TRFC 60 is overkill, it should not need to be that loose on most boards. 55 should be plenty.

As for voltages, you also should not need to pump vMCHthrough the roof, unless you're dead set on maintaining a tight tRD / PL while running a relatively high FSB. In addition, watch your vDIMM and keep them cool. No need to be pumping 2.2v+ into these chips; they don't need it and they don't want it.
