Ok i have a shuttle AV49PN motherboard socket 478 with a p4 proccessor which is 2.53 gigs. my proccessor is only running at 1.9 gigs because the fsb isnt set right (according to compgeeks.com's tech support) but i cant find the setting to change it. i dont know whats speed its on either. the processor is 533 mhz and i am positive it is supported by the motherboard. would it work if i clicked "load optimal settings" or best performance settings in cmos. i dont want to overclock anything. just want it to run like it should
