Hello, I tried to Overclock my CPU from 2Ghz(2000mhz) to 2.5ghz. It's limit is 2.2 ghz (221mhz) When i put the FSB more than 221, then the PC won't start up and i have to unplug the CMOS jumber to load the default values. I tried to increase the voltage, but it dosen't seems to work. I also tried to reduce my RAM frequency to 400mhz, but it only helps me a tiny bit. The FSB can be set to 223mhz instead 221mhz (Also, i don't exactly know what to do with the Latency times etc. so i have it By SPD) Here are all my specs: CPU: View image: cpu mobo: http://postimage.org/image/3jw6j3z13/ Here is a pic of my Overclock settings: View image: IMG 20120103 233304 If you need anything else like bios settings, or anything please tell me to upload a pic . Thank you in advance!
