PC that i used : proc: Intel Core 2 Quad Q6600 MB: Gigabyte GA-P35-DQ6 mem: Team Xtreem DDR2 1200MHz CL 5-5-5-15 2 GB GPU: XFX GeForce 8800 GTS cooling: Thermaltake Bigwater 760i PSU: silverstone olympia 1000 For Proc : Q6600 FSB = 1066. Real clock = 266Mhz x 9 ( multiplier ) = 2.4Ghz if you want a 3Ghz proc. speed, just raise FSB value to 333Mhz. NOT raise FSB value extremely.. or your proc. will blow up.. raise it continously.. ( 5mhz/10Mhz ) if your motherboard can change multiplier value, you can raise multiplier to get a faster speed too. If Computer can't boot normally. try to raise voltase value.. still can't boot, set peripheral volatage to standard. For memory : Just try change timing value to lower. can't work, raise volatge continously. Some useful tools : Rivatuner
