What the Xeon E3-1260L v5 is
The Xeon E3-1260L v5 is an efficient Skylake workstation part on LGA 1151 for compact servers. Intel set 4 cores and 8 threads at 2.9 GHz base with turbo to 3.9 GHz. Eight megabytes of Smart Cache cover tenants. Power is 45 W on 14 nm from October 2015. No integrated graphics exist.
High turbo at 45 W suits bursty edge servers with BMC graphics. Base clocks hold steady throughput while single thread spikes reach 3.9 GHz. Eight threads handle virtualized services. The 45 W envelope fits short depth chassis with modest cooling.
DDR4 and DDR3L ECC over two channels to 64 GB feed the node. ECC guards edge data. Buyers pick the 1260L v5 where 8 threads with high turbo must fit 45 W on C236.
Socket and motherboard compatibility
The 1260L v5 fits LGA 1151 on C236 compact workstation boards. The socket C236 table covers Skylake-DT. Low power firmware keeps thermals in check. Consumer boards lack E3 support.
ECC UDIMMs to 64 GB are standard. LGA 1150 never accepts Skylake. BMC graphics cover setup without an iGPU.
Memory, PCIe and cooling
DDR4-1866 and 2133 ECC over two channels to 64 GB suit compact tenants. DDR3L ECC suits reuse. Bandwidth covers 8 threads well.
PCIe 3.0 with 16 lanes from the CPU serves NICs and NVMe. Edge nodes use lanes for flash caches. A fast NIC suits cluster links.
Cooling uses 45 W low profile sinks with chassis airflow. Bursty turbo needs ventilation. No boxed cooler ships.
Upgrade paths
On the same socket the Intel Xeon E3-1240L v5 at 2.1 GHz to 3.2 GHz with 25 W tuning below saves power, while the Intel Xeon E3-1268L v5 at 2.4 GHz to 3.4 GHz with P530 graphics adds displays. All share C236 boards where listed.
A move to E3 v6 needs new firmware. The 1260L v5 holds efficient high turbo duty in Skylake workstations.
