What the Xeon E7-8867L is
Intel Xeon E7-8867L is a ten core Westmere-EX server processor that Intel released in April 2011 for large low power boards. It runs at 2.13 GHz base with turbo to 2.53 GHz and includes Hyper-Threading, so 10 cores give 20 threads. Cache is 30 MB Intel Smart Cache. Power is 105 W on a 32 nm process.
The L suffix marks low power for dense racks where watts per socket decide node counts. Clocks sit below the 130 W flagships while cache matches at 30 MB. Fixed firmware keeps behavior predictable.
There is no integrated graphics on this die. Each socket carries four DDR3 channels with ECC. The chip launched in the second quarter of 2011.
Socket and motherboard compatibility
The Xeon E7-8867L fits LGA 1567 in FCLGA1567 form. Large server boards with the Intel 7500 chipset carry it. The board BIOS must list the exact E7-8867L string.
CPUs connect over QuickPath Interconnect, while PCIe comes from the chipset. A board that lists E7-8800 strings is the safe choice.
Memory, PCIe and cooling
Memory support is DDR3, ECC registered with buffering, four channels per socket. Fill risers in matched sets per the board manual. Capacity follows the board design.
QPI links connect sockets on multiprocessor boards. PCIe comes from the Intel 7500 chipset rather than the processor.
Cooling uses board specific server heatsinks under data center airflow. Lower TDP eases chassis thermal budgets.
Upgrade paths
On LGA 1567 the E7-8867L can move to the E7-8860 for higher clocks at 130 W on a similar board. Memory and storage carry over where the board lists both strings. A same family low power reference is the E7-4807 class at 95 W.
A platform move to a current server socket needs new boards and DDR4 memory. Keep the E7 board for efficient scale duty.
Frequently asked questions
What socket does the Intel Xeon E7-8867L use?
It uses LGA 1567 on large server boards.
What does the L suffix mean on the Xeon E7-8867L?
The L suffix marks low power at 105 W with the same 30 MB cache.
