Hi guys. ^^
I accidentally flashed my Powercolor HD 4870 1GB PCS+ (specs here) with a wrong bios and I am unable to unbrick it alone. So, I decided to create an account on TPU to explain my problem and find a way to solve it.
Let's start...
Since I bought my HD 4870 (many years ago) I have issues with 2D/3D mode when I'm playing games. Last week, I found the thread below on TPU forum : The 4870 "2D Low", GPU voltage/Memory clock rate Bios Thread.
I did a backup of the original bios with GPU-z (RV770.rom), flashed my card with the 1083.bin file gave by Fastmix (atiflash -f -p 0 1083.bin) and taste my pleasure to have a black screen after reboot. :-/
Then, I went to a store, bought a low-cost pcie card and followed procedures to recover my "dead HD4870".
Nothing worked... neither wiring the pin 1 to pin 8 on Pm25LV010 chip as it is explained in this thread : Accidentally flashed my 5870 with a modified 6950 BIOS...recovery possible?
But... things are quite different for me than other "flash fail" cases :
1) When I boot with a DOS startup disk in DOS mode, my "dead HD4870" is found by atiflash -i. This is true with or without wiring the 1-8 pins on bios chip. Then, I can flash it with atiflash -f -p <adapter_num> RV770.rom (only if I remove the cable between pin 1 and 8, of course ^^)... and I did it. After reboot, windows does NOT recognize my "dead HD4870", same goes for atiwinflash and GPU-z...
2) There is some kind of "pattern" when i boot with "dead HD4870" plugged + DOS startup disk ("this is my design" as Will Graham says ^^) : I noticed that, after the GPU fan goes crazy, my HD4870 has 25 seconds "to live".
00:00 > Power on
00:18 > DOS prompt appears (atiflash can see/flash the presumed to be "dead" HD48710, it works)
00:50 > GPU fan speeds up suddenly to 100% but atiflash can still see "dead HD4870"
01:18 > atiflash -i gives me "adapter not found" ! With or without wiring the 1-8 pins, HD48710 is gone... wtf is this ? The "ninja HD4870" ! XD
Anyway, the atiflash -f -p x ... works fine while the "dead HD4870" is still "alive" and i did it several time.
When i reboot to complete vbios update, the GPU fan's still runing like Usain Bolt and vbios cannot be fully updated (i guess). My computer needs something like one minute from POST message to open Windows 7. So, as you can imagine, it's a "time trial" between me and the machine before the ninja HD4870 fades away... until now, the machine wins.
I don't know why my card is automaticly "shuting down", do you have any idea to fix this ?
Regards. Thanks in advance

I read it and decided to flash my vbios. I wasn't sure about what is a "reference video card" but I thought mine was... but it wasn't. XDEastCoasthandle said:This is for reference 4870s only. None reference video cards will not work with this bios.Fastmix said:I corrected myself..6.77A can only be achieved @ 550/200/1.083 and you cannot do that without the card flickering from 2d to 3d so I use Ati tray tool..one flicker.
The bios that I am offering it's just a little bit better that the stock..and it's an all in one..
2D @ 550/900/1.083
3D @ 750/900/1.263=same as stock
and I have also included a better fan profile that keeps the card cool and yes I have used the 105 variant that you are referring as stock2.
I hope this clarifies any missunderstanding.
I do stand behind it 100% and proudly says..that up to this date is the best Powerplay (and overall) bios available for 4870 cards.
