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.
