A9739A is the 32-DIMM memory carrier board for the 4U HP Integrity rx4640. It supports from 4 to 32 DIMMs, which is 1 to 128 GB, at 12.8-GB/s memory bandwidth. It is the board that holds the rx4640 maximum of 128 GB, made of eight 16-GB quads.
A9738A, the other carrier board, takes 4 to 16 DIMMs (1 to 64 GB). Both boards provide the same bandwidth to the processors; the primary difference between them is total memory capacity.
The spare boards for A9739A are A9739-69003, a 32-slot memory board PCA, and A7124-69001, an exchange 32-slot memory board PCA. A9739-69006 is a 32-slot memory board carrier PCA. A9739-69007 and A9739-69008 are 32-slot memory carrier boards for firmware versions greater than 1.13.
DIMMs are installed in quads of four equal-density DIMMs, in the order depicted on the board, with the largest-capacity quads in the lowest-numbered slots. Quads for the rx4640 are 1 GB, 2 GB, 4 GB, 8 GB or 16 GB.
