E8600 Overclocking log

[Bungral]

Just wanted to keep track of what I was doing..

Chip has a VID of 1.1625 and stock voltage of 1.182 (or something similar)

So far it seems happy to do 4GHz at stock volts set to 1.185 locked. This is currently testing for stability.

Only slight concern I have is the temps but I'll look into that.

Edit: Currently about 45 mins stress tested all fine... The Vdroop is quite big, down to 1.136 V which I'm quite surprised it's still running at. Temps at 59 degrees

Ok so got up this morning at it was still crunching Prime95 away so it's over 7 hours stable at 4GHz with volts showing at 1.128 which is amazing really.

Temps were better due to opening the window further last night... Was bloody cold when I woke up but it got temps down to 52.

Will post screenshot later.

Edit: Screenie at just over 16 hours stable.

dedication there, risking hypothermia in the name of overclocking!

We salute you!

Nice OC, my quad needs sillyV to get even close to 4Ghz, 1.2 is amazingly low and I guess <60oC load is decent

Battling the elements for the higher overclock!!

1.12 is the voltage.. very very low. My Q6700 took like 1.7V to get up to 3.997GHz... Never made 4GHz which sucked... The FSB was set to be bang on 4GHz but it just went under.

As for the temps, I think they should be lower.. I get that they run how but this is a triple rad all to itself under a Supreme.

Ramp it up to 1.4v and see if you can get 4.6+ ghz.

Then attempt 5ghz with 1.6v

Oh I'm planning on it

Thing is I just aint happy with the temps...

By the way I've stuck a screenshot in the post above of the stable-ness with very little voltage for 16 hours.. quite chuffed with that.

Ok so just well lumped it up to 4.5GHz at 1.35V at it seems stable. Well it hasn't just crashed out as soon as I'm priming. Temps showing 70 on core temp and 62 on real temp which aint great but there ya go.

Here is a super pi too but I'm looking for below 10 seconds before I stick in the hwbot.

Neeeeeeeeeext!!

Stick 1.4V through it and up it to 4.75GHz-ish and it booted and was about stable enough for a SuperPi run and 1 min of Prime95 but then BSOD'd.

Got the time I wanted out of it though.

Bear in mind these are just rushed with only tweaks to CPU voltage as I'm going out in a minute... I'll have a read up on the Maximus's FSB Termination voltage and CPU PLL Voltage as I have no idea what these can be set up to.

Mmmm yummy:

Lol, 4.75 @1.4v is abit ambitious. I think 4.6 @1.4 will be prime stable.

Give occt a shot. 1hr stable test, is good enough for an everyday pc, for gaming etc.

I'm guessing that 4.75 will need 1.5v, 5ghz 1.65v.

What voltage are you wanting to use 24/7? Also whats cooler are you using, by the looks of it a stock intel with copper base?

At 4ghz on a true, you should be able to keep it under 40c with a room temp of 20c.

Keep up the clocking, I'm wanting one of those chips, saw a lucky chap bag one for £110 on ebay!! lol. But as trip ddr3 is alot cheaper now, it makes no sense for me to spend £220 on a c2d. As the i7's are so much faster.

That's the one thing i'm unhappy about mate.. Look at my sig.. It's high end water cooling single loop with just the CPU in it. Need to see if the block is on right.

This chip seems pretty good for clocking though with the v low VID. I've found some voltages for the PPL and VTT so will sort those now.

I'll probably be happy with 1.37 volts at 4.6 if it lets me.

Ok so after a waterblock reseat back on to a lil stability testing at 4.5GHz with 1.36V pumping through it. Failed yesterday at 17 mins but I think that was due to heat.

Temps aren't amazingly better but 5 - 10 degrees at load is nothing to be sniffed at.

Will post back how it gets on.

Look brilliant mate, I looking for that kind of chip, E8600 ftw. Its will ramp up your 3D Mark06 a lot higher then a quad so show us then.
