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

[ntshb]

i've posted about my problems no less than a dozen times and no one has ever helped.

thanks everyone.

[Toughit]

I just added another Vega 64 to my rigs. It was 1xvega 64 and 2x56. Before i got 1800H/s for ea of vega 56. now i only get 1400H/s average. I did all the trick but i couldn't fix it. any advice? thanks

Can you try running each card in a different instance?

Edit your config file and only run card 0
Then edit it again, and run card 1
then card 2 and then card 3

You should have 4 windows.

I had the same problem with 2 cards, low hash rate when run together.
Then I decided to run one card on ETN and the other on XMR, both now get over 1900 when run by themselves.

Interested to know if it works for anyone else

It loooks like this https://imgur.com/a/EdcbA  after  i start cast xmr it works for few seconds then the 2x cards on other psu shuts down

im using https://www.miner-shop.cz/prislusenstvi/psu-2-psu/

tryed changing gpu powers cables to 2x 8pin in vga and 2 x8pin in psu from 2x 8pin in vga and 1 8pin psu it had same effect

I managed to get it work with turning on and off all cards in devices  and also turning on and off hbcc on all cards this makes it work but only for 80 mins  then same thing happens

you don't need to do that. Maybe that cable isn't stable enough and creates some stress on the motherboard. There is a much, much cheaper and energy efficient solution to use 2 PSUs at once --I've seen some miners using a very expensive adaptor to connect 2 PSUs to the same motherboard.   ONE of the PSUs doesn't need to connected to the motherboard at all. Learnt this trick in my first year studying computer science and testing computers, 2 years ago --it was one of the questions in the exam   .

The green and black cable of the the PSU can be bridged using a paper clip, this is meant for the PSU to be tested and check if it works or not. If the fan starts spinning then the PSU is fine (so you check for issues on other componentes).

The EVGAs include a piece of plastic to make that bridge and test the PSUs. You can use that or just the paper clip trick, a bent needle, etc etc etc.

I've always wondered if its a great problem to just have multiple psu and possibly they start at slightly different times but they are all powering the same system.     So say you had alot of hard disks and you put them all on one psu and the other psu powers the rest of the system.   Is that ok to do without it causing a problem and same for the cards, why not just just 1 psu for a bunch of cards and 1 psu to power the motherboard and any other requirements.  

Is a graphics card really not ok ok to split the psu load because some of the power is coming from the slot / riser cable and that has to be exactly synced to the 8 pin power cables.   Im thinking its really not a big deal but I dont especially want to test it and blow up a perfectly good setup or damage it slightly every time its rebooted.  Maybe plug all psus into the same multiple socket extension and its almost dead on (psu age in their capacitors so it would vary some).  More I think about it, Im sure its fine Im just paranoid     But why do people pay so much for >1000w psu, theres definitely a premium.

Its one of the myths that needs to debunked maybe

Hello dear dev!

Any chance version for Fiji would appear in your miner?

I wish I had a chance to test my Fury X with your sick efficient miner

Hi all again!

Anyone using Cast to mine SUMOKOIN?

I mined SUMO for several days at different times at several pools and although Cast is working flawlessly, delivering the same exact hashrate as with other Cryptonight coins, the results at the pools are subpar. I would say that at the pools the "calculated hashrate", averaging 24 hours of effective mining, is around 15/20% less of the hashrate "reported" by the miner.
Normally when I mine XMR, ETN or NiceHash, averaging on 24 hours I get a "calculated hash rate" that is within 2 to 5% of the "reported" one, most of the times in excess.
For SUMO I have used Hashvault Pool, FairPool and Bohemian Pool and all of them gave similar subpar results.
I understand that difficulty in SUMO fluctuate a lot and get very high several times a day, screwing up the daily payout.
I am just wondering what are other people experience.

Yep, same crap here, sumo on pool shows 15-20% less than XMR. Miner related problem. I used cast xmr on nanopool with --fastjobswith and hashes was correct, when use XMR Stak got 10 maybe more % less than cast on nano. Think its miner related. Cant say XMR stak works better with sumo or not. Its working like crap on my rig. So i stay with cast. Also I think its because we cant set fixed difficulty in cast xmr, setting dont work =( sometimes its help and hashes become stable.

Thank you for sharing.

Maybe miner related, but could be likely due to large difficulty changes and servers inefficiency.
Which we can sum it up with crappy pools for Sumo.
If the following video may give a hint on what kind of high tech Sumo pools are relying on....
this is supposedly the best 3rd or 4th Sumo pool out there...
https://www.youtube.com/watch?v=D1RMb9Otems

I do not know if I will find the time to test another miner on a SUMO pool.

[AlexanderDumas]

Is there a way to setup/define backup pools? Don't see a way. That's the only thing keeping me from using Cast XMR.

Go to the dev site, is written in the instructions.

