lapping your cpu is it really worth it? considering i have already oc'ed my cpu is it worth it?

depends on if your CPU's IHS is flat or not, and if you want to squeeze every last MHz/oC out of it.

no idea if mine is concave or not x_x i might do it anyways. my waranty is screwed anyways..

From what i have seen i don't think it's worth it, especially if you haven't done it before. If you want to try it i suggest you use an older processor/heatsink first and see how it goes.

As DMB2000uk mentioned it is about getting a flat surface more than anything else. You should also get it smooth as well which is characterised by a very shiny mirror like surface but this isn't as important as getting it as flat as possible.

I don't think you will get a huge reduction in temperatures, you are talking about a couple of degrees Â°C, maybe a few degrees but nothing more.

What CPU is it? If it's a s939 chip you can remove the IHS.

so... couldn't you like take a dremel to it? to remove the ihs? why did they start putting on ihs's ? wth when we get better cooling with it off. doesn't make sense cause not have the ihs could save them some mullah.

I have heard that it's better with the heatspreader off as well, i read one of the reviews from here as it happens. The following quotes are from a review about the x2 3800, but i think the heatspreader would apply to most AMD chips with a heatspreader, if not all.........

One issue I am seeing on message boards around the web deals with the IHS (Integrated Heat Spreader)....

The consensus among this group seems to be that the IHS seats poorly on the processors cores......

I'm waiting to hear back from AMD on this issue, if there actually is one, and hoping to find out if there are plans to improve the IHS or redesign it totally. (Update: AMD does not plan on changing the HIS on any Athlon processors)

Personally i wouldn't remove the heatspreader on my Athlon, i wouldn't be confident that i wouldn't damage it, and i get pretty good temperatures anyway. I would possibly consider it if i had done it before or if i was trying to squeeze every last Mhz out of it, which i am not.

Don't try remove the IHS from an Intel proc or an AM2 cpu!
YOU WILL KILL THE CPU IF YOU TRY

The IHS is soldered onto the core

Well in for pointing that out. The article is about 939 CPU's but i can see how people might think it applies to all AMD CPU's with a heat spreader, or any CPU for that matter.

LOL

I have plenty of IHS key chains

That article should help ya out ;) I've done it a dozen or so times just to get a little better overclocking results.
