You can boost the core clock as well if you put the gpu in the p1 state.

p2 state: adjust memory
p1 state: adjust gpu boost clock

I think I will make code that does this automaticly with an option.. --Max-Boost --Max-memspeed

1. List all possible modes, parse the information and select the fastest for each gpu in the rig
2. Set p1 mode and set the max possible gpu-boost clock
3. set p2 mode and set the max possible memclock clock

The NVIDIA api is broken in x86 builds, so I will call the commandline from the c++ code in the same way I have done before. (windows only)

For 970 cards with 4pin+3pin connector, boosting is important to reach full speed. (but this costs more power)

Other cards will probobly trottle and perform worse..

(f.ex all the gtx 970 mini cards, and the 970 cards that are made small to fit in a small box.)
I can't get my 980ti to boost at all on mem.... Undecided

Sometimes I'm using nvidia inspector(from guru3d) to find out the actual state and boost the memory itself.
Maybe it can help You if You are using windows. It works on my 970 and 980.

How much hashrate are you getting with that? And for which algos?

Personally I never even OC memory clocks as it never giving me any noticeable speed just more power consumption and instability.
