-ttli   reduce entire mining intensity (for all coins) automatically if GPU temperature is above specified value. For example, "-ttli 80" reduces mining intensity if GPU temperature is above 80C.
   You can see if intensity was reduced in detailed statistics ("s" key).
   You can also specify values for every card, for example "-ttli 80,85,80". You also should specify non-zero value for "-tt" option to enable this option.
   It is a good idea to set "-ttli" value higher than "-tt" value by 3-5C.
   NOTE: Check "KNOWN ISSUES" section. GPU indexes in temperature control sometimes don't match GPU indexes in mining!

-mvddc   set target GPU memory voltage, multiplied by 1000. For example, "-mvddc 1050" means 1.05V. You can also specify values for every card, for example "-mvddc 900,950,1000,970". Supports latest AMD 4xx cards only in Windows.

I'm thinking about using the above features to manually specify my voltages/clocks/fan/temps etc in Claymore instead of using MSI AB (for a variety of reasons). Does anyone else do this, and if so, do you have any advice on does and don'ts, or other recommendations for transferring your MSI AB controls over to the miner (can you specify fan curve; is the default one pretty good)? My complaint with MSI AB is that the option to set all values for similar cards seems to cause a system hang every now and then, even though I know the settings work when applied individually, and manually adjusting voltages also periodically causes a hang, even though it's nothing related to the actual setting, just changing it. I'm using all brand new hardware, top of the line. Also, while tuning the rig for a new coin, I sometimes get stuck in a crash loop and have to disconnect a card so AB won't try to auto-set a value during boot. Then I turn off auto-set, but forget to turn it back on, etc. Too much effort when it seems like hardcoding them into the miner config might be easier (after it's all setup).

If anyone has example config for a 7x470 4gb sapphire nitro+ oc rig, that would rule. I'm already aware it largely depends on the ASIC quality of each card.

For fan control the options are "-tt" "-tstop" "-fanmin". There is no setting for fan curve, miner will adjust fan operation to achieve configured "-tt" temperature. Set it low and the fans will go louder, set it high and the fans will be much silent at low rpm. Tstop is safety measure I usually set to 85 or 90. I recommend you to leave a margin of 10 between tstop and tt. I specify fanmin for my RX cards in the range 25-30 %

The point in setting mvddc is to allow for lower cvddc. GPU voltage can't be set lower than memory controller's voltage or it just won't work. Your other option here is using "WattTool" from overclock.net and use GPU vddc offsets. That way you don't have to mess with mvddc. WattTool can also save profile settings for your cards for usage in you startup bat file.
