E5700 overclocking advice

[brianthesnail]

Hi guys
im resurrecting a socket lga775 based pc( e5700 cpu ) that's been sitting in my spare bedroom for the last 2 years .... upon first boot the pc would start and stop continuously however I discovered the psu was at fault and fitted a spare 300w antec psu... worked great
anyway ive installed windows xp media center and all the drivers,and the cpu temp is sitting nice at 22c ..... so since its not my main system I thought I would do a bit of overclocking ....
now although ive been building pc,s for around 8 years and been a enthusiast for over a decade my overclocking knowledge is pretty basic ... the last cpu I overclocked was a Celeron E3300 from 2.6ghz to 3.2ghz and that was done by simply increasing the fsb from 200mhz .... however I want to see if I can get the E5700 to at least 4ghz,and I know this is possible,however I need some advice on voltages ect
what would be the best method for achieving the best overclock... increase the fsb and then the voltage ? ...
ive already successfully hit 3.4ghz without any problems,and no voltage adjustments were needed ...
any advice on how to achieve a higher overclock ....

many thanks

I use to run my e8400 at 4ghz. I did have to bump the volts to the cpu and North bridge.

If you are not worried about damaging the PC you can be quite aggressive with the fsb and voltage adjustments. Set the fsb for 4.0 and then make sure your RAM isn't being blown away by it's OC. Give the north bridge a voltage bump and CPU a couple more and see if it'll boot.

If you want to make sure you do not damage anything you'll just need to trial and error your way small steps up to a stable 4.0. I'm sure the core 2 oc guide is still floating around in a sticky thread somewhere.

What motherboard are you using?

I was able to get over 4Ghz on my e5300 relatively easy..... on a high end board.
That same cpu gets to 3.6 tops on a low end g31 board this may be due to mix and match ram but if it is all rated at 800Mhz so it's hard to tell

Keep the frequency of the ram at what it is rated for or lower

15x265 = 4000Mhz but that has ram running pretty slow 530/533 which is fine but why not try to get it higher

12x333 =3.96/4Ghz ram at 666mhz and so on

I always liked higher bus and ram speeds though I am to understand the ram and bus speed really don't make that much difference, but I can not say for sure as I was not interested in low bus speeds and ram speeds.... why have the ability to raise something and not do it.

please don't be afraid to lower the multiplyer as yours is very high with a very low FSB which makes for excellent overclocking

I was able to get to 4Ghz with relative ease and rather low voltage, DO not exceed 1.4 on the core with that chip, it's way more than needed to hit 4Ghz unless you have a terrible motherboard.

Do all overclocking from the bios, software overclock such as setfsb is not stable.

Just humor me

set FSB to 265
set pcie @ 100
make sure the ram is set to 533 adjust the divider as required and boot it up
Just see if it boots
Nothing will be damaged
if it boots run prime 95 if it fails up the core voltage
if it runs for a couple hours great you gained 25% more clock speed
there is no need at all to adjust NB voltage unless you have a lousy motherboard(which you might)
