What the Xeon E5-2440 is

Intel Xeon E5-2440 is a six core Sandy Bridge-EN server processor that Intel released in May 2012 for performance dual socket servers. It runs at 2.4 GHz base with turbo to 2.9 GHz, with 15 MB cache and Hyper-Threading for 12 threads. Power is rated at 95 W on a 32 nm process. High base clocks for the EN line suit application servers that run hot during business hours.

No integrated graphics are present. Memory is DDR3 at 800, 1066 or 1333 MT/s over three channels with ECC, and the chip gives 24 PCIe 3.0 lanes plus one 7.2 GT/s QPI link. Twelve fast threads handle databases and application tiers with consistent latency.

Boards pair it with registered DIMMs and fast RAID in 1U and 2U chassis. All core work sits near 2.4 GHz, which keeps response direct under load. The How to find your CPU socket type guide shows how to confirm the socket before ordering.

Socket and motherboard compatibility

The Xeon E5-2440 fits LGA 1356 in FCLGA1356 form. C600 series Socket B2 boards on the Romley-EN platform carry it, with C602 the reference. The vendor list must carry the exact E5-2440 string with Sandy Bridge-EN microcode.

At 95 W full size server heatsinks apply. 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 or 1333 MT/s, three channels, with ECC and registered DIMMs. Three populated channels per socket feed twelve threads without bottlenecks.

PCI Express is 24 lanes of PCIe 3.0 per socket for network and storage controllers. The 7.2 GT/s QPI link joins socket pairs. NUMA placement guides I/O assignment.

Cooling is vendor qualified for 95 W with directed chassis airflow. No retail mount exists.

Upgrade paths

Within LGA 1356 the Xeon E5-2440 can step to eight core Sandy Bridge-EN or Ivy Bridge-EN parts on the same board, where power allows. Memory and storage carry over. A close six core step below is Intel Xeon E5-2430.

A platform move means a DDR4 generation. Keep the node for application tier duty where fast Sandy cores still deliver.

Frequently asked questions

What socket does the Intel Xeon E5-2440 use?

It uses LGA 1356. C600 series Socket B2 boards carry it.

How is the Xeon E5-2440 different from the E5-2430?

Base is 2.4 GHz instead of 2.2 GHz, and turbo is 2.9 GHz instead of 2.7 GHz, at the same 95 W.

What memory does the Xeon E5-2440 use?

DDR3 at 800, 1066 or 1333 MT/s, three channels, with ECC and registered DIMMs.

Is the Xeon E5-2440 for dual socket boards?

Yes. The 2400 numbering allows two sockets.
