drums101 :
your best bet is to OC in the BIOS to me it just seems silly to use a program...here is two different overclocking guides for your type of cpu hope they help

edit: the second one is better
get familiar with the basics and if you have any specific questions after trying to figure it out let us know
click first link and read it... came back, about to click second link... see "the second one is better"
trhows first to the air and curse, proceed to read
aaaaand to make this slightly less useless:
i timed some tasks with my stock and overclocked i5-3570k:
- converting a movie trailer (0:2:02). this uses all 4 cores.
from
Codec: H264 - MPEG-4 AVC (part 10) (avc1)
Resolution: 1920x816
Frame rate: 23.976023
Codec: MPEG AAC Audio (mp4a)
Sample rate: 48000 Hz
-to:
Codec: H264 - MPEG-4 AVC (part 10) (avc1)
Resolution: 960x408
Frame rate: 23.976023
Codec: MPEG AAC Audio (mp4a)
Sample rate: 44100 Hz
- compiling freecad for 5min30sec. this uses only one core.
(I know the usual test is to time the full compile, but that crap takes hours, so i just stop there and see the progress
- no games
games are for children... and people that can spend money on a video card. not my case
also i get bored easy, so i'm browsing while i do those tests.
===
stock: (34x, with stock intel turbo enabled --raise multiplier when only one core is being used)
- movie conv: took me exactly 37sec.
- compiling freecad: 25%
avr temp: 30C
===
overcloked as: 40x on one and two cores, 37x on 3 cores, 36x on all 4 cores used.
no voltage changes whatsoever (in fact, i removed the voltage settings from AUTO to fixed stock specs)
- movie: same 37sec (4 cores were used, and linux CPU governor decided to leave them all at 1.6Ghz)
- compiling: 27%
avr temp: 33C
===
same as above, but with the cpu governor changed from "ondemand" to "performance"... basically "always full freq. linux was being too damn conservative.
- movie: 34sec
avr temp: 29C
(i explain the higher freq and lower temp because i set fan speed to 'silent' so it was spinning faster this time? no idea...)
- compiling: 30%!
avr temp: 40C on the used core, 32C all others.
===
overclocked as full time 42x:
- movie: 39sec with cpu on demand, 25sec with cpu always max.
avr temp: 30C
-compiling: 31%
avr temp: 32C on two cores, 29C on the other two.
===
and i have no idea what to make of those values
make no sense at all. maybe i need more rigor.
