What types of CPUs are compatible with the ASRock Rack EPC612D4U motherboard?

The motherboard supports Intel Xeon processor E5-1600 / 2600 v3 / v4 series processors.

What is the maximum memory capacity supported by the ASRock Rack EPC612D4U motherboard?

The maximum memory supported is 128GB for RDIMM (32GB per DIMM) and 256GB for LRDIMM (64GB per DIMM).

Does this systemboard support ECC memory?

Yes.. Additionally, everything on the qvl is rdimm or lrdimm ecc, so this may *require* ecc. Fwiw, the manual says double sided 1gb dimms may not work. Since this is a quad channel board, 4 identical dimms are required for best performance. It will work in 2 channel mode (with reduced performance) using slots A and C.

Manufacturer Contact Info

The ASRock Rack EPC612D4U is a Micro-ATX server motherboard for Intel Xeon E5-1600/2600 v3 and v4 processors, suited to server builders who need remote management through IPMI 2.0 with KVM and a dedicated management LAN. Xeon v4 processors require BIOS version 2.0 or later.

Recommended For

Homelab builders running Proxmox or other virtual machines on a Xeon E5 v3/v4 platform; an owner build using this exact board identifies it as a Proxmox VE VM host.
Self-builders who want server-style remote administration for a headless system or a machine kept away from a desk; the board includes IPMI 2.0 with KVM and a dedicated management LAN.
NAS or storage-server builders using a compatible Xeon E5 processor who need multiple onboard SATA connections; the board provides eight SATA 6 Gb/s ports.
Builders reusing or sourcing compatible LGA 2011-3 Xeon E5 v3/v4 components for a compact server; this is a 9.6-inch-square Micro-ATX board with four registered-memory DIMM slots.
