Afterburner Cashing my system

[Phoenixdancer]

hey all.

Crasy problem i have never had before has landed on me...

I replaced my 5850 with a 5870 as i wanted all 3 GPU's to be 5870 chips.

BUT, My 5970 can do 1050/1315 before it craps out in afterburner ... the 5850 could do 1175/1380..

but the max the 5870 will go to is 900 /1300...

I tryed unlocking the overclocking thing in afterburner config, this allowed me to raise the clock bar but as soon as i press apply on anything over 900 mhz on the 5870 core the PC locks up and i get a 9c or 101 BSOD....

My rig is 100% stable, i have done a 24hour prime test and 20 memtest runs all perfect so the BSOD is caused by the 5870.

is there any way to change this? i would very much like to get the 5870 to 1050mhz on the core.

Its the XFX XXX edition stock is 875/1300 acording to CCC.

Do i need to flash the BIOS on the Card or something?

please help guys.

just read the flashing guide.

I need to know how to flash the 5870 when its in the system with my 5970.

Unplugging it just to flash it is NOT an option.

Would i have to do this: atiflash -f -p 1 xxxx.rom for second card

I ask because windows see my setup as 3 cards.

and im unsure what i would have to do to pick the 5870... as its in slot 2 would i simply do: atiflash -f -p 1 xxxx.rom for second card
