Nice review. And I must say the Ridgeback heatspreaders look amazing.
But quick question. You seem very amazed at the fact that the kit can do 7-7-7-20 @ 1333MHz 1.5V. But I'm doing that right now with some very cheap 6GB Kingston value RAM, that was rated at 9-9-9-25 @ 1333MHz 1.5V and it's even 1T CMD rate. I don't even have heatspreaders on them. Am I really lucky here or is this something any kit can do @ 1333MHz? Of course I can't do more then 1600MHz 1.65V so that's where the Mushkin kit goes stratospheric.
