SR3X9, Intel® Pentium® Gold G5400 Processor (4M Cache, 3.70 GHz) FC-LGA14C CPU. Shipped with USPS First Class Package. I purchased a new computer and upgraded the processor myself when it arrived. This OEM processor was never used by me. I do not know if Lenovo used it when the computer was built. It is under 3 year warranty. I will ship it in the retail box for the i5 processor I upgraded to, so it will be packaged securely. Please note the labels on the box will say i5 processor, but the contents will be the Pentium Gold G5400 in the photos. Photos are the exact processor you will receive.
