What the Opteron 248 HE is
The AMD Opteron 248 HE is a 2.2 GHz low-power single-core server processor from March 2005. It runs one K8 core at 2.2 GHz with no turbo, so 1 core gives 1 thread. Cache is 1 MB of L2 on a 90 nm process. Power is rated at 55 W on Socket 940.
The 248 HE served dense Troy racks with registered DDR memory on a 1000 MT/s HyperTransport link at about 690 dollars launch price. It exists because dense servers wanted 2.2 GHz throughput with lower power than standard Troy parts.
Socket and motherboard compatibility
The 248 HE fits Socket 940 dual-processor server boards with a BIOS that lists HE Troy parts. It suits dense chassis qualified for 55 W parts with registered DDR slots. 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 in two channels 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 55 W envelope with directed airflow.
Upgrade paths
On Socket 940 the upgrade is the Opteron 250 HE at 2.4 GHz at the same 55 W, or the AMD Opteron 246 HE at 2 GHz for a lower cost. Beyond Socket 940 a move to Socket F needs new boards and DDR2 memory.
