AFAIK the non-reference cards use cheaper VRMs which makes voltage control impossible

No you can not because the reference models use the volterra VR's which are software programmable. The non reference models use different variants of VR's which are only regulated through the BIOS which sometimes does not work or is limited. The BIOS mod sometimes does not work even though you have sucessfully modded the BIOS to increase the voltage. The only way to confirm if the BIOS mod actually works is by measuring it with a DMM

Your only chance of obtaining higher core voltage is through modding your original BIOS with RBE or by doing a hardmod.

Do not flash it with anything other than the factory BIOS(you can mod this of course). Any other BIOS will most likely brick your card.

YMMV. Not every non-reference card is the same (Get it..?)
