hi, i notice you have DDR 800 like me. the setup bios is poor because this mobo is a low cost... try this in your bios setup : AI OVERCLOCKING : MANUAL FSB CPU : 250 / 260 for test DRAM FREQUENCY : 667 i have just put the memory voltage + 0.5v, when the fsb is at 270 and the DRAM Frequency on 667, you ram work really at 900Mhz.
Thanks for tip Now I have set fsb to 280 and DRAM freq: 667. So now Computer runs about 3.5 GHz instead of 2.5 (E5200). I also set memory (and others too) voltage higher. I'll try this for a while to see if this is stable. I also am looking temps just in case.... My system: P5KPL-AM bios rev 0518 RAM: DDR 800 (2x2G) CPU: intel dual-core E5200
