ATI 4870 BIOS

post #1 of 5
Thread Starter 
Hi, i overclocked my ati 4870 512 MB and flashed bios. After this i reboot PC and it wont start, i can't go in PC bios, just black screen.. PC starts when i removed ati 4870 card from PC and plugged monitor to on-board VGA.. But if i place ati card back to PC, computer not boot. How can i fix it ?

You bricked the card, by using a BIOS that wasn't compatible with it; you'll need to get the stock one (or another that's compatible) to re-flash it.
Techpowerup's VGA BIOS library should have it.

If your motherboard has 2x PCI-e slots you can use another card in the primary slot (PEG 0) and re-flash the bricked card (PEG-1).
You'll just need to specify that it's PEG 1 you're flashing when you do so.

If you only have 1x PCI-e slot, you might still be able to do something similar to that by booting off your onboard, and still specifying PEG-0.

After you have sorted that mess out, overclock with ATITrayTools in the future - so much easier. Can also underclock while on the desktop to save power and heat - these 4870s are noisy, sweaty mofos.
