Do the math. If you have 4 SDRAM DIMM's, each 8 bytes wide,
that's a 32 byte wide data stream, also called 256bits. And,
clocked at 83.33MHZ, you get 2.6GB/sec, on a single bank. That
is what the board is spec'd at. The UP2K uses the same memory
architecture as an XP1000, near as I can tell. One can order
memory for an XP1000 and it runs perfectly fine in a UP2K.
Going to 8 DIMM's won't get you any more performance.
(I run both UP2K's and XP1000's)
