32 bits.

I've used matched pairs. Both pairs bought together from
the same vendor.

Yes. I know. But it is taking linux a lot longer to
go through the startup lists.

Once booted, the machine seems as fast as usual though.

Another good point. When I get a chance I'll yank 2 gigs.
The machine lives in a fairly inaccessible corner and I
can't just drag it out without some preparation.

Besides, I couldn't be typing this if the machine was
turned off... ;-)

Sorry.

I'll check in the bios, but I don't think so.

Thanks. That's ugly, since the manual makes no mention of it.

What is the reset button, chopped liver? To say nothing of shutdown with
reboot.

I assume you mean the mainboard manual ! I've never seen memory
slowdown mentioned either. I assure you it does occur even with
matched pairs and/or paging turned on or off.

Memtest will show you the speed whilst its testing. If you make a note
and change the configuration, run memtest again you will see !
