I've tried 1x2GB, 2x2GB, 4x2GB in my rig and all overclock the CPU to the same... can't get above 2.42ghz without it throwing a wobbly so in my case, the amount of ram makes no difference whatsoever... that's volted at 2.1v and 2.2v on the ram...

Entirely dependent on the mobo.
I know for a fact my P965-DS3 needed more NB volts to stabilise 4GB.
