E8600 E0 Overclocks

cr!spy · 22 Oct 2008 at 22:02

Shall i start off at 1.2v?

Also does the NB need to be upped slightly?

cr!spy · 22 Oct 2008 at 22:38

Dropped the vcore to 1.2v and upped the NB by 0.5 and pc BSOD on startup.

Upped the vcore to 1.26v and starts up ok. Idle temps are 36/35

Excellent. Assume you've entered your RAM voltage manually also?

What are your load temps while priming?

cr!spy · 22 Oct 2008 at 23:49

Haven't run prime properly yet. Ran it for a quick 20min run and temps were at around 50, will have to do a proper run over the weekend when I have more time.

As for the vcore does that sound more sensible now and do you think I could probably get away with lowering the NB back down?

Haven't set the memory voltage back yet still on auto. But I was running it unlinked anyway.

How are some people getting monster clocks at like 1.0v!?!?!

Hi guys,

I've just bought a e8600, how do I go about overclocking it

?

Like it was said all of them are different mine will do 4.3 stable with everything set to auto (1.26 Vcore).

What batch number is yours?

cr!spy · 23 Oct 2008 at 10:40

Nice! Did you not change any other volts? What about your memory?

Think it was a week 22 FPO was something like QX22.....

Daveangle · 23 Oct 2008 at 10:45

nope nothing as the memory is underclocking itself so it didn't need the full volts.

I have had to manually change everything to get it to 4.5 but mine is running 500FSB so the NB/VCORE needs alittle more (1.32 vcore from recollection) and the RAM etc.

cr!spy · 23 Oct 2008 at 10:58

Hmm... i'm a bit worried as I think my board will be my big let down. May have to get an upgrade...

Anyone getting 4.5 on air?

Currently on 4.4 with a vcore of 1.35. Temps hitting around 62 load and 39 idle. Orthos small FFTs test stable for 7 hours. Currently running Prime to make sure its stable before I try 4.5. Temps are a bit high for my liking. Is 65 under load ok with these chips?

Will post some screenies soon.

I can get 4.5 on air with mine at about 1.31v,temps are about the same as yours.65 under load is fine.

I will try dropping my vcore to around 1.33 to see if that can bring down the temps and stay stable. What cooling are you using? Cheers.

Guys, I still cant get this bloody Speedstep to disable! I've disabled it in the bios and also CIE or whatever it's called and I can still see the multiplier jumping up and down in CPU-Z!

Any ideas?

Here are my bios settings with speedstep turned off:

Advanced (Tab) > CPU Configuration

CPU Ratio Setting .......... [Auto]
C1E Support ................ [Disabled]
Max CPUID Limit ............ [Disabled]
Intel Virtualization Tech .. [Disabled]
CPU TM Function ............ [Disabled]
Intel SpeedStep ............ [Disabled]
Intel C-STATE Tech ......... [Disabled]

cr!spy · 24 Oct 2008 at 10:07

Only had the following still enabled:

Execute Disable Bit
Virtualization Technology

Disabled both is that ok?

mike gunnz · 24 Oct 2008 at 10:25

Don't think either of those will affect whether your cpu idle speed or overclock. If you're not sure what it does I'd leave it on for now.

hi, I used to do the same as you, disable CPU TM Function when overclocking.

But then i was thinking why turn off the thing that will stop your chip overheating, if the pump stops for example.

so i no longer turn it off and it makes no difference to any overclock.

did we just turn it off out of habit, because so far all my tests shows it makes no difference turning it off, but a bit more peace of mind with it on.

or am i talking rubbish and that command is not the one to cause throttling in an overheating chip.
