Fat, good looking caps. Boots just fine.
Apparently, the original VIA KT266 chipset has all kinds of funny bugs to look forward to...
This came with surprise CPU that turned out to be a surprise... Thunderbird 1400.
Nice! Especially since I have one of those since 20 years, only that I cooked it some day...
IIRC, that bugger is unlocked by nature. It readily OCed via multiplier setting in the award bios.
Is it a 1400B or a 1400C?
And yes these chips are indeed easy to cook 😒
It is the 1400C for the 133 MHz FSB.

I actually bought that one for cheap and used, in 2002 or 3 to upgrade from a prized TB 700 that I had bought with some silly dotcom startup job money back when that was cool.
Mainly because 700 @ 1000 felt sub standard by then and the obnoxious nerd in me refused to buy a CPU that bore the name of a Microsoft OS, if not officially.
"Easy to cook", well, it depends.
Just don't ever move them anywhere near a power supply without a heat sink attached.
Mere negligence can mean to accidentally hook up a "live" PSU that for some freak reason turns on before you attach the heat sink, e.g.
But, I'm still ashamed to admit, I cooked it by ignorance rather than negligence. Back then, think I wanted to check whether a certain board does POST at all or something like that.
And, I assumed it would be ok to power it up for a mere second up to the VGA bios screen.
Turns out, it's not ok. Not at all.
What can I say? I was young and reckless. Also, to my defense, the chip was retired and just had entered "obsolescence purgatory". So I did not care too much. But it was the last of the CPGA Mohicans, even back then. I should have known better! 🙁
Yes I can remember this little deathbringing noise, too. "pfffff" just one nanosecond after power on and that's it. You can't do nothing against. When you hear it it's already too late.
Happend to me once, too, when testing all my SoA CPUs. Just had the cooler lying loose on top with some gentle pressure to make contact to the die but the heatsink clips unattached to not stress the socket mounts and my fingers and the dies too much to avoid cracking. Think it was a 1 GHz Athlon.
Very poor design, just like the regular P3s w/o heatspreader. Just that they didn't need that much pressure for the heatsink which made testing a lot easier.
