a. The option part number contains two DIMMs of the same size.
b. The feature code contains one DIMM.
c. This option is supported only at x3950 M2 one-node and two-node.
The number of installed DIMMs and memory cards as shipped is specified in the
server model description. You can obtain details in the latest version of
BladeCenter and System x Reference Sheet (xRef) at:

The DIMMs operate at 533 MHz, to be in sync with the front-side bus. However,
the DIMMs are 677 MHz PC2-5300 spec parts because these have better timing
parameters than the 533 MHz equivalent. The memory throughput is 4.26 GBps,
or 533 MHz x 8 bytes per memory port, for a total of 34.1 GBps with four memory
cards.
The server supports up to four memory cards. See Figure 3-12 on page 113.
Each memory card holds up to eight DIMMs to allow thirty-two DIMMs per
chassis.
