Hi,

I used to mine with an other soft but my rig crashes last week due to windows update.
I re-installed windows and I am now trying to mine with cast XMR.

I am following this tutorial :http://vega.miningguides.com/
I have installed blockchain drivers (after using DDU), set virtual memory to 60000 but I want to test Cast XMR before changing bios etc...

When I start it, the miner seems to find everything (network, gpu) but it indicates 64 compute units and then artefacts appear...
I have 5 VEGA56 so I don't understand why it indicates 64 instead 56 compute units and I think artefacts come from here... (I have not modified anything else)

thanks for your help !

edit : I have desactivated crossfire in Vega driver and it seems to work... but still 64 compute units.

DDU drivers in safemode, reinstall blockchain drivers, make sure crossfire is disabled, might have to use regedit, disable windows update permanently.

I have been using CASTxmr for a few weeks and really like it's simplicity and function so thank you, Gandalph!

Had a question...I built 2 rigs:

Rig 1 - 2xRX570 4G and 1xRX580 8G hashing at 2468 h/s avg.
Rig 2 - 2xVega64, 1xVEGA56, 2xRX580 8G hashing at 7680 h/s avg.

I am mining both rigs for ETN at etn.spacepools.org using different workerid's but to the same wallet and have Cast 085, --fastjobswitch activated, AMD Blockchain driver, softPPlay, and OdriveN settings to get those rates on the Vega's and various bios mods for the 570/580 cards from around the web.

I was thinking that Rig2 with the higher total hash rate would find more shares than Rig1, but after starting both rigs at the same time, the shares found for each are about the same with a few more shares actually coming from the rig with the lower hashrate. Probably need to look into the concept of pool mining to figure it out, but was wondering if someone can provide some insight. I was thinking 3x more hashes would at least result in more total shares from one rig vs. the other.

Thanks again.

Check the difficulty on eac miner. I would expect the higher hashing rig to be on a harder difficulty.
Pools shift higher hashing miners onto higher difficulty to reduce their loading. You should get paid the same per hash regardless of difficulty.

Sure enough, difficulty was much higher on the higher hash rig. Slowly starting to make sense - shares subbed at higher difficulty are weighted differently than those subbed at lower difficulty for payout purposes, but in the end, it balances out. Thanks for helping to educate a newb.

Guys can you explain me this ?

GPU 0-3-4 ABSOLUTLY SAME CARDS 56s... GPU 1-2 Same 64s too...

Same clocks.... same cooling... same settings...

But different in temperature by 10c Huh

?

How is something like this possible ?

Yes,
I would bet you have 2 cards that have the filled package (Better) and three that don't have the filled packaging (shit).

https://community.amd.com/thread/219528

Have you looked at the HBM temperatures that the critical thing?
Take the higher ones off and redo the paste, may need a good amount of paste for the non filled HBM cards.

Hello,
did someone succeeded to enable the log function?
I am using cast XMR 0.8.5, I put "--log log.txt" in the command line, but it never makes a log text file...

i have the same problem can not set it up, which is really wierd

It works for me.
It creates the log file in the current directory, so if you run cast_xmr-vega.exe by some script/shortcut that have set working directory different from the cast_xmr-vega folder, then it will be created there. try to specify full log path.

For anyone interested to create a log file with current date/time in filename, here is the script to do this:

Code:

for /F "usebackq tokens=1,2 delims==" %%i in (`wmic os get LocalDateTime /VALUE 2^>NUL`) do if '.%%i.'=='.LocalDateTime.' set ldt=%%j
set ldt=%ldt:~0,8%_%ldt:~8,6%

cast_xmr-vega --log log%ldt%.txt ...

so the log file will have the name like this: log20180222_092247.txt

Hi all,

I've created a monitoring script for CAST XMR VEGA. Please review the post here:

Still have one of my Vegas mining at a good 100h/s slower than the other 5... and no idea why. They are all 56's flashed to 64's, running at 1950h/s except that odd one doing 1850. Same temperature, same clocks, same everything. Is there a logical explanation? Any suggestions?

maybe other memory type on that gpu

Fair observation... They're all the same on the outside (standard AMD RX Vega 56's), flashed with the same bios... so I would assume they all use the same memory... Will still check tonight, however.

Are you running video off that card? or onboard graphics?
Assume your temperatures are fine?

Could always be silicon lottery.

Nope, no video... and temps are pretty much the same across all cards... But the silicon lottery explanation feels kinda meh as the other 5 cards are literally within a few h/s... but that one is a hundred off. F@ck knows...

Interesting. I was thinking heat/worse thermal grease on the one card, but if you are seeing even temps, that would rule that out.

Funny thing is I actually have 1 out of my 8 Vega 56s hash less than the rest also. It wouldn't happen to be a MSI would it? Only way I can get them all to work properly is to run them in XMR stak using 1932/1932 threads instead of the regular 2016/1732. Kind of peculiar.

Nope, all Sapphires, all using the same bios, all clocked exactly the same. Funny isn't it?... One thing I would check (if these were Polaris cards) is whether that card is throwing memory errors. Unfortunately there's no way to check this on Vegas that I know of...

You're not alone, I have one like that to but I just cranked up the mem speed to equalize it.

at least for polaris gpus, there are bioses that have samsung/hynix timings inside. so if your vega has different memory type and even if you flash the same bios, just the onboard memory type gets flaashed
