Hello guys, as said in the title I'm thinking on volt modding my mobo, ASUS K8N. I don't care about Vcore or Vdimm adjustments as I'm well covered in that departement, but I would really like to Vmodd the chipset.
It is a NF3 250 chipset, and unfortunately in the BIOS there aren't any adjustments for Vchip.

Why do I want to Vmodd? I have the folowing problem: I manage to OC a lot, it goes up to ~266HTT at which point the CPU is quite well OCed and the ram is on divider and is a bit under DDR400. And what's the problem you ask me, it's a newcastle, what more do you want? Well, the thing is let's say I am @230HTT and I get fed up with gaming and I decide to shut it down. Haven't you guessed yet? Yes, I can't start it any more; I start the rig, doesn't boot so I make a forced ATX stop. After this the mobo resets the HTT to 200 and it boots up just fine, but while loosing the OC.

Quite anoying, and since I want to upgrade in 2-3 months I bought a multimeter and I want to start Vmodding. I'm no noob in electronics, I prefer treamers and solding as oposed to pencil modding, but I can't figure out how to increase the voltage for the chipset and I think this is the main cause for the cold-start issues I've been having.

Any help would be highly apreciated and rewarded. I'd rather buy you a beer when you reach Paris , but reps will have to do this time.
