AT105A HPE Integrity rx2800 i4 Itanium 9540 Processor Kit

AT105A is an Intel Itanium 9540 processor kit for the HPE Integrity rx2800 i4: 2.13 GHz, 8 cores, 24 MB of Level 3 cache and 170 W. The spare processor number is AT085-69025, a 2.13 GHz, 24 MB, 170 W, 8 core processor.

AH395-67004 is the spare latch-type heat sink assembly. It comes with the two locking tabs and the top latch, and the assembly must be replaced when a new processor is installed.

The rx2800 i4 takes up to two processors of the Itanium 9500 series, and processor frequencies cannot be mixed in a server. The 9540 is one of two eight core choices, the other being the 2.53 GHz 9560 in AT106A, and the four core kits are AT104A and AT138A. Each processor supports 12 DDR3 DIMMs, and the server takes up to four 6-slot memory risers with 24 DDR3 registered low voltage DIMMs in total.

Cache per core is 32 KB at Level 1 (16 KB instruction, 16 KB data) and 512 KB instruction plus 256 KB data at Level 2. Other processor features include Turbo Boost Technology, Dynamic Processor resilience and de-allocation, Intel Instruction Replay Technology and Enhanced Intel Hyper Threading with Dual-Domain Multi-Threading support.
