What the Core i7-660UE is
The Intel Core i7-660UE is a dual core Arrandale embedded processor from August 2010. It runs two Westmere cores at 1.333 GHz base with Turbo Boost to 2.4 GHz, with Hyper-Threading for four threads. Each core carries 256 KB of L2 cache with 4 MB of shared L3 cache. Power is rated at 18 W.
The UE suffix marks ultra low voltage embedded with ECC memory and PCIe bifurcation support, unlike the mobile UM twin 660UM at the same clocks without ECC. HD Graphics run at 166 MHz with 500 MHz burst on this SKU. Against the 680UM it trails in turbo at the same 18 W.
Memory is DDR3-800 with ECC in two channels through the on package controller.
Socket and motherboard compatibility
The Core i7-660UE is soldered to the board in BGA 1288 and cannot be replaced. Embedded repair means board replacement.
Firmware must list the sSpec stepping. The CPU cooler compatibility by socket guide covers soldered rules, and the Intel Pentium U5600 page shows another BGA 1288 part.
Memory, PCIe and cooling
Memory is DDR3-800 with ECC in two channels up to 8 GB on embedded boards.
PCIe 2.0 supports bifurcation to 2x8 on embedded designs.
Cooling is a board specific assembly drawn for 18 W.
Upgrade paths
There is no CPU upgrade path on BGA 1288 because the chip is soldered. A 680UM adds turbo where ECC is not needed, otherwise a new board is required.
Frequently asked questions
What socket does the Core i7-660UE use?
BGA 1288, the soldered 1,288-ball package. The chip cannot be removed.
