What the Xeon E5-2450L is
Intel Xeon E5-2450L is an eight core Sandy Bridge-EN server processor that Intel released in May 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 2448L adds 200 MHz for bursts at the same power.
No integrated graphics are present. Memory spans DDR3-800 to 1600 over three channels with ECC, and the chip provides 24 PCIe 3.0 lanes plus one 8.0 GT/s QPI link. Sixteen threads with a large cache suit virtualization hosts that pack many small guests.
Boards pair it with registered DIMMs in dense 1U and 2U chassis. All core loads sit near base clock, while lightly threaded tasks reach 2.3 GHz. The How to find your CPU socket type guide shows how to confirm the socket before ordering.
Socket and motherboard compatibility
The Xeon E5-2450L fits LGA 1356 in FCLGA1356 form. C600 series Socket B2 boards, principally C602 designs on the Romley-EN platform, carry it. The vendor CPU list must include the exact E5-2450L string.
At 70 W standard 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, three channels, with ECC and registered DIMMs. Full channel population matters most with sixteen threads sharing bandwidth.
PCI Express is 24 lanes of PCIe 3.0 per socket for Ethernet and RAID controllers. The 8.0 GT/s QPI link joins socket pairs. NUMA placement guides I/O assignment on dual boards.
Cooling follows the vendor list for 70 W with directed airflow. No retail cooler fits the narrow server ILM.
Upgrade paths
Within LGA 1356 the Xeon E5-2450L can step to faster Sandy Bridge-EN or Ivy Bridge-EN eight core parts on the same board, where power allows. Memory and storage carry over. A lower turbo comparison is Intel Xeon E5-2448L at the same power.
A platform move means a DDR4 server generation. Keep the node for dense guest duty where sixteen threads still pack well.
Frequently asked questions
What socket does the Intel Xeon E5-2450L use?
It uses LGA 1356. C600 series Socket B2 boards carry it.
How is the Xeon E5-2450L different from the E5-2448L?
Turbo is 2.3 GHz instead of 2.1 GHz at the same 70 W and 20 MB cache.
What memory does the Xeon E5-2450L use?
DDR3 at 800, 1066, 1333 or 1600 MT/s, three channels, with ECC and registered DIMMs.
Is the Xeon E5-2450L for dual socket boards?
Yes. The 2400 numbering allows two sockets.
