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

[rednoW]

New version, good. I will test ASAP.
With 0.4, i have 1834 with MSI Vega 64 (and recommended setting).
Very stable.

Vega64 is now doing 2150h/s xmr with xmr-stak-amd.
1408gpu/1150mem@875mV, approx 150watt

How did you set 1150 for mem?

Hi RednoW,

Have you mod your Vega 56 ? And what is the H/s with consumption that you have ?

Thx

[rednoW]

Vega56 1408/1148 is doing only 1970h/s.
The main drawback here that I need to use lower intensity than with Vega64.
Vega56 is not stable with 2016/1800 setup I use with Vega64

Well that is the inefficient structure of stark. The vega56 can easily do 2000 hashes/s out of the box with 960 mem clock, PL 0 no heavy modding or bios tinkering needed.

Just use cast-xmr

i had runing this miner for 30 hours. its stable. it show more hashrate than xmr-stak. awsome.
this is my vegas mining rig (64@2  56@2)

which win driver version for AMD ?

power limit ??%

gpu clock/mem clock/mV ?


thnx

its block chain driver Aug 23
vega64@2 core 1400 mem 1100 900mv(value is overdriveNTool,GPU-Z show 0.8875mv)
vega56 core 1400 mem 1100 900mv(same upside)
vega56 core 1400 mem 950 (core 900mv mem 800mv) its stock vega 56 bios and softpowerplay reg moded. but i think that it is not ture hashrate. maybe got any hw errors,but i cant monitor that any where in XMR-STAK and this miner.

Ok, I did some tests with your miner with default intensity.
vega64 1408/1150 2070h/s
vega64 1560/1150 2120h/s
vega56 with vega64 bios 1408/1148 2000h/s

Your miner is faster (or shows faster speed) than xmr-stak exactly to the value of your devfee ))

As for the good speed of vega56 with original bios at 960clock - I think it is due to better memory timings in vega56 original bios.

I set up everything but when I run the miner I get the following message: SOCKET ERROR - Connection Error: GetAddrInfo: The specified class was not found.

Anyone have a solution?

This miner has a serious problem for me. It can work only  if there is no my nVIDIA 1070 on the system (with nVIDIA I mining ZCash). Then it says a blockchain driver was not detected. When I removed the nVIDIA 1070 then it works well. What is the problem ?

If im not frong, here described it about 7 times, you need to remove nvidia schedule task.

you should change opencl platform to 1 or 2. Check --help how to do it.

If it's same consumption is perfect.
I love PSU fanless



But i must flash the bios for that ?

Thanks for this, bought a few vega 56's just to play with your miner. I get 1950 H/s but it drops to 1750 every time I start the second vega. Any tips? I wanted to make sure crossfire is disabled but I can't see this option anywhere. This is running on an older AMD 990 FX board with latest updates on Windows 10 and the beta blockchain amd driver.
-edit-
one more question -- is the performance bad with 4gb RAM? I saw you listed 8GB as the requirement. I have 16GB in the machine I'm testing it on now.

You're right, the shares are rejected with reason block expired, it's good to know, thank ypu

Use latest version - it supports multiple gpus in one mining window. You will need adjust bat file accordingly.
By the way I was trying to mix cast_xmr for vega56 and xmr_stak_amd for vega64lc and got the same problem - after starting second process (cast or stak) the first miner losts the speed.
So I have to choose to use cast_xmr or xmr_stak only.

I have 2 vega56, does vega64 bios increase hashrate?

[rednoW]

only if you will oc memory to 1100 and higher. And the increase will be small for xmr. For ETH - much higher.

this post https://www.reddit.com/r/MoneroMining/comments/74hjqn/monero_and_vega_the_definitive_guide/ says

Code:

VEGA 56 with Stock bios: 1800H/s @ 160W 
VEGA 56 with 64 bios:1850H/s @ ~130W

Looks it's worth to use vega64 bios, it this post out of date?
