post #7521 of 10420
Out of curiosity, how do people downvolt the card using the curve? Do you force a specific clock/voltage bin? Would like to do it as well.

Ok, I will repaste card today with Grizzly Kryonaut. It should give me additional 4-5C. I will then test if this allows my curve to stay stable in Witcher 3. If yes then at least I will know that this is a temperature thing and I will probably decide to do water loop then.

But if it will still crash then meh... frown.gif


Still funny bacause card can do 2063 in Heaven with temps reaching 69C on stock fan curve and it does not crash and that is I think on 1.081V.

Ow well, will test more.

Just make your curve flat from the voltage you want to run, its that simple smile.gif

They all downclock at these temps according to my observation: 30c->41c->52c->60c->69c.
And there is no way to escape that exept of using water on it to keep the clocks. And yes, W3 is a hell of a game to put the card to test: while I can play BF1 easily @2000/5900@1.012 on stock FE cooler for at least an hour (didnt't try for longer though), W3 can be played at only 1924. I mean stable clocks, not jumping all around.

I started playing with lower liquid temps and higher clocks at voltages above 1.05v. I'm shunt modded and got the same normalized TDP limits in superposition @ 4k.

I'm currently running 2100 @ 1.05v with +550 mem to stay under this limit.

I confirmed the limit by lowering my mem OC to +0 and I was able to run 1.06 before hitting the normalized TDP wall.

Other benches seem to not show this. +rep on this one.

Thanks, ppl usually misunderstand the shunt mod thinking it will remove TDP entirely, which is not true. I believe this normalized TDP is measure either by a low-side sensor or the GPU itself. Shunt mod does nothing to the normalized TDP. The only way to lift it is through flashing BIOSs with higher TDP.

Press L when a particular voltage is selected to lock it. A yellow vertical line should appear:

This seems to prevent the card from downclocking when at idle, however.

I take it the "Run" function to auto-tune the voltage curve in Precision is crap?

This works for keeping your voltage from going higher, but it doesn't prevent it from going lower or down clocking does it?

Well no but when at lower voltages, there should be less of a reason (Perfcaps) to force it to downclock.

It's been so long since I've had a working, proper GPU... and thanks to an EVGA Founders Edition, I'm back. thumb.gif

Since I won't be able to instal the card until Mon/Tues, it's given me a chance to research bios flashing again! I haven't touched this since the gtx 680/770 days, but I'm assuming it still works the same. Is there any particularly juicy bios for Founders Edition cards, particularly ones with unlocked voltage? Might sound odd, but I'll actually be undervolting/downclocking my card at first until I can get my case cooling scheme properly set up.
