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

[TheRealSelector]

My single STOCK Vega 56 gets 1940-1950 consistantly long-term, I've not bothered playing with the BIOS as I'm not sure how long it's going to be pointed at Monero mining and it doesn't NEED a modded BIOS for it's later "long-term" home.

more or less the same here. I cannot bother changing the BIOS, after talking about it, so I use OverdriveNTool with the settings I shared before, and it is incredibly stable now, both the program and the cards can be the entire day working at full speed, except if I get an internet connection error. Average hashrate of 6 Vega 56 is 11500H/s approx.

I really wanted to use this miner but it has a flaw… I’ve been using it for the past 3 weeks and I’ve been getting 10% submission errors… For now the XMR Stak is more stable for me with only 0.02% submission errors…

I’ve even tried using the —fastswitch feature but that lowers my hash rate by almost 200H\s per card… Plus, this one is 2% dev donation as opposed to Stak which is 1% and more stable…

which settings do you use? What's the speed of your Vega (56 or 64?) cards?

From personal experience, this program is slightly faster, and also more sensitive to changes or it pushes the Vegas a little more. If you have Vega 56 cards try to set them at 935MHz or slightly below, mining speed should be around 1920-1950 H/s, which is pretty good and they are 100% stable.

I've shown the settings I use before and I am getting 0 errors every 2 hours. This is a screenshot after exactly 1 hour (59 minutes 20 seconds) of mining:

I have 3 Vegas 64 on that specific rig, all have 1100Mhz power table.

GPU section:

State 6: 1212Mhz - 900mV
State 7: 1407Mhz - 905mV

Memory Section:

State 3: 1100Mhz - 900mV

nice numbers.. At which speed does XMR Kast mine?

I have no experience with the Vega 64, but for the looks of it, you might need to find the sweet spot for your Vega 64, MHz wise. Vega 56 sweet spot is around 930-935MHz, again, from personal experience, this might differ.

At anything above 940MHz, if I set a Vega as the main GPU, everything seems normal in your OS' desktop, but then after doing something as simple as using GPU-Z to check stats, screen artefacts start to show everywhere on the screen, like when you overclocked a card too much.

Using Cast XMR alone seems fine, though, your OS' desktop won't show artefacts and the cards will be running, BUT I got random hangs so I used a 10 minutes timer to restart Cast XMR and OnedriveNTool, and you get more errors. It's been 2 days the 6 Vega 56 rig is running stable and the difference is night and day, you can sleep well.

Also overclocking can lead to de-configuration of your card's settings, as if the card forget their own settings which you had set up at startup, and can get over 80º with the fan spinning at something like 1000rpm and be happy with it --this means the card can wear off and not last much.

Stak miner at the same speeds but I just noticed something that I haven’t noticed before.

The submission errors I get on Cast are the same I get on Stak when I mine on NanoPool

When I mine on Spacepool I have far less submission errors… But with Spacepool I don’t get what I am suppose to get (12.5ETN coins per hour)… I get a payout of roughly 7.5ETN per hour….

I am having an issue with Vega 56 crashing when trying to tweak as per the tutorial here: http://www.gandalph3000.com/cast_xmr/cast-xmr-optimized-cryptonight-miner-for-rx-vega/

I have the Vega "Blockchain" drivers installed (fresh install). If I try to use any of the settings bellow as per the tutorial, I will hash for no more than 3 or 4 minutes, my screen goes all pixelated, and Windows 10 crashes forcing me to reboot.

If I leave Cast running with "default" Vega settings, I am hashing at 1600H/s and its stable, but I obviously want to increase it if possible.

Settings I have tried without success:

1900 Hash/s with 150 watts power consumption

    Core Frequency: -10%
    Memory Clock: 945 MHz
    Power Limit: -22%

2000 Hash/s with 200 watts power consumption

    Core Frequency: -10%
    Memory Clock: 965 MHz
    Power Limit: 0

2050 Hash/s with 225 watts power consumption

    Core Frequency: -10%
    Memory Clock: 990 MHz
    Power Limit: +12%


Anyone have any ideas on how to properly tweak the Vega settings as I dont really have any experience on overclocking or undervolting GPU's.

Tx  

Try adding on the command of cast-xmr.exe: -I 2 --fastjobswitch

What does the command do for the card exactly?

