allow me to get the general info out of the way before asking my question.... the basic hardware of my comp: Gigabyte GA-8IEXP P4 2.40 ghz w/TT Dragon Orb (currently 1.725V @ 2.664ghz, 148FSB) 1024MB pc2700 RAM (currently 2.5V @ 296mhz) ATI Radeon 9700 Lian-Li PC82COM Antec 350W psu My first attempt at OCing yielded a 6368 PCMark2k2 with FSB upped to 144mhz. It was set to 145 in bios but displayed 144. Bios setting 146 displays 145.. but set to 147, it displays 147... confused yet?? My best pcmark score prior to that was 5930 @ everything default on my computer. Freshly formatted drive and fresh install of XP pro. After tweaking the OS, I've notice 50-150 points LOWER than my initial benchmark! ...sooo, with my 1st OC, I gained about 300 pts. I've since then managed to hit 146 FSB, keeping the voltage defaulted at 1.5V CPU.. Anything higher and Windows crashes on startup or upon loading a program. I am able to run at 148 FSB (stable so far) *crosses fingers* at 1.7V~1.725V CPU. I've noticed I can run the FSB a bit more stable when increasing the voltage to the CPU. Anyone with any experience? I think my mobo/bios/EasyTune4 is preventing me to up the CPU multiplier as it is locked at 18 but believe it could do about 20 or higher?... or am I mistaken? Any software available where I could increase the CPU multiplier as well or is Intel slapping me in the face saying I can't clock that high?
