Add-On Memory
To locate the HP part number, look at the HP Security/CT Label located on the DIMM.
AD275A (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 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
The HP Integrity rx2660 servers require system firmware version 03.01 or later to support the
following Memory Add-On products:
• AD274A 2 GB DDR2 Memory Pair (2 x 1 GB DIMMs)
• AD275A 4 GB DDR2 Memory Pair (2 x 2 GB DIMMs)
• AD276A 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
