    :) Thanks, and yep I was thinking the same thing, I've actually had my eye on the Sapphire 7870 2GB GHz Edition £199

    £145 saved so far so might not be too long until I'm back up and running properly

    <<< Rest of PC specs

    Perhaps those two are enough, but Sapphire may ask you what ram chips are used (Elpida/Hynix/Samsung).

    Anyway, I overlooked what other posters have said about the possibility that your HD 6850 may have broken something because of the HD 6850-to-6870 bios flash; some of the video memory chips may be fried due to the memory voltage differences between the HD 6850 and HD 6870 cards. So you still may need to send back your HD 6850 if the bios from Sapphire does not solve the problem for you.

    As for what Qubit said about the small upside to all of this, yeah, a nice excuse to upgrade to a better videocard. I can recommend you to buy a HD 7950 because you can get 3 new games for free: Far Cry 3, Hitman: Absolution and Sleeping Dogs, and 20% off for Medal of Honor: Warfighter via the AMD "Never Settle Game Bundle" promotion (terms and conditions).

    For another £40 you can get a 7950, or another £100-£120 a 7970. I'd recommend either one of these two, as performance is quite a bit better. The 7950 is much better value though, since performance is close to a 7970, but much cheaper.

    Also, I've found nvidia to work better overall and tends to have less driver glitches, judging by forum posts, hence I recommend nvidia nowadays, if you're up for switching. :) Certainly my GTX 580 has been near flawless in the year or so that I've had it.

    Thanks for the tips :) 7950 does look tempting, might stick the 6850 on ebay as faulty and explain what I did to it, someone might want it for parts, could bring me ever closer to my new GPU

    Oh, forgot to recommend checking out the graphics card reviews here on TPU. They're all covered and you can see exactly what you're getting for your money!

    Find another computer and put the card in it. BSOD, card bad. Pretty simple.

    Yea, the cards definitely bad, I have a 5450 in the same machine atm and its working fine

    Anyway, good news, I found the extra few £ for the 7870 and all being well can pick one up tomorrow, the 6850 can sit on my desk until I remember to stick it on ebay for spares/repairs

    Thanks for all the replies everyone (except the troll) :p

    I actually survived this mistake!

    First of all sorry for the necro, but this is the first page that pops out when googling the issue and might come in handy for someone in the future. I actually was naive enough to believe this could be done (the same way it can be done from 6950 to 6970) and since I got a new GPU decided to try...

    Both of my 6850 bricked (yeah I thought: "lets flash just one and see what happens" but in the end flashed both), after reboot I could hear the windows welcome sound but there was no display on any of my screens so...

    I shutdown my PC immediately to avoid HW damage and followed this procedure:

    - download 6850 (sapphire) rom file (using a different computer).
    - save it on the usb stick used before as "6850.rom".
    - boot up with the usb stick.
    - run: "ATIFLASH -f -p 0 6850.ROM" (no quotations)
    - wait 20 seconds.
    - run: "ATIFLASH -f -p 1 6850.ROM"
    - wait 20 seconds.
    - reboot

    Both GPUS are fine, probably because I was fast enough realizing I could be breaking my cards, I hope this helps someone in the future.

    thanks for sharing. Learn from your mistake indeed :nutkick::nutkick::nutkick:

    but I dont think even you let it run long time will damage. But who knows, its better to fix right away than make the problem longer :toast:
