Cards with 4gb memory dont have this issue, at least to me. They reach maximum hashspeed immediately.
The problem is with the 8gb cards.
Whenever I start your miner one of them, sometimes more, can go up to maximum, others no and they stay low all the time
even after 2,3,4 hours of mining.
Next time I'm starting your miner some other cards or card do the opposite thing. It's a random situation.
To help things out, you of course the developer of a great miner to me, I found out that running GPU-Z at the time your miner runs
and passing throu all cards one by one and then exiting, voula all cards running full speed. Problem solved.
But of course this is not a solution!!!
Maybe something with the interrupts?
I'm trying to help!
I wanted to try this, and I got 1000 h/s across the board just by firing up GPU-Z.. Awesome. Wish I had known this earlier! The GPU-Z launch was unusually slow... Very strange! Whatever it is doing to the gpu's, SRB can do too, this gives me hope.
GPU-Z is 2.8.0, and I'm ignoring the update to 2.9.0 in case it works differently, lol.
