8700k serves as a unique serial identifier for recognition.
Hi, I understand you're considering selling your 8700k to a third-party delidding service. From what you've experienced personally and tested, you seem to have a good chance of getting a decent chip. You're wondering how to be sure you receive it back as promised. Is there an option for an individual chip ID that can be scanned electronically? Or would you like recommendations for highly reliable delidding services? Just want to make sure you get the chip you sent in...
Back in the P3-P4 days, Intel used to burn a serial number into its CPUs that could be read back using a CPUID index but due to privacy concerns, I believe that feature got scrapped and computer ID got delegated to the optional TPM.
If you want to distinguish your chip from others, you'll have to put some sort of subtle mark on it that only you might recognize as such. Even then, there is a possibility that your delidder might ultrasound-clean the chips at some point and remove most types of markings.
The serial is located on the front of the processor named ATPO. OP wants to remove the protective cover. The factory ID is on the cover. IHS can be rearranged after removal. Perhaps the ID is also hidden in the QR-like pattern on the side.
Yeah, the serial number isn't on the IHS. It should be on the circuit board or the chip. Maybe I should use a delidding tool and handle it myself. How challenging would that be?
How challenging is this? With the right equipment, it's as easy as tightening a screw. Although I haven't done it myself, anyone who has shared a video about it says the process feels quite tense during the initial attempts. If you attempt it yourself, ensure the CPU is properly aligned, fully seated and square, and avoid over-tightening beyond the point where the IHS starts to shift, or you risk damaging the SMDs beneath the IHS edge.
So what you're thinking is right. Using the delidding tools helps lift and remove the IHS, take off the old clue from the circuit board, clean the die gently with a cloth and maybe some alcohol without damaging it, apply the liquid metal paste, put new adhesive on the board, reinsert the IHS, and let it cure for about two hours. Does that cover everything? It doesn't have to be done in a clean room.
