Lapped Conroe

Went over my conroe again - took some photos this time(badly):

yikes that's shiny, right down to the copper, very impressive

I might do mine again, i only lapped until the corners were at the same hight as the center. Then again my temps are fine so maybe not.
Hows it affected your temps?

w3bbo · 23 Feb 2007 at 16:27

Dunno, pc is in bits hence getting the time to do it. When I first lapped it (to 1000 grit iirc) it dropped load temps apx 10c iirc. Have some spare time atm so I thought I would be anal and get a perfect mirror finish - cant see it affecting temps at all tbh as you only really need to go as high as 800 - anything higher is...well....anal lol.

This is an OCers forum so we all do things that are anal in some peoples eyes, how long did you spend getting your rig to hit 4Ghz stable

Wow very shiny! Has it effected yout temps much?

Lapping the cpu got me to 4ghz in a way. Lapping it caused temps to drop so more vcore could be applied but yeah, getting anything past 3.8 stable took some doing tbh.

10c is pretty drastic, was it curved before ?

w3bbo · 23 Feb 2007 at 19:07

Yup. The edges of the IHS had been gound down by intel already. I just perfected there idea of lapping

Most IHS's are concave to some degree imo. Some folk have had better results than 10c.

silversurfer · 23 Feb 2007 at 19:16

Im lucky then because my IHS is level, I measured it with a razor and no light shines through from the other side. I have heard it tends to be one or the other, mine is a version A so cant have it all unfortunately

w3bbo · 23 Feb 2007 at 19:19

Mine is a version A too - don't let that put you off. Not many B's get 4ghz stable on water tbh although they do seem to overclock better than a's on average. What speed are you at now?

I wish i had run mine before lapping it just to see the difference but sadly no.
I was honestly shocked to see how concave the IHS was, i almost stopped the lapping thinking that maybe it was meant to that shape :eek:

w3bbo · 23 Feb 2007 at 19:27

I wasn't scared about lapping too much, it would take some serious rubbing to get past the IHS lol. I was more concerned with knocking of one of the chips off on the back.

Pretty nice lap job there but how did you make sure it was flat?

When I did some lapping to a heatsink years ago I had to use plenty of water and a glass sheet to make sure the pressure was even and the end product was flat. But how would you do that on a cpu?

ah right, I might try overclocking some cold night with the window open. I've had 3.6ghz up for a few days but it wasnt orthos stable, Im at 3.4 with no problems

Its all a bit theortical with me since I dont really need the power and my ram is really slow too so that would throttle it anyway though Im unlinked. I want to make 4ghz for a laugh, they have a chart on xs for 4+
The cooling ranges from water to liquid nitrogen, I did spot at least one Ac 7 which is what Ive got

He probably lives within the artic circle though

w3bbo · 23 Feb 2007 at 19:36

Yeah I have submitted my clock over there and got No# 1 for a watercooled E6600 (Ic3man)

. Its a nice feeling considering XS is up there as one of the foremost overclocking forums - dunno how long it will stay that way.

Same method.

I would lap my E6300 if I wasnt scared of breaking it lol. Im happy with a 2.8Ghz OC I dont need no more till crysis ect come out I will be glad when CSS supports dual core will nearley double the FPS as its CPU dependant

.

silversurfer · 23 Feb 2007 at 19:40

Yea they said that will be soon I think. How is it cpu dependent, have you got a 8800

1337z0r · 23 Feb 2007 at 19:43

You can run a E6300 at 3.0 and a 7300 on decent graphics with no aa or af and get the same FPS as me with AA and AF. People with 7900's and and AMD3800 Dual core or stock intel E6300 will get less fps.
