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

[AlexanderDumas]

Hi!

I have a Ryzen 1700+Vega 56 on a MSI x370 Carbon Pro Gaming, recently reformated with Windows 10 version 1809, latest mother drivers + Radeon 18.6.1

I have a strange problem. If I start Windows and run Cast right away I get 1750H/s. If I leave it alone for a couple of minutes (?) and then I start Cast again, I get ~1100H/s. I have to restart Windows or suspend/resume Windows to get 1750H/s again.

Is there a way to fix this? Or maybe restart the driver without the need of restarting Windows or suspending/resuming? It's not a Cast problem because I get the same problem with other GPU miners (but not with CPU miners).

I do not want to sound like an axxole, but the causes could be many, and at this point in time with the mining gig so depressed, I doubt you will find anybody with the energy and time to spare and tell you more than what I am going to tell you now:
It is apparent that you use your PC for gaming and that is fine, I would stick to that and not worry about 200 hashes. Also because with one card only, you are scrapping pennies per day.
We all went through a lot of troubleshooting which most of it is documented on this thread and you may have to dig it out.
Most of us who run a stable and well performing rig, have a system dedicated with settings suitable only to mining.

I give you 2 tips: check if the gpu temperature stays below 70 celsius, because when it goes above 70c sometimes it throttle down or the driver reset itself to specs overclocking on order to protect the card. In that case you need to improve ventilation or GPU fan speed.
Then check on your MB BIOS if the GPU setting is on GEN1 or GEN2, which are the best settings for mining. Normally by default the MB are delivered on AUTO. Having  MB GPU settings on AUTO normally make the miner decrease HS rate or simply crash.

Then here is the best thing to read on mining with a VEGA.

Good luck!

No, I use it for mining and a bit of web browsing. And I'm not going down by 200 hashes, but 550. And Every penny here is worth mining because devaluation here has took a big hit on us and even with current "mining gig so depressed" it's still profitable here.

We all went through a lot of troubleshooting which most of it is documented on this thread and you may have to dig it out.
Most of us who run a stable and well performing rig, have a system dedicated with settings suitable only to mining.

I had it. But then I had to reformat and install Windows+drivers+miners again and the problems arose.
It's not that the card can't mine. If I start the computer and put it to mine right away, it gets a almost constant 1750H/s. But if I wait for a couple of minutes or I stop the miner and run it again later, it drops to an almost constant 1100H/s
I've tried looking not only in this thread, but on many other forums. And because this is a problem with any AMD miner, I've asked in other forums.

I give you 2 tips: check if the gpu temperature stays below 70 celsius, because when it goes above 70c sometimes it throttle down or the driver reset itself to specs overclocking on order to protect the card. In that case you need to improve ventilation or GPU fan speed.

I've configured to be t 68c and it stays there...

Then check on your MB BIOS if the GPU setting is on GEN1 or GEN2, which are the best settings for mining. Normally by default the MB are delivered on AUTO. Having  MB GPU settings on AUTO normally make the miner decrease HS rate or simply crash.

I'll look at it. One of the things I've done prior formatting is to update BIOS. Maybe that setting has changed.
But remember: miners go OK for DAYS if I start it right away or don't leave it alone. Also restarting or suspending/resuming cure the illnes.

Then here is the best thing to read on mining with a VEGA.

Many thanks! I'll check there too!!

I'll need it...

Hello,

Am noticing an issue after upgrading to Cast XMR 1.6+....after running for several minutes (sometimes as long as an hour) the hashrate on my rigs (4xRX Vega 56) will drop by 30%.  In tandem with this drop, the miner will report at least one "network error."  Other AMD rigs I have running the same version of Cast XMR (but 10xRX 580's) are unaffected as are any NVIDIA rigs.  I have played for a long time with the overclocking settings on the RX Vega 56's, and nothing seems to help with this issue.  When the rigs with the RX Vega 56's "hiccup" the network error they drop from roughly 1500 H/s to 1200 H/s.  Have also tried the Adrenaline 18.5.1, 18.11.1, and 18.12.1 with the same results. 

Conclusion I am coming to at this point is that there is a bug in version 1.66 which causes the RX Vega 56's to "downshift" if there is a network error...is anyone else seeing the same behavior?

[FoxByte]

As a follow up to this post, I am mining Haven.  Some additional observations -

I am seeing this same behavior with all my RX Vega 56 cards, doesn't matter what vendor or in what machine they are installed.  Interestingly, in one machine I have both Vega 56's and RX 580's installed.  When the "issue" occurs, only the Vega 56's hashrate drops....RX 580's are unaffected.

AscendingNight - Please add the new Hardfork from CryptoNight

Tax-Project uses the CryptoNight (AscendingNight) hash algorithm, which is optimized for CPU-based mining and GPU resistance, with the Algo specializing in fair sharing of the hashrate.
Tax forked from CN-Heavy to to their own custom variant recently and was hoping you could add support for it.

AscendingNight is similar to CryptoNight (same scratchpad implode and explode) but it utilizes a different main algorithm. While CryptoNight uses one aes step every second step, AscendingNight uses one AES every fourth step, has some substitutional parts and things like that to perform less calculations for more memory intesety.
In our private testing we came across performance boosts of 10% to 30% on Ryzen CPUs and up to 100% on older i7s.
Since the memory utilisation is still the same, the algorithm is just as fast on GPU (mathematically speaking, not tested yet).

