Powercolor HD 7850 1024 MB BIOS ROM FAILED ?

[choice]

Hey guys.

Last night i tried to flash my GPU ROM. It was successed, i guess, then i restarted the pc and only black screen. I had the backup from GPU-Z so i flashed backup again. Just look at this screenshots. I didnt do anything wrong . What is the problem? Any idea ?

Reset your monitor, if you have any overclocking utilities, reset those to defaults, also remove your gpu driver using Display Driver Uninstaller, update your chipset drivers if available, then install new gpu driver...

I dont have any overclocking ultilites. And windows doesnt recognize my GPU. What do you mean reset your monitor ? I removed GPU driver nothing changed. @eidairaman1

I tried my GPU with another monitor. Same results. I think its not about driver. Those artifacts even in my bios screen.

So if the system doesnt recognize the card you wouldnt get a bios splash screen

What should i do man ? I already did those things. When i was getting backup from GPU-Z UEFI option ticked ? Maybe because of this ? And i dont have onboard VGA i flashed backup on my friends PC . Dont know if relevant.

You can't "untick" the UEFI box in GPU-Z. Because it's not an option. It indicates the vBIOS is UEFI compatible(or incompatible if the box is empty). So no. It's not that.

I don't know what the deal is. But if flashing the original BIOS didn't fix it, you're probably screwed. The BIOS you tried could have overvolted something(memory?), and damaged it beyond repair.

I downloaded it from video BIOS collection and it wasnt unverified one. I didnt try install GPU drivers. Should i ? I just remove driver with DDU.

With this artifacts i thought it beyond driver or repair like u said.

Take pictures of the cards white stickers on the back, also you might need to take cooler off to verify what Vram you have

I had to reference a Russian site for this http://www.sotmarket.ru/product/powercolor-radeon-hd-7850-ax7850-1gbd5-dhe-pci-e-3-0.html

So You are saying I should buy new one ? XD

 

[eidairaman1]

H5GQ1H24BFA T2C 234A

Are you sure that Vram says H5GQ1H24BFA and not H5GQ1H24BFR?

So You are saying I should buy new one ? XD

No, its just a rare card now

This Bios has Hynix Ram of H5GQ1H24BFR

Id try the last 1 myself.

Make sure to clean the gpu die and heatsink off and re-apply thermal compound to the gpu die

By the way my signature has links for ati/amd gpu flashing, you can refer to these videos too

Thanks for your effort man... I will try those tomorrow on another pc cuz i dont have onboard VGA or second PCI-E slot. Even my original backup didnt solve this so ... I guess i will throw away this card. Thanks again.

Yeah several months ago i stop using my DVI port. It shows brighter everything. Maybe because of converter. But i am sure HDMI was totally fine.
