What the Xeon E3-1283L v4 is
The Xeon E3-1283L v4 is a headless Broadwell workstation part on LGA 1150 for dense servers. Intel set 4 cores and 8 threads at 2.9 GHz base with turbo to 3.8 GHz. Six megabytes of Smart Cache plus 128 MB of eDRAM as L4 cover server loads. Power is 47 W on 14 nm from June 2015. No integrated graphics exist.
High clocks at 47 W suit single socket micro servers with BMC graphics. Turbo to 3.8 GHz leads the low power E3 v4 line. The eDRAM serves as L4 cache for the cores. Eight threads handle virtualized infrastructure services.
DDR3 ECC over two channels to 32 GB feeds the node. ECC is required. Buyers pick the 1283L v4 where headless speed with low power must fit a C226 board.
Socket and motherboard compatibility
The 1283L v4 fits LGA 1150 on C226 workstation boards. Consumer boards lack ECC validation, so use C226 despite the shared socket. The C226 chipset table on the socket page covers this codename.
ECC UDIMMs populate two channels. LGA 1151 never accepts Broadwell silicon. Check the board list for the L suffix thermal profile.
Memory, PCIe and cooling
DDR3-1866 ECC over two channels to 32 GB suits micro servers. Dual channel pairs protect bandwidth. ECC guards hypervisor memory.
PCIe 3.0 with 16 lanes from the CPU serves NICs and NVMe. Headless nodes use BMC graphics for setup. A 10 GbE card suits cluster traffic.
Cooling uses 47 W 1U heatsinks with server airflow. No boxed cooler ships. High base clocks need cool inlets.
Upgrade paths
On the same socket the Intel Xeon E3-1270L v4 at 3.0 GHz to 3.6 GHz nearby trades turbo for similar power, while the Intel Xeon E3-1285L v4 adds Iris Pro graphics for media work. All share C226 boards where listed.
A move to E3 v5 needs C236. The 1283L v4 covers headless speed in Broadwell workstations.
