That's good...

I've had similar problems myself - where the SIMMs (or atleast one of them) hasn't fully "snapped" into place. I don't know why I didn't think of it.

2x 300 MHz CPUs are very nice, and you would see a nice bump in performance by going to dual 400 MHz CPUs, but at what cost? There are some nice, economical 4-way ultra clone systems (they take up to 4 CPUs, have 16 memory DIMM slots, PCI slots, and 2 1" high drive slots, it is aproximately the same size as an Ultra 2. I have one, and I suspect you could upgrade your Ultra 2 to a 4-way 300 MHz box for less than a 2-way 400 MHz box...

The value proposition really depends on the cost of the CPUs - around here, they are still quite expensive...
