This is what I am doing.
Booted into DOS win 98 using my usb with atiflash and your sapper.rom within.
typed:
atiflash.exe -i
atiflash.exe -f -p 0 sapper.rom
says flash completed, need to restart. So I hit the restart on my case and I can't post.


Make sure you are using ATIflash 3.99. http://www.techpowerup.com/downloads/2166/ATIFlash_3.99.html


This is the command.

atiflash -p -f 0 sapper.rom

Ah yes, I was also using 3.99. I'll give it a try right now.

One of your your BIOS switch positions may be locked as a safety feature. Both positions on my 950mhz edition can be flashed.


Make sure you have 1 working stable bios on one switch before flashing on the other. Try both switch positions. It should work on one if not I am not sure what the problem is. Please upload your BIOS from your card to see if I can get it to work on mine. cool.gif

As he said, my switch 1 is locked to the 800 MHz BIOD on my 7950.

This is the bios as I backed it up while using atiflash.
BACKUP.zip 41k .zip file

I don't think the bios are locked since I was able to brick both of them and reflashed them back to my backup bios.

My card is also a really bad overclocker. I can't even go 1000mhz core clock on stock. Its fine on furmark but when I play games..say after 2 hrs, my screen freezes and i see stripes. Temps are also fine. around the mid 60s.

I also tried bumping it up to 1.25v and 1100core, 1300memory, froze on furmark then a magenta screen with while vertical stripes.

Here is a screenshot of everything after 30mins.


It's fine now, but I suspect it will crash after I load up a game. I will test my theory out in a bit.

Yeup. I booted up Borderlands 2 right after I closed furmark with no issue this time. Pressed continue and my computer locked up and got this screen.



I am just puzzled to why this is happening. I had a TF3 with the 7970 pcb before getting this card and it overclocked fine. I only returned it because it was coil whining pretty bad (sadly the sapphire one does too). Did I just get a somewhat dud card? I mean, I don't need to overclock at this moment as stock speeds runs fine with no crashes, but it is just nice to know I can do it down the line when needed.

*using a seasonic x-660 psu. feeding power into my card with 1 modular cable that splits into 2, 6+2 pins.

Better to have 2 cables coming off your PSU rather that one split.
From that picture your voltage looks quite low, could be a lack of power.

I would say raise the voltage to 1100 maybe, your temps are already quite high though.
I don't use furmark though (GPU torture) so not sure what kind of temps should be expected with it.

what card is it?
