What I do is set all the asic states to something really low, except for the last one, so 01 02 02 02 etc... then keep ff 03 for the lowest voltage. Somehow that worked on the gigabyte bioses!
Atomfix, how did you edit the vrm's? These bioses have 00 00 for the vrm register. In stock you get a value like 97 00 for example
Try it out and let me know how it goes. If this trick works for dd, wow.. awesome!

Because if I use any other 795A-TDJC BIOS's on my XFX 7950, it will brick my card, I've tried every single BIOS on TechPowerUP, and it all seems to brick my card, unless I flash the one that came with my GPU.
If it's not the VRM Registers, it must be something else that's hard coded on the PCB??
The stock voltage was 1.030V and I was able to overvolt it to 1.130V in Trixx, and it was locked at that voltage, until today, I used a edited BIOS that Kahboom provided me (Which was the BIOS from my card) , and I'm now able to go as high as 1.225V, I can go even further though! I just need Kahboom to edit the voltages even higher, but I'm afraid that the VRM's might blow, I believe it only uses 4 or 5 power phases for the GPU.
I still need the memory voltage changed because I can't get past 1350MHz without crashing or getting any artifacts.
