What the Xeon X5365 is
The Intel Xeon X5365 is a 3 GHz server quad core from August 2007. It runs four Core cores at 3 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 150 W on Socket 771.
The X5365 led the Clovertown 5300 line on a 1333 MT/s bus with a 9x multiplier at about 1350 dollars launch price. It exists because performance servers wanted the first 3 GHz quad inside a standard power envelope with virtualization extensions.
Socket and motherboard compatibility
The X5365 fits dual-socket Socket 771 server boards with a BIOS that lists Clovertown quads. It suits performance racks qualified for 150 W quads. 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 150 W envelope in racks with directed airflow.
Upgrade paths
On Socket 771 the upgrade is Harpertown such as the 3 GHz X5450 with 12 MB of cache at 120 W, or the Intel Xeon L5335 at 2 GHz for the same Clovertown cache at 50 W. Beyond Socket 771 a move to a newer Xeon platform needs new boards and memory.
