Hi, I'm a owner of a EVGA NVIDIA GeForce GTX 570 from the beginning on, bought it at release date:

What is the most known safe overclocking maximum for this card?
How far can I push it at least?
 
Should this be possible?
900/2050(4100)@1.05V?
 
I tried the settings of the "SC" version:
797/1950(3900)@1.00V
This seems to work, but peformance gain is too low. Just 1-2 FPS.
 
So I want to know what most users achieved at least for this card with stock cooler (air).
 
Thanks for your help!

And by the way, what is the default voltage of the "SC" version, still 1.00V?

Nice community, indeed.

The voltage on each GPU really varies according to each different one, both of my GTX 570's came with a stock voltage of 1.0v. 900MHz on a GTX 570 @ 1.05v is extremely wishful thinking, both of my cards took 1.1v to achieve 900MHz. I currently run my 570's in SLI at 890MHz @ 1.1v rock solid stable. I would start with 1.1v and a frequency that is stable at that voltage, and then slowly begin knocking the voltage down until you find the lowest stable voltage at the desired frequency.

Just OC'd my HD card to 900mhz /1800/2000mhz Running fine @ 1.076V on Furry/Tessy stress tests @ 10mins a piece (No Artifacts at all)
 
Forgot to add Temp never went over 71c (Air Cool) (75% FS)

I used to run 950/1900/2100 @ 1.1v on my 570 vanilla card from EVGA

... but I was running it later in SLI with other card that could do max 900/1800/2000 @ 1.13v (now for sale) this is what I have seen as max for benching in SLI.

for daily use I was running 822/1644/1951  in SLI for several months.

sadly this good card has been stepped up to 670, will see what I get in return ...
 
 

I'm a new owner of a 570 SC and I've been messing around with the voltage and clocks in MSI Afterburner and noticed that while using Kombustor my core clock always throttles back down to ~400Mhz, is this normal? My temps are under 70 Celsius so I should be well within the safe range. I also noticed that when I drop the voltage down to ~.950v (1.038 is stock) it doesn't throttle anymore. Any ideas?

^ it's nowhere near normal, most likely card is unstable and driver crashes forcing the 2D clocks?
 
I used to run 570 SLI and the clocks were always staying under load where I set them (up to 900/1800/2000 in SLI @ 1.1V for both cards). try a different nvidia driver, mine worked best with 296.10.

What's also strange is I don't notice any dips in game play (BF3) but I haven't been playing very long yet. I also read somewhere that msi afterburner has a function built in to automatically throttle but I don't know if there's much merrit to that. I've tried a couple different drivers and all have the same result.

have you tried running the latest EVGA Scanner X in furry mode in native resolution of monitor (full screen mode, FXAA enabled)?
 
this one worked best for me or latest Furmark.
 
OCCT GPU test DX11 never works for me (throws some app error upon start in DX11 mode).

I haven't tried that yet. I will and hopefully I'll see NO throttling. I feel like this card has a lot of potential, just need to be able to untap it....
