What the Xeon 7140N is
The Intel Xeon 7140N is a 3.333 GHz multiprocessor dual-core server processor from August 2006. It runs two NetBurst cores at 3.333 GHz with Hyper-Threading on both cores, so 2 cores give 4 threads. Cache is 2 MB of L2 plus 16 MB of shared L3 on a 65 nm process. Power is rated at 150 W on Socket 604.
The 7140N served performance Tulsa servers with a 667 MT/s bus and a 20x multiplier at about 1980 dollars launch price. The N suffix marks the 667 MT/s bus against 800 MT/s M versions. It exists because multiprocessor buyers wanted high clocks with the largest shared L3 where the chassis cools 150 W.
Socket and motherboard compatibility
The 7140N fits Socket 604 multiprocessor server boards with a BIOS that lists Tulsa parts. It suits quad-processor chassis qualified for 150 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 667 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 multiprocessor chassis with directed airflow.
Upgrade paths
On Socket 604 the upgrade is the Intel Xeon 7150N at 3.5 GHz with the same 16 MB of L3, or the Intel Xeon 7130N at 3.166 GHz with 8 MB. Beyond Socket 604 a move to a newer Xeon platform needs new boards and memory.
