Memory

Each LC5518 processor has an IMC, which can support up to four DDR3 memory channels. Generally, a dual-socket LC5518 design can support up to six DDR3 channels, three from each processor’s IMC. The blade server uses four of the six channels with two DDR3 DIMM slots per channel operating at 1066MHz.

The blade server can support 4 GB DDR3 memory modules for configurations of 16 GB and 32 GB total memory. Each memory channel has two slots: 0 and 1, as shown on the AMC faceplate. When using only four DIMMS, they must all be installed in slots 0 and filler panels must be installed in corresponding slots 1.

Additional features of the blade server’s memory architecture include:

• Very low-profile (0.72-inch) DIMM support

• Memory bandwidth up to 8.5 Gbyte per second per channel, with a 34 Gbyte per second total memory bandwidth

• DDR3 power requirements 4.4W to 7.0W (1.8V)

• The blade server supports the BIOS implementation of PMEM.
