I'm running a Vega 56 with stock BIOS.   Using Cast I have achieved a steady 1956 H/s for more than 24 hours sometimes.  Other times it will drop to 1700ish and will require a restart of the miner and sometimes reapplying the OverdriveNTool settings.  I am thinking of putting in an auto restart every hour or two and see how that goes.

Please deinstall driver with, DDU and after that, reinstall blockchain driver.
If Win10, you must deactivate with reg or group policy updating drivers from Windows Update, because it will update automaticly your driver

Most likely caused by temps climbing up.
Increase min fan rpm to 3500 or more if in warm environment.

just use the opencl command, try 0, 1, 2, whatever works.  This has been posted in previous pages but the subject comes around quite often...

No there is an issue with the driver itself, but there is a workaround for 6+ GPUs (driver reset with devcon.exe).
My 6 GPU Vega rigs running fine @ 11700h/s @ ~1080W

respectfully  glph3k add support to all AMD cards in your assembly, preferably new ones starting from px56, for example I have one 560 (as a manager) and while one is still a VEGA but I plan another 5. It would be very convenient to use one miner.

im running 4x 56 with stock bios
-20 power limit
-10 power
950mem
3000 fan speed

two hard hit 60 deg, while other two stay at 50.

i have 2x1000w evga s2, and those two cards are on the psu with jumper.

could this be like a undervolt proection from psu which is driving the power up regardless of input?

I'm having similar speed issues to what several others are seeing:

When I START the application, I get a tight grouping of speeds between ~2030 H/s - quite consistent.

After a few minutes, the rate drops to ~1850 H/s, and stays there until I restart the app.

When I restart it, it goes back to 2030 H/s for a few minutes, before dropping again.

*snip*

Okay, I have more details:

* I'm getting between 2030-2040 H/s with my Vega now.

* If I open GPU-Z OR my monitor goes to SLEEP, my hashrate drops to 1850 H/s

* I have turned on performance mode (power) and turned OFF monitor sleep, and it STAYS at 2040 H/s if I simply power off the monitor.

Obviously the answer is 1) Don't open GPU-Z and 2) Disable sleep and just power off the monitor.

Just wondering if there was a way to get that information out there more openly!

hey, does CAST work properly on GPUs connected via risers (1X to 16X) or only on 8X and 16X PCIe mobo lines?

second, could we, please, please, get a Linux version ASAP as competitor's soft (cough-CM-cough) does not work on Vega's running on Linux.

How do I know-I tried, even with the ROCm kernel (run out of things to try).

Is it normal to have such drops of the hashrate? Any idea what is causing em and how to fix?


Actually, I think that I've now developed this problem aswell. Now that my hashrates are back up to full, every 6th report or so is in the mid 1900s, before coming back up.

It seems to come and go though, I'm watching my reporting right now, and it's not happening.

I'll observe my new 24 hour average to see where I sit, and I'll report back.

Is glph3k still around?

All my Vega's connected via risers and CAST work good.

I turn off the display that is connected to my rig and connect to the rig via RDP session. I start cast-xmr within the RDP session and never facing with such problems. Give it a try and you will see.

I can confirm that one reason for performance drop is that the monitor (if any) connected to a mining card, turns off according to power settings.
I have been testing this for 2 days now and the problem goes away if monitor is set to "never turn off".

I have been mining directly to Nicehash with 2 stock Rx 480 8GB GPUs using this miner for about 20 hours now and it's been very smooth. I've only had 1 rejected share in that entire time and it's not disconnecting or getting stratum interrupts frequently (hardly at all in fact) like SGMiner and Claymore were for me.  The hashrate is a touch lower then SGminer at stock settings, but the stability makes up for it.
