So I've just gotten back into the PC gaming scene after a long break and I've built a custom system for the first time ever. I'm currently using an MSI GTX 760 (twin frozr 2g edition). My base GPU Clock in gaming mode is 1020 MHz and the Boost clock is 1085 MHz.

I'm completely new to OCing but I've been doing a lot of research and experimenting a little with GPU-Z and Afterburner but I'm having a few issues. Every time I try to up my GPU clock past 1090 MHz I'll run Unigine Heaven 4.0 and everything will be going fine for a few minutes but then my screen will flash and then when it recovers the GPU clock is set back to the default 1020. Any speeds blow this are fine. I'm assuming this is my driver crashing or resetting clock speeds but I thought the card would be ok as long as the temp stayed reasonable. I haven't seen my temp go past ~53 C or so when running Unigine. Is this abnormal or is my card simply not able to go past this limit?
