This issue isn't happening on my system either!
Hey guys, having some issue with my newly adopted 3080. My specs are a Z490 Tomahawk, 10700KF, RTX 3080, 16GB Vengeance Pro RGB, RM850x. So this issue is ; I purchased a Gigabyte 3080 Vision OC LHR to upgrade my 2070S a month ago and it won't post with the 3080 in the top PCIe x16 slot, it posts/games fine in the bottom PCIe x4 slot. But here's the funky part, I've confirmed my 3080 works in 4 other PC's (x2 Gen 3.0 PC's, x2 Gen 4.0 PC)... But I've also confirmed my other parts are working as I've had a 2070S, 1650, 970 AND another 3080 in my PC working fine! The things I've tried so far ; ●Updating BIOS ●Downgrading BIOS ●Factory Defaults in BIOS ●Clearing CMOS for x hours ●Jumping CMOS ●Firmware update (not BIOS) on my 3080 ●Reseated all components ●Had all components out in a test bench build with only vitals connected ●Brand new RAM (16GB Corsair Vengeance) ●Tried RAM in different configurations ●Brand new PSU (RM850X) ●Checked CPU for bent pins/paste ●Made sure no grounding issues in the case ●Cleaned PCIe slots ●Un-tightened MOBO/AIO screws incase of a mounting pressure issue ●Update Intel Chipset Drivers ●Changed BIOS to PCIe Gen 3/2/1/Auto ●ReBAR on/off ●Removed all HDDs/SSDs/M.2 ●Safe mode DDU drivers 3 times ●Windows 11/10 There's probably more stuff, but I can't remember atm. The VGA light is lit up white on my mobo, indicating an issue but what could that issue be? It's as if my motherboard has forgotten what my 3080 is... Gigabyte logo lights up & all 3 GPU fans spin I briefly remember this being a thing with 3060s/3080Ti models, but what options am I left with on a non Ti model? I've already attempted an RMA on the GPU and they've come back saying it works...which it does! Intel have given me some software checks & sent off logs to them, all which come back working perfectly. I'm struggling to understand what the issue is here, as ALL components are working in different configurations, just not mine! Any help is GREATLY appreciated right now, thank you
It seems there might be an unlisted issue between your PCB versions and the GPU. While parts are meant to work together, compatibility isn't guaranteed. You've already run enough checks—consider swapping the board or GPU. In short, it's likely a rare mismatch rather than a common problem.
It was more frequent on older systems, yet the issue persists. That’s why BIOS updates exist—someone must address problems with hardware that doesn’t match. Avoid purchasing another GPU right away; this isn’t a reliable fix for undocumented incompatibilities.
I'll switch to the mobile version, it should cost much less! Hope it works on another board... Should I reach out to MSI for a beta BIOS that might help?
Almost nothing, you'd be lucky to get a human to read the email.
It seems the issue is with how your PCIe x4 slot handles data compared to x16. The slot might not support the higher bandwidth or configuration needed for x16, causing incompatibility.
This would make a great challenge for an engineer at MSI or NVIDIA. They’d likely dedicate several hours to troubleshooting, identify the issue, and draft updated documentation or a disclaimer stating the card isn’t working.
