Hello,
I've been lurking at Tom's for many years but this is my first post. Anyway, I need help determining overclock settings with my newest system. For about 20 years, I have been servicing and selling computers but have never really done much in the way of over-clocking. Now I know why - it is driving me crazy! I have done much research in the past few weeks and tried numerous suggested setting combinations but I can't seem to get anything stable above 4000Mhz. Okay - my setup: ASUS SABERTOOTH P67 (REV 3.0) LGA 1155 Motherboard / i5-2500K Sandy Bridge 3.3GHz Processor - Mfg. in Costa Rica / ASUS GTX-460 (Fermi) 768MB Graphics Adapter / Patriot Gamer-2 8GB (2 x 4GB) DDR3-1600 Memory / Thermaltake Black Widow 850W CrossFire Certified 80 PLUS BRONZE Certified Active PFC Power Supply / Antec KUHLER H2O 620 CPU Cooler / WD 300GB Velociraptor / Win7 Ultimate. The 'stable' settings I'm using now (for 4000Mhz) are as follows: Load Line Calibration=Auto, CPU Multiplier=40x, VCC=1.3100, PLL=1.9000, Internal PLL over-voltage=Enabled, Phase Control=Optimized, Memory is manually set to DDR-1600 @ 1.65 volts. All other settings are either AUTO or Default. Using these settings, my CPU Temps stay at or below 40C and the BSD's have not appeared. Incidentally, when BSD's do show up, they are usually of the PFN_LIST_CORRUPT type. Also, I have tried using the Auto-AI Overclock Tuner (worthless?) in the BIOS but it BSD's or crashes before login. I don't really want to go to anything extreme but would like to hit 4500Mhz with 100% stability. Any help or suggestions will be greatly appreciated.
Thanks in advance,
Jack C.
