AH412A is a 128 GB memory bundle for the HP Integrity rx7640 and HP Integrity rx8640, equal to 8 of the 16 GB memory module AB456A. The DIMMs are the 8192 MB size, and the bundle consists of DIMMs already qualified in that memory module.
Every DIMM carries DDR II memory chips with full ECC protection, and DIMM pairs go in slot order on each cell board. A cell board takes up to 16 DIMM slots, and when sizes are mixed the larger DIMMs are loaded first across the cell. A server using 8192 MB DIMMs alone tops out at 256 GB on the rx7640 and 512 GB on the rx8640.
The 4096 MB version of a 128 GB bundle is AH411A, equal to 16 of AB455A. The spare DIMMs tied to AH412A are AB456-67001, AB456-69001 and AB456-69301, each an 8 GB memory DIMM, and the product is single-rank registered DDR2-533 (PC2-4200).
