Is a used CPU worth more or less if it has been lapped?

Just sell as is and ask if they want the chip lapped, which you can do for extra $$$. You can always lap it later but you can't unlap it once you've already lapped it.

Say lap again.

You would just be removing the lettering identifying what the CPU is. 99% of buyers will be confused by it. Don't do it.

Worth more to a much smaller set of possible buyers. Worth less to a larger population. Essentially un-buyable for some people too.

Only way to up the value from stock is by having Kingpin clock it, lap it on camera, clock it again to show gains, declare it golden, then include a spec sheet.

unless you find someone who specifically will pay the premium, yea, its a used CPU for all intents and purposes

I would pop it and put one of the copper lids from ebay for a few bucks on rather than lapping and then thermal epoxy the original back on before selling. Better yet, fix your mount and run bare die like a man :D

depends on if you are selling to one of us.
We arn't the regular ebay consumer.

Even being [H] I wouldn't touch a delidded cpu without a massive discount. No telling how hard that chip was pushed, especially if the user felt the need to delid it.

Lapping a IHS is not the same as Delid. Where are you coming from exactly?

Regardless I disagree with that as well. If a properly delided Intel from many of the series that Intel did a horrible job with the under IHS compound job was already done and the cpu was validated as fully functional, then the threat of damaging it during the IHS removal has already been passed. So if you are actually [H] then that would be a bonus. Also there are a number of CPU's that the IHS isn't flat. So not lapping it as a [H] would mean you arn't [H] wouldn't it? As extracting every ounce of overclocking headroom wasn't extracted.

Luckily my current cpu's IHS is flat as a razor and is soldered inside. Thus I don't have these issues but my 3770K was delided and lapped and then went far better than before. Still running it at 4.5Ghz today.

My bad, been a while since I read the op. Have just been following the comments.

Same concept tho. I wouldn't pay a premium for a defaced cpu that was owned by someone who was chasing performance so hard they lapped it. Much more likely to have had higher voltages \ etc pushed through it.

If I wanted a lapped \ delidded CPU I would do it myself and make sure it was done right, on a cpu that I know hasn't been abused.

This all sounds good to me. At this point, it's an extra CPU (I needed more cores, so I upgraded) and I was just curious if lapping would be perceived as a value-add or something to be avoided.

If you can actually convince someone that a used and literally scuffed up CPU is somehow worth more, then just quietly take their money and move on. ;)

You could just offer to lap it for a potential buyer as an incentive to buy from you, if the buyer wants it lapped. Best of both worlds since the buyer is assured it wasn't pre-lapped and abused and if they don't want it lapped - no problem.
