Hello, Wayne.  I overheard you talking to Greg Easthom about- -

 
 GE> The typical indication of the wrong type being used is a system giving
 GE> error beeps and not booting as it cannot use the memory installed. The
 GE> system will not proceed past POST (Power On Self Test). 2-clock was
 GE> only used in 66 MHz systems. All PC 100 and PC 133 memory is 4-clock
 GE> only.

Earth to Wayne -  saying "2-clock was only used in 66 MHz systems" isn't
the same as saying that '66 MHz systems can only use 2-clock', is it?

 WC> Thanks, that was what was holding me up from committing to purchase
 WC> and it seems I was right to do so as this machine's buss runs
 WC> at 66 :-(

Heck, Wayne, you started this whole discussion about your HP machine
while mentioning you wanted some  PC100 memory to upgrade it - - I told
you along the way that Celeron 433 runs at 66 MHz, and that PC66 memory
would work in there, and now you get all hung up over that??

Your above is very likely an incorrect conclusion. Greg's source  didn't
say that 66MHz systems used _only_ 2-clock, did it?  AFAICT from
Kingston memory website, they are selling PC100 sticks as memory
expansion sticks for your precise model of HP Pavilion.  So if those
would work in there, and "all Pc100 and Pc133 memory is 4-clock only"
per Greg's source, then your machine should support 4-clock PC100
without any problem, shouldn't it?

BIR, this "foundling" machine came to you with a 32 and a 64MB stick in
there.  Have you taken a look at those sticks and seen what may be
written on any stickers and such which may be attached in order to try
and figger out what types of sticks could be used to upgrade it to the
full potential 2 - 128 MB sticks?

 WC> As to documentation in the manual for an H.P., ha.
 WC> Guess I'll snag up some cheap EDO from Ebay for the NEC and see what I
 WC> can get going here while waiting for some of this rather unobtainium
 WC> SDRAM to make an appearance.

Change course and now concentrate on working toward upgrading the SIMMS
in the NEC if you like, but I don't think that SDRAM memory which would
work for upgrading the HP is all that hard to find.

Good luck - - -  JimH.

P.S.
 WC> I did download the DIMM SDRAM specification revision 1.0
 WC> as a PDF to see what I may be able to squeeze into the H.P.
 WC> but the darned timing spec's on the PC100 and PC133 seem to be awfully
 WC> picky about whatn they'll accept and still present valid data.

What a surprise! :-).
