Unboxing and Photography
The Intel Core Ultra 9 285K comes in a special retail packaging. The processor is enclosed in a jewel-case that peeks out of the side. The front face of the box has some reflective bits that set it apart from retail boxes of other processor models in the series.
This looks like an LGA1700 CPU, but trust us, it won't fit on your older motherboard. The dimensions are identical to ensure cooler compatibility, but the key notch is different. Intel created space for those 151 extra pins by reducing the "island" in the middle of the land-grid.
Installing an LGA1851 processor is identical to that of an LGA1700 processor.
