Fixing a Bad BIOS Flash on the 4870

[NKD]

Neither.

Stock cards are dieing as well as flashed cards.

The problem is the GDDR5 as far as I can tell. No 4850's have died (without heavy mods) and they are identical other than the memory.

Clap your hands for Quimonda... more crappy ram from them!

you are right that is the only difference between the two cards, so lets see what is going on, may be there was a reason the official launch was pushed to july 8th. It might be the ram, it is all speculation unless someone sheds more light on it. so there might not have been a great quality control, because we all know that these are the first wave of the cards, the samples weren't even available until few weeks ago, heck some of the review sites even admitted recieving samples a week before june 25th launch date.

whatever it is, if it is a bad bios flash there is no reason for us to not be able to flash it back. bios might be corrupt but it is highly unlikly it damaged the card from ever being flashed again.
