A7131A is the HP 8 GB DDR quad for the HP 9000 rp4410 and HP 9000 rp4440, including four 2.0 GB, 266 MHz, PC2100 DDR-SDRAM DIMMs. The 2 GB DIMM spares are A6970AX and A6835-69001, a registered DDR SDRAM module. The rp4440-8 uses the same 8 GB DDR quad.
It is the second-largest quad. A7128A (1 GB), A7129A (2 GB) and A7130A (4 GB) are smaller, and AB560A is the 16 GB quad of four 4 GB DIMMs.
DIMMs are installed four at a time, and a quad cannot mix densities. Quads load in the sequence marked on the memory carrier board, with the biggest capacities in the lowest numbered slots. The two carrier boards are A9738B (4 to 16 DIMMs, 1 to 64 GB) and A9739B (4 to 32 DIMMs, 1 to 128 GB), and either provides 12.8 GB/s of memory bandwidth.
On carrier board A9739B the server reaches 128 GB with eight 16 GB quads.
