Core voltages are set as (1mV per 1MHz)+10mV, and my memory voltage is brought down to 1500mV.

I use a ratio of Clock Speed x 1.535 = Memory Speed. Intensity = 20, concurrency = 22,400, 1 GPU thread.

955/1466 -> 565 - 580kh/s
977/1500 -> 585 - 595kh/s
1010/1550 -> 590 - 615kh/s
1043/1600 -> 605 - 635kh/s
1075/1650 -> 640 - 658kh/s
1113/1700 -> 670 - 680kh/s
1140/1750 -> 675 - 695kh/s

The slower of the two is the launch day model, and is probably slower because it's displaying my desktop at a 144hz refresh rate. I can only run the cards at 700+kh/s during the winter when my ambient temps are 60F or lower.

I just found out that apparently I can't change the voltage on my card (Trixx shows the changes, but GPU-Z and CGMiner both show the stock voltage). Along with this, I can't change the memory clock speed (Trixx again shows what I set it to, but CGMiner and GPU-Z show different).

That sucks, Sad
