Hi I was wondering if you guys are doing only simple overclocking with afterburner or forced p-states.
On my EVGA 660Ti I use nvidia inspector to force p2-state which gets me up to 1215MHz (300MHz over stock).
Also my hashrate got a bit more stable with this and autotuning gets much more precise results since then.

This gets me 340khash/s for scrypt and 3.5khash/s for scrypt-jane.
This is with the 2014-1-22 version.
So I´m wondering why I´m actually still below a value from the scrypt-jane spreadsheet which apparently uses almost no OC.
I´ve tested lots of kernel cfgs but I can´t seem to get any higher.

Any ideas?

My exact config:
scrypt: --interactive=0 --hash-parallel=2 --launch-config=Y112x2 --texture-cache=1 --single-memory=0
scrypt-jane: --interactive=0 --hash-parallel=1 --launch-config=K7x23 --texture-cache=0 --single-memory=0 --lookup-gap=3

OC:
P0: clock-offset +160; mem-offset +300; power-target 153% (actually uses about 142% TDP)
P2: clock 1215MHz; forced
Driver: 332.21

Your, Mem offset might be going the wrong direction. There is zero bottleneck for Scrypt-Jane (@ -L 1) and almost none for Scrypt or Scrypt-Jane (@ -L 2+) in terms of memory throughput most times.

This may just be a Titan specific observation, but I literally see zero change to hash rate swinging from -502 to +300 in 100 steps, none. All a positive memclock did was raise the TDP utilization of the card for zero gain. You might find that lowering the Memclock will allow a more stable feed to the GPU and allow a higher clock as a result. If not at least you will see a reduction in TDP % saving you power costs in the long run.
