Overclocking my 660 ti

post #1 of 16
Thread Starter 
I'm a total newb at overclocking and I want to know 2 things. First, am I risking anything by doing it (other than the warranty obviously)? Could I fry it by making it too high? And second, how much can I overclock my card? I believe mine is the msi non power edition 2gd5 (single fan :S). (dont know the exact name). It doesnt have the voltage unlock, but is there a way to mod the bios or anything like that to allow it to? I probably won't do that until I get a new motherboard (running dells oem mobo on my xps 7100 right now lol) but just to know.
What are some numbers that I can try? I don't want to do it like +100mhz and then see it like crash and fry everything or something.

thanks

First look up the 670 overclocking guide here, the 660ti will functionally overclock in the same manor, then head over to the 660ti thread you can find how to update to unlocked voltage bios there, overclocking is generally harmless on a voltage locked card as when it starts to crash / artifact you just lower the clocks. A good starting place for the core is varied because some models come with a factory overclock. If you have a reference clocked model +50 core is a pretty good place to start and go up from there. Memory overclocking is where the 660 ti shines. I have benched mine with +875 mem. However I would start at +400 and again go from there. YMMV but you will also want to increase power target (I think mine is at 115%) and set Nvidia control panel power options to maximum performance.

Cheers and good luck!

Thanks man. Could you explain what the power target is? And how I can change it?
Also, once I've changed the clocks (say +50), how do you test it? Should I just fire up a game and see if it works without crashing? Should I use a benchmark like ugine or whatever? I think I've heard people say that you need to do it for 4 hours or something, is that really necessary?

Change power target in MSI Afterburner, gzyxya smile.gif
It will increase TDP of your card so while at OC clock, your card won't throttling down.
Just test it first with 3DMark Vantage, 3DMark2011 and 3DMark2013. Run each benchmark with 3xloop ... if you have anomaly visual like artifact you may try increase volt or decrease your clock, after that go on reallife apllication test which is gaming biggrin.gif Try heavy games like BF3 or Crysis3.

Do they have any free benchmark programs? The games I have to test out are crysis 2 and metro 2033 at the moment (wish I had crysis 3 haha).

You can use furmark which is free, I use it to do a quick check before testing in a game.

Using Furmark is like dropping a 100lb weight on someone's chest when they're sleeping... yes it does stress it but not really useful.

I use EVGA OC Scanner. I'd use 3dmark 11 or Heaven or some other benchmark similar to that to accomplish what you want. Just not Furmark which gives you 15-25C hotter temps than you'll ever see.

Haha nice analogy. I'll check those out. But is there like a starting point I should try it at? I feel like I'll have to mess around a lot and just wait for the benchmarks to complete while I have no idea how much I should be able to get it up to

Start with something like +50 core and +200 memory, and then work up from there. You can check stability pretty quickly, at least initially, with Heaven or Valley. If it can complete a run of those you can bump the offsets up a bit and try again. If it fails, then start backing down from there. Once you find the edge point for stability go run some BF3 or FC3 or something to really test it out.

You don't need to run the full thing. Just enough that it won't crash.

Every GO you're not going to see if it's stable.

Same principle on CPU overclocks.

Test 10 minutes at a time for a Quick 'N Dirty range limit.
Once you're unstable BACK DOWN and then start honing in and using the longer tests or begin NOT-stopping the tests after a short duration like you were doing quick'n'dirty.
