Hey friends, I stumbled across this video today: https://www.youtube.com/watch?v=736iXRdXuTE

Looks like he was able to order a dubious Chinese S7 Pentium MMX 300MHz CPU which was likely a mobile CPU in some sort of interposer configuration. Has anyone tried one of these? Are there any downsides vs running a traditional Pentium MMX 233MHz?

Basically if there are no downsides insofar as energy, heat, compatibility, etc., then it seems like this is probably a pretty good deal. I might be interested in running this myself. I'd love to gather thoughts here. Thanks!

We're trying to keep it secret so only refer to it by the Intel codename Tillamook shhh, don't whatever you do put that in the search bar and find out the tricks or you'll end up spending money.

Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.

It was overclocked, hence it has a shorter lifespan. You'll have a better luck with a K6 processor.

Looks like the hard part is finding one of these Chinese built fake S7 chips which are really a Tillamook and an interposer in some sort of enclosure 😜 I've seen photos and videos of them but can't find them anywhere. Alas...

Shorter lifespan? The P55C was probably the most over-enigneered CPU in history, capable of running vastly out of spec for decades if needed, just look at all the people who ran them at 3.3V on motherboards without split voltage...

I've run a particularly good Pentium MMX at 3.5x100MHz, and most I've tried handle 3x100MHz. So a Tillamook on an interposer clocked from 266 to 300MHz is peanuts.

It is safe to say that I'm not a fan of overclocking 😅.
