I wasn't sure where to put this thread but what the hay. So i want to boost up my CPU and was wondering if that was even possible.

Raise Core frequency bit by bit, then when it gets unstable, raise the voltage. Watch your temps, and every time you raise the frequency, do some stress testing to test for stability. Do NOT use overclocking software - just do everything in the BIOS
Watch the temps with software right?
[QUOTE=RapistSanta;21794068]Watch the temps with software right?[/QUOTE] Yes, use something like CoreTemp or HWMonitor. Here, take a look at this, it might help [url]http://www.extremeoverclocking.com/reviews/processors/AMD_Phenom_II_X2_550_14.html[/url]
Hmmm. I must've done something wrong. I went into BIOS, Found the CPU Voltage controls and cranked it up to 1.3 V (in the link he said that 1.45V was the max he got out of his CPU) So It shuts off, but restarts properly when started, I check bios again, Voltage 1.3 V so I continue loading. Didn't get much testing done though, Went back into BIOS and changed the Multiplier setting. Cranked it up to x13. Comp failed. Had to restart and go back into BIOS, lowered down the multiplier to x10. Same thing. Back to BIOS. Changed it back to only Voltage 1.3 V. Same thing. Now im running on defaults again. Maybe Im not getting something?
If you are going to raise the multiplier, set everything to default first and then change the multiplier. [editline]04:55PM[/editline] Using the maximum multiplier doesn't cause stability issues, if everything else is unchanged.
What program could I use to check the benchmarks/difference between Clocked and unclocked? Also, so I could just raise the Voltage without raising the multiplier? That would be enough right?
Start by slowly increasing the core speed, increments of 5 or 10 is good. Don't touch the multipiler yet. When the computer becomes unstable that's when you want to increase the voltage. More voltage means more heat and we all know that heat is bad. Also, think of it like this; the CPU speed is the core speed multiplied with the multipiler, increasing the multipiler can change your total speed by up to several hundreds of MHz per step.
Hmm... I'm kinda getting lost at all the BIOS selections. All I can understand mostly is CPU voltage :P
