Intel Xeon X5650 2.66GHz LGA 1366 processor

This Intel Xeon X5650 server processor operates at 2.66GHz on the LGA 1366 socket. It features six cores with 1.5MB of L2 cache and 12MB of L3 cache. The unit is supplied without a cooling device. It is intended for compatible server and workstation platforms.

Suits LGA 1366 servers needing six cores

This processor suits administrators upgrading or repairing LGA 1366 server systems that require six cores at 2.66GHz. It is not for buyers who need a different socket, a higher core count, an integrated cooler, or a newer processor generation.

LGA 1366 socket with 3200MHz bus speed

The decisive specification is the LGA 1366 socket paired with a 3200MHz bus speed. Only motherboards designed for this exact socket and bus combination will accept the part. Verify the platform supports these two values before purchase.

Questions about this item

How does the 2.66 GHz clock speed perform in a real server workload?

The six-core Xeon runs at 2.66 GHz base frequency, delivering steady multi-threaded throughput for virtualisation and database tasks.

What does the 3200 MHz system bus mean for memory bandwidth?

The 3200 MHz QPI link connects the processor to the chipset, capping peak inter-socket and memory-controller bandwidth at that rate.

Will this processor fit a standard LGA 1366 motherboard?

Yes, it uses the LGA 1366 socket (Socket B) and requires a compatible server board with appropriate power delivery.
