Topic: [Cast XMR] high speed XMR/CryptoNight miner for RX Vega GPUs (2 KHash/s) - page 94. (Read 206388 times)

cast_xmr-vega -S pool.supportxmr.com:5555 -u yourwallet -p x --nonicehash -G 0,1,2,3,4

--nonicehash is optional, -G will depend on the amount of cards you have. In my case, I have 5 cards.

Could someone post their exact .bat info please. I'm having hell with this miner. It will not connect to ANY pool, and I thought the .bat was correct.

Examples tried:
cryptonight.usa.nicehash.com:3355 -u 3K6N9sqGvZRp5FRr5ioAo4HC824duhSsuj.PC
cryptonight.usa.nicehash.com:3355 -u 3K6N9sqGvZRp5FRr5ioAo4HC824duhSsuj.PC -p x

If it connects I'll mine to your address for a while. I've checked my AV and it nor Windows Security claims to be blocking it, but who knows. Claymore connects, but is only 1300h/s, so I wanted to try Cast.

Sapphire RX Vega 64 liquid cooled, ASUS Maximus Hero, i7 8700k, 16gb RAM, two Samsung 960 EVO 250gb in RAID 0, Win10 Pro, Afterburner only has MC adjusted to 1100, Adrenalin 17.12.1

Yes, it happens to me too. For what I read, Asus Z270-a is not the best mobo to run Vegas. I'm changing it tomorrow. Will let you know if it get more stable.

My rigs would run fine for hours and then out of the blue Cast XMR hangs. I have JJs monitoring script running and because the values can be read from JSON it doesn't pick it up as a hang. Essentially the timestamp remains stagnant, bolded below, with no additional increments. Only solution is to force the Cast window closed and let the monitoring script restart the Cast cmd shell instance.

[16:36:35] GPU0 | 51°C | Fan 3245 RPM | 1913.2 H/s

I know I can modify the hash monitor script to do a check on the timestamp.

Anyone else seen this type of issue?


I have 2 rigs with the following config:
4GB Corsair RAM
ASUS Z270-a mobo
3 x Vega 56 stock bios, memclock at 920mhz for all

nice numbers.. At which speed does XMR Kast mine?

I have no experience with the Vega 64, but for the looks of it, you might need to find the sweet spot for your Vega 64, MHz wise. Vega 56 sweet spot is around 930-935MHz, again, from personal experience, this might differ.

At anything above 940MHz, if I set a Vega as the main GPU, everything seems normal in your OS' desktop, but then after doing something as simple as using GPU-Z to check stats, screen artefacts start to show everywhere on the screen, like when you overclocked a card too much.

Using Cast XMR alone seems fine, though, your OS' desktop won't show artefacts and the cards will be running, BUT I got random hangs so I used a 10 minutes timer to restart Cast XMR and OnedriveNTool, and you get more errors. It's been 2 days the 6 Vega 56 rig is running stable and the difference is night and day, you can sleep well.

Also overclocking can lead to de-configuration of your card's settings, as if the card forget their own settings which you had set up at startup, and can get over 80º with the fan spinning at something like 1000rpm and be happy with it --this means the card can wear off and not last much.

I have 3 Vegas 64 on that specific rig, all have 1100Mhz power table.

GPU section:

State 6: 1212Mhz - 900mV
State 7: 1407Mhz - 905mV

Memory Section:

State 3: 1100Mhz - 900mV

confirmed 662 shares 0 errors (2 hours) at 11600H/s average on 6 Vega 56 cards with these OverdriveNTool settings:

fastswitch sounds interesting, although I never used it, I gotta give it a try if I ever see errors. I have the cards running 100% stable now at the OverdriveNTool settings below, and to give you and idea, I get 480 shares with 0 errors every 1 hour 27 minutes (not a very orthodox number but that's the number that comes to my mind now). This is my OverdriveNTool.ini file (dont like AMD Settings utility much, both in the Vega rig and in my desktop computer with a RX 570):

I restart the miner and OverdriveNTool every 4 hours, for security reasons (the overall process takes 3 seconds. AMD drivers seem to sometimes forget the Vega 56 settings, whatever the reason, happened to me once or twice, and it's not fun, 'cos one of the Vegas can get really hot and the fan spins at slower speed than the minimum you've set.

I think it is the other way around.
Cast is 1.5% donation and STAK is 2%.

At least on my case, --fastswitch may have lowered the reporting of Hs rate on the miner window, but it has actually increased the rate on the pool monitor, which is what matter at the end, since it is how we get paid.

Now I have been getting 9000Hs for the last 24 hours, on 4 Vega and one 580, at 830w at the wall. Before I was getting 8400Hs maximum.
It tend to lower the Hs rate if it runs without auto restarting for more than 2 hours, but if i put it on 60/90 minutes cycles, it keeps the average at 9000hs for 24 hours.
On the miner screen it shows 8650Hs yet at the pool I get 9000Hs.
I cannot complain....