I've done this for a long while and it works well for me, but I expect others will disagree.  I use one PSU, typically an ATX to supply power to the motherboard, SSD is plugged into motherboard, and maybe the same ATX PSU powers one or two GPU cards.  Then I use a server PSU to supply power to the remaining GPUs -- both the riser and the card itself.  When I need to turn off or on, I turn on server PSU first, then ATX; when turning off, I power down ATX first, then the server PSU and yes I do that manually.  Server PSUs are cheaper.  This way both PSUs never go beyond about 50% 60% of their rated limit, which means they should be running more efficiently.

Hello I´m trying to get new rig runing. My 3x vega cards on main PSU are woking fine but whenever i try to run the cards which are supplied by second psu  it runs for  sec and then the second psu and the cards supplied by it shuts down. My main PSu is Evga gold 1000GQ  My second PSu is same brand  but 700w - Evga gold 700GQ which i use to power 4th and 5th card and  their risers(tried to power risers from main psu had the same effect) I can mine on 4th or 5th  vega when launched without the cards on main psu

Is it a PSU problem  ? i also have just 4gb ram but i have enough paging file memory on ssd
 

what cables are you using? I experienced a similar problem trying to connect a couple of Vegas to a 750W PSU which only had 3 8 pin PCIe connectors, so I had to use a 2 8Pin PCIe to 1 8Pin PCIe adaptor, and the PSU run for less than a second because that cable in particular created some kind of short circuit, and the solution was to use another conector, a SATA to PCIe adaptor which did the job quite well.

Anyone figure how to solve the hash rate drop to 1600?

HAhah man read the threadzzzzzzzzz.

Make sure the card is kept as cool as possible, under 70C, shoot for 65C and whatever fan speed works to achieve the needed temps to prevent the card from throttling memory speed. HEAT = BAD

Consider looking up the regedit to reduce power consumption cited many many times previously. Also, there are other tools to check the actual memory temps that are mentioned in the threads here. READ THREADZZZZ = HELPZZZ COMPUTERZZZZ HASHZZZZZ

Make sure you have disabled screen savers and make sure windows is set to never turn the monitor off. Never lock the computer or send it to the lock screen. Just turn off the monitor. SCREENLOCK = BAD

Then you can hash consistently without the long term drops. There are many steps just from here to fine tune the setup for XMR.
POWER HASHZZZ = MONeyEAZZZY

F r crying out loud man!!!

That's the thing, they run at 59C, sometimes for hours, then randomly drop to 1600.

So look up the other tools mentioned in the previous 50 pages of posts that talk about other tools used to check on the actual temps occurring on the memory, which is different from Wattman/Overdriventool. You will need to check that obviously. Also as I mentioned check your windows settings to make sure monitor and HDD or SSD never turn off. Windows settings are just as important.

It's a known issue as discussed on CircusDad's guide here:

http://vega.miningguides.com/#Script

I never personally experienced it running a single Vega 64, but as soon as I added a Vega FE, I began to experience it and I've not found any solution to it other than the hashrate monitor to restart the mining program when it happens.

For me, at least, it is absolutely not temp related. My Vega 64 HBM temp never reaches 70, ever. The FE temp reaches 74-75 and still hashrate doesn't drop, the drop is completely random. It'll be pulling 2150h/s on the FE for 12+ hours @ 75c HBM temp without an issue, then randomly just drop. Then other times it'll drop within 15 min of starting miner, with HBM temps in the mid 60s. Worth mentioning that by default Vega FE has higher temp thresholds than Vega 64, likely due to being a higher binned chip for the professional market, but it also has twice the HBM memory in the same package, so it's gotta be stacked higher, meaning higher temps (its HBM will run 5c higher than the Vega 64 in identical conditions, even as a single card).

Power profile is accounted for. Monitor never goes to sleep. HDDs never turn off. I have done dozens and dozens of hours of sensor logging and there's no correlation between HBM temp and hashrate drop (for me).

I used CastXMR for weeks on the single Vega 64 and never experienced hashrate drop, it was stable @ 2050 for the entire time. Now that I've added the FE and started getting it, I've had to move to using XMR-Stak's new unified miner (don't use the XMT-Stak-AMD as it experiences an extremely high rate of GPU compute errors), which works with the auto-restart/hashrate monitoring tool in CircusDad's guide. Unfortunately, until CastXMR creator adds remote/web monitoring like XMR-Stak has, the software won't work for CastXMR.

Anybody else experiencing hangs? I have 6 x RX Vega 56, cast-xmr hangs every couple of days. It's pretty annoying, I'm not sure what may be causing it.

[ghensai]

How do Ardenalin drivers work if you use them on a setup that has rx570 rx 580 and Vega included?

Any expirience with that?

If you run RX5xx and Vega in the same machine, you need to use Blockchain drivers.

