What is the difference among 3 intensity setting flag?
-li
-ethi
-dcri

I can see
-dcri adjust intensity w/o change hashrate
-ethi adjust hashrate
-li seems similar to ethi, is there any differnce?
-ttli apply li when temperature threshold is reached.

Actually, all these settings will increase or decrease the mining intensity, but in different ways depending on how you want to use them.

-dcri Used for individual tuning of each GPU for maximum hash rate.
   It will definitely increase or decrease your hash rate depending on how well it is tuned.
   If it is tuned badly then the intensity is actually lower and you will get less hash rate
   but lower temp on that GPU. Tuned well and the hash rate goes up and also the temp. You want this
   tuned to the highest hash rate on each card.

-ethi Used to set the Max intensity per card. If you set this to the max allowed your cards
   will mine to the maximum intensity allowed by the miner. However, if you have badly
   tuned the -dcri then that card will still not be getting you the maximum intensity.
   Also, the -li if used will lower the intensity if you have it set. And of course the -ttli will
   also cause the card to use a lower intensity if the temp you have specified is reached.

-li Used if youre having a heat problem with a card. It basically decreases the
   intensity of the GPU therefore lowering the heat.

-ttli Automatically decreases the intensity for a card if the temp you specify is exceeded, that lowers the temp of that card.

Here is the way I think these setting should be used. It is how I do them and I have no issues.
If anyone else has a better or different method I would like to know what it is please.

1st:
-ethi
Set this to maximum value to get the most mining intensity and the highest hash rates.

2nd:
-dcri
Tune your cards to get the maximum hash rate on each card. Each card will probably have a different setting.

3rd:
-ttli
I set this to a temp that I don't want my cards to go above at any time.
I set mine to 75. I don't want any of my cards to go above 75. If for some reason they do
then the miner will automatically reduce the intensity on that card and lower the temp for me.
If this happens you can see it in the logs. Then you can set the -li for that card only to lower
it's intensity so that it doesn't happen again.

4th:
-li
I would only use this to reduce the intensity on a card that was giving me a temp issue
that the other settings did not handle.

If all your cards have slightly high temps after doing this, then the best thing to do is
use the -ethi and lower that number for all the cards. All cards will then mine at a lower intensity
and the temp will be dropped on them all.

These are my opinions and experience of how these setting work.

Edit: Note

All this assumes that you have not overclocked to a point where increasing the intensity will cause you a stability issue.

thanks,

-ethi: default = max hashrate
-dcri: default = auto tune for AMD, not changeble for nVidia (constant @ 30)
-ttli: I didn't set, I use tstop/tstart instead since it works for both AMD and nVidia. Does -ttli work for nVidia as well? If so, I could use -ttli as bridge
-tt 60 -ttli 73 -tstop 77 -tstart 59
afterburn also sets temperature threshold per GPU, once it reaches the threshold, I think it throttles the GPU
-li: never used before, hopefully will never use it
