Just prior to starting on this review, I reviewed a Foxconn 925XE7AA-8KRS2 motherboard for Motherboards.org. Being a 925XE motherboard, this board supports both the 800 MHz FSB and 1066 MHz FSB CPUs. It also gives a good comparison point for the two CPUs in comparison to a 3.4 GHz Extreme Edition which I use in standard motherboard reviews.

Setup of both the 660 and 3.73 GHz Extreme Edition CPUs went without incident. Both CPUs were detected and configured correctly in terms of clockspeed and multiplier by the Foxconn board. CPU-Z found that the 3.73 GHz ran at 3.7333 GHz. The 3.6 GHz 660 ran at the expected 3.6 GHz. One oddity was found on the memory speed on CPU-Z. Memory on the 660 read as 266 MHz when it should have read 400 MHz, memory on the 3.73 read as 356.7 MHz instead of the 533 MHz it should have read as. Intel engineers said it was an issue with CPU-Z. Stability on the Foxconn board with the CPUs was excellent, with no crashes noticed.
