Story's been that my dad's always been very wary of my capabilities. He had been sure I'd be ruining my rig not only when I built it but also when I oc'd my E4300 to 3Ghz, and equally sure when I oc'd my processor (upgrade from E4300 including mobo bios flash) to E8400 and oc'ing that to 4Ghz as it is now presently. I disappointed him (lol) because my pc functions as better as ever now!) My bro's pc's got an AMD 3400+ @ stock 2.0Ghz, on 1GB DDR RAM and on an Asus mobo which is very much like an A8N-VM CSM but which had been OEM manufactured specifically for Olidata and might be somewhat different (I got the manuals and everything and even if dad doesn't procure them I'm sure that I can figure out how it works since I had a good look at it). Anyway, dad's decided to "allow me the luxury" of oc'ing bro's rig... Well anyway he bought it like 3 or 4 years ago, and prolly he thinks that if I ruin it it'd be just around time to get him a new system.... Thing is that I don't want to "FAIL"... for my reputation's sake... By 'failing' I mean that my efforts get no difference in performance. I know how to oc... adjusting ram, pci-e clocks, pci clocks, other voltages etc... but if to have his cpu using stock cooler to even 2.6Ghz might mean I get no improvements (due to it being singe core) and also since his HDD's only got like 5GB free space which I can backup and restore hopefully.... well basically dad's expecting a lot - he's expecting I get the performance I used to get from my E4300 @ 3GHz using same 8600GTS as is on bro's rig right now. I wish I can but I know that a sempron 3400+ can never ever match an E4300 @ 3Ghz... expecially on stock cooler. I can over-volt the cpu to have it run at 60 degrees load. I can even use evga precision to have his 8600 GTS run at acceptable tempratures oc'd... My question is: What cpu Ghz is expected from his processor using stock cooler?