That command should lower a little the intensity of the mining process, I still get a stable 1910H/s with that command

Ok, so I have now installed the Vega 64 BIOS and I'm running:

    Core Frequency: -10%
    Memory Clock: 1105 MHz
    Power Limit: +20%

And only getting an average of 1982 H/s @ 280W power usage. Seems like low hash rate for the settings with high power usage. GPU is sitting around 68C with 3300 RPM on the fan.

Is it nessesary to do the power-play hack to the registry in order to touch the 2050 H/s realm?

[jyakulis]

ok interesting, i looked into this a little more.

I upped my frequency to -10 from -30. I will see if it's more stable. I was following the STAK reddit guide. Seems things evolved quite a bit.

I'm fooling with 0% tdp. It costs about 150 extra watts at the wall vs. -20% tdp on 3 Vega 56. It's does not really matter to me. I have big enough PSU, I just want stability. Profitability is about the same, all I want is good stability. I'm curious why the virtual memory settings matter...

I switched back to the Vega 56 BIOS as I see ZERO reason at this point to upgrade. Even though you can up the Memory Freq past the 56 BIOS (stable) limit of 935MHz, there seems to be no real gain in any way, and in fact, power usage seems to go up compared to stock 56 BIOS.

My current settings with 56 BIOS @ 1942.9 H/s Average @ 68C Temp:

GPU: Freq% = 0
Memory Freq% = 935 MHz
Power Limit: +10% (However this does not seem to make a difference weather its 0% or 10%)
FAN: 2000 RPM

THIS SEEMS TO BE IMPORTANT!!!!!!

Disabling and reinstalling the Vega 56 in "Device Manager" after any Wattman changes seems to add a level of hash-rate stability, though I might be imagining things.

8 days mining with nanopool 1 card vega 56
Balance  0.1358 XMR

good result ? or should i move on to dwarfpool  Huh  

4 more vegas on the way

if you aren't going to flash the BIOS -I can't for instance- and want better temperatures I'd wholeheartedly recommend you to read my post on the matter of Vega 56 settings and bat files and Windows restarts.

https://bitcointalk.org/index.php?topic=2256917.1200

If like me, you can't flash the BIOS -or maybe you prefer not to-, dont mind the comments saying that's unnecessary 'cos it makes a hell of a difference and your life easier and you can have a 24/7 rig without hash errors at all, low power consumption and a totally automated process at every restart -say your computer is powered off- without you touching a single setting!

This guide is excellent to start.

http://vega.miningguides.com/

btw pyr8, those temps are a bit in the unacceptable side. A number in the 50s or less is ideal.

@almost30 that pace seems ok. What's your simple Vega hashrate as of now? You'd get around .84 Monero with that speed in 8 days, and in less than 2 days the rest to get 1 Monero. 10 days = 1 Monero with 6 Vega sounds like a quite good hashrate to me.

What does it mean Avg Job Time ?
Because this number is too big in my output.

[09:39:14] Shares: 3624 Accepted, 2 Errors | Hash Rate Avg: 11781.7 H/s | Avg Search Time: 13.2 sec

Where I can send issues? To this topic? Miner app will sometimes freeze.

I see here that many people claim to get 1950 Hs with memory speed of 945 or so. I'm wondering what i'm doing wrong - i'm also getting 1950, but with memory at 1100 (and gpu at 1407). If i set memory to 945, hash rate goes down to ~1700-1750!?

I'm using Vega 56 cards, with 64 bios and registry files for HBM1100. And of course, blockchain drivers and latest version of Cast XMR.

P.S. i have 6 cards, tried with single one and same result. I'm also using only 2GB of RAM, not sure could that be an issue (but i doubt, as all calculations are done inside GPUs).

thanks

Hi guys,

I was wondering since your software supports Vega but also polaris, why not allow for older cards like Hawaii? (r9 390/X & r9 290/X)

I own this card and search for the best software to mine with .

Sad to see it doesn't support R9 390X. Great card though (modded bios to lower consumption).

Merry Christmas & Happy new year to all of you!

well, you modded the BIOS, that's the most likely cause. For instance, I can't mod it because the cards in the rig arent mine. But the 6 Vega 56 GPUs rig whose owner wanted me to build for him are set up to run at 935MHz, with OverdriveNTool -I dislike AMD Wattman, it's enough having it on my desktop computer every single day- managing the settings.

