Hi!
I have a Ryzen 1700+Vega 56 on a MSI x370 Carbon Pro Gaming, recently reformated with Windows 10 version 1809, latest mother drivers + Radeon 18.6.1
I have a strange problem. If I start Windows and run Cast right away I get 1750H/s. If I leave it alone for a couple of minutes (?) and then I start Cast again, I get ~1100H/s. I have to restart Windows or suspend/resume Windows to get 1750H/s again.
Is there a way to fix this? Or maybe restart the driver without the need of restarting Windows or suspending/resuming? It's not a Cast problem because I get the same problem with other GPU miners (but not with CPU miners).
I do not want to sound like an axxole, but the causes could be many, and at this point in time with the mining gig so depressed, I doubt you will find anybody with the energy and time to spare and tell you more than what I am going to tell you now:I have a Ryzen 1700+Vega 56 on a MSI x370 Carbon Pro Gaming, recently reformated with Windows 10 version 1809, latest mother drivers + Radeon 18.6.1

It is apparent that you use your PC for gaming and that is fine, I would stick to that and not worry about 200 hashes. Also because with one card only, you are scrapping pennies per day.
No, I use it for mining and a bit of web browsing. And I'm not going down by 200 hashes, but 550. And Every penny here is worth mining because devaluation here has took a big hit on us and even with current "mining gig so depressed" it's still profitable here.
We all went through a lot of troubleshooting which most of it is documented on this thread and you may have to dig it out.
Most of us who run a stable and well performing rig, have a system dedicated with settings suitable only to mining.

I had it. But then I had to reformat and install Windows+drivers+miners again and the problems arose.
It's not that the card can't mine. If I start the computer and put it to mine right away, it gets a almost constant 1750H/s. But if I wait for a couple of minutes or I stop the miner and run it again later, it drops to an almost constant 1100H/s
I've tried looking not only in this thread, but on many other forums. And because this is a problem with any AMD miner, I've asked in other forums.
I give you 2 tips: check if the gpu temperature stays below 70 celsius, because when it goes above 70c sometimes it throttle down or the driver reset itself to specs overclocking on order to protect the card. In that case you need to improve ventilation or GPU fan speed.
I've configured to be t 68c and it stays there...
Then check on your MB BIOS if the GPU setting is on GEN1 or GEN2, which are the best settings for mining. Normally by default the MB are delivered on AUTO. Having MB GPU settings on AUTO normally make the miner decrease HS rate or simply crash.
I'll look at it. One of the things I've done prior formatting is to update BIOS. Maybe that setting has changed.
But remember: miners go OK for DAYS if I start it right away or don't leave it alone. Also restarting or suspending/resuming cure the illnes.
Many thanks! I'll check there too!!
Good luck!
I'll need it...
