Hi guys need some help. I just built new system and trying to overclock it.
i7 930 D0, asus P6TD Deluxe, Ripjaws 4GB 1600MHz, Radeon 5870, Corsair HX850 PSU. Overclocked CPU to 4.004 GHz with these voltages:
CPU 1.33V
CPU PLL 1.90V
QPI DRAM 1.33V
DRAM 1.60V
CPU is watercooled and gets to 65-70 loaded. Tested on Prime 95 for few hours and getting no errors at all. But when I start 3Dmark Vantage it crashes after first GPU test. And it doesn't crash to desktop or gives any error, the screen just gets messed up with artifacts. I didn't overclock VGA yet, so it runs on standart frequencies, and it worked fine before OC'ing CPU.
Could you give me any advice to sort this problem without lowering CPU frequency? Maybe it's PCIex voltages needs to adjust (if that's possible)?
Any help welcome.
