What the Xeon E5-2650L is
Intel Xeon E5-2650L is an eight core Sandy Bridge-EP server processor that Intel released in March 2012 for efficient dual socket servers. It runs at 1.8 GHz base with turbo to 2.3 GHz, with 20 MB cache and Hyper-Threading for 16 threads. Power is rated at 70 W on a 32 nm process. The wider turbo over the 2648L adds responsiveness at the same power.
No integrated graphics are present. Memory spans DDR3-800 to 1600 over four channels with ECC, and the chip provides 40 PCIe 3.0 lanes plus two 8.0 GT/s QPI links. Sixteen threads suit virtualization hosts that pack many guests per watt.
Boards pair it with registered DIMMs in 1U twins. Bursts reach 2.3 GHz for foreground tasks while all core loads stay efficient. The How to find your CPU socket type guide shows how to confirm the socket before ordering.
Socket and motherboard compatibility
The Xeon E5-2650L fits LGA 2011 in FCLGA2011 form. Dual socket Romley boards with the C600 series controller carry it. The vendor list must include the exact E5-2650L string.
At 70 W dense cooling with vendor heatsinks applies. The Socket vs chipset: what decides whether a CPU works guide covers server rules.
Memory, PCIe and cooling
Memory support is DDR3 at 800, 1066, 1333 or 1600 MT/s, four channels, with ECC and registered DIMMs. Full population matters with sixteen threads.
PCI Express is 40 lanes of PCIe 3.0 per socket. Two QPI links at 8.0 GT/s join pairs. NUMA placement guides I/O assignment.
Cooling is vendor qualified for 70 W. No retail mount exists.
Upgrade paths
Within LGA 2011 the Xeon E5-2650L can step to faster Sandy Bridge-EP or Ivy Bridge-EP eight core parts on the same board, where power allows. Memory and storage carry over. A v2 comparison is Intel Xeon E5-2650L v2 on the same socket.
A platform move means a DDR4 generation. Keep the node for dense guest duty.
Frequently asked questions
What socket does the Intel Xeon E5-2650L use?
It uses LGA 2011. C600 series dual socket boards carry it.
How is the Xeon E5-2650L different from the E5-2648L?
Turbo is 2.3 GHz instead of 2.1 GHz at the same 70 W and 20 MB cache.
What memory does the Xeon E5-2650L use?
DDR3 at 800, 1066, 1333 or 1600 MT/s, four channels, with ECC and registered DIMMs.
Is the Xeon E5-2650L for dual socket boards?
Yes. The 2600 numbering allows two sockets.
