Hello my friend,

I also have the CSM bug with my Asus ROG Strix RX580 TOP 8GB GPU. If I update motherboard BIOS, CSM is enabled and then my screen works only after booting to Windows and to disable, I must replace GPU with an old (9800GT in my case) legacy GPU, disable CSM and then replace GPU. Can you update my firmware with latest GOP BIOS, too? I attach it

@kostas-k your attachment is missing. It hasn't been mentioned, but all the previous bioses appear to have been modified for mining. Assumedly, yours is the same.

There's 4 verified vbioses for the TOP model. Take note of the ram type you have (hynix/samsung/micron) and use the appropriate vbios.

Take a dump of your existing bios first just in case

Yuo are correct, forgot to press "Upload"

Here is my file, stock and not modified, if you can update I would be grateful, I have Samsung RAM

On one file, I see version VER015.050.000.001.000000
AS09.bin, while mine has RS06, you think it's the updated one?

@kostas-k your bios is 67DFHB.15.50.2.1.ASB2

curiously, I couldn't find any reference of it on the internet. Never seen one that wasn't AS## either. Maybe the B is beta? Or it's hex? Did you buy this new or was there a chance the vbios was modified by a previous owner?

Either way, there's 2 verified t8g/samsung vbioses in the techpowerup vgabios db, and 5 unverified (2 of which are immediately identifiable as modified based on 1750/2000 timings, and another with a different samsung string). Of the remaining two unverified, they vary in temp target (assumedly normal vs quiet vbios).

Do you have an igpu/other gpu or ability to externally flash (eg ch341a+soc8clip) in case things go sideways? If so, it might be easiest to just flash a different t8g/samsung vbios and see if it works for you.

edit: hmm took another look and your bios is for the newer "K4G80325FC" vs "K4G80325FB"

I have bought from a friend, surely no modified bios. I have also noticed the ASB2 instead of AS##. I have a second igpu and ch341 flasher. I will try and check

Thanks
Their

I did find another asb# https://www.techpowerup.com/vgabios/225901/225901 with the same newer K4G80325FC (mostly found on rx590s, but I guess newer 580s too). I'd flash a strix o8g (triple) instead of the dual though (triple 08g is the same as t8g at least, just not as high bin), but I haven't seen one of thsoe bioses yet
