clearly written on the pcb itself near the pci connectors.

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.

mmm dont know i bought it 6 months ago, its a ghz edition with VRM sensor.... i think is a second revision

Then it's a rev 1.0 card.

rev 1.0




rev 2.0



to summerize again.

rev 1.0 = No VRM heatsink , has VRM temp sensor, 6+6 pin connectors.

rev 2.0 = Has VRM heatsink , no VRM temp sensor, 8+6 pin connectors, locked voltage @1.25v .

So i've just overclocked my Gigabyte HD7950 Rev 2, locked voltage @1.25v Bios FX1 (came with it when i bought it). Ran Kombustor for 15 minutes with no artifacts.

Can i go any higher?

If anyone wants to learn how to do this, just take hex workshop or any other editor, and look at the differences.

Worked a treat - thanks robnitro! Now running 1000/1250/1.08v happily smile.gif

When I try to check my gpu Bios it just says "xxx-xxx-xxx" , doesn't say FX1 or FY1, is that normal ?

Greetings everyone!! I'm new to this forum and i love it so far, you are all doing a great job helping others.
I have a pending problem for which i don't have a clue on how to solve so i will be asking for some help.
I have a gigabyte 7950 rev.2 w/boost, my high 3d clocks are 1000/1250 1.25v which as you already know is too much because my card on load goes sky high above 80c, sometimes even above mid 80s but it throttles even on low load, regardless of power tune slider on AB. That been said, my card barely ever sees 1000mhz on load even if i try to OC it at 1100,1150 even 1200 which is very frustrating. Now i've tried robnitro's FX1/FY1 mods but with no avail, it boots but whenever i try playing a game it crashes at stock core 1000, 1,056v-both bioses. I have little to none knowledge on reverse engineering and mediocre knowledge on hex editing but when i tried editing my bios it had no positive outcome. Almost ten days have passed since i started resolving my problem and i'm on the verge of commiting suicide because my card won't budge regardless of whatever i throw at her and i'm completely stuck. So i use this opportunity to beg someone to help me mod or point me to a right direction to an offset that i need to change to mod my bios, i would greatly appreciate it. The clocks i'm aiming at are core1000/mem1250@1.150v. I will attach the bios if anyone wishes to help me. Thank you in advance and sorry for the long read.


EDIT-- I forgot so say, ASIC for my card is 66,4%

The bios you posted was an FX1, you should be able to lock the voltage to 1.150 volts with Sapphire Trixx 4.6.0 and robnitro's modified FX1 bios.

However, breaking 80c under load with original bios points to a bad ventilated case, or it's very hot in your room.

Seems like I haven't elaborated enough... Even if i lock voltage in Trixx, the card still throttles, barely ever breaks the 900mhz mark, needless to say that it almost never goes to 1000mhz. Case is ventilated enough but the room temp is 26-28c. When i benched it with robnitro's FX1 moded bios, i had to downclock it all the way to 900mhz to solve the crashing issue and in FurMark at 15 min burn in test, it never broke the 65c mark, even in a loop.
