What the Xeon E3-1220 v5 is
The Xeon E3-1220 v5 opens the Skylake workstation line on LGA 1151 for entry servers. Intel set 4 cores and 4 threads at 3.0 GHz base with turbo to 3.5 GHz. Eight megabytes of Smart Cache cover infrastructure services. Power is 80 W on 14 nm from October 2015. Hyper-Threading is off and no integrated graphics exist.
Four plain cores suit firewall and storage duty with ECC protection. Fixed thread behavior simplifies small hosts. Turbo covers bursts while steady serving holds base. The 80 W envelope with entry pricing fits branch servers.
DDR4 and DDR3L ECC over two channels to 64 GB feed the node. ECC guards always on data. Buyers pick the 1220 v5 where entry workstation threads with ECC must cost the least on C236.
Socket and motherboard compatibility
The 1220 v5 fits LGA 1151 on C236 workstation boards. The socket C236 table covers Skylake-DT. Entry firmware carries the 4 thread stepping. Consumer boards lack E3 validation.
ECC UDIMMs to 64 GB are standard. LGA 1150 never boots Skylake. A BMC card covers setup without an iGPU.
Memory, PCIe and cooling
DDR4-1866 and 2133 ECC over two channels to 64 GB suit entry hosts. DDR3L ECC covers reuse. Simple thread counts need modest bandwidth.
PCIe 3.0 with 16 lanes from the CPU serves NICs and storage. Entry nodes use lanes for network expansion. A basic NIC suits branch traffic.
Cooling uses 80 W tower or rack sinks. Steady 3.0 GHz base loads need airflow. No boxed cooler ships.
Upgrade paths
On the same socket the Intel Xeon E3-1230 v5 at 3.4 GHz to 3.8 GHz with 8 threads above doubles threads for more money, while the Intel Xeon E3-1225 v5 at 3.3 GHz to 3.7 GHz adds P530 graphics. All share C236 boards where listed.
A move to E3 v6 needs new firmware. The 1220 v5 holds entry 4 thread duty in Skylake workstations.
