OC Question

post #1 of 11
Thread Starter 
hi,

I bought this one graphics card which is available in 3 different versions.

Normal 830 mhz, OC 850 and Super OC 900mhz.

Now the question is, can I OC the normal to 900 mhz or even more? Because they are all the same cards but then I read somewhere that you only should oc max +50 mhz.

thanks guys

it depends on the thermal properties of the card. try and overclock while watching the temperatures. you will have to raise voltage as well, but too much and you can fry it. i have 2 gtx 470s that i will be OCing to 800/850 and they are only 600ish stock. if you search the graphics card forum for overclocking you should find some good answers

The actual card in question would really let us help you better. But, since I like a challenge I'm going to attempt to divine the GPU you are talking about...



Yes it is very likely that you can OC that 560ti to 900Mhz without issue. How'd I do?
Wherever you read only to OC a max of 50Mhz was either written a long time ago, was aimed at extremely newbie overclockers, or both.

Do let us know what the actual card in question is though for more accurate answers.

What the... how do you know that I was talking bout the 560 ti x_X

It' the Asus Gtx 560 Ti.

Normal Card @ 822 mhZ I think that's the stock edition..?

Slight OC @ 830 mhZ

Super OC @ 900 mhZ

To OC it you will just need the latest beta of MSI AB, Unigine Heaven and your most stressful games for stability testing.

Start out will all settings in MSI AB at default, then go to settings, the first page "general tab", and check both "unlock voltage monitoring" and "unlock voltage adjustment". Then just start working your way up incrementally on your core speed by 10Mhz at a time and run Unigine Heaven for about 15 minutes in between each incremental increase. When you start to see signs of instability then increase your core voltage by 12mV and resume testing, repeating voltage and core speed increases as needed. The most common sign of instability I've come across in Unigine Heaven are rays of colored light, but any other signs like the program or driver crashing or your clocks falling down to 405Mhz under load would also be a sign of instability as well, which would require a voltage increase. Once you are fairly confident in stability in Unigine then let it run for about 45 minutes as a more rigorous test, then finally just play your games as normal but keep a watchful eye for signs of instability for a while. For a speed of 900Mhz you won't run into too much difficulty and certainly won't get close to a dangerous voltage, but once you get 900Mhz if you want to go higher still then post back here and we can go from there.

Haha, Juano covered pretty much all the bases. The only other thing to consider is whether Asus bins their cards or not.

I don't have experience with Asus cards personally, but some companies like eVGA and MSI do bin their higher end models, meaning you'll be more likely to get an even higher OC out of an "SOC" or "Lightning/Hawk" card than a standard edition.

Either way though, 900MHz core on a 560 Ti is very easily doable on most cards. I've owned 4, and all could hit at least 900 without even adjusting the stock voltage.

so i tried oc my gpu. stock value for core clock was 830 and i tried 845 and got blue screen lmao!

i should also mention that the core clock bar was linked with the shader memory, so it moved up every time i moved the core clock. should i unlink them or is it just that i cant oc ma card

thx

You can't unlink the core clock and shader clock on Fermi cards.

As for your OCing, it sounds like you got a bit of a dud. What's your card's default VID?

You can try upping the voltage a bit and see if that gets you further, but most 560s can do much more than that on stock voltage.
