[Cast XMR] high speed XMR/CryptoNight miner for RX Vega GPUs (2 KHash/s)

[Fgomes87]

Hi there. I installed yesterday this miner and I notice something strange... (Or not).
 yesterday night i left the computer mining with it. It actually started very good.
 Using xmr-stack I get 4700h/s using 800w.
 Cast-xmr was getting me 5200h/s using 830w.
Good enough for me.
 But when I woke up in the morning it was mining at 4700h/s using 780w.
Anyway its still using a little bit less power to mine the same.
Today in the afternoon i got some messages in my email saying miner disconnected. And my hashrate for the last 6 hours was awful.

MY setup is Intel core i3 4330
5x RX580
1x RX470
Motherboard asrock h81 btc 2.0
Psu be quiet  dark power pro 1200w platinum
8GB crucial ballistix smart tracer 1866mhz
Virtual memory 32gb (using 7gb) overkill of course
Blockchain drivers from 23rd August.
Now it's mining at 5109h/s using 820w
I had to restart my PC 2 or 3 times to get here. Let's see if it falls down later.

Any guesses?

Just by writing this message I can see something.
Everytime it appears share accepted,  the hashrate is decreased by 1 so now its already 5095.

Tried to get my 580/480 8 card rig to run smooth and couldn't get all the zero's out of the miner like it was trying to run about 4x faster than needed even though I was pulling in 6500 hash I had a real bad reject rate I couldn't solve either. Pissed me off ordered some vega 56 pointed Hashington at ETC. i did notice it to seem a little better if I closed out wattman before open cast and do nothing else with the computer. Don't even look at it lol Now im installing 220 to power the pdu strip. Hope this works better. I tried fresh install windows all the other stuff

[crocozino]

well, my vega 56 almost came, but I see already that my plans to put it into the rig of 1080 ti are vanished
so I ordered separate rig for that with Ryzen 7 1700, will build 4 x vega build step by step
i think it would be better and more stable build

As far as I observed, memory error rates are important in pool share rejections for RX cards. At least this was the case for me in ETH/DUAL mining. 
Try to find good settings/bios mods for RX cards which cause 0 or only a few memory error counts. You can check it for each GPU with HWInfo.

Don't bother running this on RX 4x0/5x0 cards, it's not optimized for them.
I works on some, and goes bad on others.
Just use SGminer GM and ur life will be easier

Hi,

I have a new problem whem i start Cast XMR it says:

Code:

Selected OpenCL device index 1 doesn't exist. 

If i look into regedit i see:

Code:

0000 Internal gpu
0001 Radeon RX Vega
0002 Radeon RX Vega
0003 Radeon RX Vega
0004-Radeon RX Vega

run.bat

Code:

cast_xmr-vega -G 1,2,3,4 -S pool.supportxmr.com:7777 -u wallet-address %*

How i can fix this issue?

[greencow]

Any release that (more or less) for a linux version?

[fabry1999]

Do you know why after few hours of mining with Vega56 the hashrate decrease from 1850 to 1600 ?

I have do disable and re-enable the card every time in order to get full hashrate !

try these values for the -G value: -G 0,1,2,3 don't worry it won't use the iGPU for mining...

check your windows power settings, it can cause hashrate drop... quote from http://vega.miningguides.com/
        POWER SETTINGS: Set screen and Hard Drive to never sleep
        Windows Start button: type "run" (or press Windows logo key + R)
        Type:  "powercfg.cpL"
        Select "Change plan settings" for the plan that is selected
        Set "Turn off the display" to "Never"
        Set "Put the computer to sleep" to "Never"
        Select "Change advanced power settings"
        Expand "Hard disk" and set "Turn off hard disk after" to "0"
        Select "Apply", then "OK" and then "Save Changes"
        Close window
        (Note: Setting hard drive to never sleep is thought to help prevent hash-rate drops when the miner is using virtual memory)

I have followed this guide but the problem is the same

[erittainvarma]

Any plans to include support for Fiji or Hawaii cards?

Add this to the bat file:

Code:

--opencl 1 -G 0,1,2,..,N 

for a N+1 number of Vega GPUs.

Ok it starts with cast_xmr-vega --opencl 1 -G 0,1,2,3,N -S

Now i get the follow error

did you have other GPUs on your system before? because it looks like you have driver issue.. if yes you should remove the old ones with DDU...
