Anybody using 1070? Two years ago all of the 1070s were pushing a constant 30-32 mh/s. Now, only one (EVGA) of them is pushing 29 mh/s, the rest (AERO MSI) are in the low 22-23 mh/s. I understand the 1070s are affected by the increased DAG size as well as nvidia's drivers. However, how come one of my card still pushes similar numbers to two years ago, is the EVGA using a more efficient memory or what causes this? I've tweaked mem/clock and TDP but nothing. Thanks.

OS: Win 10
Newest Nividia drivers
Latest/Beta PM.
Straps/vrtimings, etc. all applied


Thats not true.  1070s are NOT affected by DAG size so far.
All mine are hashing at 30 Mh/s with no problem.

It all depends on your system (power usage, OS, memory, driver...)

You are wrong, every Nvidia Pascal Card, reduce the hashrate with every new DAG epoche. It's the same bug as the AMD R9 290x and R9 390 in the past.
The reduction is not much, but it will happened, You see it, when you let your miner benchmark in epoch 0 and for example in epoch 300. Test it and you will see it dude;)

The user was referring a hashing speed of 22mh/s on a 1070.. and thats not related to DAG size. He has another problem, as i have all my 1070s at almost 30mh/s (@~125w)

I recall reading posts and links to nvidia forums stating that 1070s do indeed have a reduction of total mh/s output due to the DAG size. Forgive me as I don't have the link on hand.

Update: I unplugged everything, tried one gpu at a time and ran at 22.5 mh/s and that one odd at 29  mh/s. I plugged everything back, now all are reporting 29 mh/w and one is stuck at 23 mh/s. Any guesses? Because I have no idea what's going on.

To the other poster, my gpus are running at 65C-70C, it's very cold here and one of the reasons I decided to turn it back on. My settings are +100/600+ @70TDP (I tested up to 80 but there's a tiny bit of increase .5).

Thank you all
