What the Opteron 154 is
The AMD Opteron 154 is a 2.8 GHz single-core server processor from August 2005. It runs one K8 core at 2.8 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 104 W on Socket 939.
The 154 served performance single-processor Venus servers with unbuffered DDR memory on a 1000 MT/s HyperTransport link. It exists because entry servers wanted a 2.8 GHz Venus single core with the full 1 MB cache.
Socket and motherboard compatibility
The 154 fits Socket 939 single-processor server boards with a BIOS that lists Venus parts. It suits performance builds with unbuffered DDR slots. Check the board maker CPU list for the exact stepping. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is unbuffered DDR in two channels through the on-chip controller.
HyperTransport at 1000 MT/s links the CPU to the chipset. PCIe or AGP slots hang off the chipset.
Cooling is any 104 W rated Socket 939 heatsink on the AMD retention frame, with CoolnQuiet trimming draw at idle.
Upgrade paths
On Socket 939 the upgrade is the Opteron 156 at 3 GHz with the same 1 MB cache, or the AMD Opteron 152 at 2.6 GHz for a lower cost. Beyond Socket 939 a move to Socket AM2 or F needs a new board and memory.
