What the Xeon E5-2448L is
Intel Xeon E5-2448L is an eight core Sandy Bridge-EN server processor that Intel released in May 2012 for efficient dense systems. It runs at 1.8 GHz base with turbo to 2.1 GHz, with 20 MB cache and Hyper-Threading for 16 threads. Power is rated at 70 W on a 32 nm process. ARK lists the vertical segment as Embedded for appliance and carrier designs as well as classic servers.
No integrated graphics are present. Memory reaches DDR3-1600 over three channels with ECC, which separates it from six core parts capped at 1333. The chip gives 24 PCIe 3.0 lanes plus one 8.0 GT/s QPI link for dual socket pairs.
Eight slow cores with a large cache suit parallel appliances that scale with threads rather than clocks. Boards use registered DIMMs and fixed firmware for long service. The LGA, PGA and BGA: CPU package types explained guide contrasts this socketed server part with soldered BGA designs.
Socket and motherboard compatibility
The Xeon E5-2448L fits LGA 1356 in FCLGA1356 form. The controller is the C600 series on Socket B2, with C602 on Romley-EN boards. The vendor list must show the exact E5-2448L string with Sandy Bridge-EN microcode.
At 70 W dense chassis with vendor heatsinks handle it. The Socket vs chipset: what decides whether a CPU works guide covers server pairing.
Memory, PCIe and cooling
Memory support is DDR3 at 800, 1066, 1333 or 1600 MT/s, three channels, with ECC and registered DIMMs. The 1600 step helps sixteen threads share bandwidth. Populate all three channels per socket.
PCI Express is 24 lanes of PCIe 3.0 per socket for network and storage I/O. The QPI link at 8.0 GT/s joins two sockets. Keep cache heavy I/O near its socket on NUMA boards.
Cooling is vendor qualified for 70 W with chassis airflow. No retail mount exists. Watch inlet temperatures in dense enclosures.
Upgrade paths
On LGA 1356 the Xeon E5-2448L can move to faster Sandy Bridge-EN or Ivy Bridge-EN eight core parts on the same board, where power and vendor lists allow. Memory and storage carry over. A higher clock comparison is Intel Xeon E5-2450L at the same 70 W.
A platform move means a DDR4 generation. Keep the node for threaded appliance duty where sixteen Sandy threads still work.
Frequently asked questions
What socket does the Intel Xeon E5-2448L use?
It uses LGA 1356. C600 series Socket B2 boards carry it.
Is the Xeon E5-2448L a Server or Embedded part?
ARK lists the vertical segment as Embedded, for appliances as well as servers.
What memory does the Xeon E5-2448L use?
DDR3 at 800, 1066, 1333 or 1600 MT/s, three channels, with ECC and registered DIMMs.
Is the Xeon E5-2448L for dual socket boards?
Yes. The 2400 numbering allows two sockets with one QPI link.
