Need help OC GTX570 CU II

[eiffel2985]

I just overclock my GTX570 direct CU II to 824/3902 1.05v.
on Furmark and 3dmark11 has no problem but only in Crysis.
after 30mins of playing the game will crash and I receive an error message display driver not responding.

could it be the voltage is not enough?
I just want to fallow the settings of the EVGA GTX570 classified 822/1645/3902.

I already reach 1.07v on my video card and still I get an error message "display driver not responding".

Isn't that 2X on the memory?

got the same card and am currently at 899mhz/1798mhz/4400mhz on 1.088v

going to try for 950mhz at 1.1v

using the new asus gpu tweak instead of smart doctor
