Intel Core i7-3517UE socket: BGA 1023

What the Core i7-3517UE is

Intel Core i7-3517UE is a dual core Ivy Bridge embedded processor that Intel released in June 2012 for carriers and boxes with long lifecycles. It runs at 1.7 GHz base with turbo to 2.8 GHz, with 4 MB Intel Smart Cache and Hyper-Threading for 4 threads. Power is rated at 17 W on a 22 nm process. The UE suffix marks embedded use with ECC memory on qualified boards.

Graphics are Intel HD Graphics 4000 at 350 MHz to 1000 MHz. The block covers control displays and video without a card, while ECC catches single bit errors in long running tasks where the carrier enables it. The memory controller takes DDR3 and DDR3L at 1333 or 1600 MT/s for up to 16 GB.

The 17 W envelope allows passive or small active cooling in sealed boxes. Fixed carrier firmware locks the lifecycle, so behavior stays predictable across years. The How to find your CPU socket type guide shows how to confirm the soldered package before ordering a carrier.

Socket and motherboard compatibility

The Core i7-3517UE solders to BGA 1023 with 1,023 balls in a 31 by 24 mm footprint and cannot be moved. Embedded carriers qualify each model with a fixed board and BIOS for a locked lifecycle, so another UE part is not a drop in swap even within the same package.

Power and firmware decide service. The 17 W heatsink is sized by the carrier, and the BIOS must list the exact Core i7-3517UE string with ECC wiring where used. The CPU cooler compatibility by socket guide notes soldered parts have no desktop mount pattern.

Memory, PCIe and cooling

Memory support is DDR3 and DDR3L at 1333 or 1600 MT/s, two channels, up to 16 GB, with ECC where the board wires it. ECC matters for signage, control and kiosk loads that run for months without reboot. Capacity follows the carrier design, not the CPU maximum alone.

PCI Express is 16 lanes from the CPU at PCIe 3.0, split by the carrier for storage, wireless and I/O. Most embedded boards keep graphics internal and devote lanes to SATA and expansion. There is no retail graphics slot to consider.

Cooling uses the carrier heatsink for 17 W. Sealed boxes rely on conduction and directed airflow, so ambient limits matter more than fan curves. Service is limited to cleaning and storage swaps where the design allows access.

Upgrade paths

There is no CPU upgrade path on soldered BGA 1023. The Core i7-3517UE cannot be removed, so a faster carrier means a new board or a new box. Within the embedded family Intel Celeron 1047UE shows a slower UE option on the same package, but carriers rarely mix models.

A platform move means a new embedded box on a current BGA package with DDR4 memory and current OS support. Recycle the old unit through a proper e waste path once data is wiped.
