Can this CPU work on this Motherboard?

Is the "Intel Core 2 Quad Q6600 2.40 GHz, FSB 1066MHz, 2x4MB L2 Cache, Socket LGA775" compatible with the "Gigabyte GA-EP45-UD3L M/B, P45+ICH10, FSB 1600MHz, DDR2 1366+" ?

thanks

Supported as of BIOS F2; just because a CPU uses socket 775 does not automatically mean it will work on any 775 MOBO; new steppings of older chips, as well as newly released CPUs use different micro-code to support hardware-based features; BIOS, necessarily, operates at the micro-code level, and is likely to not work, or throw undefined (and, therefore, unhandled) exceptions, which is often worse than simply not working - can lead to corruption of other resources (like your HDD, or RAID array, if you're not lucky).

Best policy is to start here:

find the MOBO of interest, and look at its 'CPU Support List' to see if it will work, and, if so, what BIOS rev is required for that chip.
