This Intel Xeon Gold 5423N runs 20 cores at 2.10GHz (up to 4.00GHz on boost), with 37.5MB of cache in a 145W power envelope. Part of the 4th Generation Intel Xeon Scalable Processors line, it uses its platform socket and addresses up to 4TB of memory at 4800MHz DDR5.
A Gold-tier chip suits mainstream virtualisation and database hosts. In a two-socket server both processors must be the same model; check the server's supported processor list, BIOS level and heatsink rating for a 145W part before fitting. In most dual-socket servers the second processor also brings its own memory channels and expansion lanes into play. Its S-spec, SRMQQ, pins down the exact stepping. Apply fresh thermal paste each time the processor is seated. A 145W processor needs a heatsink rated for its power, and higher-TDP parts may need the server’s high-performance heatsink. With simultaneous multithreading enabled, it presents 40 threads to the operating system.
As a certified refurbished part, it is inspected, bench-tested and function-checked by our Johannesburg team before release.
