HPE Xeon X5675 3.06 GHz six-core processor upgrade

This refurbished HPE processor upgrade adds a six-core Intel Xeon X5675 running at 3.06 GHz to compatible servers. It uses the LGA-1366 socket and draws 95 W TDP with a maximum turbo frequency of 3.46 GHz. The part is aimed at administrators refreshing or repairing HPE ProLiant BL460c G7 systems.

Who this suits and who should look elsewhere

It fits technicians maintaining or upgrading BL460c G7 servers that require the 5600-series Xeon in an LGA-1366 package. Buyers needing a different socket, a higher core count, or a newer microarchitecture cannot use this part. It is also unsuitable for desktop or workstation boards that lack the specific server-qualified BIOS support.

Deciding specification — LGA-1366 socket

The processor only installs in a Socket B LGA-1366 motherboard with validated firmware for the Xeon 5600 series. Verify the server model and BIOS revision before purchase because the part will not function in any other socket or platform.

What server socket does the X5675 processor fit?

The processor installs in a Socket B LGA-1366 socket on the system board.

How is the processor upgrade installed, and what step is often missed?

Align the notches, seat the chip in the LGA-1366 socket, close the load lever, then apply thermal paste before attaching the heatsink.

When should the thermal interface material be replaced on this 95 W Xeon?

Replace the thermal paste whenever the heatsink is removed or if temperatures approach the 81.3 °C thermal specification.
