7800 XT not detected MSI PRO B650 w/ 7600X - About to tear out what little hair I have left
Posted by Southern_Most9129@reddit | buildapc | View on Reddit | 11 comments
So did a new build last night of a MSI PRO B650, 7800 XT, Corsair 32GB DDR5 RAM CL30, 7600X CPU, and a Corsair RM750e. Everything went well up until the first time boot. I just get a little bright white LED saying it does not detect GPU. Long story short I tested an old 1060 Nvidia in the x16 slot and BAM, works no problem and goes right into the BIOS, everything shows its all running and functional. Same with an old RX 580, works no issue.
Oddly enough, putting the 7800 XT in the x4 slot works, so I installed OEM Windows on a SSD thinking i would get this done and then swap the card back to the x16. Putting it back into the x16 slot does nothing and now im back to square one.
Any suggestions because now I am REALLY regretting this MSI mobo purchase because apparently this is common but no one ever seems to have an answer. Does anyone have a solution?

I’ve spent the last 10 hours trying to get my 7800xt to work in the top slot of my b650 tomahawk I am pissed. I’m going to try revert the bios as a last ditch effort now.

no fucking way is this a msi problem i have tried MSI MAG B650 TOMAHAWK WIFI and the MSI PRO B650-S WIFI.
i thought it was just me but have you have the same problem where my XFX RX 7800xt isn't detected but the 1050ti and my friends 3060 is being detected
u/Southern_Most9129 are you both having the same problem?

Yeah but recently an update was provided by msi which supposedly fixed my friend's issue.

its a msi and xtx 7800xt compatibility issue. very unlucky for me on there website it says
Known Issues:
MSI B650 Motherboards - There may be a compatibility issue in regards to MSI B650 platform motherboards. If you are experience No Post with a new installation, or after updating your motherboard BIOS, revert to you motherboard BIOS to the version with "AGESA ComboPI 1.0.9.0 ." listed in the description of the BIOS release notes.

Just today, my friend got the same motherboard as yours and paired it with an RX 7800 XT. However, for some reason, the RX 7800 XT isn’t compatible with the motherboard. Upgrading or downgrading to BIOS version 7E26v191 (Beta version) dated 2024-01-04 works, but any BIOS version released after that date causes the board to not boot with the RX 7800 XT.”

Just to add. ive tried setting the PCIe lanes to x8 - x4 - x4 since that was suggested, but no dice.
