My bone-stock Asus Dual OC hashes at 24Mh/s out of the box.
I've seen guys push Gaming X cards up to 31 especially when memory type is Samsung.

Copy straps 1750>2000 or boost your memory clock up to 2100 or 2150.

@topic:

Tried v10 this morning, just copying and pasting my config.txt and dpools.txt onto the new version.

Verdict:
My overclock/underclock and undervolt are set in bios so I can say that it still bypasses set voltage. You have to do -cvddc and -mvddc on the cofig for it to work BUT voltage offsets are very unstable - jumps from 1.025 to .900mV in 2-3 seconds. About 15-20w higher power draw too as per GPU-Z and around 200w more at the wall.

Since I can control my undervolts in Trixx better, i'll just be using v9.8 for now.