The thing with Heavy, light and fast is just that, similar to CryptoNight, you can apply all the causal variations like CN-Heavy on AN as well (since it's just changing memory and iteration variables).

The point with the reference implementation of AscendingNight is that, while it's modular, it's still using 2MB as a scratchpad size and 2^14 iterations to increase the speeds of the validation process.
By increasing the iteration number to the casual CryptoNight step count of 2^20 you'd see an even higher boost in the performance of CPUs compared to GPUs.

The important changes were done in the post_aes macro. It can be found in here:

@glph3k
Thanks for your great $oftware!
Can you please please update your guide "How to mine CryptoNight based crypto currencies with Radeon RX Vega 56/64 GPUs"? The values showed there are for an older build and for v7.

Looking for suggestions on best settings, PPTable, for Sapphire Pulse RX570 ITX 4GB, single fan cards. 

These cards are tiny, draw little power, and before the last fork, with strap pimping they would get 900+ H/s, no sweat.  For CNv8, I've tried Polaris Bios modes, SRBPolaris, and I've tried generating custom PP tables.  I have one card that hits 830-870 H/s, the rest tend to stay at 650-720 on CNv8.  I've tried various ONT settings with P7 adjusted from 1150-1286/900-925; P4 adjusted from 1850-2100/900.

I'm using Cast 1.6.6 which I have used for a long while.  Cast is working just great with my Vega 54 flashed -> 64 cards.

Any ideas?  Anything obvious that I am overlooking?

RX570 ITX 4GB -- any ideas?

Dear glph3k,

Please check the hospital coin, it will fork CN-HOSP (Variant 4) soon.

1.7 came up!!

ast XMR Version 1.7.0 (2019/01/24)
support for CryptoNightV8-Fast (--algo=6) for mining Stellite (XTL). The previous CryptoNightXTL algo has been removed
support for Masari (MSR) upcoming network upgrade, Masari is also switching to CryptoNightV8-Fast, so change algo to --algo=6 when the Masari network upgrade is happening (scheduled for January 26th)
support for CryptoNight-Turtle (--algo=9) for the upcoming Turtlecoin (TRTL) PoW network upgrade (at block 1,200,000)
Vega FE: option to turn --intensity up to 13 for “Fast” CryptoNight variants to gain 2% higher hash rates

Hi!

I have a Ryzen 1700+Vega 56 on a MSI x370 Carbon Pro Gaming, recently reformated with Windows 10 version 1809, latest mother drivers + Radeon 18.6.1

I have a strange problem. If I start Windows and run Cast right away I get 1750H/s. If I leave it alone for a couple of minutes (?) and then I start Cast again, I get ~1100H/s. I have to restart Windows or suspend/resume Windows to get 1750H/s again.

Is there a way to fix this? Or maybe restart the driver without the need of restarting Windows or suspending/resuming? It's not a Cast problem because I get the same problem with other GPU miners (but not with CPU miners).

I faced the same, it's due to high graphics setting used for other running programs. So an easy solution for it, just set the intensity in miner lower... like if it is running on 10/10, So you change for -intensity=6/10 or 7/10, then you'll no need to restart your pc, hope so you'll cope upon this issue. Good luck.

And can someone tell me, Core i7, 8gb ram, and two vega 64 FE are installed in the same board with the drivers of Vega FE version 18.Q4. The speed for cryptonight heavy is only 1580~1600H/s per card, and 3900 for CN lite per card... and specially 4.5 M/s for Purk coin. How can I improve it for CN heavy???

[alankurt]

Is it advisable to mine with vega 64? I am mining monero and earn a misery

[GordoLui]

I have updated to the latest version of cast. My CNV8 hash rates continue to be around 1700 hs for a vega 56. Not sure why its low with me on here but it doesn't matter much anymore since the difficulty for monero just shot up so much this past 2 weeks i stopped mining it. But whattomine is saying that masari is the most profitable coin to mine with my vegas and that's what i will have them pointed at. So far im averaging around 3100 hs per card using the same settings on the cards that i use for monero. System total for 3 vegas is around 9200-9300 hs at 600 watts at the wall. At that rate im making a small profit with my farm.

[TradeGoob]

when trying to set fan speed and other low level functions I get this

setting card3 fan speed to 180
bash: /sys/class/drm/card3/device/hwmon/hwmon3/pwm1: No such file or directory

It works for only the first GPU. I get the above for the remaining GPUs.
What do I need to do?
I use Ubunto 18.0.4 Thanks

[TradeGoob]

Great work to the Cast XMR dev crew, but we are very disappointed that you do not provide support for Linux, specifically Ubuntu OS. This is the leading operating system used by pro miners and by anyone who wants reliable, stable mining, with proper security, monitoring, and non-pirate software. We would love to include this miner in our included profiles for PiMP OS / miner.farm.

Thanks again in advance for considering making it easy for PiMP OS to support this miner!

Hi,

be disappointed no more and check here:

How do you adjust fan speed for multiple GPUs? I keep getting errors when trying to set fan speed, men, and voltage. It all works for the first GPU, but not the others. Thanks for and guidance.

This is what I get:
setting card3 fan speed to 180
bash: /sys/class/drm/card3/device/hwmon/hwmon3/pwm1: No such file or directory

Ubunto 18.0.4 with three Vega Festivals

Dear Gandalph,

Please check the Hospital coin algo. This is CN-HOSP. I would like to mine with cast-xmr.
