If you want to try, I got mine stable at 211bclock @1.5VQPI and 213bclock @1.55VQPI.
Thank you for this information! What I fear may be true: I have a weak or at least mediocre IMC.

I think I read earlier in the thread that G.Skill support replied to an e-mail regarding QPI/VTT voltage that it is ok to go high with it as long as there is sufficient cooling. I'm hoping the Intel max VTT spec of 1.35v is only specified because of the issue with DDR3 kits requiring too much voltage and causing the voltage differential issue with the QPI. That and maybe also the increased heat.
