A7128A is the HP 1 GB DDR memory quad for the HP 9000 rp4410 and HP 9000 rp4440, four 256 MB DIMMs. The 1.0 GB DDR-SDRAM upgrade kit uses 256 MB, 266 MHz, PC2100 modules, and the DIMM spare is A6967AX. The rp4440-8 uses the same 1 GB DDR quad.
At 1 GB, A7128A is the smallest quad and also the minimum memory for the server. The other quads are A7129A (2 GB), A7130A (4 GB), A7131A (8 GB) and AB560A (16 GB of 4x4 GB DIMMs).
Memory goes in sets of four DIMMs, and each quad has to be made of DIMMs with the same density. The quads load in the order marked on the memory carrier board, and the quads with the largest capacity belong in the lowest numbered slots. The server is ordered with one of two carrier boards, A9738B (4 to 16 DIMMs, 1 to 64 GB) and A9739B (4 to 32 DIMMs, 1 to 128 GB), and both provide 12.8 GB/s of memory bandwidth.
The server memory maximum is 128 GB, reached with eight 16 GB quads on carrier board A9739B. The memory is DDR SDRAM with chip spare protection.
