Anyone ever seen a K6 with weird part numbering ?
Old K6 numbering.jpg
Never seen a K6 CPU using the PR2 numbering and having a look on Google it seems to suggest this is one of the first variants of the K6, 2.9v also leads to me believe this is one of the 350nm models. I have one of the later 250nm versions I wonder how this older model compares, not sure I would use this one tho as it appears to be NOS and still unused/sealed. Still there is something special about being the first person to power up a new CPU and see it roar into life.
Wikipedia has a little info on this and its one of the 350nm versions, bet it runs hot as a furnace.
Yah they started off with PR numbering then killed it quick. I don't think that one will be too super hot, they only got real hot when pushed to 200 and above and needed more than the 2.9V, The 233 needed 3.2... you might find that one does 233 with 3.2 and a socket A heatsink on it. Though you probably want to keep it "nice" since it's unusual marking, and I have seen that kind of printing damaged by wet heatsink compounds and stuff required to remove it, so maybe wanna get one of those graphite pads or something. I've got a 3.2/233 and test run it on a couple of boards, but chickened out when the regs got ouchy hot, so until I find a board that it doesn't seem to want to kill, it sits in the spare CPUs box.
I'm thinking this one might stay in its seal, I have a 233 K6 so this one likely wouldn't get overclocked.
