New Bios update for gigabyte HD7950 ! - Page 41

It flashed fine, the new BIOS is now 015.026.000.000.000907.

However, after the reboot and when I went into MSI AB I had no core voltage control, so I went in and ticked all the voltage settings on, restarted it and core voltage is still at 0. I went in and tried it in kernel mode instead and still no luck. I'm going to download Trixx and see if I can't access my voltage with that. GPU-Z is now reading 0.85v @ 900core/1250mem. This is supremely disappointing and I don't think I'll buy another gigabyte product if this is how they do things. I could understand bios voltage lock but now it's seeming hardware locked.

EDIT: Loaded up Sapphire Trixx, now my voltage capped at 1.090v. Somehow I'm doubtful I'll even be able to hit my older 1065/1500 stability now seeing as there's so much less voltage. I'm going to give it a run and test but I'm unbelievably disappointed right now.
0.85 is in idle - under load it's 1.09 like mine - because of the low asics you need more voltage for stock clock. You can turn on voltage in AB - go in settings and in the general tab choose the voltage control to be unlocked. Try what you can achieve now on stock and then if you wish try with more voltage.

I already tried unlocking voltage in AB, it doesn't work for some reason. Which is weird because the FZ1 bios let me access 1.25v but the F43 bios caps me at 1.09v! I did the unofficial unlock am using the latest beta version of MSI AB and I made sure to restart my computer and have all the checks for unlock voltage control, unlock voltage monitoring and force constant voltage but none of them (in either user mode or kernel mode) allow me to alter the voltage. The only thing I can think of is the F43 bios from gigabyte (I got it off their website) is somehow voltage locked at 1.09v while the FZ1 is voltage locked at 1.25v.

The strange thing is after testing, I can get 1100/1600 stable in benching, whereas my limitations with FZ1 and 1.25v was 1065/1500 (1550 caused some flickering shadows). So it does allow me to bench a little higher and I'm POSITIVE if I were able to put some more voltage through it and I'm hoping there's some way possible for this but if not, I'm only losing out on a small amount of performance and I think I'm okay with that. At least now there's a lot less voltage running through my card which makes me feel more comfortable.

Just as an aside, I have the Extend Official overclocking limits, Disable ULPS, and the unofficial overclock mode is without PowerPlay support.

I can assure you that F43 bios is not voltage locked for me... May be GB started to sell hardware voltage locked 7950s because you're not the first one who complains of this issues... Very sad...
Did you try to oc with Trixx too?

WARNING: Don't reflash under windows. Just read some pages backward - i was posted a link with full guide how to update VGA bios under DOS.
I'm with F43 bios and with more or less the same asics quality let me show you what are my core clocks:

1000MHz - 1.1V.
1050MHz - 1.156V.
1100MHz - 1.2V.
1150MHz - 1.256V.
~1200MHz - ~1.3V.
I was wondering, that voltage you just wrote is it the real one (with vdrop) or is it what you set in trixx or AB? rolleyes.gif Thx mate wink.gif

This voltage is what i set in oc utilities but my vdrop is small - about 0.01V. So it really doesn't matter... smile.gif

Trixx just displays the 1090mv voltage and the bar is full, unless there's some setting I need to do within trixx that I'm unaware of it's showing that 1.09v is as far as I can bring the slider. It's the same as with the FZ1 bios where the voltage bar was full @ 1.25v and all i could do was undervolt. At least it's not terribly underclocked, the F43 helped me to squeeze a bit more from the card with less voltage, unlike the FZ1 which had higher voltage and completely unstable past 1065 core. I learned my lesson not to buy gigabyte now!

Yes, i'm a little bit disappointed by GB myself. At least my voltage is unlocked. And i can clock but with a lot of voltage. The only thing i like with this card is its cooler - and this isn't unimportant, because i am seen very good clockers but they are not stable due to high temps. Even MSI TF3s wich are known with their high asics quality and very good clock abilities suffer from high temps...

Hey guys.

I just got two Gigabyte 7950 WF3s

The good:
-They are dead silent and cool
-Clocked at 1000/1250 they are plenty fast (the shop assured me they were the 900Mhz models, fcukers)
-Crysis 3 runs with crossfire at vsynced 60fps with very high settings. Microstutter is non existent.
-So far the single 7950 seems to be around 50% faster than my 570 which was a primary goal.

The Bad:
-Both Bioses seem to be the same. They operate at 1000/1250 with 1.15V
-I cannot overvolt it. It only goes up to 1100Mhz and it is not stable for everything at that clock.

The Ugly:
-I flashed the F2,F42,F43 Biosed and the system would not boot.

I reverted to the stock BIOS. Is there a BIOS compatible with my cards, but with higher voltage? (our friend Belkov suggested to try the FZ1, any quick links to get it?)

Thanks

PS Is there a BIOS Editor for the 7900 series in order to try to increase the voltage with it?

Is there a volt mod guide for the GF3s?

Well i downloaded it from this thread - i think you can find it here, but let me make it easier for you - i just found it somewhere in my PC:
GV-R795WF3-3GD.zip 41k .zip file

By the way are you sure that F43 doesn't work for you? It's the best bios i've ever used with my card.

Thanks man.

I do ask for a little bit more help than I should, but it's just that I have a lot of things to test and my anxiety does not allow me to do proper search for everything.

Unfortunately the FZ1 bios does not work either. Thanks though, I appreciate it.

I use the atiflash.exe -f -p 0 biosname.rom command to flash my primary card. I would guess the command is correct since the unbricking with the stock BIOS works.
