Specs: Windows 98SE, Pentium III 533MHz / 256MB
I have an old IBM 300PL 6565-60U I want to use as an 90s/Early 2000s gaming PC. I would like to upgrade it's 533MHZ slot 1 Katmai PIII to a Tualatin PIII. I believe it is this processor. I realize I need a slotket adapter. Will this work?

"I realize I need a slotket adapter"

The CPU you linked to uses "SECC2242, SECC2576" sockets which I believe are Slot-1. The sloket is for socket 370 CPUs.

One of the differences between the Katmai & Tualatin is the voltage, so you're going to have to check what's supported by the motherboard.

✔ Best Answer
A slotket will only convert your Slot 1 interface into an FC-PGA1 socket, which Coppermine used. You'll also need something like this Lin-Lin adapter to sit on top of the Slotket to give you an FC-PGA2 socket.

Keep in mind that some older OEM boards will not run Tualatins with 512K of L2 (the Pentium III-S). I had a few BX-based IBM and Compaq machines that would run 256K Tualatins, but would hang at POST or not boot at all with a 512K PIII-S.

I guess a Coppermine would be fine too, I just want something at least 1GHz.
