Old P2

[PolyPill]

I was wondering if anyone could tell me whst the highest powered Pentium II CPU is available and if I could be directed to some where that could sell me 4 of them. I think it maybe be 600mhz, I know there is at least 450mhz for sure.

Reviving an old quad processor server and I've already established it will not take a P3

The highest Pentium II processor that I know off hand that is the fastest, is the

Pentium 2 450mhz with 512k..

If you say 600mhz, that would be two different flavors of Pentium III's that are now hard to find. (600EB (133fsb), 600E (256k second generation, and the 600E with 512k based on the Katami core)

Everything else seems to be the first generation XEON around that area if you want more power. Slots holdings are different for that big ole cartridge slot 2 or something (cannot remember)

You can still find Pentium 2 450's here in the classifieds, Ebay, or some places that sell used CPU's and parts.

Have you checked some of your local computer fairs?

Hope this helps..

Anyone else add to this...??

I said I thought there was 600mhz, guess I'm wrong, if I knew for sure I wouldn't have had to ask on the forum.

Also I've noticed things like 256k cache and 512k cache, I thought I even saw 1mb cache. Basically I want the fastest thing possible in a matched set of four.

1.6ghz, that's not too shabby. Plus it's stacked with 10K rpm scsi hds but right now I've only been able to put one 333mhz cpu in cuz that's all I have in P2.

They don't "stack" like that, so four 450's doesn't magically equal 1800mhz... For any one given application, it will only go as fast as a single PII 450 will run it. The benefit of multiple processors isn't doing ONE thing faster, it's doing MANY things without any slowdown.

There is a difference there

I know, it's for a server not playing quake, so with many small instances of threaded programs it will get some pretty damn good speed for the price.

P2-450 were the highest ever made. They have 512k cache at 1/2 core speed and work at 100x4.5. I have one here, complete with heatsink and fan, if you want it let me know. Stepping SL2UT.

However, make sure that your server can take the 450s. There were 2 kinds of P2s, the first ones (233, 266, first 300s) based on the Klamath core, and the later ones (350, 400, 450) with the Deschutes core. The Klamath are 35 micron technology, work on 66 MHz FSB, 2.8V and are very bad overclockers; The Deschutes are 25 micron, 100MHz FSB, 2V and decent overclockers (not stellar). There also were some intermediates, 300 and 333 Deschutes running on a 66MHz bus.

Many first generation P2 boards, including server boards, will only take Klamath CPUs because they don't have the 100MHz FSB but above all because they can't give the appropriate Vcore. If your mobo is made by Intel, chances are it uses the 440FX chipset, which can only be used with Klamaths.
