What the Opteron X2 885 is

The AMD Opteron X2 885 is a 2.6 GHz dual-core server processor from March 2006. It runs two K8 cores at 2.6 GHz with no turbo, so 2 cores give 2 threads. Cache is 1 MB of L2 per core on a 90 nm process. Power is rated at 95 W on Socket 940.

The 885 served performance Egypt servers on a 1000 MT/s HyperTransport link at about 2149 dollars launch price. It exists because multi-socket buyers wanted 2.6 GHz throughput with the full cache at the standard 95 W.

Socket and motherboard compatibility

The X2 885 fits Socket 940 multi-socket server boards with a BIOS that lists Egypt dual cores. It suits performance racks qualified for 95 W parts. Check the server maker CPU list for the exact board and stepping. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Memory, PCIe and cooling

Memory is registered DDR through the on-chip controller.

HyperTransport at 1000 MT/s links the CPU to the chipset and other sockets. PCIe slots hang off the chipset.

Cooling uses vendor qualified server heatsinks for the 95 W envelope with directed airflow.

Upgrade paths

On Socket 940 the upgrade is the Opteron X2 890 at 2.8 GHz with the same cache at 95 W, or the AMD Opteron X2 875 HE at 2.2 GHz for 55 W operation. Beyond Socket 940 a move to Socket F needs new boards and DDR2 memory.
