Hello. I have a EVGA GTX 570 regular 1.2GB. It is not factory over clocked. It has a default voltage of 1.0 Volts. This is a replacement card, the one before this had a default voltage of 1.013 V. Is the lower default voltage a good thing ???? I wish to over clock safely to the Classified specs. (822 / 1951) What voltage should I use ??? Just a note, my case is FT02B with EXELLENT cooling. Idle temps, stock fan control, 25C. My i7 920 idles at 28C.

Well i suggest you to try step by step...
bump the voltage up to 1.050 and start climb with GPU core by step of 5by5 and tests...
if you want run your card as the Classy i can tell you that mine its @1.075 on stock and my 570SC run perfectly at exactly same speed@same voltage...
and about the voltage i presume that it's not better or not...its just different as the overclokkability of each cards...

To give you an idea, my 570's are completely stable at 837 with 1.075v.
Any higher core overclock requires more GPU voltage
However, I just started running them at 847 with 1.088v in BF3.

Ok so I tested it with OCCT / heaven benchmark / EVGA OC Scanner.
It seems to be stable with 1.038 V at 822 / 1951.
Temps are great.
Think I should push it higher ?

if you want to see the real limits, push the vcore to the highest setting (1.1v) that it's still safe, and bench while climbing up!!
then choose a mid-setting to use all day...

Hmm BF3 crashed once.
I bumped the voltage a bit.
Think I am going to keep it at 822 1951 1.050V

yeah it's quite a good choice...
the benefits to overclock more start to be barely noticeable...
And mind that BF3 it's very GPU's intensive, so it's more sensible to stability of OC!

I checked my MSI AB settings, can actually run@ 841 with 1.075v.
But 822@ 1.050v is a good overclock and should handle BF3 well.

my cards are 878/1756/1900 V=1.088 but I re-timmed them too with MX3, great so far no problems at all, btw they are also 1280MB cards
