But that doesn't matter as the other two, especially FY1 works great. FX1 works as promised but it is the FY1 that put my jaw to the floor.
Basically with FY1 mod you get unlocked voltage on rev2 boards. You can crank up voltage all the way from 1.056 to 1.25, it is all just based on your card's ASIC quality and choosen speed. GPU-z this time shows correct values and with some tweaking you can get all the sweet spots you couldn't get with F43 or FX-FY1. The trick is though to use Trixx as there was no way to force AB to even read card's voltage. One of the highlights of this mod is state 2 where you set GPU to 900MHz, memmory to whatever pleases you and check this out - voltage to 1.000 volts. I didn't want to go any lower because of high risk for the GPU itself, but even though my card has low ASIC it managed to work in that mode for more than a day before I shut it down. Temperatures with this settings oscillates between 58-61 with fans set to 33%. smile.gif
BIOSes automatic fan curve stays horrible though (F43 doeas a much better job here), but it is not that important to me anyways.
One more great feature is that HDMI finally works! smile.gif

This is one superb mod and trust me, this is quite a replacement for the f43 on rev2 boards, as with this one you have complete control over your card.

robnitro, you should send FY1 mod with complete description to Gigabyte, maybe they will hire you for doing such a fine job. thumb.gif

What would you say are the major differences between FY1 and FX1? Why is FY1 so much better?

You have to try it out for yourself. It's not like it's gonna blow up your card.

IGLIG had the initiative to try out my test bioses, and that is how the voltage unlock was discovered. But, if all of us just ask what is best, we may never see something that you might see in testing!

That's why I encourage people to try it out. With the bios switch, you can go back if you don't like it and reflash a stock bios.

I've tried both but fail to see why one is more 'amazing' than the other, they're both the same to me?

@Pheonix777z

Which bios exactly are you using? And where can I get it? I'm working with one 7950 gigabyte version 1 right now so it had unlocked voltage and running f43. I have another new GB 7950 on the way but it is version 2, 6+8 pin, so I am not familiar with this version and would like to try the same BIOS you are running.

I have a new WF3 7950 (stock BIOS: FT0) card and just flashed your FY1 BIOS seeking voltage unlock.

I don't get a video output (DVI/HDMI) on the card now - I have had to switch to the backup BIOS to restore output.

Is there any way to recover the original BIOS?

EDIT: Nevermind, I booted from the backup BIOS then "live" switched in DOS and re-flashed.

Can you can tell me the process in details??? and never heard of FT0 can i see a gpu-z shot ?

Judging from the pictures, it has 2 six pin power connectors, so if i am correct, then that card is a Rev 1 card & the voltages should be unlocked, i hope this helped smile.gif

EDIT: They could just be generic reference pictures & the one you recieve could be a rev 2 card with 1 six pin & 1 eight pin connector, so please be aware of this ok!.

You will receive the revision 2, 6+8 power connector. I just ordered this exact item 4 days ago, received it 2 days ago and it us voltage locked. I unlocked voltage with robs fy1

I think there is no rev.1 cards left for sale... May be second hand... smile.gif
Rev.2 cards are voltage locked. I would not bye gigabyte 7950 rev.2. Just take a sapphire Dual-X or Vapor-X. I think they are even cheaper then WF3.
