A9732A HP Intel Itanium 2 1.6-GHz 6MB Processor (rx4640)

A9732A is a 1.6-GHz Intel Itanium 2 processor, one core, with 6 MB of level 3 cache, for the HP Integrity rx4640. HP calls it the rx4640 Itanium2 1.6GHz 6MB CPU. Its on-chip cache is 32 KB at level 1, 256 KB at level 2 and 6 MB at level 3, and a floating point coprocessor is included.

Like the other single-core processors of the rx4640, it has single bit cache error correction, 50-bit physical addressing and 64-bit virtual addressing. The processor of the same 1.6-GHz speed with a 9-MB level 3 cache is A9733A.

The rx4640 may require a firmware update before A9732A is installed, since system firmware 3.17 or later is needed. The revision can be checked at the EFI shell with the info fw command, and the release notice in the download bundle holds the upgrade instructions.

The rx4640 takes up to four processors. They can be installed one at a time, in the sequence 0, 1, 2, 3, and they cannot be mixed in the same system.
