Incorrect intensities with CcminerAlexis78 on GTX1080ti

[UselessGuru]

I am referring to https://github.com/MultiPoolMiner/MultiPoolMiner/issues/1702 & https://github.com/nemosminer/ccminerAlexis78/releases

I get the following error when running your miner on a GTX 1080ti:

ccminer.exe -a x17 -o stratum+tcp://europe.mine.zergpool.com:3737 -u 1GPSq8txFnyrYdXL8t6S94mYdF8cGqVQJF -p BlackBox,c=BTC

It appears that the miner is using incorrect default intensity (22.5). If I change it to '-i 21.5' the miner runs very well.

Other algos report the same problem: The same goes for C11. Default intensity 22 is too high -> lower intensity to 21.5. The same goes for X11evo. Default intensity 22 is too high -> lower intensity to 21.

yip i know that... check my ccminerAlexis78.ps1 in "miners" folder has correct intensity already

I cannot test, but do these intensities also work for other cards, e.g. GTX1060 or GTX1070? Since you have the source code (and know how to compile) it should be easy to 'fix' it.

[nemosminer]

yes works on all cards from 10603gb to 1080ti and everything in between...

what should be easy to fix? use correct intensity and you wont have a problem...
