Frequently Asked Questions

What is the difference between CM8066002733700 and SR2KE?

CM8066002733700 is the OEM ordering code while SR2KE is the S-Spec identifier. Both refer to the same Intel Xeon E5-2673 v4 processor.

Why is the E5-2673 v4 so affordable?

The E5-2673 v4 was originally deployed in Microsoft Azure cloud data centers. As Azure decommissions older hardware these processors become available on the secondary market at significantly reduced prices.

Does the E5-2673 v4 support ECC memory?

Yes the Xeon E5-2673 v4 supports DDR4 ECC RDIMM and LRDIMM memory up to 4 channels per socket.

The Intel Xeon E5-2673 v4 (CM8066002733700) delivers 20 cores at 2.30GHz with 50MB L3 cache on LGA2011-3 — the OEM ordering code variant of this cost-effective Broadwell-EP processor widely available from Azure cloud decommissions for homelab workstation and budget server deployments.
