The Intel UK Fax back specifically states that it MUST be 60ns memory
to work with an Endeavour at 66MHz bus Speed ie: 133Mhz CPU or 100MHz
but 70ns is OK at 60MHz bus speed for the 120MHz Processor.

I've noticed that Micron uses 70ns EDO RAM on their P133 computers.
I've always been told to use 60 ns at this speed, but I'm willing to
concede that Micron might know a little bit more about the issue than
I.

Typical. Almost every 133Mhz box I've seen is shipping with 70ns RAM (EDO
or regular DRAM). We just got a Compaq 100Mhz box in and it also uses
70ns RAM.

I have run 70 & 60ns RAM in my P100 with no problems. Sadly, I have 32MB
of 60ns RAM and BOTH simms have gold connectors which reportedly rot the
tin simm leads in the newer motherboards. It is cheaper to replace the
motherboard than it is to replace the SIMM's though (I couldn't really
sell them in good faith unless I new the buyer had gold leads on his PC).

Oh well
