Also all numbers from 01-19 is stable for me but 20 make my computer freeze.

I ran with my window open. It's winter here in sweden thumb.gif

1300mV slider in afterburner + 06 Offset voltage got me close to 1.35v. Fully stable no artifacts no freezes.

But only my first card get the boost in offset still. frown.gif

you also want to add the command lines to ALL the Ven_10 files. you should have one text file per card.

Allright
So the command should look like this?

First card
/sg0,Wi3,20,DD,06
Second card
/sg1,Wi3,20,DD,06

Alright Thanks now it works fine on both cards. thumb.gif

I haven't got the slightest clue. Sorry.

EDIT: I probably will go bigger once I water cool though. My cards are mostly limited by heat at the moment.

Glad it works thumb.gif

So you can use voltage without any issues? Thats good to hear.

Would you mind posting that block of numbers in the cfg you edited earlier?

offset numbers.

Thanks

Yes i have no real issues due to voltage. It seams not affecting stability at all going as high as 1.35v.
But i'm on 2 Reference cards so they get extremely hot. I will try overclocking further when i get my loop together.
My computer is right to a window and it's winter here in sweden so.

At 1226Mhz Heaven crashed, don't know if its the temps or the lack of Vcore that's causing the crash.
Also Using Offset to gain extra Vcore seams to be a little unsteady. The voltage goes up and down very randomly.

It's not like when you pin voltage the "normal way" it stays at that number no matter what.

Fluctuation is normal,even without offset voltage will fluctuate due to oscillation.

Forced 1.3 volts will vary from 1.325 > 1.319

High temperatures will cause instability, are you not on water?

No not yet. My rads and blocks come next week. So my testing where only about 3 min at a time with case and window open. Ambient temperature went from 20c to 5c in 10 minutes i my room hehe! Cold as ****! tongue.gif

This is my current rig with some MS paint skills over them.
This is my loop and i will be using Akrylic tubing. I hoping to finish the build in 3 weeks.

I can't verify any success with greater voltages using offsets. Has anyone using the voltage offset method gained any overclocking headroom (stable)? I can't believe a card that will stay stable at 1385 (some artifacting in TR/Heaven) at 1.212v wouldn't have any voltage headroom, but I can't say it isn't possible either. The current solution behaves exactly the same as the "broken" AB implementation.

I can solder a pot on to verify this, but I would rather not go to that extent just yet if there is a viable software control solution.
