dxgi_error_device_removed problem

[Cryo Kaiser]

Hi i keep getting the error dxgi_error_device_removed. I am very new to overclocking and using the new Crysis 3 beta to stress my Asus gtx 660ti. It keeps it running at full load most of the time with max settings and i can get about 10 or more minutes in before yellow boxes and stuff comes up and only crashes the game giving me this error. I have looked around and i might have an unstable overclock but im not to sure because i watched a youtube video with someone with a similar card and he has much higher overclocks then me and its fine for him. I had higher clocks at one point and it was fine but then i updated my drivers to beta drivers for Crysis 3. Could the drivers be the possible problem to? Im going to try to downgrade my drivers and see if that helps. Also my card nevers gets hotter then about 65 degrees and thats not that hot from what i heard. Ill edit if it fixes things. Thanks!

My rig:

i5-3570k (stock)

Antec 620 cooler

Asus P8Z77-V

Asus 660ti (overclocks as of now are Memory clock: +500mhz and Core clock: +20mhz)

OCZ 850w

Asus Xonar DGX

Wd 1tb black

Samsung 820 128gb

You're pushing it too hard on the memory imo. I run +475 memory on my 680s and thats only for benchmarking. When i go 500+, it goes unstable and crashes.

Oh ok thanks. Any recommendations on core clock? Like how far I shouldn't pass it? I did run it a 450 mhz and it didnt seem to bad. I also made a fan curve and that's helping keep temps down but 10 degrees surprisingly. I just ran like 550 mhz and it did last me a lot long then 10 mins haha.

I don't know about 660s. You could probably push the core higher than +20.

Ok. Thanks for the help!
