What the Xeon 5160 is
The Intel Xeon 5160 is a 3 GHz dual-core server processor from June 2006. It runs two Core cores at 3 GHz with no turbo, so 2 cores give 2 threads. Cache is 4 MB of shared L2 on a 65 nm process. Power is rated at 80 W on Socket 771.
The 5160 topped the Woodcrest 5100 line on a 1333 MT/s bus with a 9x multiplier at about 851 dollars launch price. It exists because performance servers wanted 3 GHz Core throughput with the full 4 MB cache where the chassis cools 80 W.
Socket and motherboard compatibility
The 5160 fits dual-socket Socket 771 server boards with a BIOS that lists 1333 MT/s performance Woodcrest parts. It suits performance racks qualified for 80 W dual cores. 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 FB-DIMMs through the server board chipset.
A 1333 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 80 W envelope in racks with directed airflow.
Upgrade paths
On Socket 771 the upgrade is Clovertown quads such as the 2.667 GHz X5355 for four cores, or the Intel Xeon 5150 at 2.667 GHz for a lower cost dual core. Beyond Socket 771 a move to a newer Xeon platform needs new boards and memory.
