I do not want to change anything, just the boost function bypassed HEX editor to set the reference voltage to 1.125.v

I'm sorry if I phrased a bit incomprehensible, but I speak only Hungary and I used google translator

Why so low ? Im looking into the rom file now, just wanted to know, is it very hot where you live, do you have poor case cooling? Do you really need 1.125v for 925mhz and 1250mem? Thats kind of high, Have you ran test and confirmed that you need that much to run at those clocks?

925.MHz you enough for 0,975. V. also

ASIC calculated value 1.125. V.

Cooling is no problem Alpenföhn Peter 79XX Edition operates on the card smile.gif

How is the cooler performing? What fans do you have on that cooler? What sort of RPM's are you running?

Cheers

I have no idea what a Alpenfohn Peter Edition is, never heard of it. What does it look like? Sounds interesting. The bios have been set for what you have specified. Dependent on load conditions it what the ASIC table is for. Under load it will volt up to what the table states but mind you that these cards have vdroop under load. So test them and see if it works for you.

Thanks for the info. What fans do you have on the cooler? 120 or 140?
I was thinking of buying a 3rd part cooler for my HIS but not sure what to pick.
Prolimatech Black Series MK-26
Alpenföhn Peter
or
Arctic Accelero Xtreme 7970/7950
