What Is a Processor Carrier on an Intel® Xeon® Processor?

What is a Carrier?

Carriers are needed to properly align and install the CPU onto the motherboard. Intel® Xeon® W processor families each have their own required carriers.

Carrier Features

• Visual Indicators: Carriers and CPUs are marked with carrier codes (E1A, E1B) to indicate which should be used.
• Keying Features: Carriers are keyed, mitigating the mixing of carriers with CPU or installing in the wrong orientation.
• Integrated Shims: E1B carriers for Intel Xeon W processors have integrated shims that ensure proper CPU to socket loading is provided by the bolster plate.
