IBM 69Y4426 Xeon X5550 2.66 GHz processor upgrade

SKU CH-NWNR-M229P MPN 69Y4426

Quad-core Xeon processor upgrade running at 2.66 GHz with 8 MB L3 cache for Socket B LGA-1366 servers

  • Quad-core design handles parallel workloads efficiently
  • 66 GHz base clock with 3.06 GHz overclocking speed
  • 40 GT/s QuickPath Interconnect accelerates data transfer
  • 45 nm process technology balances performance and power draw
  • 95 W thermal design power fits standard server cooling

Xeon X5550 processor upgrade

This IBM-IMSourcing upgrade supplies a quad-core Intel Xeon X5550 running at 2.66 GHz with a 3.06 GHz turbo frequency. It targets administrators refreshing compatible LGA-1366 servers that need four processing threads for legacy workloads. The 45 nm part includes 1 MB of L2 cache and 8 MB of L3 cache.

QuickPath Interconnect at 6.40 GT/s

The processor communicates over a QuickPath Interconnect link rated at 6.40 GT/s, which sets the practical bandwidth ceiling for memory and I/O traffic in a dual-socket board. Systems that cannot match this link speed will throttle inter-socket data movement. The 95 W thermal design power also defines the cooling envelope the chassis must sustain.

Refurbished LGA-1366 socket processor

The unit is a refurbished OEM processor without a retail heat-sink or fan, so the integrator must supply a compatible LGA-1366 cooler rated for at least 95 W. The 1.4 V DC input voltage is standard for the socket, but the absence of bundled thermal hardware means builders who need a drop-in kit with a guaranteed fan should look elsewhere.
