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.
