What the Xeon E3-1270L v4 is
The Xeon E3-1270L v4 is a low power headless Broadwell workstation part on LGA 1150. Intel set 4 cores and 8 threads at 3.0 GHz base with turbo to 3.6 GHz. Six megabytes of Smart Cache plus 128 MB of eDRAM as L4 cover server loads. Power is 45 W on 14 nm from June 2015. No integrated graphics exist, so a discrete card or BMC graphics drives displays.
High base clocks at 45 W suit dense micro servers with discrete management graphics. Turbo covers single thread bursts. The eDRAM works as L4 cache for the cores despite absent display output. Eight threads handle virtualized edge tenants.
DDR3 and DDR3L ECC over two channels to 32 GB feed the node. ECC is required for server use. Buyers pick the 1270L v4 where headless operation with high clocks must fit 45 W on a workstation board.
Socket and motherboard compatibility
The 1270L v4 fits LGA 1150 on C226 workstation boards with E3 v4 firmware. Consumer 8 and 9 series boards lack workstation validation and ECC wiring, so use C226 despite the shared socket. Check the board CPU list for the L suffix stepping.
ECC RDIMMs or UDIMMs populate two channels. The C226 chipset table on the socket page covers this codename. LGA 1151 boards never accept Broadwell parts.
Memory, PCIe and cooling
DDR3 and DDR3L-1333 to 1866 ECC over two channels to 32 GB suit micro servers. Registered configs depend on the board. Even populations protect bandwidth.
PCIe 3.0 with 16 lanes from the CPU serves a single discrete card or NVMe carrier. Headless nodes often add a basic card for setup. Chipset lanes handle SATA and USB.
Cooling uses the 75 mm LGA 1150 mount with 45 W tower or low profile sinks. No boxed cooler ships with tray workstation parts. Keep VRM airflow in mind on compact boards.
Upgrade paths
On the same socket the Intel Xeon E3-1283L v4 at 2.9 GHz to 3.8 GHz nearby trades base for turbo at similar power, while the Intel Xeon E3-1265L v4 at 2.3 GHz to 3.3 GHz with graphics covers lower power. All share LGA 1150 C226 boards where listed.
A move to E3 v5 needs a new C236 board. The 1270L v4 covers headless 45 W Broadwell workstations where clocks decide.
