MSi GTX 580 Twin Frozr II/OC

Today seems to be an overclocking day.

So I've set my sights on the GPU, mainly I want to be recording most games with Fraps at very nice framerates. (Some games I can do this, others are a bit dodgy).

So from the get-go my card is OC'd at:

Core Voltage 1025mV

Core Clock 800MHz

Shader Clock 1600MHz

Memory Clock 2048MHz

Idle Temperatures 28-30 deg.C

Drivers: 275.33

BIOS: 70.10.20.00.01

Peformance atm:

3dMark Vantage: 23069 @ "Performance" Preset

3dMark 11: P6117, 6327 for the Graphics Score @ Default Settings

Should I just go for the max without adjusting the Core Voltage?

What kind of ballpark figures should I be aiming at?

Thanks

Have it running at the following settings atm:

Core Voltage 1025mV

Core Clock 900MHz

Shader Clock 1800MHz

Memory Clock 2100MHz

Max Temp: 57deg C (having run MSI Kombustor/KMark Extreme

shoot 4 da moon bro but be careful ya dont BOOM it

Well I'm not going to raise the Voltages, surely it shouldn't fail otherwise?

Quick update (now running OCCT to check):

Core 900

Shader 1800

Memory 2250 (4500 effective)

Max temp reached during a 10minute run (the longer test I'll do later): 60 deg C

0 errors (i.e. artifacts)

From the OCCT thing, the FPS is hgiher, both average and max, from before memory OC (from 2100MHz) the max was 250fps, from after memory OC (at 2250) the max is 380.

Running games is a different matter, crashed in Crysis2 Benchmark at both 2100/2250MHz Memory clocks.

Alright, because I want to game this evening, I've left settings at the following:

Core 850MHz

Shader 1700MHz

Memory 2100MHz

Anything above these settings makes Crysis2 want to crash

I suppose a little voltage might help, but then that defeats the purpose of squeezing the maximum performance from the card at default volts.

Updated: Now stable at 1.1V:

900MHz core

1800MHz shader

4400MHz memory

I'll check other things, but here is the Mafia II improvement:

To this:

I'll post the rest in my Project Log.

In general gameplay, from 80fps-ish, I've got about 110fps-ish.
