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

[cristian13]

Yeah, i know the steps, but i am looking for other power play tables because the ones that i used on blockchain drivers, dont work with the latest, i get driver signature issue.

Try using the 85% ones from Phase 2 of the FAQ section of the following guides.

http://vega.miningguides.com/p/faq.html#TDRFailure

I'm on the latest driver version and they work just fine.

Thanks, ill give a try and ill update.

I put the driver adrenalin 18,3,4 and get it lower hash
With blockchain driver a get 862h with rx580 and now 490h
Vega still not working
With the Vegas after a while disconnecting from pool and reconnect again and again

It's impossible get 1900h/s with criptonight heavy?

Edit:
I'm using xmrig and it gets 1300/1400h/s each Vega 56 without problem and 700h/s with 580!
Sumokoin!!!

That's as high as you're going to get with cn-heavy for now, same with xmr stak.

The xmr stak dev says it's related to cn-heavy using twice as much memory & the Vegas having crappy driver support.

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

Select the right algo and try again.

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 have quickly tested the Cryptonight "algo 2" Cryptonight heavy on my rigs.
The one using RX580 works flawlessly at 910hs per card, which is actually higher than they normally run on V7 (865hs).
Almost too good to be true, but it just works like that. The Hs rate at the pool are in line with the one on the miner.

But unfortunately on the rig with Vega reference cards, I have few cards working as expected at 1450 Hs but 2 of them (one 64 and one 56 bios mod) run at below 600hs, sometime they drop at 200hs.
So for the moment I stick with algo 1 and XMR, on which all vegas run flawlessly and a tad faster than version 9.02.

But thanks to Gandalph for providing this new version so quickly.

i try mining havencoin with 0.9.5 --algo 2
and i have problem with shappire nitro rx580 4gb mod bios
my hashrate drop, i just get 140 h/s
i try use driver blockchain and addrenaline... this is same
normaly, i get 900 h/s
what wrong with me sir...?
thanks

[neppers]

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,

there is an update of Cast XMR available.

Cast XMR now supports CryptoNight-Heavy.

CryptoNight Heavy is different, the read/writes are smaller but use a larger "scratch pad" so the hash rates are not comparable with classic CryptoNight.

Here are some first performance values (tested with 18.3.4 drivers):

Vega 56  945 MemClk: 1450 Heavy Hashes/s
Vega 64 1025 MemClk: 1550 Heavy Hashes/s
Vega FE 1025 MemClk: 1640 Heavy Hashes/s
RX 570 Compute Mode: 850 Heavy Hashes/s (Polaris picks up!)

Cast XMR Version 0.9.5 (2018/04/14)
  - 0.5% performance improvement for the CryptoNightV7 kernel
  - support for CryptoNight Heavy set --algo=2 to mine:
    - Sumokoin (SUMO)
    - Haven (XHV)

Download Cast XMR 0.9.5 for Windows (64bit)

Please share PowerTable and Msi Afterburner or overdriveNtool. I'm running Vega 64 but hashrate low.

Confirm Blockchain driver not work

I used  overdriveNtool but  OC didnt worked. Hash for 6 vega 56 are about 7.7khz/s. I used driver  Radeon Driver 18.3.4 for Cryptonight heavy

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.

40G virtual memory is not enough for 6x 580 8G?my god,my hard driver has only 60G....

[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.

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.
