HD7950 revised with reference HD7970 PCB club - Page 71

post #701 of 847
The Sapphire Boost with the fewer power phases is voltage unlocked, well at least the 21196-00-20G, not sure about the -4L but I think they are the same card.

With that overclock I get 90-100fps in Metro LL with AA at 2x and everything else maxed including tessellation so it seems odd you are struggling with NFS Most Wanted(unless that game is way more demanding than I am aware of). Also I am on the 13.5 beta drivers atm, which seems to make my card much happier than 13.4 did.

EDIT: Use afterburner rather than trixx, trixx doesn't disable the autoclocking that boost tries to do

So can we use afterburner (instead of trixx) on sapphire cards without issues?

hi there,

I received a MSI twinfrozr 7950 on the 7970 pcb today however i am having a few problems using the atiflash utility in dos.

the device id for the gpu is 679a so i am using the HIS Bios which matches correctly.

The problem im having is i cant get the dos to point to my utility. I flashed my usb with the win98 sytems files and have the 7970.rom and atiflah in the main directory of the boot drive usb.

When i type atiflash -f -p 0 7970.rom i get bad command or filename every tme. The default ds dir is set to C;\ and my usb is E;\. i have also tried usign the command C:\>E: and still gettign the same error "bad command or filename" this is very frustrating and nothing i have tried is working t get it to run the utility.
i have even tried putting the files in a folder labled "ati" in the C: directory and usign the command C:\ati>atiflash -f -p 0 7970.rom nothing works.
tried typinng dir and it says volcum c: recognised, no label. no other volumes are recognized

I am using atiflash 3.99 and have tried older versions too.

this is my first post on here and f anybody can help me out to get this DOS command prompt working correctly it would be greatly appreciated.

My sytstem is:

i5 3570k
h100i cooling
corsair dominator platinum 16gb
msi twinfroxr 7950 on 7970 pcb
z77 asus sabertooth mob
ocz agility boot disk 120gb and 1th storage Westendigital

Thanks

Yeah, afterburner works on pretty much any brand or model of GPU.

That his 7970 bios 679a from vga archive is not a 7970 one...check the speeds/voltage. Even look at the name when dos atiflashing it.

It says tahiti pro (7950)
not Tahiti XT (7970)

I just bought a HIS IceQ 7950 Boost for $300, for my bitmining rig, and I just looked at it. One 6 pin and one 8 pin, and from photos looks identical to a 7970 PCB (Only the back however). The thermal paste is really stuck on and I can't seem to get the cooler off.

Where did you find it for that price, if you don't mind me asking?
