[GTX 590] Flashing & Overclocking Thread - Page 43

post #421 of 721
its.85 idle (lowered it a little bit).

There are 3 power profiles; idle (even lowered a bit)
CUDA applications and such and
full power performance (this level raised to .95V)


So, to answer your question, it takes even a little less idle and uses .95V full power.

Are you on watercooling? In that case, we can squeeze some more out of that card.

It's free extra performance, so why not eh?

Oh I can guarantee my tweaks work, so you can safely flash your bios.

No watercooling. Using air with stock fan with a custom profile i set up. The max temps i could reach were 76degrees (with the .925).

Faust,

I just flashed those bios you set up for me.

GPU1 idles at .875 and maxes at .963
GPU2 is locked at .888 (no idle/load difference).

Edit: With more testing GPU1 is still .875 to .963. GPU2 does get .963 but seems late to the party (hits it briefly with 3dmark11), but 3d mark crashes shortly thereafter because i don't think it is getting enough juice to start.

Additional note: 3dmark11 does run if i downclock the card below stock. Gonna put the stock bios back on for now to see what ya think might be wrong.

Thanks

hmm, you want all the voltages bumped a little?
I'll copy my own settings, except with your max voltage that I will keep a bit lower

btw, I have the latest beta drivers. Will upload changed bios later and I will inform what I have changed.

Disable voltage control and monitor on afterburner then restart. That will solve your voltage problem
post #426 of 721
I dont use afterburner at all; EVGA precision.

Dont use software to tweak voltages, this wont work.
post #427 of 721
I dsiabled voltage unlock and reflashed and restarted. 3dmark ran at stock clock speeds with the same .875-.963 and .888-.963 voltages as seen beforehand.

Gonna bump the clocks and see how it does. Will post results.
post #428 of 721
Okay the results...

Stable up to 685 (tried 700 but failed) but I'm quite happy with 685. The max temps reached were 77/74 respectively.

Working good Faust!

I did not touch the memory clock. What have you found to be a good clock for that as we aren't touching the memory voltage.
post #429 of 721
2000 will work; try 1950 to start off with.
doesnt give a lot of gain though
post #430 of 721
if you bump voltage to about 1V you can reach 750 mhz, but I don't know
if your aircooled card will like that; 80C under load would be ok I guess.

I think there is also possibility to bump the fan speed to 100% in the bios (default 95%)
I can change that too if you like.

with 1.06V I get about 50C load ^^ --> get watercooling.
Its expensive, requires maintenance and it's inconvenient so enough reasons to
get it straight away.

Swapping a card in your pc was never such a messy wet job -I've been watercooling now for about 5 years-.

The good things:
-super silent
-more overclocking headroom
