Hi

I've just bought a Proliant 1600 which has 1 x PII-400, and is dual cpu capable.

I've seen intel processors being sold as "match pairs" on ebay.

1. "Match pairs" does anyone know anything more about this term?
I know that it is NOT in relation to the actual speed rating, ie PII-400's, its refering to something else.

2. Any problems in using non Compaq badged/branded intel cpu's? Is there any difference?

Thanks for any help in advance.

Yes it refers to the Stepping Revision of the processors

Along with another processor you normally need the Voltage Regulator board too

Depending on the processor it may be on a riser card, which means Compaq parts only (ie major expense)

You can get the stepping revisions from the sticker on the CPU itself (normally) and Intel have charts on what stepping revisions they released for each processor available on their web site

Cheers Sonic, thanks.

from what I remember, stepping doesn't apply to PII. Even if you put in say a PII 450 then the server will default down to the speed of the slowest proc.

Given that the PL1600's are probably all out of warranty now, it doesn't matter whether you use non CPQ badged processors.

In relation to the voltage regulators, you will need a Processor Power Module but you don't need a terminator board on the 400's.

Just found this on the internal page which may be of use:

Unlike the PL1600 PII 6/266 and 6/300 Processors, the PII 6/350,6/400, 6/450, and PIII 6/500, and 6/550 Processors are not mounted on their own Processor boards but are inserted directly into the processor sockets. As a result, the later servers do not require a Processor Terminator board in an unused Processor socket.
The PII 6/266 and 6/300 servers require this Processor Terminator board, Spare Part Number: 270119-001, in a single processor configuration.
The PII 350 through PIII 600 servers require Processor Power Module, spare part number 327660-001.
All processors still require specific Processor Power Modules, PPMs.
The same Processor Board is used between the Pentium II 350, 400, and 450MHz Processors and the Pentium III 500, 550, and 600MHz Processors

I know the info relating to using a two cpu's of different speeds, the machine will only perform to the lowest speed, but as Sonic states above, there are these "stepping revisions" on the cpu label.

Just being a bit cautious really, as I have seen a lot of compaq cpu's being sold as matched pairs, and I know its not in relation to the 400mhz indication.

BTW you mention a page "internal", do u work for compaq? (sorry HP!)

Well, normally as has been said, matched pair indicates the stepping of the particular speed of chip, for instance, I have a pair of matched (SL2S7) stepping PII-400 cpu's in front of me that are only 17 apart as well on their serial numbers.

Cheers,
