Server processor for LGA 771 platforms

This is an Intel Xeon E5-2650L v2 processor with ten cores and twenty threads running at a base frequency of 1.7 GHz. It carries 25 MB of L3 cache and operates within a 70 W thermal envelope. The part is supplied as a bare processor without a cooling device. It is intended for server motherboards that accept the LGA 771 socket.

Suited for density-focused server upgrades

The processor fits administrators refreshing LGA 771 servers where power budget and core density matter more than single-thread speed. Buyers needing higher clock rates or newer instruction sets should look elsewhere. The component is not compatible with desktop or workstation boards that use different socket types.

LGA 771 socket requirement

Installation is only possible on a server motherboard equipped with an LGA 771 socket. No cooler is included so a compatible heatsink must be sourced separately. Verify the system board supports this specific Xeon model before purchase.

Questions about this item

What socket and power budget must the server board provide for the 10-core 1.7 GHz Xeon?

The processor fits an LGA 771 socket and has a 70 W thermal design power, so the motherboard must support that socket and supply adequate cooling for 70 W.

Which installation step is most often missed when fitting this bare processor into a server?

Because no cooling device is included, the critical step is mounting a compatible LGA 771 heatsink with correct pressure and thermal paste before powering on.

What component will need replacement first if the server runs continuously under load?

The separate heatsink fan is the only moving part; plan to replace it when bearing noise appears or airflow drops below the 70 W cooling requirement.
