Hello, Greg.
Fido has been farkeled down here over the past few days,
so I didn't see what you had originally posted.

I know you didn't write what you quoted to Wayne C., but I have a
question about it, for you or any/ALL.

I've looked at documentation for a number of mainboards which use SDRAM
DIMMS, but can't recall any manual telling about support of 2-clock vs.
4-clock DIMMS.  Is my memory failing, or can you or anyone else here
come up with "motherboard documentation" about this problem?

So that part done got Wayne C's BVD's all in a knot, but I kinda suspect
that 2clock/4clock thing was a short-lived problem, back around 1996,
with just _some_ of the memory used in systems which could use SDRAM
sticks.
