7950 Overclock Voltage

[Sleeve]

Those of you with 7950 clocks past 1100, what are you running your vaults at?

I've read anywhere between 1.2-1.3v but just want to be sure.

Currently on stock volts I can't get 1mhz past 1100 without a crash.

Thanks

1st 7950 -1200mhz
2nd 7950 - 1125mhz

I want to say "stock volts" as Ive not altered voltage - but realised when benching my newer 7950 that because I have the boost editions the voltage ramps itself up to the maximum recomended 1.25 volts when using the higher clocks :-/

I have pretty poor overclocking 7950's that are low asic cards so require a lot of voltage. I run 24/7 1100/1575 at 1.169v.

Ditto - my Gigabyte Windforce 7950 needs 1.14v to hold 1100/6000, though an hour of Battlefield got to 77% in the recent hot weather so I cranked it down to 1000/6000 (1.05v) to keep the temp under 70'C. Might add a second (or a 7870 LE Tahiti) at stock, if the AMD drivers work well on Crossfire at the end of the month.

1.13v on a voltage locked HD7950 running 1100/1400

i run 1200/1600 @ 1.17v /1.6v for every day use, for benching and high stress games 1300/1900 @ 1.28v/1.68v

I can run 1150/1650 at 1.3v core and 1.7 memory. But I run 1050 at stock (1.25 boost voltage). Mine is a pretty poor Overclockers too

MSI TF3 Rev 1

I have 2 MSI HD 7950 TF3 rev 2.. and they do 1125 with 1.25v, they do a little bit more with more voltage.
But I use them at [email protected]

They have really low ASIC both under 60...

benching I can go to for something around 1180/1800, gaming if it is a heavy game I use 1100/1500.
