Same card Stock

Overclocked

Temps and noise are in check, so I see no reason not to overclock.

I think this is a successful OC - correct?
Unigine, passed:

I had all 3 voltages maxed, above I was +90 core and +746 mem. That is Heaven stable, but I later found out it wasn't Crysis 2 stable after about 90 minutes. I have since backed my clocks down to +80 core and +596 memory which is perfectly stable.

Here is heaven maxed at +80 core and +596 Memory

I haven't tested it but I think you would be better off running Afterburner 2.2.3, as far as I know Nvidia made MSI get rid of voltage control in newer version of AB. I have been using 2.2.3 since I got this card. maybe sometime if I get bored I will download the newer version just to see if my card still runs at its max clocks or if indeed the voltage has been compromised

Cheers for the reply!
Well at the moment I'm aty +500 mem and +65 core.
As for voltage control, if u see my screenshot of the OC, you'll be able to see I set the power limit to the max, and the voltage limit to the max.

Also I would like to know how do you make sure the OC is stable - apart from making sure unigine completes the benchmark without crashing?
Are there any other programs, thgat will help me determine that it is stable?
And more so, how long I should run them for?

As I got kombustor, which seems to have many tests.

EDIT:
Yeah for some reason I can't get over +65 core clock with +500 mem
Core voltage is on +100
With power limit set top max @ 114%

Right so here's my results so far - Unigine doesn't crash and runs fine 3x in a row:

I think you should try Afterburner 2.2.3 and see if you can get your clocks higher biggrin.gif

Lol ok. But how does that help the card lol?
Did you check my print screen, about the voltage thing bro?

EDIT:
That caused problems - back to 2.2.5

EDIT 2:
Does the memory and aux voltage matter?
Does anyone suggest I do anything more?
Do i need to run through any more stress tests?

Would like to point out - with the 4.0 heaven the scores of the 660ti are drastically different.
See below - stock speeds (as seen above), yet radically different:

Benchmarks used on the 3rd of September 2013:
-Unigine Heaven 4.0
-Unigine Valley 1.0

Nvidia drivers used:
326.80 BETA (made no difference between the stable and BETA one - tried both)
660ti PE OC scores (Click to show)






And just to prove this isn't a glitch of my GPU - I recently bought a GTX680 - here's a screenshot of it too: 680 scores (Click to show)
