Alright, this is a doozy. I'll try to keep it short and concise but er, no promises.
I was using an fx4300, asrock 760gm-hdv, 8gb ddr3, rx480 8gb setup but decided to upgrade and picked up:
Intel i5 10400f
Gigabyte H410m S2H
G.skill aegis 2x8gb ddr4 @3000mhz
I slapped my old parts into another pc with a 560ti and installed the new ones with my rx480.
Attempting to boot the new setup with the 480 gave me no display signal - at that point I tried to slot in an old HD 4550 into the new build and everything worked flawlessly. I then try to boot new build with the 560ti - everything works fine again. So it's not the hdmi cable, it's not the pcie slot on the new mobo.
Worried that my 480 is deceased, I plug it into the old setup with the fx4300 and... it works fine. The psus are 500 and 600w for the old and new setups respectively and both have run the 480 no questions asked, so neither of them are dead or insufficient.
I tried flashing the bios for the new motherboard to the new version - no dice. Same with fiddling with bios settings - CSM on or off, above 4g encoding, etc.
To be clear, the 480s fan does spin up with the new build (and yes lol I'm plugging in the 6pin), I just get no display with it specifically. I booted with the 4550 and used DDU to clear previous drivers, I've reset the CMOS twice now, still no display from the 480 and only the 480 in the new setup.
What's the chances my motherboard doesn't somehow support the 480? I'll be honest in saying I've never seen something like that be the case, but worth asking. Should I try booting with the 480 but with only one or the other stick of ram in there? Haven't done so thus far cuz I figure if the ram works fine and is detected with other gpus, I can't imagine it being an issue with this specific one. Will reiterate that the 480 works completely fine on the older PC, tried with both PSUs.
Seriously at a loss here, lol; I don't have another lga1200 motherboard on hand to check if it's a motherboard issue and am running out of ideas.
Cheers
