What the Atom E665C is
The Intel Atom E665C is the fastest commercial Stellarton part on BGA 1466. It runs one Bonnell core with Hyper-Threading for two threads at 1.3 GHz with no turbo, backed by 512 KB of L2 cache. Power is rated at 3.6 W on a 45 nm process. Intel lists November 22, 2010 as the launch date with commercial temperature range of 0 to 70 C.
At 1.3 GHz it leads commercial Stellarton boards in control tasks at the same 3.6 W as the 1 GHz E645C. The E665C is the commercial version, while the E665CT is the industrial version at identical clocks and power. GMA600 graphics at 400 MHz cover kiosk displays.
Memory is single-channel DDR2 up to DDR2-800 with up to 2 GB fixed per board.
Socket and motherboard compatibility
The Atom E665C is soldered to the board in BGA 1466 and cannot be replaced. Board replacement is the only upgrade path.
Compatibility depends on firmware with the Stellarton B0 stepping. The CPU cooler compatibility by socket guide covers soldered rules.
Memory, PCIe and cooling
Memory is single-channel DDR2 up to DDR2-800 with up to 2 GB, fixed per board. ECC is not part of this SKU.
Expansion comes from 4 lanes of PCIe 1.0a plus USB and display outputs.
Cooling has no retail answer. The 3.6 W envelope suits passive spreaders.
Upgrade paths
There is no CPU upgrade path on BGA 1466 because the chip is soldered. Keep the E665C where the fastest commercial Stellarton core covers the workload.
