Topic: [Cast XMR] high speed XMR/CryptoNight miner for RX Vega GPUs (2 KHash/s) - page 9. (Read 206404 times)

How much of h/s do you get with that trick Germini?

Hello dear mates, I hope this shoots some light to people stuck with this hardfork or people without wanting to use SoftPowerPlayTables

I installed CastXMR v1.5.0 using same drivers 18.4.1 as when using CastXMR 1.4, the day before the hardfork hashing OK
Now the day after hardfork each vega 56 is hashing 800h/s.

Be careful with running all your GPUs for tests because power consumption is increased. For safety run only 1 or 2 to test if overclock/undervolt works fine.

EDIT: No need for ati patch using 18.6.1 also applying overclock takes place without the need to use a dummy overclock before the desired one.

Solution to fix it
1) Uninstalled Adrenalin Drivers v18.4.1 using DDU 18.0.0.2, restart
2) Installed Adrenalin Drivers v18.6.1, restart

After these two steps, overclocks/undervolt overclocking and undervolt is working without soft power tables.Now i'm hashing 7% slower than before and power consumption increased by 13%.

My setup working with overclock and undervolt no need for SoftPowerPlayTables is the following:
don't know if you can get the best undervolt/overclock using this method or using SoftPowerPlayTables, but works fine for me
-CastXMR v1.5.0
-Adrenalin Drivers v18.6.1 settings by default (HBCC comes off by default as well as crossfire is off by default even having more than 1 gpu)
-OverdriveNTool v2.7 beta 4 (http://www.dropbox.com/s/equ297p3otqu28n/OverdriveNTool 0.2.7beta4.7z?dl=1)
-Watchdog script: HashMonitor.ps1 (https://github.com/fiddlefingers/Fiddlefingers-cast_xmr-hashrate-monitor-and-restart-tool/blob/master/HashMonitor.ps1)


Cheers mates

Do i still need the reg mod even for 18.5.1?

The solution is to run a dummy plug.  When I have a monitor plugged in I have the exact same issue.  Put in an hdmi dummy plug. reboot, and its back to normal

I'm kinda same
Adrenalin Driver 18.7.1 (not planning to update until i know is stable)
Using soft power tables(not sure if it really helps)
Cast XMR 1.5.0  (algo 10)
HBCC - have no idea, same as it was for V7, didn't touch it for this fork
power: 4 x vega64 liquid cooled ~860W (was 740W on V7)
Hashrate: 7610H/s (was ~7900H/s on V7)

I think I know why I may be having these issues, its because I'm using a Vega FE.  Anyone else have hash data on Vega FE?

I am using 18.5.1 and i always encounter the code 43 error after applying the reg mod.

Even if i don't apply the reg mod, the vega 56 runs but the fans don't spin at all and it hangs after a while

Thanks a bunch for your continued support. Switching HBCC off worked for me. I was skeptical at first, but you know, I don't quite understand how the inner workings of the miner. Was able to bring my hash from under 900 to under 1800 per Vega 56 with this.

What is ONT?

Can you post a link for everyone so we can look into this ONT.

I am at 1850 after some tweaks with ONT

Installed 18.5.1 and now getting 1650 h/s

I'm in the same boat.

I tried 18.5.1 and 18.6.1 drivers and they both give me around 800 h/s.  I was getting 1850 h/s previously.  I have HBCC=off Large pages=ON. 

I'm sad

same thing

I had the same problem when changing to V7, at the time I set the right Algo and got 100% accepted...
This time, I did even try the Autodetect Algo (-1), I put the 10 algo and everything went ok...

I've also been having issues after the fork. The systems I got working are all hashing around 100-200 sols less than before. And some dont even begin. Been troubleshooting all morning long and slowly making progress. You just got to check everything. Check your drivers, your windows version, and your bat files. Have you guys been trying other drivers? I'm using 18.5.1

I always used the radeon software to configure everything but now i am considering using power table to optimize performance since the gap has gotten a lot bigger.

Hey Guys,
I managed to process through the network upgrade flawlessly.
After the initial block, I stopped mining CryptoNightV7 and ran an updated bat file.
I use NiceHash and the only thing I needed to do was to change a server address and port.

Overall my hashrate dropped around 5% and power consumption increased up to 25W more for a single card (8% increase).

Adrenalin Driver 18.10.1
HBCC Off
Cast XMR 1.5.0

hello guys,i switched from the old version of cast-xmr to the new 1.5.0, did not change the startup parameters, everything was the same, only the exe file was replaced, and the hashrate decreased from 1900h / s to 800 h / s, help to understand what the problem is? HBCC on

I turned my rig to v8 and getting around %6-8 more "share above target" error with same settings of v7.. is there a way to fix it? anyone having same issue?

(because of high of this error, i changed my rig back to cryptonight heavy for better profit.. i got %100 accepted shares with crypthonight heavy with same settings )

Without the OverdriveNTool, directly on AMD Software,

Vega 56 -> -2 power, -2 core, @950   1860 H/s
Vega 64 -> -3 power -3 core, @1025  1800 H/s

But yes, more power and less H/s, wich means less Profit

Sure you are on the AMD GPU Pro driver not the Rocm version?

Did you install the driver with:

./amdgpu-pro-install -y --opencl=pal

?
