3.3Memory Subsystem

All models support non-ECC DDR3-800 (PC3-6400), DDR3-1066 (PC3-8500), and DDR3-1333 (PC3-10600) memory modules. The USDT form factor supports up to eight gigabytes of memory while the SFF and CMT form factors support up to 16 gigabytes of memory.

In these systems, DDR3-1333 modules operate at the same speed/rate as DDR3-1066 modules.

DDR3 memory modules are not compatible with DDR2 memory modules used on previous systems.

The USDT system board provides two SODIMM sockets and the SFF and CMT system boards provide four DIMM sockets

XMM1, channel A (black)

XMM2, channel A (white, not present in USDT form factor)

XMM3, channel B (white)

XMM4, channel B (white, not present in USDT form factor)

Memory modules do not need to be installed in pairs although installation of pairs (especially matched sets) provides the best performance. The XMM1 socket must be populated for proper support of Intel Active Management Technology (AMT). The BIOS will detect the module population and set the system accordingly as follows:

Single-channel mode - memory installed for one channel only

Dual-channel asymetric mode - memory installed for both channels but of unequal channel capacities.

Dual-channel interleaved mode (recommended) - memory installed for both channels and offering equal channel capacities, proving the highest performance.

These systems support memory modules with the following parameters:

Unbuffered, compatible with SPD rev. 1.0

512-Mb, and 1-Gb memory technologies for x8 and x16 devices

CAS latency (CL) of 5 or 6 (depending on memory speed)

Single or double-sided

Non-ECC memory only

The SPD format supported by these systems complies with the JEDEC specification for 128-byte EEPROMs. This system also provides support for 256-byte EEPROMs to include additional HP-added features such as part number and serial number.

If BIOS detects an unsupported memory module, a “memory incompatible” message will be displayed and the system will halt. These systems are shipped with non-ECC modules only.

An installed mix of memory module types is acceptable but operation will be constrained to the level of the module with the lowest (slowest) performance.

If an incompatible memory module is detected the NUM LOCK will blink for a short period of time during POST and an error message may or may not be displayed before the system hangs.
