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

[CreamyG31337]

works fine - as good as XMR-Stak on my Vega 56's. I will use your software on that rig to support your development. On my random RX card rig, I have to stick with XMR-Stak because the Cast-XMR has some issue with the 470 card. It's only getting about 100 H/s with Cast, but Stak is able to do about 4x that.

The best XMR-Stak settings for the 4GB cards I've found is as follows:

Code:

  { "index" : 3,
    "intensity" : 896, "worksize" : 8,
    "affine_to_cpu" : false, "strided_index" : 1, "mem_chunk" : 2,
    "comp_mode" : true
  },
  { "index" : 3,
    "intensity" : 896, "worksize" : 8,
    "affine_to_cpu" : false, "strided_index" : 1, "mem_chunk" : 2,
    "comp_mode" : true
  },

intensity 960 works better for 8GB cards.
Hope that information can help you improve this.

Hello guys,

i am new there. I have 3 gpu AMD RX VEGA 64.  All times when i am start mining with all 3 gpu my pc crash and restart. With 2 gpu its all ok (i try GPU0 with GPU1 -> OK, GPU0 and GPU2 -> OK, GPU1 and GPU2 -> OK). Only if i run GPU0 GPU1 GPU2 togheter than PC turn off and restart.

Can you help me with this problem? 

I was update new bios and set up like this - https://www.youtube.com/watch?v=4cd1qoTAHmA.

PSU too weak?

Why am I getting so many bad shares???

Wrong algo....

Please explain?

I am running vega56s and mining XMR

You`ve selected the wrong algo to mine this coin, probably Cryptonightt. The right one is Monero7!

Select the right algo and try again.

I really wish I knew what you are saying.  Im on V7...

Check which GPU is submitting invalid and dial back the memory OC until it doesnt.  Also one of your GPU's is 74c, try to keep them all under 70c which in turn keeps HBM temps low.

I think it has to do with Cast Xmr Ui.  I am going to upgrade to the latest and see if that does the trick.  I don't think it was selecting the right algo as mentioned above.  Hoping the upgrade provides a fix

If it could help the developers, I see that my 2 Vega 64 that have low hashrate (150h/s) when mining cryptonight-heavy is recognized as gfx901. The others that is recognized as gfx900 has normal hashrate (1600h/s).

Hi,

that is indeed an interessting info! That is probably the reason for the bugger.

gfx900 means that HBCC memory is turned off
gfx901 means that HBCC memory is turned on

Please try to turn off HBCC memory on all cards.

Today I tried mining Monero with the new CryptoNightV7 algo for the first time but I only get "low difficulty share" errors and can't seem to fix it.

I tried setting the algo manually and also let Cast XMR auto select but neither fixed it.

If I'm mining a coin with the old CryptoNight algo everything works fine, can anyone help me?

will you be adding cryptonight lite v7?

[glph3k]

will you be adding cryptonight lite v7?

Yes, working on it.

[ofpcarnage]

nice one!!!

Also I dont suppose you have add extra features ...such as the ability to keep a track on all your rigs like claymores miner and have it so you can set the rigs to auto reboot and continue mining if a card hangs ?

I 2nd this, I need to mine some TRTL...

Hello, i have this problem:

Can someone help me ?

When i run separatly:
https://ibb.co/iQoNE7

I have 3x RX VEGA 640. So different H/s.. and errors when i turn off all 3 GPUs.

add this to scrypt :  --algo=-1

[AlexanderDumas]

will you be adding cryptonight lite v7?

it is already available with:  --algo=1

[ofpcarnage]

will you be adding cryptonight lite v7?

it is already available with:  --algo=1

--algo=1 for CryptoNightV7  this is not CryptoNight_Litev7    there is a difference

I've been receiving huge ammount of "Share above target" errors for several days mining on nicehash. New version doesn't help. Tried different algorithm switches with no result. Migrating back to nicehash miner.

Hi,

problem on nicehash could be the switch of Graft (GRFT), the PoW change seems hanging between CryptoNight and CryptoNightV7.

Also IPBC switched from classic CryptoNight to a new CryptoNight variant (yes, support is planned).

Seems currently hard for Nicehash to keep their streams clean with all the forking and pool updates.

Thanks a lot this worked but what am I missing? Thought it's supposed to be --algo=1 and not --algo=-1?

my first gpu hash rate drop but 2nd gpu normal. i use 2x vega 64. How can I fix?

system: windows 10 - no amd software, just blockchain drive.

gpu 1 890 h/s and screen tingling
gpu 2 1540 h/s ok.

I'm getting just under 800h/s per RX570 clocked at 1220/1900 with the following command line using 0.9.6:

cast_xmr-vega -I 0 -S europe.cryptonight-hub.miningpoolhub.com:17024 -u xxx.yyy -p x -R --nonicehash --fastjobswitch -G 0,1,2,3,4,5,6

Anything I could do to improve? Setting --forcecompute just cuts the hashrate in half...
