IBM 59Y4026 Xeon X5667 3.06 GHz processor upgrade

SKU CH-NHEE-5SRDZ MPN 59Y4026

A quad-core Xeon processor upgrade running at 3.06 GHz with 12 MB L3 cache for Socket B LGA-1366 systems

  • Plug typeProcessor Upgrade
  • Quad-core design enables parallel workloads with four cores
  • 06 GHz clock speed delivers responsive compute performance
  • 12 MB L3 cache reduces latency for frequent data
  • 95 W TDP balances power draw and thermal output
  • LGA-1366 socket fits compatible server and workstation boards

Lenovo Xeon X5667 3.06 GHz Upgrade

This Lenovo Xeon X5667 processor upgrade delivers four cores at 3.06 GHz with a 12 MB L3 cache for 1-way or 2-way servers and workstations. It uses a Socket B LGA-1366 interface and runs on a 32 nm process with 95 W thermal design power.

Suits LGA-1366 Quad-Core Upgrades

This part suits administrators upgrading compatible Lenovo or IBM systems that accept a Socket B LGA-1366 processor with a 95 W envelope. It is not for platforms that require a different socket, a lower power limit, or a higher core count than four.

Socket B LGA-1366 Compatibility Decides Fit

The processor fits only motherboards with a Socket B LGA-1366 socket and a thermal design power budget of 95 W. Verify the system board supports this specific model before purchase.

Questions about this item

How do I install the Xeon X5667 into the Socket B LGA-1366, and what step do people often miss?

Align the notches, lower the processor gently, and close the load plate before locking the lever; the step often missed is applying fresh thermal paste to the 95 W heat spreader.

What maintenance or replacement will the Xeon X5667 need over time?

Plan to replace the thermal interface material every few years and verify the heatsink fan runs cleanly so the 74 °C thermal specification is not exceeded.

What limit appears first when the Xeon X5667 runs at full load for long periods?

The 95 W thermal design power and 74 °C case temperature ceiling are reached before the 6.40 GT/s QuickPath Interconnect saturates.
