OCing a E5300

I want my PC to be a little faster, and was thinking of OCing from stock 2,6GHz to 3GHz, would this be possible? (As in stable)

(My PSU is unbranded, no idea of its Specs)

Motherboard: Gygabite GA-EP45-DS3P

yes as you have an excellent overclocking motherboard (one of the best ;))

i would be a bit concerned over the psu, when overclocking, its important to supply constant voltage, and most generic psu's are not good enough.

And what cooler have you got? As a stock cooler will severly limit the overclock.

there are loads of guides on the net (just google E5300 overclocking), but here is my effort.

this is a very basic explanation of overclocking

its basic maths. your E5300 is rated at 800mhz. you always divide this number by 4 so 800/4= 200, this is your FSB. (or cpu frequency)
then your processor (cpu) has a multiplier of 13 (or cpu ratio)
so 200 x 13 = 2600mhz or 2.6GHz, your stock speed

boot into bios,
manually, unlink your ram, so it stays at stock speeds, you can overclock the ram later.
this means leave it at 800mhz, 667mhz, whatever

can you raise the fsb? yours is now 200. try rising it to 220 (2.86GHz)
boot into windows
download realtemp and coretemp (google them)
install and run them
then download intel burn test (ibt) and run it.
have a look in task manager and notice how much free ram is listed.

in ibt set threads to 2 (for 2 cores) and then click on custom ram and enter an amount just below the free amount.
eg. i have 2520mb free ram. so i enter 2500 into the custom ram.
run the test for 10 passes. for now,
keep an eye on temps (do not let it go over 70.c)

or download prime95 and run the torture test/large fft's

if test runs fine, go back into bios, and change frequency (fsb) to 240 (3.1GHz) and repeat the tests.
keep increasing the FSB, by 20mhz steps until windows will not boot, or test fails.
then just go back a step (remove 20 from the fsb) to the last stable frequency,
or
just raise the cpu voltage a couple of levels. it should now boot.

its a balancing act, higher voltages will get you higher fsb, but it will also give you higher temps.
max voltage for a E5300 is 1.36v


the trick is to do this step by step, just take your time.
also some people have had more sucess shanging the cpu ratio (multi) to 12 or even 11

edit.
can you tell us
Psu make
Ram speed and amount
Cooler

PSU has nothing on it, literately. I cant know the make of it.

RAM is 4GB (2x2GB) 400Mhz Ea (800Mhz)

Stock CPU Cooler.

If I cant OC it I guess I'll just wait and get my

1.XFX 650W XXX Edition Modular '80 Plus Bronze' Power Supply
2.Gelid Tranquillo CPU Cooler

(I'm building a new High-End PC, and I'll use these parts with my current one until I have the full build)

Just waiting for Special Offers on them.

(Tell me if I should still do it)

you should defo do it :D

i would still give it a try, just raise the fsb to 220 first, then run the IBT to test for stability. (keep an eye on temps)
if it passes 10 runs, try a fsb of 230.
i would then leave it at that for now, until you get a better psu and cooler

when running IBT, personally i would not let it go higher than 60.C.
if its going higher, stop the test.

these temps are extreme, as day to day gaming, the temps will be lower, but you need IBT to test for stability
 
I just tried and it fail booted 2 times..

I Enabled it and set it to 220, and tried doing something with RAM for it to stay at 800, there is a few multipliers to select and in description it says x.xxD -> 400 MHz so I went with a random number from lowest to highest, and found that highest I could go for was 743 MHz :S, couldn't keep it at 800, so I did and it fail booted 2 times..
 
your nearly there, it doesn't have to stay at 800, as long as its 800 or lower then its fine. So 743 is good for now.

did you try raising the vcore (cpu voltage) a couple of levels?

did you download cpu-z? this will tell you all the info you need. eg. vcore, fsb, multiplier etc...