RX5xx run excellently on the latest Adrenaline drivers, if you run them in a system sans Vega cards.

if you want to restart miner x time due hash drop here is simple script .
my miner restart every 30 min
Ps don't close script terminal.
creat bat file and put this.
Edit set commandline and set u config

Code:

@echo off

echo -------------------------------------------------------------------
echo Restart Cast miner every 30 min
echo -------------------------------------------------------------------
echo:

set executable=cast_xmr-vega.exe
set commandline= -S youpoolhere -u youwallet here and others cmd from you bat file. %* --fastjobswitch --forcecompute
set runforseconds=1800
set restartinseconds=2
set /a counter=0
timeout 2
:start
start "cast_xmr-vega" %executable% %commandline%
echo:
echo The software will run for %runforseconds% seconds
timeout %runforseconds%
taskkill /f /im %executable%
echo:
echo Restarting the software in %restartinseconds% seconds (%counter%)
timeout %restartinseconds%
set /a counter+=1
echo:
echo:
goto start

Thanks!! That is awesome stuff. Ever since I plugged 6 Vega either the drivers or the program are less stable and have to restart things over with a bat file, which I use, but it is manual and different than this one. How could your bat file be done to have onedrivetool and devcon.exe settings included too?  

I really want to switch the drivers to the new Adrenalin ones... but it seems like the hash rate is quite slower for Vega 56

here is script to restart video cards , start overdrive and start mining.
juts copy,creat new bat file and edit.
SET MinerOpts -S xmr-eu.dwarfpool.com:9100 -u .... etc
SET VidTool1= OverdriveNTool.exe -r0 -p0Vega56 -r0 -p1Vega56 ... etc
set runforseconds=1800 secs to restart , 30 min default.

sorry but bitcointalk does not let me post the complete script in the code

Nice band-aid. What a waste of time though. You are better to figure out why the hash rate drops.

I have noticed that the hash rate drops in the following instances

1. Windows is not set to "Never Turn Monitor off" on the power settings
2. Making sure that windows never shuts off the HDD or SDD "Always on" in power settings
3. Locking the computer or sending it to the lock screen (drops hash rate instantly) Keep the computer logged in on the desktop!
4. If you can't leave a monitor hooked up to it (tuned off) then find a dummy plug.
5. Using remote desktop and logging off ( Sends computer to lock screen) Even team viewer can cause problems.
6. In some cases running miners on different pools (running multiple instances of CAST) can cause the has rate to drop, meaning its best to use a single instance and point them all at the same pool. Results differ per miner.
7. Using the onboard GPU or iGPU is recommended. Plugging displays into the VEGA mining cards directly is not really recommend but works fine for some. Find another GPU to plugin if you don't have onboard to use as a last resort.
8. Try not to mix cards, as this can cause problems as well unless you really know what you are doing.
9. For 6 Vegas you should have at a minimum of at least 49452 Virtual Memory specified in Windows. A 120GB SSD is fine and so is 4GB of ram to accomplish this, just make sure you have enough space on the drive to do this. Increase by 8GB for each additional card. Windows may display this in MB but it's fine. The math is as follows 1024*(number of vegas)*(8 megabytes/gigabytes - whatever windows)+ (300 for overhead) = 49452
You can probably get away with less but it works so who cares.
10. Boot into safe mode to remove AMD drivers using DDU or even the AMD driver removal tool.
11. Install [Suspicious link removed]pute drivers for VEGA! in normal Windows(not safe mode) Don't install anything you don't need.. like ReLive or Problem report tool... (many different opinions about Wattman. I use it and have no issues)
12. Keep your mining rig configuration simple and focused as possible and you will have few issues.
13. Device manager disable and re-enable VEGA's after every reboot before you start to mine.

Shutting down the miner all the time is a waste of time and money. Spend the time to figure out what is wrong by testing out your rig and finding out what works before using a band aid solution that is not great for mining.

Again, hashrate drop is a known issue as per CircusDad's guide, and nothing you've said above will prevent it from happening to people who are experiencing it.

Also, using remote desktop doesn't cause the severe hashrate drop - I use remote desktop to all my rigs multiple times a day and at worst it causes a slight, temporary drop in the display card's hashrate (no iGPU on the rig, if there was an iGPU it wouldn't cause a drop at all) which goes straight back up once you log out of remote desktop (leaving the rig at login screen).

RX5xx run excellently on the latest Adrenaline drivers, if you run them in a system sans Vega cards.

Is there any advantage to using the Adrenaline drivers though?  Don't you have to go in and turn on Compute mode?  That's an extra step right there.  And does that ever reset and require redoing it?

To be fair, Circusdad is using STAK, with Cast I never experience hash drop rate.

[tlaskows]

Those Vegas are 1000$ per GPU.

This miner does not work with old rx 480s (slow RAM).  I have Windows 7 on my gaming PC.

I compiled XMR stack AMD/CPU from source and 580 H/s on a cheap rx 480 is as good as it gets.

CPU (old Xeon) + 2 slow 480s ~ 1750 h/s stock @ 400 watts from the outlet.

All the other miners were actually slower than the free one.

Its one of the myths that needs to debunked maybe

My understanding is you want to keep the risers and the graphics cards to the same PSU. In a 6 card system put one PSU to have the mobo and 3 card and risers and maybe put the ssd and 3 cards and risers on the other PSU. Also use PCI-E cable to power risers rather than Sata.
