 3102 I sometimes get a USB over powered error after a clear CMOS is performed (with 3101 it happened just after flashing, with 3102 after a manual Clear CMOS was done to recover boot after trying 3800/1900). I have to switch off my PC and cut the power to make it even boot again.


I really hope both AMD and ASUS step up their game, because this is underwhelming to say the least.

I am using BIOS 3102 right now
and i have 5800X with 1900 fclk and 3800mhz cl14 4x8GB (4 dimms)
enable docp what ever they call it

go to dram timing leave the first 5 because it will be config by the docp
Now change tRC 52 tFAW 46 tRRD_S 4 tRRD_L 10

this the voltage that i use
SOC 1.125

vddg ccd 0.980

vddg iod 0.980

clod vddp 0.850

PLL v1.8 i changed it to 1.81

For better result first you use 1833fclk and then f10 so your motherboard use the voltage we sit
After the reboot with the new settings ,enter the bios again and use 1900fclk and f10 again.

no WHEA errors or bosd at all for 1 month playing all day and 0 errors in memtest from BIOS 2701>3001>3101>3102 same settings

Tried a second set of RAM (different model) and still no post with DOCP on, works fine with everything set at Auto. Then read @lahlksa post, bit of research online, used the DRAM calculator and tried its recommended SoC voltage of 1.025V and boom it posts fine. Never messed with these settings before so a bit nervous that I'm going to cook something. Also didn't change anything else, just DOCP on and SoC to 1.025V.

Anyway let's see how stable it is and if I get WHEA before the next BIOS get's released. Guess the memory controller is just not getting enough power to cope with the overclocked 3200 RAM.

Anybody know the safe voltage range for SoC with a Ryzen 5950x?

How's Zen2 stability for Version 3102 Beta?

Thanks for the input. I'll give it a try
