I'm also not perfectly comfortable with 1.65V, but considering these are PSC chips after all (most of them run like that), and the RAM doesn't stop scaling earlier like some other people experienced, my guess is that it's reasonably safe.

And I don't believe there is much difference between a plain heatsink and one with twists and bends as long as you get just enough airflow to cool it down a little (my kit gets only mildly hot while Priming at 2133 1.65V).
Hmm, your response has made me think about trying 1.65v then )))) Plus I guess having 3 viper fans right above the memory on my TFC 360 would keep it cool.

I am surprised you need to have tWCL at 8 though with CL at 7, they should always be the same or at least the memory should always be able to handle them both being the same, although I suppose there is always slight variations in kits, have you tried posting on the gskill.us forums, I would think they might replace them for you given that as it should be able to run at those parameters, I actually have 3 of these kits and all of them run with tWCL and CL being the same.
