Hi guys, I just built a new rig today, and after a few hiccups finally got it running. I want to OC the processor so I can use my ram's full potential. System specs: AMD Phenom II x6 Thurban Black Edition 3.2 Ghz ASUS M4A87TDEVO mobo Corsair Vengeance 16GB PC 1600 (currently running at a default 1333) Nvidia Geforce 560 Ti 1GB Gfx Azza Hurricane case; 2 120mm front intake fans, 2 240mm side panel intake fans, 2 240 mm top exhaust fans, 1 120mm right side exhaust fan, and 1 120mm rear exhaust CPU heatsink: Rocketfish C1 (Made by Coolermaster, is the same as their Hyper X tower cooler) POWER: Rosewill 950X Xtreme series PSU; 67A on 12v rail Hopefully the specs can help shed light on what I may be doing wrong. After researching OC methods for this CPU/mobo combo, I configured the following to attempt to OC the CPU to 4 Ghz, and get the ram running as close to 1600 Mhz as possible: CPU ratio = 14.0 AMD Turbo Core = DISABLED CPU Bus Freq = 286 DRAM Freq = 1525 CPU Voltage = 1.450v DRAM voltage = 1.650v DRAM Timing = 8-8-8-24 I figured if this was unstable, then I could simply down tune the voltages and cpu freq until I could get a stable run. But the problem is..........NO setting beyond stock is stable. My cpu stock runs at around 17C idle - 34C full load (running Fallout 3 at max settings is the best I can do application wise). So I'm wondering if I maybe have a bad part somewhere, or if my settings are way off (entirely possible). Could anyone point me in the right direction? Thanks for any advice anyone can lend!
