3.3 Memory
Subsystem
All models support non-ECC DDR3-800 (PC3-6400), DDR3-1066 (PC3-8500), and
DDR3-1333 (PC3-10600) memory modules. These systems 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.

Memory modules do not need to be installed in pairs although installation of pairs (especially
matched sets) provides the best performance. Black sockets must be populated first. 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.
