ATI Hd 7950/7970 bios mod thread - Page 6

post #51 of 1288
Hi guys has anyone tried to disable the BOOST?
I tried multiple of BIOSes and none worked on my card, bought it on 22 december 2012

My card = HIS IceQ 7950 Boost edition 925/1250 1.25v, ASIC quality 79.8%

HIS IceQ 7950 Boost edition BIOS.rar

I wrote to HIS with a question if they could provide me a non boost bios that would work with my card, still waiting for reply. But from what people say they usualy take up to 7 days, so...

Is it possible to mod the vcore on the bios? For example the default vcore on the DC2T's is 1.170, where as the default on Matrix is 1.256. I would like to set her at 1.300 as the card is voltage locked but changes fine with bios flashing.

You can mod the vcore using the vbios editor from TechPowerUp. Here is the DC2T with 1.260v vcore (it will default to 1.26v, so you will have to use GPU Tweak if you want it lower) when running stock clocks):

The thread itself has a lot of pooled knowledge:

You can easily mod your own bios using the utility though. it works with the DC2T. I now run mine at 1180/1650 with 1.219v vcore.

Thanks Kahboom thumb.gif

My XFX 7950 BIOS is listed in the first OP post, it should work on all XFX 7950 795A-TDJC without bricking your card! It unlocks voltage control right up to 1.2V, anything over it just won't be possible, it gets highly unstable.

Thanks!

I have reached my 2 days limit.
I don't run WC any more, clocks that I use to run were 1100/1500 1.150v but it seems to crash now...
I think 1000/1400 1.1v should be ok, but to make sure I will check.

EDIT

1049/1352 1.1v on the core and memory stock 1600
Fan speed auto, max temp after BF3 and then 3d mark 11 68c on IceQ cooler.

Im only one person, and i had more to edit on tech power up forums as well, working on right now, regarding your cooler you should check to see if you reseated correctly, and check thermal pads.
