Question Do CPUs have there own serial number?

[sodium.in.toilet]

Intel is sending me a new cpu because I RMAd the one I bought. It says they're sending me another 7640x but it has a different serial number. Does this mean anything? I thought they all had the same serial number with different batch numbers. Whenever I google this nothing really comes up.

yes they have serial #s, and batch #s - what's more important is if the Stepping is different from what you have - may mean bios needs to be updated etc... but probably not an issue if you're fairly up-to-date

I bought a new motherboard and havent been able to get to bios yet, but I think it should be fine considering the 7640x came out when x299 was launched. I didnt know cpus had stepping, I hope it overclocks better than my last one.

you should be fine, the serial # is etched to the lid so it's in their warranty record. recently I guess folks have been delidding and selling bogus spec'd processors on eBay but that's not a concern here - the serial # also shows on the retail box. good luck with the build

I got the replacement and the warranty sticker says "Condition: good"

I really thought they were going to give me a new cpu, not some random used one. I'm honestly surprised it even survived shipping, the clamshell thing wasnt even closed and the cpu was just sitting in there sideways...

 

[Mr.Spock]

yeah, they sometimes RMA with a "refurbished" chip that's tested ok... haven't had it happen yet

I'd be more surprised if they had given you a new CPU. All the Kaby Lake-X CPUs that will ever be made <em>have</em> already been made, so the supply of new ones Intel still has hanging around has likely been dwindling; Kaby Lake-X CPUs were retired in 2018, nearly a year before the consumer Kaby Lake CPUs left production.

Kaby Lake-X CPUs were never popular, so it's not surprising to end up with a refurbished one. GPU makers will quite often send you a more recent GPU, but that's easier to do since going from, say, a GTX 1070 to an RTX 2060 doesn't require a new motherboard, which you can't say for CPUs.

My thinking was that nobody really likes this chip and anybody going with x299 wouldnt choose it, so I would assume they would have extra ones that didnt sell. I didnt expect to send them my i5 and get an i9 back because they are still making i9s for x299.
