There's only 3 that match your card's clocks (1000/1225) that are 7850 PCS+ (which your card is).
Your best bet is to check each of these to match your card. If that doesn't work, hope you can get an RMA but I doubt that since your card is over 3 years old.

I hate to say it, but your card is toast. If you tried all 3 of those bioses and none worked, then your card is a borked for good. Unless you can RMA it, then it's nothing more than a paperweight.

Ive got a Power Color 7850... but Im not sure if its the same revision. The PCB and the fans looks nearly exact....
Basically if I dont have to open the case and look at the back of the card to be sure Ill help as much as I can.
there are a couple things to be aware of:
1) I dont know how to dump a BIOS from a card , so you'll have to send me instructions. Its better if you send instructions/link of your preferred method anyway , then you can be sure the dump is how you want it to be
2) It all on you man
Like I said , my card is a 7850 and is cosmetically similar, but I dont want to brick your card with a mistake, so tell me what you need. To get you started here's GPU-z

I'll try them, jus use GPUZ to dump the bios i've even tried powercolor r9 270 and r7 370 ones since they just rebrands, the 370 boot up but once i load up a game crashs so i'm pretty much trying any 7850 bios at this time if i cant fix it i'll jus grab a r9 270 there is one on newegg 89 bucks right now

270x is the refreshed 7850, but slightly better. I know for a fact that the Sapphire Dual-X will do 1500 Mhz memory and 1120 Mhz Core without too much trouble.
You'll need to use Sapphire Trixx to overclock the card though, as Afterburner has no voltage control for it.
Try this BIOS too.: https://www.techpowerup.com/vgabios/122284/powercolor-hd7850-2048-120328.html

I linked him 3 different bioses from 7850's PCS+ from techpowerup and the op stated they didn't work. After flashing the card works normally upon booting, but once he puts a load on it like gaming, it goes bonkers and crashes.
If he's swapped drivers and bioses, that card is toasted for sure.

The link didn't load for me for some reason, had to follow the VGA BIOS link from the drop-down menu to get it to work
TreLim, before you remount that cooler on the GPU, take a Q-Tip and some Isopropyl alcohol and clean up the whole die area. It looks like there's some thermal paste on some of those tiny capacitors. My 6850 would freak out and artifact like crazy until I noticed some thermal paste on the tiny capacitors. I clean up the card and it ran just fine afterwards.

Sweet!Ok recleaned gpu, regreased reflashed with powercolor 7850 uefi bios and it seems to be working right again now, thanx everyone for the help
How does it hold up in games?
Guess it was a combo of BIOS issues and the thermal paste on the capacitors.
Honestly I'm not sure why they put them so close to the die. Put a bit too much thermal grease on and it screwes up.

Good to hear!
Some games are more demanding that others so it makes sense that you have to back down the clocks.
