E6600 overclock

Mr_T · 8 Jan 2007 at 20:51

Hi,

I've currently got my E6600 running at 3.2 (8x400) but idle temps are about 55 degrees.

When I stress test it with Stress Prime 2004 (running two at once)
I get an error after about 5 - 10 mins

Durring the stress test I get temps to about 67 degrees

I understand lowering my Vcore might help, but are there any adverse effects of doing this?

BTW I've got a scythe Ninja.

Ok I've tried remounting the heatsink and there is a nice amount of paste on the chip. Installed TAT, when running the system at (400x8) I get the following idle temps...

which seems damn high, also on TAT & system properties its reporting the Max frequency to be 3600MHz?!

cpuz is showing...

Vcore is set to auto, so probably standard. 1.55v

Mr_T · 8 Jan 2007 at 22:00

Ok I've set it to 1.4v and load temp is 63 degree
Orthos ran for about 1 min before getting an error.

Might have to invest in a better cooler, or maybe I just have a hot chip?

I put the entire packet of paste that came with the heatsink...
Idle temps @ stock are about 40 degrees.

The most stable I can get the chip is 2.8, which is still great but I'd like to get more if possible...

Mr_T · 8 Jan 2007 at 22:26

So you would say that this is too much?

If that look like way too much whats the best way for me to clean it?

Mr_T · 8 Jan 2007 at 23:28

Ok I took off a lot of the paste & remounted the Heatsink & Fan.

I'm currently stress testing it @ 3.2 having set the mem voltage to 2.1 and the Vcore to 1.45

Its been stable in in Orthos for the past 30 mins and temps are about 72 degrees.

what kind of temps are other people seeing with this chip at 3.2?

Mr_T · 9 Jan 2007 at 00:24

Ok I'll order some Artic paste tomorrow,

I had no stability issues with the system at 400x8 despite the high temps.

I'm trying 356x9 @ 1.4Vcore now and under load its at 64 degrees

However my mem timings have gone from a tight 4-4-4-12 to 5-6-6-18

whats the real world difference between the two?

Strange thing happened this morning, when I had it set to 8x400 last night @ 1.45Vcore I scored 12,000+ in 3DMark 05
What I noticed was that on the cpu only test it was still doing around 5-7 fps

This morning when I've tried 3DMark 05 again i'm only scoring 8000+and the cpu tests are coming in at 1-2 fps

Is this a case of the cpu needing more vcore?

Lol gOOd one!

lol, yeah I know... stupid is as stupid does

I've just put the machine back to stock for now... and I'm getting 4-5fps on the cpu part of 3dmark05 and my final score was 11696

I run my e6600 @ 3.2 on stock cpu voltage, thats 1.2v for me. idles at 25-27 load is around 37-39 running dual orthos, cooled by a tuniq tower 120. Something is definately up if you need that much voltage and are generating so much heat, could be a poor ihs they seem to be very inconsistant on conroes. Try running the 9 multi with the fsb at 356 you may have more luck

Do you think lapping the cpu & heatsink is worth a go?

Because at stock speeds & voltages I am getting about 42degrees idle!

If only I had access to another cpu so I could determine if its the processor or the heatsink!

Mr_T · 9 Jan 2007 at 12:53

Not sure on what grounds you could RMA the cpu though, I mean it works at stock speeds little warm maybe but stable.

Mr_T · 9 Jan 2007 at 16:10

Well tonight I'm going to take the cpu out and take a look to see if its concaved. If it is I'll consider lapping it, reading elsewhere on the net it seems that quite a few ppl have hot E6600's

I'm not going to RMA it... its the luck of the draw and its not as if the cpu doesn't work.

Is there just as much chance that the heatsink could be as concaved as the cpu?

Mr_T · 10 Jan 2007 at 09:46

Ok this is where I am with my hot E6600.

I got fed up of constantly fiddling around in my case so I've mounted the system on my desk outside the case.

I then took the cpu out and wiped off all the thermal paste and checked the surface of the IHS which is seems flat.

So I did the same thing with the Heat sink surface... also seems flat.

Now when I mounted it all again (outside the case) @ stock volts & stock speed
I get idle temps of 48 - 52 degrees, which seems really ****! The interesting thing is when I unplugged the heatsink fan the temp didn't change?!

I've got a Tuniq 120 & AS5 arriving tomorrow so fingers crossed that will help, but can it knock 10+c off the temp?
