overclock GTX 570

help to overclock Asus gtx 570 directCU II using Asus GPU Tweak(Rog tweak), preferably exact values(GPU clock, GPU Voltage, Memory clock), but not to burn.

Hi iiya150...

As I'm sure you know all the cards are different and this makes handing out numbers useless.

When I had my 570 the core clock OCd very well and the memory hated being OCd and I've seen the opposite. Raising voltage to the maximum the stock BIOS permits wont burn your card (in all probability) so just go ahead and raise that up to max and see what you can get....

Personally I would do this with Precision X or Afterburner but....

This also depends on cooling...air or water?.....Air I would shoot for 900 or (950 maybe) on core

On water the max I ever got to with mine was 985 on core 1125 memory....

Maybe yours will be worse or better on one or the other....on memory I hardly think worse 😉

Your card will work best with Afterburner as GPU tweak was not released when it came out.

Each card is different and will need some kind of trial and error. There are two key things to pay attention too. First temp, use the GPUz sensor tab to keep an eye on the temps. And second, voltage. These two are related, the higher your clock your graphic card the hotter it will get as the core has to work more. It is very tempting to bump the voltage up as high as it can go and just clock your card. But do not do that please.


You should be looking at about 900MHz on air for the core and about 1250MHz for the memory.

Actually this is sound advice and something I missed form my post....I was kind of assuming cooling would be taken care of but should have said that.

On air the first thing to get changed in Precision X or Afterburner should be the fan profile.....I had mine ramp up straight away and by 70 degrees be on 95% as a first step....just to make sure max stock voltage could be cooled....

My 570 would only do about 900 on air...had to go to water cooling to get higher clocks stable on same max voltage. so you can see temps are limiting and critical...
