What the Xeon E3-1268L v5 is
The Xeon E3-1268L v5 is an efficient Skylake workstation part on LGA 1151 for compact servers. Intel set 4 cores and 8 threads at 2.4 GHz base with turbo to 3.4 GHz. Eight megabytes of Smart Cache cover tenants. Power is 35 W on 14 nm from October 2015. The embedded tag marks long availability.
The 35 W envelope with 8 threads suits edge servers with workstation features. Turbo covers bursts while efficiency holds sustained throughput. HD Graphics P530 from 350 MHz to 1000 MHz drives setup displays. ECC over two channels protects data.
DDR4 and DDR3L ECC to 64 GB feed the node. Buyers pick the 1268L v5 where 35 W with graphics and ECC must run edge workstation duty.
Socket and motherboard compatibility
The 1268L v5 fits LGA 1151 on C236 compact and embedded 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. Verify embedded lifecycle coverage for long deployments.
Memory, PCIe and cooling
DDR4-2133 and DDR3L ECC over two channels to 64 GB with up to 34.1 GB/s suit edge tenants. Paired modules feed P530. ECC is required.
PCIe 3.0 with 16 lanes from the CPU serves NICs and NVMe. Edge nodes use lanes for flash caches. P530 covers local management displays.
Cooling uses 35 W low profile sinks with chassis airflow. Efficiency tuning keeps fans slow. Cabinets still need air exchange.
Upgrade paths
On the same socket the Intel Xeon E3-1235L v5 at 25 W below trades threads for lower power, while the Intel Xeon E3-1270 v5 at 80 W above adds headless speed. All share C236 boards where listed.
A move to E3 v6 needs Kaby Lake-DT firmware. The 1268L v5 holds efficient graphics workstation duty in Skylake.
