Will Lapping a CPU affect resale value?

If I was buying a CPU second hand then it would be a bonus if it was lapped well.

Without access to a lapping machine (PhillyDee, smartass lol) it is a tedious process... Never lapped a CPU myself, but lapped the base of my old HHC-001 cooler and my god, I thought I'd be there forever!!

So if someone has already taken that particular ball-ache out of the equation, then I'm on a winner lol

part of my job is polishing metallographic samples to mirror finish so they can be viewed on a micrscope for cracks, and ive never lapped my cpu. might try it, have a diamond polisher at work that could bring it up nicely.

Do it by hand it`s so relaxing to do i loved doing mine

I've never seen or heard of a CPU dieing unless it has been abused in some way (physically or through excessive volts/heat). They *usually* just work or they don't... no inbetween.

I would personally say it ups the value a little.

I had a CPU die on me once...at least it possibly did. It was either the CPU or motherboard but my parents decided to replace both rather than faffing about trying to find out which was the problem, so I'll never know.

Lapping definitely reduces the resale value of a CPU, yes. Watch a few auctions on ebay and you will see a difference.

If I'm shopping on eBay and I see a lapped CPU I'm more likely to think "Ah, this guy has obviously overclocked this CPU" and not bid on it.

P.S. Ever since Intel moved from sockets and pins to LGA for all CPUs I've never had a dead Intel chip.
People silly enough to use AMD cpus will have CPUs die on them all the time due to bending the pins! Most recently I killed a Phenom X4 by breaking off a pin while trying to striaghten it

(I have access to a lapping machine )

I'd have never lapped my TRUE without one. I did get some very strange looks from the other guys in the lab though.

I don't think I'd buy a chip which had done 4.8ghz under phase from ebay. The lapping is irrelevant in my eyes though, as I'd lap it (again) when it arrived anyway.

Lapping didnt effect the resale value of my old q6600, sold within minutes of being put up on mm. It helped that it was a pretty decent clocking chip. But id be hesitant to lap my current i7 at the minute, possibly do it after ive had it a while longer and it's warranty period draws to a close. Not that keen on sanding either as a very sizeable part of my working day is spent sanding things.

I used to do some of that when I worked for a power generation company. Not sure how they would be for lapping though, I think the prolonged contact with the polishing cloth could lead to static build up? I could be wrong though. That aside it would work perfectly, especially if you arent liberal with the diamond solution.

Wouldn't bother me providing I could see the chip working before purchase or it was through a trusted source / had a DOA guarantee.
