so this is working only with 1 gpu?

1 GPU per instance, yes.

But you can run as many instances as you like.

So start a new terminal and run "cast_xmr -S [server] -u [wallet address] -G 1" to start a second instance mining on your second GPU and so on for 3rd GPU....

and the hashrates are same? Can anyone tell the hashrate on card with not enabled HBCC?

Good job, better performance than Dagger, profit is better with one Vega 64.
I got 1877H/s with the followed setting with my MSI Vega 64.

    Core Frequency: -10.5%
    Memory Clock: 1025 MHz
    Power Limit: -23%

Don't know if i must adjust this, or just close all, or anything else.

Sometime i got 1900, but never 2000. The power consumption is not my first priority, just get the best hashrate.


About consumption, i check without miner, 285W (for the total of PC) during mining, 460W. So 175W at full ??

Only supporting single GPU per instance is a huge issue.  Also, do you plan on adding an api, or at least remote webpage?

Ok, planning to support multiple GPU per instance. Personally found that running on instance per GPU very stable and more flexible, but there seem some reports that it does influence the other GPUs. Should be no big deal to implement.

Which kind of API would you suggest? Is there an standard?

For API, anything really, perhaps similar to claymores, ccminer or sgminer.  JSON data for hashrates, temperatures, fans, pool, stale%, uptime etc. Then it could be added to AwesomeMiner.

Ok, maybe the Vega gets to hot, it has the habit to throttle down if it gets close to 70°. So to stay above 1900 you can increase the fan speed.
Flick the "Speed (RPM)" toggle an enter a value for min fan speed like 1200 and apply, the temperature should drop.

If you want to go for the 2000 and more you have to go all in. Turn up the min fan speed to "3000" RPM. Crank up memory clock to 1100 and increase power limit in steps, core frequency can stay. It gets really loud but you should reach 2000 hash/s and it will eat up another 50-100 watts. My suggestion of the above values are in my opinion the most efficient ones, but if you don't care about the power usage it is worth a try.

Also  one can edit the Voltage Control down, there are some threads where the experts are debating what the best settings are to bring the wattage down again... but please do on your own risk Smiley

do you have a version that will run without the blockchain drivers?... or at least remove the hard block of requiring the blockchain drivers?

thanks

What are the settings of the vega in your screenshot?

The screenshot shows a Sapphire Vega 56 with following settings:

Core clock: -5%
MemClock: 990 Mhz
PowerLimit: +24
Fan Min Speed: 3000 RPM

The voltage control is still on auto.

The GPU consumes 260 watts.

OK thanks you.
The power usage is very reasonable. After one night, it stay at 1824 and very stable. 450W for total, and my PSU (Corsair) is in fanless, incredible.
74C for temp, 85 for HBM


I will try your setting, but if i ear the fan after, and lost 50W, not sure it's good for 100H....
Like i said, the power usage is not the key for me, but i prefer to care my Vega, and no noise Cheesy


One thing too, on Win 10, i have problem after hours mining on the desktop, displaying problem...

THe limit setting was power limit.
I got 1950H/S now, with 520W instead 450. (1100 for mem)
I got 2000 with +5 power limit and 1100.

I will stay at 1824 i think Cheesy

I'm experiencing high rejected shares with your miner, currently on 12 rejected shares with 167 accepted, is that common or maybe you have any insight?
My setting is a low noise one with -40% Powlim, -100 mV through recent afterburner update, and 800Mhz Mcloclk with 1584 H/s avg and 1700 peak,

My setting is a low noise one with -40% Powlim, -100 mV through recent afterburner update, and 800Mhz Mcloclk with 1584 H/s avg and 1700 peak,

Are the rejected shortly (1-2 seconds) after a new job was received? Something like this:


[08:11:00] New job received. Avg Job Time: 15.7 sec
[08:11:00] Difficulty changed. Now: 40000.
[08:11:01] Found Nonce, submitting...
[08:11:01] !Rejected, Nonce Invalid!


Then the reason is that there is already a new job and the calculated nonce are from the previous job.
A roundtrip takes 1-2 seconds in the GPU, an improvement would be to faster cancel the current job and throw the old results away. Currently it tries to submit them. Will try to fix in the next update.

Not sure what I'm doing wrong here,

Windows 10 64 bit
16gb ram DDR3
SSD virtual memory to 60gb
latest blockchain drivers, uninstall and reinstalled 3 times with DDU
1 single vega 56...

Seems to keep rejecting every share on any xmr pool...
