AB475A is a 16-GB chip spare PC2100 DDR-SDRAM memory quad of four 4GB DIMMs, for the HP Integrity rx2620 and the HP Integrity rx4640. HP calls it the rx4640 16GB DIMMs DDR-SDRAM quad memory. The spare is AB475-69001, a 4.0GB DDR-SDRAM module that carries an 8-slot restriction on the rp34x0 and the rx2620.
In the rx2620 the 4-GB DIMMs are the top density: the server has twelve DIMM slots and its maximum is 32 GB, eight 4-GB DIMMs. A quad is four equal-density DIMMs. In the rx4640, memory goes in quads of equal-density DIMMs too, the minimum is 1 GB, and the maximum is 128 GB, using eight 16-GB quads in the memory carrier board A9739A. The quads with the largest capacity belong in the lowest-numbered slots.
The rx4640 memory carrier board A9738A takes 4 to 16 DIMMs (1 to 64 GB) and A9739A takes 4 to 32 DIMMs (1 to 128 GB), both at 12.8-GB/s memory bandwidth. The 8-GB quad for the rx4640 is A6970A.
