Table 4 Server Blade Memory Array Capacities (continued)
Single DIMM SizesMin / Max Memory Size
2 GB4 GB / 24 GB
4 GB8 GB / 48 GB
NOTE: Installing DIMMs as a pair (two identical DIMMs) enables lock-step mode and chip
sparing.
Install DIMMs from highest capacity to lowest capacity (for example, install the 4-GB DIMMs first,
then the 2-GB DIMMs, then the 1-GB DIMMs, and so forth).
For more information, see “Removing and Replacing DIMMs” (page 114).
Add-On Memory
To locate the HP part number, look at the HP Security/CT Label located on the DIMM.
AD344A (2 x 2 GB DIMMs) memory with the HP part number AB565DX cannot be mixed on the
same physical rank as 2 GB memory with the AB565CX, AB565BX, or AB565AX HP part number.
IMPORTANT: Earlier versions of system firmware do not support the installation of this replacement
memory and can result in de-allocation of the entire quad or pair.
Firmware Updates
HP Integrity BL860c server blades require system firmware version 03.02 or later to support the
following Memory Add-On products:
• AD343A 2 GB DDR2 Memory Pair (2 x 1 GB DIMMs)
• AD344A 4 GB DDR2 Memory Pair (2 x 2 GB DIMMs)
• AD345A 8 GB DDR2 Memory Pair (2 x 4 GB DIMMs)
Before installing any of these memory products, verify the server firmware version is equal to or
higher than the version listed above for your product. On HP Integrity servers, you can determine
the firmware version using the following EFI Shell info fw command:
Shell> info fw
