Frequently Asked Questions

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 making them popular for homelab and budget server builds.

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.

Is this compatible with consumer X99 motherboards?

Yes the E5-2673 v4 is compatible with LGA2011-3 consumer X99 motherboards with appropriate BIOS updates though ECC memory support depends on the motherboard.

The Intel Xeon E5-2673 v4 delivers 20 cores at 2.30GHz with 50MB L3 cache on LGA2011-3 — a cost-effective high-core-count Broadwell-EP processor widely available from Azure cloud decommissions for homelab workstation and budget server deployments.
