I have this Cyrix/IBM CPU, which I at some point in time have lapped for better cooling. No idea of what it was though. Google results are quite ambiguous, so I'm asking the joint intelligence of vogons. What would this bugger be?

If it's dual it's kind of cool ... 😎

Please use the "quote" option if asking questions to what I write - it will really up the chances of me noticing 😀

21L0374 comes back as a 6x86MX PR233 (75x2.5 or 66x3, 2.9 Vcore) and as a PR300 (75x3, 2.9Vcore)
If yours had enough OC headroom to be worth lapping it's probably a 300.

I just found a CPU with the same markings on an auction site. It's an IBM 6x86MX PR266 CPU with 83MHz FSB, x2.5 multiplier, and 2.9V Vcore.
