The next thing I would suggest trying is setting the TDP Base Entry, 3D Base Entry, and Boost Entry to: Entry 0 (disable boost), and up the base to 1455 or something. I have mine set to 1531, but if you're having problems getting that high, I'd probably go more conservative.
Then, in PCX, try enabling KBoost. That'll lock in the boost clock and the boost voltage for your card. I've found that it helps me keep the higher clocks a little more stable. Like disabling C-States when overclocking a processor to it's limits.
If you're on air, you may also want to consider upping the temp target to 86. Your settings is pretty low there, and if it reaches that temp, it'll throttle. That could be a contributing factor in what's holding you back.
