It appears that you can only overvolt your card by 100mV with that version of MSI AB. What's the problem that seems normal to me?

MSI GTX460 Hawk is 'special' in the sense that AB does not give a target voltage figure but give a voltage adjustment. This adjustment ranges from -100mV to +100mV. The adjustment range is for AB versions 2.0.0 and 2.1.0.

But this +100mV limit is fixed by MSI and cannot be changed. It is simply the most voltage that you can add to your core. MSI puts this limit to the Hawks because they see the possibility of burning the card. BIOS editors will not be able to change this too. However, I think older versions and Beta version of 2.0.0 allows a wider range like -/+ 200mV. Try it if you have to but be extra careful.

Thanks for the help. Right now I'm OCing my 460HAWKs they are at 900mhz at +100 but only 62C so I feel like I can push them a bit further but I'm being limited by my voltage.

Keep in mind hat your card doesn't have any sort of VRM heatsinks so while your core temps may be fine and have room to go higher, your VRMs likely do not.

Hmm, how do I monitor my VRM temps alone?

I don't believe you can on your card, what you should be able to do though if you are dead set on increasing voltage further though is get some copper heatsinks for them. You will want to measure to see how many you will need for each card and verify that you have adequate vertical clearance. What you can do for vertical clearance is to splay the prongs of the heatsinks out a bit so that they take up less vertical space if need be. I think you should be able to go 2 cards with 3 sets of those, but like I said measure for yourself and see what you need. Enzotech makes copper heatsinks in all sorts of sizes.
