  1. 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!

    Rosewill power supplies... That's 67 amp combined on all 12 volt rails. You should pay attention to the 20 amp rating only. Spending that kind of money I would buy Corsair, Thermaltake or even Antec. A good 650 watt would be sufficient here. I'm not that familiar with AMD CPU's. Why is the turbo core disabled? My Intel i5 is running at 3.2GHz, memory 1333MHz, timings 9, 9, 9, 24
