Lapping Q6600

[Leeghoofd]

Ow you got a GO cpu, grab this then mate :

Thanks again!

Same results now (both cores same temp under load) but coretemp shows 4-5 degrees higher than ITE. I am not converned with that, just happy both cores are reading the same.

Before I lapped, I can hit 4 ghz stable, but I have to turn up my fans and water pump to the point where the noise bothers me. Hopefully in a few days after the AS5 cures I can hit 4ghz stable without all the noise.

I also lapped my Q6600 B3, it was really succeful job
Temps dropped from 72-82C to 56-69C on 100% load with QMC. Not bad.

Ano no that liquid in jar is not water, it is industrial grade ethanol.

Nice results BullDog, and i am happy people are trying this.

[BulldogPO]

I have done it before for two E6600, with pretty similar results.

coretemp 95.4 will give you accruate temps. A lot of people are mistaken their temps because they are still using coretemp 95.0 please install newer version. Reason being my temps raised 10c. And luckily enough someone told me about it.

I will be lapping my E6850 when i have some spare time. And hopefully get some watercooling gear withing the next 2 weeks

very good results ! my sand paper is in the post !

i would like to ask what do you use the rubbing alcohol for ? and how do you stop dust particles from getting under the IHS?

i was thinking of using electrical tape or masking tape , something like that? and putting the little plastic cap thing on whilst doing the laps is this enough?

[BulldogPO]

It does not matte if particles get under the IHS, and if they do then dipping in acohol removes them. I have lapped total of 4 socket 775 CPU´s and never uset anykind of masking tape.

nice guide, some guides tell people to use pressure. iam glad yours didnt.

Like sharpening knives - repetition & light pressure not fast & hard

NOKIA IN FINLAND!!! What? Next your gonna tell me Dell is US based

Ahh... to not get any sleep - makes me a little

I use Alcohol for cleaning the HS to remove any particles or etc. You can use tape to cover the edges and keep the plastic thing to save the bottom.

i lapped my Ultra 120, and my cpu, got it up to 3.5ghz........not bad for a B3.

[Ic3man]

Finished rebuilding my rig so heres a few temps comparisons:

Before 3.6 @ 58c avg 100% load
After 3.6 @ 48c avg 100% load



Ambients the same @ 22c, so not a bad drop in temps (-10c)

Also increased the clockspeed and temps are still much lower - currently priming @ 3.7 which averages @ 49c - 9c lower than before with 100mhz overhead! Still not managed to sort out the temp difference between the cores but hey I cant complain.

[annaconda]

nice

[scaramonga]

How do you get all they readings in PC Probe 2 Ic3man

Something you edit or something I'm missing?

[Ic3man]

Something you're missing m8.

I have the blitz motherboard . I don't think the other p5k's display all the settings.

[Ic3man]

Now upto 3.8 12hr p95 stable and still a fair bit from 60c

[it_burns_when_i_pee]

real nice results iceman

i saw similiar temp reductions after my lapping job. was getting 19 idle at stock speeds.

but now after overclocking to 3.2ghz im seeing temps of 45-50 under load. so just comparing mine to yours, if i could achieve any higher clock speeds i'd see higher or at the very best similiar temps than what you got. but considering you have a quad core and mine is only a dual, it goes to show how better a finish you got on your setup.

i think i'll take mine out and lap the cpu to a better finish

nice guide, some guides tell people to use pressure. iam glad yours didnt.

Applying pressure doesn't really hurt as long as you can manage to apply it quite evenly, and that's the tricky part right there. I actually lapped my E6600 using quite a pressure, and it came as good as my Q6600 which I did with more care.

[Alik4041]

I use the chip protector backing then seal the sides up with masking tape...my Q6600 looked nice and flat until i started sanding it lol.

I said the same thing when I saw my q6600. It looks perfectly flat. When I saw the damn thing, I thought to myself "Maybe I got lucky with a flat q6600 " but looks like I was wrong

[it_burns_when_i_pee]

my E6600 is a B2 and cant get it stable on 400x9. it boots but comes up memory read error on loading the os. if i can get the same overclock as iceman i will be very happy

im trying different voltages but when it fails twice i have had to reset bios via the jumper & as you can guess is a pain.

voltages are

1.45 vcore
2.1 v memory
1.40 FSB
1.45 MCH
1.50 SB
1.45 NB
1.057 ICH

its stable on orthos, gaming the works at its current setup. anyone recommend a right heading for 400x9 as the combinations of voltages is quite large.

how did you clean the sandpaper after each rotation

[it_burns_when_i_pee]

i rinsed the sandpaper under water & used acetone to clean the heatsink or cpu surface

but when i lapped the cpu i didnt use water. instead i was putting drops of acetone which didnt last long. it was the first time i lapped a cpu and i was being a bit paranoid about killing it

I'm afraid of lapping but with these results I would rather move to the NON-xtremesystems instead of start show some sand paper love
