Topic: [Cast XMR] high speed XMR/CryptoNight miner for RX Vega GPUs (2 KHash/s) - page 124. (Read 206406 times)

Windows Defender found this:

Trojan:Win32/Tilken.B!cl

mmmm, I've applied -20% power but min fan doesn't apply at all....

what's the reason to write --opencl 2??

my bat file is like that and I'm mining 1920 H/s

cast_xmr-vega -G 1 -S cryptonight.eu.nicehash.com:3355 -u "mywallet" %*

Hello everyone,

Another happy miner here running this awesome program and achieving around 1920 hashes, even without flashing or doing more tweaks. Will do more tomorrow

Nevertheless, I don't understand two things:

1. Nicehash stats are showing 1.67 kH/s, but the miner shows stable 1917,5. What's the problem here?

2. I've tried to configure manual fan's speed with 3000 rpm minimum and 3200 maximum, but wattman doesn't apply these settings, and it jumps to 4000 rpm or more without accepting my manual config. Is it normal? Temps were below 51 degrees....

Thanks in advance

V 0.6 has good as it gets for awhile?

I've been looking for some way to just scrape the output window but am coming up empty.  Really sucks that the two best CryptoNight miners around right now are lacking in monitoring support (Cast has no API at all and XMR-Stak has an API but it's not supported by Awesome Miner and doesn't do fan speeds and temperatures).  Come on guys, step it up.

Yay, 1920 H/s mining to nicehash!
Windows 10, Stock Vega 56, 950MHz HBM, -3% power, temp target 70C, min fan 2200

I definitely need to try this miner out on my AMD cards!

Ofc this uses multiple threads There is no way to get 2kh/s out of vega by single thread.

Interface simply shows only the total hashrate.

Or you probl knew this alrd, but then again, its optimized only for vega, since OP previously only had vega cards.

I would just like to thank you for this marvelous program!! Keep up the good work!  ;)

Okay, one thing i find interesting, is the lack of multiple threads. Unlike sgminer, you can't request the miner to run 2 threads on a single GPU. On sgminer and on Windows, this actually brought extra h/s.

CAST XMR's selling point is optimization for AMD Vegas. There is support for 5xx and 4xx in CAST but other older hashing scripts are probably better for the older AMD cards.

SGMiner  not run on my vega
i dont know
pls help me which version i use
thanks

Anyone here tried to compare it with SGMiner that comes with nicehash legacy?

On my rig 5x rx480 and 4x rx580 I am gettings 6.8Kh/s on Sgminer and 6.5Kh/s on Cast XMR so I am not seeing any improvement over SGMiner.

@Melandroscz, thanks for the tip, I'll try your settings, as I want to under volt my setup, and you seem to run them quite low.
By the way, what's your power consumtion?

Thanks again,
Pericle.

@xeridea, You saved my day, thanks!
The crossfire = off setting did the trick. Now all 6 GPUs are running stable at around 1900 h/s.
I'll watch them for the next hours, to see if they pass the test of time also.
And then tweak the voltage a little bit, as it consumes close to 200w/gpu now.

Thanks again,
Pericle

Thanks. I ll look into.

Well ppl complain about 800h/s per card and I thought 1kh/s per polaris is very good. So your pulling insane numbers, maybe downclock a bit?

Raijintech Morpheus II aftermarket air cooler - works with Vega's, though not designed for them.

Advantages are: good temps and damn near silent and it may end up with you applying better thermal grease, which should help whether you run Cast or something else.

Cons:  sets you back $60, somewhat delicate operation, exposes back side of the Vega

Disclosure:  temps no better than setting stock blower fan to 3,000/3,500 rpm -- but the Raijintech Morpheus II + 120mm fans is silent by comparison.

Start here for an overview:  https://youtu.be/THaMlkNDzYs

The YouTube video leaves out a few steps.  Here is what I would add:

1.  Use a very well padded counter top in case you slip, or the Vega slips, while taking it apart (towels, something very soft for the delicate circuitry when the backplate comes off)
2.  Use a new, good quality #0 philips screw driver -- you'll need it to remove the tiny screws on the top, bottom, and shiny display port sides of the Vega case.  Focus on the first quarter turn.
3.  Start by securing the 4 metal risers with plastic O rings to the Morpheus II plate and use some Loc-tite on this.  Leave it alone to dry while you disassemble the Vega.
4.  Remove tiny top screws, then tiny bottom screws, shiny plate screws, and then easiest of all -- the screws on the actual back plate.  Keep everything together in case you have to RMA or later resell.
5.  Use a new straight edge razor to carefully remove the white sticker on the X GPU bracket.  You need this sticker in one piece if you ever seek to RMA in the States.
6.  Careful when cracking the Vega board away from the metal frame (after all screws have come out).  You need to do this gently in order to access and separate the fan cable, and the cable that leads to the LED lights.  Crack it only about half an inch and separate those two cables.
7.  I use Q-tips + Acetone + 90% rubbing alcohol to clean the old crud off the GPU/hbcc die.  There may be bits of thermal padding on the mosfets and chokes, and I clean that off as well.  I place all the thermal pads onto the black metal frame in their appropriate indentations.  I use magnification for this step.  I spray canned air over the board when done to remove moisture and any residual crud.
8.  Artic 5 Silver seems to work well.  I apply to the Vega GPU/hbcc die and very lightly to the Morpheus II plate.
9.  Take your time applying all those narrow heatsinks to the Mosfets.  Note that even the low profile heat sinks will *not* fit the chokes that are located at the top of the GPU; the video kind of glides over this without explaining.  You can put heat sinks on the side chokes.
10.  Use books or something else to level up the bare, stripped down Vega board with the Morpheus II plate when lining up the new GPU brace and screwing that in.  Otherwise, with all that thermal grease, the card will slide all over while you are trying to screw in the new GPU metal brace.
11.  You could probably get by with (1) 120mm fan clipped to the fins over the GPU, but I would use (2) 120mm fans.  Order some 1 to 3 fan cable splitters ahead of time.
12.  Go into your bios and dial up your motherboard fan settings.

Carry the Vega + Raijintech cooler using the shiny display port front part and the back edge of the card, avoid touching the exposed back of the Vega.

Also, I found it easier to clip the (2) 120mm fans onto the Raijintech Morpheus fins *before* securing the Vega to the Morpheus II.  Fan clips take a little while to get used to.

Artifacts is a sign of memory instability.  I run 930Mhz and 950Mv.  Try bumping up your mem voltage. Most cards I can run up to 950Mhz, some require me going to 910 or 920. Also, high core clock is not needed.  Could also be power supply unstable at higher power draw, what PSU(s) you have? Have you tried only cards 3,4,5? Or last card by itself? It could possibly also be a riser issue.

---IMPORTANT--- One thing to for sure always check, extremely critical.  Make sure crossfire is off.  It can be reactivated when adding cards...... Crazy severe artifacts right when miner starts is sure sign CF is enabled.  If GPU Tach lights on the card is green, sure sign CF is enabled, but sometimes it is red like normal even with CF on. Lesser artifacts point to mem instability.  HBM2 is temp sensitive, check GPU-Z, keep HBM2 under 70C, lower is better.

I have 6 rx 580 and I have come to work in 7700hs but very unstable, memory failure, neither virtual memory nor with regedit. Very unstable, but I manage to solve blocks. Any ideas to stabilize memory error? thanks to all
I leave you a link that I could record before they freeze. help plis
