[un]official GTX580 Overclocking Thread

[65vette]

Hello, Try using Nvidia Inspector to bump volts and you will get an increase with AB. Just be careful using/with good cooling. I can go to at least 1.4vgpu with my 580ltng. Also multimeter is your friend.

hello

My GTX 580 Lightning

MSI Afterburner Bug

+100Mv 1.01 GPUZ

its not a bug ...its that gpuz does not read set voltage just stock vid on this card.
unlock voltage monitoring in ab settings you should have np reading & setting voltage with afterburner.

1.4v? on air?

EVGA does not return the same card to anyone on an RMA, ever. Did the card you received have the same SN? Does it have some distinguishing marking that you can use to prove it is the exact same physical card? EVGA's policy is that any card that is received is placed into a bin for testing, and one that has already been tested and repaired and tested again is sent out for RMA. Therefore, if you have experiencing the exact same problem with the replacement card, then the problem was not in the card in the first place. Have you tried contacting EVGA to see if there is anything they can do to help?

you can't be that sure, since the fact happens to me. EVGA DID TURN ME BACK THE SAME FAULTY GTX580 that i sent to them as RMA. either u believe it or not. it was the same one, the same problem, the same package! The dealer give me back the whole money, purposly kill the 580 and send it back for the second time for RMA. after that they give him a new one.

So what should I trust for reading voltages, Afterburner of GPU-Z/AIDA64? Afterburner shows .08V higher than GPU-Z.

[donmarkoni]

You should only trust DMM. (with fresh batteries)

[andressergio]

is it inspector more accurate than afterburner to increase volts ? or the same ?

[p3gaz_001]

is the just the same

[p3gaz_001]

that's default voltage and core speed?

[vern]

that's default voltage and core speed?

Default voltage is 1.075V
Core Speed is 816Core 1002Memory

[p3gaz_001]

950mhz with stock v .. is pretty GOOD! nice deal

congrats Vern told ya that 580 where killer cards

is that a skin for afterburner ?

Thanks
No , this is GPU Tweak
This is really good software
Support all card

yeah i tried but it doesn have ingame info like afterburner

[vern]

yeah i tried but it doesn have ingame info like afterburner

Yep
I hope this tool will be update

[Darknight]

hello
need an opinion here.

what is the best choice
a reference EVGA GTX580 with EK waterblock, or an Asus GTX580 DCUII

both at the same price for example.

[Hondacity]

you can resell the dcu2 alot higher

[CryptiK]

Would depend if you watercool and want the card watercooled - I could have bought a DCuII but IMO they're no better than a reference card unless you're subzero cooling and I wanted it WC so the choice was easy. By the time I resell either card would be worth perhaps $100 anyway so I could care less what the resale value is - blocks never fetch much used so once you WC a component you're kinda committed to keep it awhile. If you only keep components a short time and resale matters to you then yeah, DCuII would be the better choice.

[Darknight]

ya.
thanks
Anyway, I ended up with the evga with block
have advantages in temps and possibly in the OC.
and how I intend to do SLI, so takes up less slots and helps in temperatures later.

[CryptiK]

And it looks way better

[i_max2k2]

So after getting my vanilla evga GTX 580 a few days back, I have been trying to overclock, and with decent system airflow along with low ambient temps, I have tested upto 950/1900/4200 with voltage @ 1.15v and load temps never going over 74C. My question was what are safe 24/7 voltages running this card on its stock heatsink (I will redo the tim today or tomo), and can I go higher, cause right now I'm limited by the cards bios (I cant select any voltage over 1.15v), the above clocks are not 100% stable and I think if the voltage was a notch higher and the clocks could be 100% stable.

HTPC? Hmm... I don't know... I doesn't seem powerful enough for HD movies.

1.4v? on air?

Sorry didn't see this until today.

I have an ln2 pot attached to this card for 1.3+vc. On my Lightening, using the software NI in combo with AB, so far not very cold (-75~-90c), I run benches at 1200+ like yourself and many others I've seen here. Start at 1.36~1.38vc and 1.4vc will hit on my MM under high load.
