Upgrade Proliant 1500 with 2500 CPU card??

one post was fine, ...but 3?

The abosolute best upgrade path for the 1500 is a dual PPro board (if you
can find one, that is affordable. I have seen these sell for $750+ on ebay,
for the board w/o procesors or memory!). There is a company called PowerLeap
that makes a Celeron-based socket8 performance upgrade. They have a 500Mhz
model the will go SMP, and a 600 that will not. If you really want to get
jiggy with it, you can ditch the standard 500Mhz and opt for the 533PPGA
processor. That will give you 1066Mhz of dual processing power. I can hear
you moaning from herestop that! There is also a PII Overdrive that is a
socket8 chip that runs at 333Mhz with full speed cache. It is said to out
perform the PII450/512k processor. And, the PII OD can be used in SMP
configurations (these are not cheap, but they are less than the
PowerLeapII's). You might be better off sinking your money into either a
Quad system (4000, 4500, 5000, 5500) or a higher-end PII/PIII Proliant
server. 1850's (i know, they are only Dual SMP) are getting cheap, and they
scream compared to the 1500.

As for other CPU's, I like the idea of the AMD's, but they dont support SMP.
I have the dual 133/166 board. On the 1500, the system speed is determined
by the processor card, and the cpu multiplier. A P5/75 board runs at a
system frequency of 50Mhz, with a 1.5x clock multiplier. the 133 is a
66.6x2.0 and the 166 is 66x2.5. always opt for the higher system frequency,
and if you choose to run a dual config, make sure that the chips have
compatable stepping values. so, you could actually put 2 chips in there that
have 66Mhz frequencies with 3.0x and 3.5x multipliers. that would give you
200 and 233 respectively. I dont think the SystemROM supports the MMX chips,
so choose your CPU carefully!

this stuff is sooooo much fun, isnt it?
