A9738A is the 16-DIMM memory carrier board for the 4U HP Integrity rx4640. It supports from 4 to 16 DIMMs, which is 1 to 64 GB, with 12.8-GB/s memory bandwidth. HP calls it the 16 DIMM memory carrier board for the 4U chassis.
The rx4640 is ordered with one of two memory carrier boards. The other one is A9739A, for 4 to 32 DIMMs (1 to 128 GB), and both boards provide the processors the same bandwidth, so the primary difference between the two is total memory capacity.
The spare boards for A9738A are A6961-69104, a 16-slot memory board PCA, and A6961-69204 and A6961-69804, each a 16-slot memory carrier board.
Memory in the rx4640 is installed in sets of four DIMMs, called quads, of equal density, and loaded in the order depicted on the carrier board. The quads with the largest capacity belong in the lowest-numbered slots. The quad options are A6967A, A6968A, A6969A, A6970A and AB475A, from 1 GB to 16 GB.
