What the Xeon E3-1230 v5 is
The Xeon E3-1230 v5 is a mainstream headless Skylake workstation part on LGA 1151 for single socket servers. Intel set 4 cores and 8 threads at 3.4 GHz base with turbo to 3.8 GHz. Eight megabytes of Smart Cache cover builds. Power is 80 W on 14 nm from October 2015. No integrated graphics exist.
Balanced clocks with 8 threads suit virtualization hosts with BMC graphics. Turbo handles bursts while all core work holds base. The 80 W envelope fits rack workstations with standard cooling. ECC over two channels protects tenants.
DDR4 and DDR3L ECC to 64 GB feed the node. Buyers pick the 1230 v5 where mainstream headless threads with ECC must fit C236 at volume pricing.
Socket and motherboard compatibility
The 1230 v5 fits LGA 1151 on C236 workstation boards. The socket C236 table covers Skylake-DT. Volume firmware carries this popular stepping. Consumer boards lack E3 support.
ECC UDIMMs to 64 GB populate two channels. LGA 1150 never accepts Skylake. BMC graphics cover setup.
Memory, PCIe and cooling
DDR4-1866 and 2133 ECC over two channels to 64 GB suit mainstream hosts. DDR3L ECC suits reuse. Bandwidth covers 8 threads well.
PCIe 3.0 with 16 lanes from the CPU serves NICs and NVMe. Hosts use lanes for I/O rather than graphics. A 10 GbE NIC suits cluster traffic.
Cooling uses 80 W rack or tower sinks. All core turbo needs airflow. No boxed cooler ships.
Upgrade paths
On the same socket the Intel Xeon E3-1240 v5 at 3.5 GHz base above adds clocks for more money, while the Intel Xeon E3-1220 v5 at 4 threads below saves cost. All share C236 boards where listed.
A move to E3 v6 needs Kaby Lake-DT firmware. The 1230 v5 holds mainstream headless volume in Skylake workstations.
