Tualatin PIII on an IBM 300PL 6565-60U

[sega dude]

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?

 

[jhu]

probably. try it and report back.

No, it will be a bad idea. You are better off weirdly just getting a northwood s478 and 845 DDR mobo, or an Athlon XP and Nforce2 mobo. All of that should be basically free, but will function much better (usb 2.0/agp 8x/etc). Slockets, particularly with Tualatin, are really really hit or miss.

I think the bios needs to support Tualatin, being an "IBM", and considering that without additional hardware the MB cannot run tualatin...

also most slocket adapters were pretty simple, and only made for Coppermine (Tualatin have some different pins, meaning you would have to find a specific slocket, or mod like this: http://www.mrufer.ch/pc/tualatin2_e.html

and there is another limitation, older boards for P2-p3 katmai may not be able to provide the correct voltage for the tualatin, meaning it will not boot without a slocket with it's own VRMs (Powerleap) or without a pinmod forcing an overvolt on the CPU (tualatins were working with 1.45-1.5v I think, old P2-Katmai boards were made for 1.8-2.2V or something)

basically... it's not a good idea.

^^ all of that and more!

You can find great retro gaming PCs for peanuts or free that won't be such a PITA. It would suck to pay $$ for a Tualatin (or coppermine) and a slocket, only to discover that you are going to have problems.

The real icing is that even if it all worked 100%, you're still stuck with SDRAM and a proprietary power supply. With a basic ATX midtower and an AXP or P4, you can be set with DDR and AGP, pretty much prime for retro gaming of that era.

I have a couple Athlon XPs and Socket 462 boards laying around. One is a Barton 2500+. Too new for what the OP wants, probably.

That'd be perfect. Even if he felt it was 'too fast', he could just run it at a lower FSB. But gaining USB 2.0 and decent AGP would be very much worth it along with not being stuck with a proprietary box like the 300PL.

I think K7 in general is not a huge amount faster than tualatin at the same clock...

so yes, lowering FSB or multiplier (some bartons were locked), could deliver the same performance, but with a newer platform, some socket A boards had Sata support, most had AGP 8x support, and if you need ISA (good for your old soundblaster) or AGP 3.3v (good for Voodoo 5500, or 3) it's not impossible to find a board for that (but you might need to use SDRAM, and things like "kt133")

Or just turn off the cache and watch your system respond like a 80286 of yore

Hahahah! Yeah that does tend to turn those systems into useless slag.

Just hit eBay and look for something like this:

Nice little compact socket 478 barebones. Drop in a Northwood, some DDR and an AGP card, and you're laughing.
