DDR2 ECC REGISTERED FB-DIMM MEMORY
Use only fully-buffered, PC2-5300F DIMMS (FB-DIMMs). Match DIMMs by size and type. With the exception of the single-
DIMM configuration, all memory should be added in like pairs. Use HP memory only.

If using only one DIMM, install in socket 1 (bottom DIMM slot when rear inputs/outputs of motherboard are facing left). If
using 2 DIMMs, install in sockets 1 & 5, matched by size and type. If using more than 2 DIMMs, pairs must be matched by
size and type in sockets 1 and 3, 5 and 7, 2 and 4, and 6 and 8; this may require moving the DIMM in socket 5 to socket 3.
If using 8 DIMMs, install in all sockets.

MAXIMUM MEMORY

Supports up to 128 GB of DDR2 Fully Buffered DIMMs . Memory risers are required to support larger memory configurations
(at launch, Configure-to-order HP xw8600 Workstations ordered with more than 16 GB of memory will require riser
modules). Large capacity 8 GB DIMMs require the use of riser cards. No quad ranked DIMM should be used in the HP
xw8600 without riser cards.
