Can you tell me the specifications of this bios?

What exactly are you looking at? It's 1000 mhz, 1.25v boost bios don't know mem vddc. I haven't tried it on my card, nor care to lol. I just modded the asic voltage table like the fy fx bioses I did in order to help him to see if this mod works for that version too.

There are multiple versions of the boost bios because of differing hardware it seems. The fy and fx kill hdmi on cards that come with ft0 , f43, fz.

I'm using F43 bios for a long time. I tried different bioses - even F3, but for my card(wich came with F42 bios) F43 seems to be the best choise... smile.gif I tried FX and FY bioses but my monitor is connected with HDMI so they didn't work for me... smile.gif

So i decided to use F43 bios and even with my low asic quality i can achieve some very nice clocks.

Me too... I dont understand why f3,fz,fy,fx boost bioses at the same exact electrical load/volts/clocks show much higher vrm1 temps on my board.

I verified by using infrared temp gun on backside of board by vrms.

Maybe it uses the vrms at different switching frequencies...

Don't forget about the difference of MVDDC voltages. F43 works with 1.5V and the others(except FZ) work with 1.6V.

Yeah but ram only uses around 20w max. BTW, with f43 I get 1.6 vram default???
All of the boost bioses, not just gb, have much higher vrm temps for same exact vcore/clock/amps in(12v), irrespective of ram vddc in occt torture testing.

Hello everyone, i've been following this thread for a long time since i was thinking about buying a WF 3 7950, and I did. So i wanted for have the option to oc my card to 1100 or even 1200 if I can stable it but with voltage locked it's pretty much impossible right?
With your modified Bios (robnitro) I could change the voltage of the GPU ? This whole section of messing up with voltages, flashing bios, etc is really not my area and i'm afraid of doing something wrong if I try without information.

guys you dont need update bios to unlock the voltage, you can touch it trought "force constant voltage" creating 2d/3d automatic profile and it works great

your card is a revison 1 with no vram heat sink and with vram sensor ??

if yes then your method is right but we have rev 2 with vram heatsink and no vram sensor, and the method you told doesn't work tried and tested over several months.

How do you know if it's revision 1 or 2 ? Do I need to look at the gpu or is there some software that tells me ? Cause i'm not really good at looking at gpu's, sadly.
