I have gone up to 2.0v on the ram and the qpi set to auto runs up to 1.5v's. mind you I don't think that this would be good long term though!
actually you got that wrong, the memory shouldn't excced the qpi voltage by 0.5V (thats why intel specs the max vdimm voltage with 1.85V, cause the max QPI voltage is 1.35V )
