What the Xeon E7440 is

The Intel Xeon E7440 is a 2.4 GHz multiprocessor quad core from September 15, 2008. It runs four Core cores at 2.4 GHz with no turbo, so 4 cores give 4 threads. Cache is 6 MB of L2 with a large shared 16 MB L3 on a 45 nm process. Power is rated at 90 W on Socket 604.

Dunnington packs Core dies with a shared L3 for up to four-socket Caneland servers on a 1066 MT/s bus, with SSE4 and SpeedStep. The E7440 exists because database servers wanted the biggest L3 per quad core without moving to six cores.

Socket and motherboard compatibility

The E7440 fits Socket 604 Caneland multiprocessor boards with DDR2 memory and a BIOS that lists Dunnington parts. It scales to multi-socket machines per the board design. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Memory, PCIe and cooling

Memory is DDR2 through the Caneland 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 with threaded backplates for the 90 W envelope.

Upgrade paths

On Socket 604 the upgrade is the Intel Xeon E7458 at 2.4 GHz with six cores and 16 MB of L3, or the Intel Xeon E7430 at 2.133 GHz for a cheaper quad. The Intel Xeon E7450 at 2.4 GHz is the six-core 12 MB option. Beyond Socket 604 a move to a newer Xeon platform needs new boards and memory.
