Will a BOXDP965LTCK motherboard work with a Core 2 Quad 1066 FSB (Q6600)? It's listed as Core 2 compatible but they only say Duo and Extreme, not Quad - will it work anyways?
That board is an Intel desktop motherboard. Intel has a link to the supported CPU's.
See http://www.intel.com/support/motherboards/desktop/dp965lt/sb/CS-026556.htm?wapkw=dp965lt for which CPU's are supported.
If it is not in the list then it will not work.
If it is in the list and your BIOS version is too old then you want to update the BIOS before changing the CPU.
According to Intel, the P965 chipset will not support the Q6600 Intel P 965 Compatability
