What the Xeon L7345 is
The Intel Xeon L7345 is a 1.867 GHz low-voltage multiprocessor quad core from September 2007. It runs four Core cores at 1.867 GHz with no turbo, so 4 cores give 4 threads. Cache is 8 MB of L2 as two 4 MB dies on a 65 nm process. Power is rated at 50 W on Socket 604.
The L7345 brought Tigerton quads to power capped servers on a 1066 MT/s bus with a 7x multiplier at about 2301 dollars launch price. It exists because dense multiprocessor racks wanted quad core throughput at low voltage with the same cache as faster quads.
Socket and motherboard compatibility
The L7345 fits Socket 604 multiprocessor server boards with a BIOS that lists low-voltage Tigerton quads. It suits quad-processor chassis qualified for 50 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 DDR2 through the server board chipset.
A 1066 MT/s front side bus ties the CPU to the server chipset. PCIe slots hang off the chipset.
Cooling uses vendor qualified server heatsinks for the 50 W envelope in dense chassis with directed airflow.
Upgrade paths
On Socket 604 the upgrade is the Intel Xeon E7320 at 2.133 GHz with 4 MB of cache at 80 W, or the Intel Xeon E7340 at 2.4 GHz with 8 MB where the chassis cools 80 W. Beyond Socket 604 a move to a newer Xeon platform needs new boards and memory.
