It may well be the CPU. Not all Haswell clock well. Infact most dont. Run it where it is stable.
Managed to get stable in games that is lol and over 2 hours of aida32 bench .....
though my graphics are still flakey, i can play other games but splintercell always dx11 crashes

----------------------------------
seems graphics card related though i can play other games and no issues, played bf3 tonight for over a hour no issues.
though i gave it a try just for kicks, i enabled splintercell dx9 mode with everything maxed out and the game works no lockups or crashes, just when i enabled dx11 mode that it flakes out, could it be the game ? though not heard of anyone else with this kind of crash though i have read about loads of people having blacklist_dx11_game.exe crashes.
-----------------------------------
now did you managed to take a look at the green venom set i bought for settings to try, also i have a spot cool 100 on the memory and there ice cold ready to be primed
got this new set setup with xmp 2133 with T1 enabled and no errors in memtest86+ so need some settings to test out
cheers
