GTX 570 overclocking thread - Page 39

post #381 of 2146
I don't know what to make of my situation... I can overclock to 900/2000 at 1.05v and remain error free in OCCT indefinitely. However, I still get artifacts in BC2. The artifacts I'm seeing are little white orbs that seem most prevalent in smoky/foggy areas.

My POV GTX 570
Stock runs at 0.963v

Using OCCT 1 hr full screen complexity 8 tests.

1.038v stable at 860/1980
1.05v stable at 885/2000
(I'm gaming at 875 though to be extra safe !!!)

Temps are hitting ~50'c max at 885/2000 with Accelero Xtreme Plus cooler after 1 hour of OCCT. After 1 hour of BC2 gaming its like 39-42'c.

One thing I have noticed though and wondered about is the fps counter in OCCT.

If i go over 1.05v and above then the fps counter decreases
For eg @ 1.038v and 860/1980 i get 120-138fps
At 1.05v and 880/2000 though it drops to 98fps.

I'm sure that its the power limiter, but does it mean that any test I do 1.05v and above are not valid ????

Do you get the same ind of artifacts I described, the orb like flashes of light?

I'm not sure about when exactly it occurs for me but I also noticed a decrease in the OCCT fps counter when i overclock.

Also, where did you get that accelero extreme plus?

Walmart?

if your getting less fps that means u got to pump more volts!

I live in UK, got it from Pricelover.com, £34.
The VR004 mounting kit direct from Arctic, was $5.

Nah im pretty sure its the Nvidia power limiter, more volts = less fps for me.
1.05v or above to be specific for my card.

I was wondering if it made the stress test invalid when it kicks in, as it dynamically reduces clocks/voltage to stay within specs.

It's comforting to know someone else sees this. I considered my sanity as a possible reason.

Interestingly though, I've never crashed. It will show those artifacts all day and not crash.