At 935MHz the unmodded Vega 56 mine at around 1940H/s with 100% stability (= 11600-11700H/s all of them combined), which in the end is what makes the biggest difference. @commonrnx shared a couple of very interesting videos on modded Vega 56 cards.

I have no experience with modded cards but the settings are ok for a modded Vega 56 GPU afaik -Vega 64 HBM can run at higher speeds, which is what a modded Vega 56 achieves-, 'cos they run at Vega 64 speeds, just with lower consumption. Maybe someone who has modded Vega 56 can help you more concretely.

Thanks, I've been running stable all morning at 935MHZ on my unmodded 56's.

I'm at target temperature of 60C
Fan minimum at 2500RPM
TDP 0

Fans are not roaring with these settings but hover around 3000 rpm

I like the big numbers at 0 TDP but there is only a $0.03 gain per day at my electricity cost for the extra hash.

Anyway, all that doesn't matter. 935MHZ seems to be the sweet spot for me with CAST XMR on unmodded 56's.

I save about 47 watts per GPU at the wall moving from 0 to -20% TDP. When I run lower I can set the fan minimum to 2000 RPM and target temp to 60C and fans hover around 2500RPM. That's better for me. I'm so over the ridiculous fan noise.

[sypher9]

anyone using RX Vega Frontier Edition with Cast XMR ? Is it supported? Hard to find VEGA's in Canada right now, looking to buy the FE instead.

One you upgrade to the 64 BIOS, you have to use 64 settings. 1950 H/s @ 935/945 is for 56 un-moded cards!

Try these settings (for your appropriate card and BIOS type) NOTE that it's a starting point, your results may vary slightly:

Vega 64 Hash Rates

1900 Hash/s with 200 watts power consumption

    Core Frequency: -10%
    Memory Clock: 1025 MHz
    Power Limit: -23%

2000 Hash/s with 250 watts power consumption

    Core Frequency: -10%
    Memory Clock: 1095 MHz
    Power Limit: 0

2050 Hash/s with 280 watts power consumption

    Core Frequency: -10%
    Memory Clock: 1105 MHz
    Power Limit: +20%

Vega 56 Hash Rates

Hm, sounds strange to me, as i though vega64 bios is used only because of better undervolting and overclocking possibilities. Instead in relative percentages, do you know exact frequencies of GPU at those settings? I'm most interested in lower power consumption (150W) and getting about 1900 Hash/s is just fine to me. Even if cards doesn't complaint about 1100mhz, i believe they will be more relaxed on 945MHz.

And just to be clear, you didn't even change registry for voltage adjusting, just using installed drivers/cards with factory settings?

Btw, is there any explanation of intensity argument, and how to find the best one for the card (except trying all 10)?

I've never understood the above - I'm able to get 2000H/s on my Vega 64 @ about 150 watts, no bios tweaks, no reg edits.

1100MHz memory clock.
-30% core clock.
-30% power limit.

The only reason I'm mining VTC instead of Monero is because the beta blockchain driver is dogshit and keeps having "hiccups" that drop the hashrate to 1700~ until the card is restarted.

I really wish the OP would allow the full speed on non-beta drivers, they're antiquated and unnecessary now.

How many will RX VEGA cards work in one system?
I was planning to buy 13-card based board or even 19-card like Asus Mining Expert but I don't know if it will accept them.

[QuintLeo]

Most folks that have posted about working with more than 4 Vega in one system have said it's a nightmare when it DOES work - and I have yet to see ANY posting of more than 6 actually working.

Hi guys.

I have a problem with my vegas.

I have a MSI z370 PC PRO motherboard and 2 vegas plugged in.
With only one vega connected i hace no problems at all. works fine.
But when am trying to connect the second, and start mining with the second i got a crash when i start cast xmr.
When i am using a only one vega AMD settings shows normal, if 2 vegas are connected, HBCC memory option in amd display settings just disapear.

1st vega is connected to PCI-E x16
2nd vega is connected to PCI-E x4

iI have more PCI-E slots, but they are mini PCI, and i need a riser in order to use them.
I have tryied to change in BIOS settings enable minngng, but am still having the same crash when 2nd vega start mining.
Do you think if I buy a riser and connect the second vega to a mini PCI, can solve the problem?.

rest of my specs are:
i5 8600K
SSD 250
16 gb ram
2x vegas 56

Thanks all!!
