Ok, I know that this CPU and its counterpart components (MOBO, RAM, etc.) are quite old and I'm overdue on upgrades. But I don't live in the UK and I don't live in a country in which I can easily upgrade in my current situation (college student on a tight budget). I got a Xeon L5430 (2,66GHz) on the G41-MT-ES2L with 8Gb Kingston 1333MHz RAM (which as far as I know runs in 1066 because of the MOBO). I got a BIOS mod that unlocked every option in the MOBO (Voltages, timings and whatnot), I'm not an OC guru or whatever I've overclocked my old C2D to over 3,20GHz (2,93GHz) on an older MOBO with G31 chipset. But I can't get this CPU on this MOBO to go over 2,73GHz (342x8) if I go over 342 it doesn't POST and reboots with default settings. I know nothing about RAM timings or anything related,but I'm guessing it has something to do with it and I'm still looking into it but I would very much appreciate any help! P.S.: It could have something to do with the PSU as well (I have a stock 250W until friday, a 600W coolermaster "masterwatt lite" as of friday). Appreciate the help!
