Intel Core i3-4340TE socket: LGA 1150

What the Core i3-4340TE is

The Core i3-4340TE is an embedded Haswell dual core for long life low power hosts on LGA 1150. Intel set two cores and four threads at 2.6 GHz with 4 MB of Smart Cache. Power is 35 W on 22 nm from May 2014. Intel marks it as an embedded option for commercial temperature boards with extended supply.

At 2.6 GHz with four threads the chip handles control, signage and network tasks in sealed boxes. Cache size over 3 MB T parts helps steady working sets. Fixed clocks suit 24 hour operation with set fan tables. An SSD matters more than clocks for response in these roles. Builders pick TE where lifecycle beats peak speed.

HD Graphics 4600 from 350 MHz to 1.0 GHz drives industrial panels. DDR3-1333 and 1600 across two channels to 32 GB feed cores and graphics. ECC is supported where boards wire it. It is a Haswell socket for automation and medical hosts that need threads at 35 W for years.

Socket and motherboard compatibility

The 4340TE fits LGA 1150 on embedded Q87, H81 and C220 series boards with Haswell support. Makers publish TE support per board with long life firmware. Commercial desktop CPU lists may omit TE, so use the embedded board manual. Both 8 and 9 series desktop chipsets run Haswell, but embedded picks favor management and ECC paths.

Cooler mounting is 75 × 75 mm for low profile and conduction units. The CPU cooler compatibility by socket guide covers patterns. Chips for LGA 1151 never fit. The Socket vs chipset: what decides whether a CPU works guide explains tiers.

Lock the BOM with set memory and I/O, since industrial builds value repeat supply over speed steps.

Memory, PCIe and cooling

DDR3-1333 and 1600 in two channels to 32 GB is the memory target. ECC DIMMs work on boards that support the feature. Eight gigabytes suits control images. Two sticks aid graphics in HMI use. Board specs set voltage and timing for long runs.

Sixteen PCIe 3.0 lanes from the CPU serve motion, vision or network cards. Chipset lanes add SATA and USB for storage and sensors. Slot maps in the embedded manual decide multi card fit. Lane count rarely binds these thread light roles.

Cooling is a 35 W low profile or chassis conduction path. At 2.6 GHz heat is modest, but sealed enclosures need a clear path to the case. Follow maker torque and pad guidance for stable contact.

Upgrade paths

On the same socket the Intel Core i3-4330TE at 2.4 GHz is a slightly slower 35 W embedded twin with the same cache and graphics. The Intel Core i3-4350T at 3.1 GHz with 4 MB of cache is a higher clock 35 W option where embedded lifecycle is less strict. Both reuse DDR3.

A new platform needs a new board and memory. The 4340TE covers long life Haswell systems where 2.6 GHz threads at 35 W with ECC are the need.
