My CPU has been overclock to 3200mhz but is running on such a low v core.

[JMRoe]

I found another E5200 overclocked 3.5GHZ with a vcore of 1.14!!!! how about that hey ive been beaten, gonna attempt to O'C this weekend n c if i can push 3.7GHZ with a vcore of 1.2750 Ell post my results.

1 other problem i have is that i can O'C my RAM to 1033 (from800) with auto volt stable, but as soon as i set the volt to manual n set the factory set volts to 1.9 it blue screens
The ram i have is more than capable of archiving 1033 with 1.9v, is ent it?????
And if not is it safe to go over the factory set vcore by lets say no more than 0.3v?
oh yeah the ram is Corsair xcms6400 800mhz DD2.

Reminds me of my beloved 6420

This chip can do 3.2Ghz undervolted to 1.28v, and it's my mobo that stops it. My p5n-e SLI resfuses to go anywhere above 400, even 401 locks on POST.

Temps rarely go above 55c using an arctic freezer 7.

I'm gonna miss her when I upgrade to an i7

Ive just started OCing my E5200, its taken me ages to build up the courage to play with BIOS!!!

Ive increased the FSB to 220 so far with a multiplier of x12.5 so 2.75GHZ at the minute.

What else do i need to change as i go further???

Cheers

Hi,as you have overclocked to 2.75Ghz you get the idea of overclocking.
But to get a higher stable overclock you need to do the following:

First you need to set pci out to 100.
As you have already achieved 2.7, with a FBS 220 on auto vcore.
I would go up in 10s up in tell you reach about 256 (3.2ghz)(allowing the system to save new settings and reboot back into the bios) Now it starts to get complicated as long as the computer starts and gets you into the bios carry onto the next instruction.

Setting the vcore, well according to intels website the stock voltage is 1.2v This is enough to power the e5200 at 3.2ghz. So if ya mobo allows you to set the vcore set it to manual and then 1.2v.

Now hit F10 and enter the Operating system, download Prime95 set it all up and now stress test the system for 4hrs if all gos well then go bk into the bios and go further lets say no further then 280 with a multiplier 12.5 vcore of 1.280 giving you 3.5Ghz (dont ever go past this mark on stock cooler).
Repeat above steps to make sure the system is stable.

You can also increase the DRAM frequency easy by setting dram to manual and lets say you are using 800mhz with the e5200 and as long if the ram is good quality you could get the frequency to 950mhz if not higher just make sure you set volts to manual and set it to what ever the stock voltage is!

Its a long and patient matter that needs you to stick at it tell you get it 100% right cause you dont want to be playing crysis and all of a sudden BLUE screen!!!!!!!

Just make shore the must important and most damaging element to overclocking is Vcore never set above 1.34v instant puff of smoke n a high possibility of melting your mobo.

Good luck n hope this helps you as this info took me 3 days to learn.

Firstly, thanks for your reply RMRoe

Now the questions,

where do i find my pci out? Is it the pci frequency? If so this goes up to 99

Do i need to change the fbs multiplier?

Do i need to boot into windows after every change in BIOS?

As for cpu cooler, ive got a Hydro Corsair H50, ive never had temps of more than 52c running a torture test with Prime95 for half an hour

To get to vcore i need to enable case open right? thats the only way it'll let my change it

DRAM is 800mhz and is running at 920mhz currently

Ive read through the beginner guide to overclocking laods of times, i think i get the concept of it, its just finding out the different names for everything if you get me.

Thanks for your help, this could take a few hours
