I just grabbed a few of these cards thinking I was getting a good deal on them, the seller did mention 22Mhs on Ethash in his listing, I did a quick research about the cards and I came across  this video of Bits be Trippin (https://www.youtube.com/watch?v=TzuSwO6I_oA) it clearly showed 22Mhs with great efficiency (the cards have a 75W TDP) and they run very cool.

After 2 days of playing around:

- I can't get the cards to hash at more than 14Mhs on Ethereum/Ethereum classic, I can, however, get 21MHs on expanse (lower epoch, smaller dag)
- I tried Linux and windows, with the same results, I tried drivers from 384 to 440
- On the site of Manli (http://www.manli.com/en/support) links to the drivers  (http://download.manli.com:8080/drivers/Coin%20Mining/385.41_win10_64bit_international.zip) seem to be dead so not sure if I need these drivers specifically
- I came across this post (https://forum.hiveos.farm/t/nvidia-p106-090-slow-hash-rate-after-oc-only-15mh-s-help/11034/10) mentioning the dag size issue so this is where it clicked for me
- These cards are 6GB cards, so they definitely still have enough room for the dag file at least for a couple more years.

My issue is that these cards are pretty much useless at everything except ethash, they have half of the computing units that of a normal GTX1060 6GB or a P106-100 cards (5 instead of 10), it seems like they were designed specifically for Ethash mining, I am hoping one of you out there have answers to how to resolve this.

Edit: At this point I know it is the DAG file size, I am trying to understand why is this happening when the card still has plenty of memory left? my hope is that someone has already figured out a solution since I can't find many people complaining about this card.

It's some how the DAG, i have a couple of these I got for 25 dollars each and they work almost on the same level as 1050TI as of right now at around 14mhs with ETH/ETC. if you try another ethash algo with a lower dag you do get 22mhs.

This post may offer more clues to the decreasing hashrate...

Oh damn! what a waste of money, I always do my research, but this one was really tricky! is there any workaround to this issue? what causes the hashrate drop? I want to understand the technical cause behind this since it really doesn't make sense to me.

I said the same thing to you in r/GPU mining... didn't want to listen.

not sure if this is the same thing (https://www.reddit.com/r/gpumining/comments/fefgr9/nvidia_p106090_6gb_cards_low_hashrate/fjo4kr5/), but nonetheless, I find it strange that not many people are complaining about these cards, a quick google search doesn't return much, this is why I am hoping that there is a solution to this issue out there.