For the Vegas these are the settings:

I have set up the rig using most of Circus Daddy's Vega Mining guide

Blockchain drivers august 23

1 vega 64
3 vega 56  bios 64

Regedit Power table 1100Mhz

P6 1212   890
P7 1408   890

P3 1100  870

Power 0%
Max temp and Target temp at 75
Fans at 2800, 4900


Cast has also lifted Hs rate on another PC on which I run 2 of RX580 and Andrenalin drivers. It run steady at 1900/2000Hs on both XMR and ETN, without any crashing. before I was only reaching 1750Hs for both 580 cards.
On the miner screen it shows a combined Hs rate of 1664Hs for both cards, yet at the pool I get 2000Hs.

I finally got it to run reliably.
I hope you get better luck.

more or less the same here. I cannot bother changing the BIOS, after talking about it, so I use OverdriveNTool with the settings I shared before, and it is incredibly stable now, both the program and the cards can be the entire day working at full speed, except if I get an internet connection error. Average hashrate of 6 Vega 56 is 11500H/s approx.

which settings do you use? What's the speed of your Vega (56 or 64?) cards?

From personal experience, this program is slightly faster, and also more sensitive to changes or it pushes the Vegas a little more. If you have Vega 56 cards try to set them at 935MHz or slightly below, mining speed should be around 1920-1950 H/s, which is pretty good and they are 100% stable.

I've shown the settings I use before and I am getting 0 errors every 2 hours. This is a screenshot after exactly 1 hour (59 minutes 20 seconds) of mining:

Youre not the only one circusdad also got those error reports. I might have to try this for a week and see which miner is stable.

I really wanted to use this miner but it has a flaw… I’ve been using it for the past 3 weeks and I’ve been getting 10% submission errors… For now the XMR Stak is more stable for me with only 0.02% submission errors…

I’ve even tried using the —fastswitch feature but that lowers my hash rate by almost 200H\s per card… Plus, this one is 2% dev donation as opposed to Stak which is 1% and more stable…

 The reference cards should all be the same, as the guts are entirely provided by AMD.

 Aftermarket cards will vary a LOT though - like that Sapphire Nitro+ model with the INSANE 3 power connector setup.


 My single STOCK Vega 56 gets 1940-1950 consistantly long-term, I've not bothered playing with the BIOS as I'm not sure how long it's going to be pointed at Monero mining and it doesn't NEED a modded BIOS for it's later "long-term" home.

1. I get the hash rate as long as I have CAST XMR running which is 24/7. I look at the miners about once a day. The only time the hash rate goes down is if I lose connection or turn it off.
2. I don't use OverdriveN tool i use wattman to set the fan speed and target/max temps
3. In the thread above I posted links to youtube that you can follow.
4. HBM 1100Mhz, SOC 1200Mhz, Mem power 900mv

My 6 card Vega 64 rig gets an average of 11,970 hash rate 24/7

I have posted many times on here about all that needs to be done to achieve consistent has rates. You can get the power play tables from the video here

Power Play Tables
https://www.youtube.com/watch?v=cdfjSVE5fvE&t=1s
 

Do you get those Hs rates for a prolonged period of time, or just for a few minutes?
to state that a card Hs at XXX it should average the rate for at least 6 hours.   
Would you be so kind to share OverdriveNT settings and which power table are you using?

I also have 3 of Vega 56 with Bios 64 and a "real" Vega 64, but they get shy of 1950Hs each.
Sometime they shoot 1 or 2 lines at 2300 Hs but that does not count.

Thank you!

New version 8 works with my rx 4 and 5 mess. Now I can try clock them some ....THANK YOU SO MUCH AND MERRY CHRISTMAS!

ah ok, thanks! I know that guy but hadn't seen the Vega bios mod video you shared. As I said, the Vegas aren't mine and that's the step I am most fearful to take, so I am going to talk to the owner of the rig and see what happens. Things are running fully stable now, although I am curious about power consumption. cheers!

I have 5 Vega 56 running at 9950 H/s. Flashed Vega 64 bios and power play tables.

I am currently into a 2 hours restart cycle and as things get more and more stable like they've been for the last 24 hours ever since I made it fully stable (have been resetting the OverdriveNTool values every 45 minutes or so), I am going to increase the timer to 4 or more hours --the restart takes 3 seconds, 2 to remove Cast XMR process, 1 to set up OverdriveNTool options and restart Cast XMR.

Average hashrate for the last 6 hours have been 11,544.1 H/s, not bad for a 6 Vega 56 rig running at 935MHz. Temps are fine, too.
