***The Official NVIDIA GeForce GTX 570 Overclocking Thread***

[easyrider]

I ran those clocks on stock vcore and got lower scores.Its the rem error checking loosing you FPS

I upped it to 1050 and it increased

 

[mrmimz]

I downloaded the latest beta of afterburner that allows my card voltage control and upped to 1050mV, but the framerate on heaven now seems to be locking at 30 and 60 only changing to go between one or the other.

strange? or normal?

EDIT: checked my nvidia control panel settings and vsync was forced on, not sure if that really matters, however, i turned it off and the frame changes went back to normal, with the core voltage upped I managed to get a better score at the same clock of

core voltage - 1050
core clock - 850
shader clock - 1700
mem clock - 1900

temps reached max 64

Thats the error checking on the ram even though you saw no anomalies.

Are you all running the heaven bench once? Ideally you need to loop it at least twice, one run produces very low minimum fps due to loading etc.

tbid what speeds was you running the pair at ??

Im waiting on my other EVGA GTX 570 HD SC to arrive, then ill be having some more benchies

 

[Tbid]

core voltage - 1.1v
core clock - 950MHz
shader clock - 1899MHz
mem clock - 2200MHz

I'll try and get the clocks a bit higher If I can.

WOW awesome clocks. I take it you are on water with clocks like that ??

Nope I'm running them on air, I've yet to find a good fan speed to keep cool and not too noisy but with 100% fan on both cards neither of them go over 60!!

 

[easyrider]

I have left my fan on auto and have a 120mm Gentle typhoon at 7v hovered above it

 

[setter]

Stick the fan behind it easy, i found this to really help with my 470's.

Not pretty, but certainly effective.

 

[Tbid]

I will do that at some point, I'll need to figure out how as my cards take up a lot of room in the case.

I was thinking of switching the 1x230mm fan on the side to 4x120mm fans to try and blow colder air onto them, Don't really know how much of an improvement it may be though.

You guys wanting more voltage flash your 570 gtx with the asus card bios u then can take it up to 1.2 v

 

[Tbid]

Is it safe to run at 1.2v?

 

[hlennie]

I have but then im under water so guess u will have to monitor your temps closer as u go up in the voltage and the flashing was using the stock asus 570 gtx cards bios

A few people have blowed there GTX 570's by running them at 1.2v

[easyrider]

On air I wouldn't go above 1.1

 

[Tbid]

I'll stick to Vmax of 1.1v then. Really want to get 1Ghz outta these cards

What case have you got? I'm guessing a HAF 932 or HAF X?
Is the 230mm fan not moving enough air to keep them cool?

 

[Tbid]

The HAF 932 advanced.

At idle the temps are currently 33 and 39.

I just though if I replaced the fan with 4 smaller ones there'd be more airflow and I'd get lower temps, They're not bad at the moment but it'd be nicer to have lower ones as my room gets a bit toasty at times.
