so i just brought an asrock p67 extreme 6 and corsair 4gb of ram, only to discover that particular model of ram isnt supported by the moo.
its still dual channel and has a voltage of 1.5V
my question is will it still work or do i need to cancel the order on the ram and replace it. (yes im aware of the sandybridge chipset problems)
You mean that the specific RAM model isn't on the 'tested and approved' list put out by the manufacturer? There's no way that the board manufacturers can keep up with all of the RAM types, and they wouldn't test them all even if they could.
If the RAM is 1.5v spec and from a good manufacturer, it will probably work.
