AB526A is a two-core 800 MHz PA 8900 processor module for the HP 9000 rp4410. The module carries 3 MB of Level 1 cache (1.5 MB per core) and 64 MB of Level 2 cache shared between the two cores, and a floating-point coprocessor is included.
Three spare numbers cover this module: AB526-69001, AB526-69002 and AD059-69001. Each is a dual core CPU assembly with an 800 MHz PA8900 CPU and 64 MB of L2 cache, and each needs PDC greater than 44.21.
The rp4410 base system A9955A is built with one active and one inactive 800 MHz core, and the second core cannot be used until the AB524A activation is added. The activation has to be in place before a second two core PA 8900 processor goes in. The server takes one or two processor modules, up to four cores, and modules go in one at a time with cores filled in the sequence 0, 1, 2, 3. 800 MHz and 1.0 GHz processors or cores cannot be mixed in the same system.
The PA 8900 has single bit cache error correction, 44-bit physical addressing and 64-bit virtual addressing.
