Topic: Nvidia P106-090 6GB cards low hashrate (Read 210 times)

not sure if this is the same thing, 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.

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

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.

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

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.

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 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 links to the drivers seem to be dead so not sure if I need these drivers specifically
- I came across this post 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.
