Did i burn my gpu?

post #1 of 6
Thread Starter 
Hi guys, ive a problem with my desktop. I assume that its a graphic card related. I have gigabyte 660 ti n66twf2-2g model. I overlocked it yesterday. The framarates went up 5-10 fps in metro 2033 depending on the move or scene. But then fps went up to 70-80fps which is impossible with my gpu. But then the game graphic became so blurry and it looks like the monitor got electrocuted and pictures became so sandy and dotty. I tried football manager 2011 and call of duty black ops 2. They worked fine. I just played 5-10mins each. What could go wrong with my card?

Hey mate. Not sure what happened. If the card is working fine now it sounds like it has sorted itself out. I would just keep an eye on the picture for distortion and also the Temps of the card when in use and idle. Just monitor it and see how you get on.

Edit - If you want a monitoring tool grab this http://www.techpowerup.com/downloads/2265/techpowerup-gpu-z-v0-7-3/

sounds like an unstable overclock, reset the stock and try again.

What is the average temps in gaming? Also call of duty and football manager work fine, but metro 2033 is so blurry. I resetted backed to factory settings. Whats it the recommended overclocking setting for gigabyte 660 ti gv-n66twf2-2d?

Did you overclocked the memory a lot? Sounds like you oc'ed the memory way too far! On my rma'ed 670 for fun I oc'ed the memory to +1200...hehe instant rsod. That was fun...

Start small with overclocking. Start with the core clock and run heaven 4.0 for stability testing, if it passes 4 loops its more than likely stable. Watch temps too. Once you find your highest core clock, back off just a tad and start overclocking the memory. The memory is where you will get big gains! Especially in that card. You can also use evga's stability tester, although I don't really recommend it since it really draws the tdp for the card, it will tell you of artifacting even if its 1 artifact.

is it true the 600 series performs better with a higher mem clock than core clock?

i can get up to 7400+ mhz memory and it gives me a HUGE boost compared to core oc
