A7129A is the 2 GB DDR-SDRAM memory upgrade kit made of four 512 MB, 266 MHz, PC2100 DIMMs, for the HP 9000 rp4410 and HP 9000 rp4440. The 512 MB DIMM spare is A6968AX. The rp4440-8 uses the same 2 GB DDR quad.
It sits second in the quad range: A7128A is 1 GB, A7130A is 4 GB, A7131A is 8 GB and AB560A is 16 GB. The minimum memory for the server is one 1 GB quad.
A quad is four DIMMs, and all four are the same density. Follow the order depicted on the memory carrier board when loading, with the quads of largest capacity in the lowest numbered slots. The carrier board is either A9738B or A9739B: the first takes 4 to 16 DIMMs for 1 to 64 GB, the second takes 4 to 32 DIMMs for 1 to 128 GB, and each delivers 12.8 GB/s.
Eight 16 GB quads on A9739B set the 128 GB ceiling. The smaller carrier board holds up to four quads.
