well i have done vmods in past. So i wouldnt mind doing it. But I am trying to sell my mobo. And i know in india not many people apperitiate moded motherboard

Anyway the vdim mod can be done without hardmoding the motherboard and its preety safe as you wont be damaging any components if you connect correct pins. The capacitor can easily handle 3.3V and if you have memory that is known to do good with more juice then 3.3v will definitely give some good results. Specially the patriot, BH-5/BH-6 and hynix d43.
If you have tccd chips 3.3 will end up killing that chip. so do little research before doing vmod.
Current transcend chips are useless for vdimm. They dont give any better results over 2.85v.
Hynix d43 is totally different story.
