I tried overclocking my E8200 (2.66Ghz stock) on Asus p5g41t-m LX mobo and reached about 3.2Ghz with stability. But, that was on the expense of very high PCI-express frequency. I left it on auto in the BIOS setup. Default fsb (stock) is 333. After overclocking to 3.2Ghz, I checked the PCI-e frequency using some sort of software on Windows and using some formulas available on net. i came out to approx 132 which is very high and dangerous for SATA hard drives. So, my question is that how can I overclock my CPU to that level without increasing my PCI-e frequency i.e. I want to set PCI-e frequency to 100 manually. Are there any ways like increasing south bridge voltage or other voltages that would help in overclocking my CPU as when I set PCI-e frequency to 100 manually, it does not allows me to go more 343 fsb. On setting to a higher than this doesn't lets me boot. Thank you for any help.
