What the Opteron 148 is
The AMD Opteron 148 is a 2.2 GHz single-core server processor from August 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 85 W on Socket 939.
The 148 served single-processor Venus servers with unbuffered DDR memory on a 1000 MT/s HyperTransport link. It exists because entry servers wanted a 2.2 GHz Venus single core above the 146.
Socket and motherboard compatibility
The 148 fits Socket 939 single-processor server boards with a BIOS that lists Venus parts. It suits entry 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 85 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 150 at 2.4 GHz with the same 1 MB cache, or the AMD Opteron 144 at 1.8 GHz for a lower cost. Beyond Socket 939 a move to Socket AM2 or F needs a new board and memory.
