Intel Xeon X5550 2.66 GHz processor

This Intel Xeon X5550 is a quad-core server processor running at 2.66 GHz with a 95 W TDP. It uses the LGA 1366 socket and a 45 nm manufacturing process. The chip includes 1 MB of L2 cache and 8 MB of L3 cache. It suits administrators upgrading compatible dual-socket platforms.

Thermals noise and power in normal use

The 95 W thermal design power defines the cooling requirement for typical workloads. A 6.4 GT/s QPI link moves data between sockets with moderate power draw. The 45 nm process helps contain heat output during sustained operation. Buyers needing lower-power parts or different socket types should look elsewhere.

Highlights

  • Quad-core Xeon handles parallel workloads with four cores
  • 66 GHz clock speed drives responsive compute performance
  • 8 MB L3 cache reduces latency for frequent data access
  • 4 GT/s QPI link enables fast processor-to-processor communication

Questions about this item

How is the Xeon X5550 installed in a Socket B (LGA 1366) board, and what step do people often get wrong?

Align the notches on the processor with the socket keys, lower it straight down without pressure, then close the load plate; the common mistake is forcing the chip before the notches engage, which bends the delicate contacts.

What maintenance or replacement will the Xeon X5550 need later?

The 95 W TDP requires a heatsink rated for at least that load; plan to replace the thermal paste every few years and clean dust from the cooler fins to keep temperatures stable.
