Memory - Intel SRMK2 - Server Platform - 0 MB RAM Technical Specifications

3.5 Memory

The serverboard has four DIMM sockets. The serial presence detect (SPD) data structure which
2
is programmed into an E PROM on the DIMM instructs the BIOS on the SDRAM's size and
speed. The minimum memory size is 64MB; the maximum memory size is 4GB. DIMMs can be
populated in any order, but due to the 25 degree angle of the DIMM socket mountings it is
physically easier to populate DIMMs starting with DIMM0 and moving towards DIMM3.
Memory size can vary between sockets and slot vacancy between DIMMs is permitted. Mixing
of DIMM size is allowed as long as they are all registered DIMMs. For a list of compatible tested
memory please visit the support site at support.intel.com.
The serverboard supports the following memory features:
168-pin SPD DIMMs with gold-plated contacts.
133 MHz and 100 MHz registered SDRAM DIMMs, 72-bit ECC, 3.3V memory.
Single- or double-sided DIMMs in the sizes listed in Table 16.
Registered DIMMs of the following sizes: 64M, 128M, 256M, 512M and 1G for a
maximum memory size of 4 GB. Double stacked DIMMs may only be used if they
are within the 4.33 mm maximum thickness imposed by the 25 degree DIMM socket
spacing on the baseboard.
