do the pencil mod it took a total of 1 second to do -- after 20 seconds of finding and verifying the right resistor. my droop is now .02 max .01 usually

Ive got a link to the image of the resistor in my sig.

I too own a q6600 and want to get past 2.8GHz

So ill put my configs in by bios, and Ill let you guys tweak it and see what works for you. (very stable...)

Voltage settings:

Vcore: 1.43750
Ram: Auto
NB Core: 1.56
Vcore offset: Auto

FSB Settings:

FSB: 1230 MHz (307.5 x9.0 Multiplier)

Ram FSB: Default

Everest Readings:




Orthos 4 core 100% cpu load Small FFT test video comming soon (Youtube).

Vdroop down to 1.25v from 1.38v (.13v Difference) on full load.

Some? More like most. I am the one lucky bastard that got his Q6600 to 3.0GHz on the P5N-E SLI

Just wondering.. Do you have any luck getting your Q6600 past 2.7 GHz? I couldn't stabilize past 2.7..

For me getting past 2.7 was a real challange. I discovered that low Vcore settings helped stability and heat tremendously.

A lot of people have been saying the P5N-E sucks at overclocking quads, but I'm not going to just accept that. There's got to be a combination there that makes it work.

It's a ceiling. All the evidence points to the 3-phase VRM design on the P5N-e SLI lacking the guts to provide adequate amps to the CPU. Most of the newer P35/X38 boards utilize 6, 8, and even 12 phase VRMs that gives clean stable power.

The Pook had good results (+75-100MHz) getting his C2D above the 500fsb+ on this board by actively cooling the VRM MOSFET regulators. I added cooling myself, but have not yet tried to clock any higher than the 3.0GHz that I got before the mods.

Again.....Especially for G0 owners, try running a low Vcore. My VID is 1.2875, I'm stable @ 1.22V running 3.0GHz (333*9).

Can you uh.. circle where it exactly is in Paint with a Red Brush for me please? I just take a pencil and shade it right?

[Nixer]

I am interested in the pencil mod too and have searched and I cannot find a detailed description or "how to".

Thanks.

[SSJVegeta]

I wouldn't mind trying the pencil mod either. I also get terrible vdroop.

[ZionEx]

Here is what I found yall.

I may try it when I get home tonight.

[Asce]

Its marked off in yellow just under the CPU fan header. Just make sure yo udo it slowly and carefully, you dont want to overvolt it like i have done.

[Gauvenator]

I finally realized what my problem is.

Turns out I have a hole at 400 too. At first I thought it was the vdroop causing instability, because more voltage helped at 400, but I always froze eventually. But now I've lowered my fsb from 1600 to 1590 and it's stable so far. Perhaps now I should try a lower vcore since it was a hole after all....

I would try a higher FSB, but idk if my cooling can handle it. I already hit 59 under load, occaisionally 60.
