E4500 overclock on Gigabyte GA-G31M-ES2L

post #1 of 6
Thread Starter 
Hi all,
My first post biggrin.gif yay! haha anyway down to the point a new overclocked, and i know it's a bad setup for overclocking well a lot of people say this board is a awful overclocked, but some people have managed to successfully with it.

I have a E4500 running on the board which I'm looking to overclock can anyone help me out?? if preferably to highest OC on air?

Ive read this: http://www.howtofixcomputers.com/forums/overclocking/e4500-3-3ghz-air-99686.html

Seems interesting

my current specs are:

Corsair 500W PSU
Intel core 2 duo E4500
Board: Gigabyte GA-G31M-ES2L
Memory: 4gb cheap ram (sorry don't know make)
Cooler: Thermal Take Mini Typhoon
North bridge was running hot before so i screwed on a fan on to the cooler and this seems to be keeping it cool) run at 800RPM
2 Silent eagles 1000rpm one intake at front of case and one outtake at rear next to CPU cooler

and that's pretty much it, if anyone could help it would be good if you need more info please message, p.s. I don't mind investing in more cooling as long as sticks to air cooling smile.gif

Hope to hear you all soon!

Thank you for reading the long essay!

hi and welcome to the forum.
first of all go to the user cp tab at top of page, and along the left side you will see add system, fill in your system details here

download cpu-z and this will tell you all the details you need inc. speed of ram etc...

this is a very basic explanation of overclocking

its basic maths. your E4500 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 11 (or cpu ratio)
so 200 x 11 = 2200mhz or 2.2GHz, your stock speed

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

boot into bios
disable CIE and Speedstep as these can interfere

can you raise the fsb? yours is now 200. try rising it to 220
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 5 passes. for now,

and then at final speed you want, run for 50 passes
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 and repeat the tests.
keep doing this in 20mhz steps until windows will not boot. 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 E4500 is 1.50v

I also have a E4500 but I have a slightly different mobo.

There are so many options in bios, it gets fairly frustrating.

Is it possible to completely not OC the memory and leave it at stock while OC the CPU. I know very little about memory settings and I just would like to keep them where they are. Not sure if you can do that while upping everything else, but how do you go about setting them to their stock settings and can I leave the RAM at its stock settings and get away with it?

thanks

ive had that board over 400 FSB. with that cpu you shouldnt have any issues getting some nice high clocks.

also, fill this out. it will help alot even though your OP contains a good amount of info.

No discrete graphics?

Unless you add in a separate GPU you'll struggle to overclock far - I have that board and couldn't hit 3GHz on an e4300 (fsb 333) using the integrated graphics. With a GT 240 in there it's quite happy at that speed.

G31 ES2L is a poor overclocker, has weak power phases, a crappy NB heatsink and no heatsinks on the MOSFETs.

That said, your E4500 has a high multiple (11x) so you have a chance of getting some clocks out of it.

You'll have to find out your RAM speed and keep it at or under it's rated speed, very important!

Bump the NB voltage a notch or two, and test with OCCT at each 100MHz CPU bump. I'd start off at 250FSB (2.75GHz) which your CPU should do at default VCore. If you start failing OCCT, bump VCore in increments until it stabilizes. On that board, I'd be careful if you end up much over 1.4 VCore. You'll need to get some air on the NB and some air directly around the CPU, where those small black blocks are (MOSFETs).
