Intel Xeon E7340 socket: Socket 604

What the Xeon E7340 is

The Intel Xeon E7340 is a 2.4 GHz multiprocessor quad core from September 2007. It runs four Core cores at 2.4 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 80 W on Socket 604.

The E7340 balanced clock and cache on a 1066 MT/s bus with a 9x multiplier at about 1980 dollars launch price. It exists because multiprocessor buyers wanted the full 8 MB Tigerton cache at a mid 2.4 GHz clock without the 130 W of the X7350.

Socket and motherboard compatibility

The E7340 fits Socket 604 multiprocessor server boards with a BIOS that lists Tigerton quads. It suits quad-processor chassis qualified for 80 W parts.

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 80 W envelope in multiprocessor chassis with directed airflow.

Upgrade paths

On Socket 604 the upgrade is the Intel Xeon X7350 at 2.933 GHz with the same 8 MB cache where the chassis cools 130 W, or the Intel Xeon E7320 at 2.133 GHz for a lower cost quad. Beyond Socket 604 a move to a newer Xeon platform needs new boards and memory.
