pill gives only 2-3% icnrease, my GTX1080Ti zotac amp uses only 1500 core with TDP70% and 80+ core oc, it's rock stable, my rig needs around 26gb virtual memory and it hasn't crashed yet in 4 day mining, just do one system restart per day, well in readme file it says that you can put intensity 0 to 6 and default intensity is 6, after mining dev fee session your hasrate will drop, but in reality it' same as before dev fee session, my hashrate is around 13.63-13.65mh/sec, after dev fee it never goes 13.5mh/sec, but mintpool always shows 13.7 or even higher, it makes around 0.88 zcoins per day, i already made 0.00313411 BTC + 0.35 zcoin, that around 3 day and 15 hours of mining
It occured to me... I think you mean to say you're getting 13.5 KH/W - not KH/s - KH/W refers to power consumption vs your hashing - your actual speed is shown on KH/s.
In any event, can you copy and paste the GPU info from CD? It should look like this:

here's my result
https://i.imgur.com/ig2stBm.png (my rig operates around 14.7mh.sec without using teamviewer) i haven't tried maximum core oc (without any memory oc) maybe it's has even higher hashrates without altering miner stability, now i'm mining gricoin on f2pool, maybe later i switch to mtp algo again on mintpool, it has lower fee (3% VS 0.9%) as well as european server VS chinese with lower ping, lower payment threshold (3 grins vs 1 zcoin), mtp algo needs around 2-3gb less virtual memory per one 8-11gb nvidia GPU than c29 algo and at the moment according to whattomine miner calculator zcoin pays more in bitcoins than grincoin with c29 algo (using bminer), electricity costs and gpu temps (well mining gpu with mtp algo maybe 2-3 degrees celcius warmer than grin using more or less same oc and TDP settings) should be more or less same using TDP 70% and some memory and core oc, i used default intensity -6, stability was perfect without any miner resets and driver crashes, i haven't seen any hashrate increases either for mtp nor c29 algos later, maybe it's highest that miner devs can achieve at the moment without breaking stability, or they need more time to make more optimizations, also zcoin price is more stable than grincoin and there's less price fluctuations at the moment
well i did some more oc on core i got following results:
https://i.imgur.com/FA4L0kQ.pngmaybe i could achieve even higher results with more oc on core (memory oc +500 gives very low hashrate increase as well as using pill, maximum around 0.5mh/sec in total) i think around 13.85mh/sec is achievable
lol with intensity -8 i got 14mh/sec, pretty good results:
https://i.imgur.com/8epHBCx.pngmaybe it's better to use higher intensity (8 instead of default 6) + only core oc (memory oc 0 + pill) with intensity 8 i think 14.10-14.15mh/sec is easily achievable with maximum stable core oc and TDP 70% in that case average daily income would increase from 0.00115-0.0012 bitcoin to 0.0012-0.00125 and temp increase should be only 1-2 degrees Celcius
so it seems that maximum intensity for CD miner is 8 and not 6 (at least for mtp algo), when i set intensity -9 it run only on 8, as for miner droping hashrate after dev fee i think that it calculates average hashrate with dev fee time as well, so average hasrate is lower after dev fee ends, but in reality it's same than before dev fee started, more important is pool average daily hashrate
it would be nice if CD had C29-31 algo support as well for mining grincoin
