A9738B is the HP 16-DIMM memory carrier board. It supports from 4 to 16 DIMMs (1 to 64 GB), which is up to four quads of memory, with 12.8 GB/s of memory bandwidth. The HP 9000 rp4410 and HP 9000 rp4440 can be ordered with this board or with the 32-DIMM board, A9739B.
Both boards provide the same bandwidth to the processors, and the main difference is total memory capacity. The servers hold double data rate SDRAM DIMMs with chip spare protection, installed in quads of equal-density DIMMs in the order depicted on the carrier board, with the largest-capacity quads in the lowest numbered slots.
Quads for the board are A7128A (1 GB), A7129A (2 GB), A7130A (4 GB), A7131A (8 GB) and AB560A (16 GB), and the minimum memory is 1 GB. The largest server configuration is 128 GB, which needs the A9739B board rather than this one.
The spare numbers for this 16-slot board are A6961-69104 (PCA, 16-slot memory board), A6961-69204 (16-slot memory carrier) and A6961-69804 (16-slot memory carrier).
