Updated on February 1st, 2018 to version 0.8.5

http://www.gandalph3000.com/download/cast_xmr-vega-win64_085.zip

Cast XMR Version 0.8.5 (2018/2/1)
1% performance gain for Vega Frontier Edition with Blockchain driver (fastest GPU around)
1% performance improvement with current stock driver (18.1.1) for RX Vega 56/64 (40% to go to reach Blockchain driver)
fix for random blocking console output
GPU now always logs with its device id not the order they are listed in the -G argument
--log option to log output to a file
remote access includes CORS support in HTTP header

Where did this come from? It's not mentioned on the front page of this thread or on the G3K website.

Edit: Okay, I see he edited one post of his website, but not the most recent one. Very confusing.
Also confirmed via Twitter.

Great, thank you for you work!

I get slightly higher h/s with this miner than xmr stak for my vegas Cheesy

I wonder if we ever will get updated blockchain drivers from AMD...prolly not.

Does anyone know if theres a hashratescript for this miner too like the jj script for xmr stak?

Cheers,

0.8.5 Still hanging once every few days for me. Not sure if it's a problem with the miner or maybe one of my cards?

Does it freeze with other miners? What are your card settings for power and mem speed?

it freezes just the miner, PC works fine... atleast for me.

anyone knows how to add this to xmr cast:

Went from 0.8.1 to 0.8.5.  I notice a very slight bump in hash rate around +50mh/s, and also a increase in temperature from of about +2°C.

I'm running these cards in low power, aiming for a hash around 1850mh/s, so I don't see any stability changes.

I had installed the new 8.05 but did not reboot and I had 1 freeze after few hours, which may have been caused by my wifi disconnecting.

After reboot it has been working for more than 48 hours without interruptions.
I think it will be ok.

I downloaded 0.8.5
I extracted the miner
I copied my current batch scripts over to the new directory for the 0.8.5 miner
I created new shortcuts to the desktop
I hit q on the current miner and let the current miner shutdown
I doubleclicked the new shortcut
I saw the miner working
I turned off the monitor and went to work
I checked the mining site and I am still making money a little bit more than yesterday (averaging just around 12K h/s)

Hey guys, could you please tell me why the miner is recognizing only 1 GPU? I have 5 GPUs and only this cryptonight miner does not recognize them all :X I am running 5x580 saph nitros+. I looked into the conf file, but everything seems to be A-OK with it...

Yes, there is.  Go back earlier in this thread and look for StellarX88's postings. He modified the Jericho Jones script so that it works just fine with Cast.   He posted the download links to his files.

Serious question for glph3K:

Why does the Blockchain driver provide increased performance over the Adrenaline drivers with the compute option toggled?
https://community.amd.com/thread/221930

It is concerning that there has been no improvement for cryptonight based mining on the Vega with the latest drivers, and AMD coming out and saying that the Adrenaline drivers are "already optimized for the Vega" is hugely disappointing. In short, without the August blockchain drivers we would never have this performance for cryptonight, which I know I am not the first person to ponder this issue.

Do you have any insights on this issue? Have you had any contact with AMD driver developers?

I am not a conspiracy type person but I find this completely crazy, odd and so on...

This also does not bode well for NAVI cards using GDDR6 as AMD may never allow true mining performance to be recognized via the driver. Right now the Blockchain compute drivers look like either a fluke, mistake or some devious ploy to deny. If you have a reference AMD vega 64 you should consider yourself very lucky.

Any thoughts??

Very good questions...and thoughts!
Would be very interesting to get some insight why the blockchain driver is so much better.

Sorry, I can also only speculate as programming with OpenCL and CGN assembler only allows to optimize what a kernel does and to some degree how the kernels are organized and scheduled.

On driver level the scheduling of kernels is implemented also on driver level probably the bandwidth of memory can be influenced as not only the CGNs need access to memory but also the other parts of the GPU that do the actual graphics rendering. Random access memory bandwidth (not compute) is for CryptoNight the limiting factor, as the algo is mainly reading and writing to random parts of memory.

So if I would make a driver for compute only stuff I would give the CGN kernels higher priority and max memory bandwidth and thereby slow the graphics rendering. Which can be experienced with the blockchain driver.

Can only guess if the AMD engineers manage or are willing to combine both use cases in on driver. As they managed for the RX 570/580 with the 'compute mode'.


Do the blockchain driver not work with non reference cards? As the OEMs are just building different cooling designs on the cards?

GPU shortage just means they go straight to a big miner and no one else gets any....Must of been one gigantic farm.  I would love to visit that in 2022 in the great bitcoin crash that almost consumes the earth itself.

but really how can gpu shortage double up hash rate. If there are no gpu's available how do you increase hash?

Any thoughts??

The blockchain driver does work with the newer OEM Vega cards but apparently those cards are using memory (hynix) that may have lower tolerances and cannot be overclocked easily. The reference cards use the samsung memory that seems to tolerate higher or more aggressive memory overclocks. Performance is better on the reference cards.

So all things considered it is likely that there will not be a driver that prioritizes random memory access read/writes for newer AMD cards (Navi) since it seems that they are not willing to make that change for Vega now in the mainline driver. Which is sad because the performance of the new GDDR6 memory would certainly be helpful for cryptonight.

Its also funny to think that we are only using these cards for their memory performance only so its a pretty expensive memory stick.


Thanks for the feedback!
