Hi guys! Who ever faced such a problem?  z270p board here with vega 56 running HiveOS  https://imgur.com/a/Qjqx3a1  Please, help. I do not know what to do)

tdxminer version 0.2.2.2
This is a beta release and may be unstable on some hardware.
failed to build program.
[2018-07-09 06:54:00] Failed to initialize device number 0.

I have same problem with you.
Trying most of everything. Ubuntu 16.04.4 , Xubuntu , try many of low latency Kernel.
I had no problem with rx570,580

btw I am using Sapphire Nitro Vega 56 with Z270 TUF2 mobo.

If anyone would help with disk image / iso. That would be a lots of appreciate.

I tested bsod and got arount -30% reward. So i decided to change to another one, i tested angry pool, for some hours the reward was good, but in 24h reward was -40% that calc says.
Finally i tested https://www.pickaxe.pro and got arount +50% in the first 24h(maybe lucky), but average in 1 week is more than the calc says for me.
Today was a bad day because the pool hash rate wasn't good.

Ive been having the same problem. I looked into it a bit further and realized the issue isnt with the calc or lyra. The major pools for these coins dont use pplns or pps payout schemes. They use proportional payout. The culprit: pool hoppers. Just look at the angry pool and bsod stats for lyra. Huge hashrate spikes and then returns to base line. Each time was during low difficulty blocks. And since it take 100 fucking confirmations, they have plenty of time to hop in and bail with profits. Thats why pickaxe pool gave you an accurate payout. The hashrate remained consistent.

Fist of all i should thank the dev for making the vega very profitable again

Here is what i did

6x Vega 56 (MSI Airboost OC)
Asus B250 Mining Expert Mobo with PCI-E 1x risers and Gen3 in BIOS

1. Freshly Installed Ubuntu 16.04 Desktop (http://releases.ubuntu.com/16.04/)
2. Followed the ROCM AMD Driver Installation (https://github.com/RadeonOpenCompute/ROCm)

Created a Fan Control Script (amd-fan.sh)

#!/bin/bash
/opt/rocm/bin/rocm-smi -d 0 --setfan 150
/opt/rocm/bin/rocm-smi -d 1 --setfan 150
/opt/rocm/bin/rocm-smi -d 2 --setfan 150
/opt/rocm/bin/rocm-smi -d 3 --setfan 150
/opt/rocm/bin/rocm-smi -d 4 --setfan 150
/opt/rocm/bin/rocm-smi -d 5 --setfan 150
exit 0


No other Overclocking as it does not improve my hashrate but the Power consumption but with the stock settings and fan limit each card is consuming 150W so total 900W

At present getting 35Mhs and miner is very stable, actually impressed with it

Will play with OCs soon and update

I must say Vega is pretty stable on linux, i have been mining Haven, Loki on windows and i know how hard to keep watching the miner crash, thanks a lot Dev @todxx

You don't need to target every GPU in your script with -d parameter. If you type

/opt/rocm/bin/rocm-smi --setfan 150

it will set fan value on all GPUs.

[batagope]

Because tdxminer doesn't show info about temperature and fan speed, you can use utility of rocm drivers.

If you  open new terminal beside your tdxminer and type:

Code:

/opt/rocm/bin/rocm-smi

you will get info about temperature, average power consumption, fan speed, and other info about your GPUs.
Problem with this command is that it only shows current state of your GPUs. If you want to monitor GPUs info for a certain interval, you can use watch command. Type in your terminal:

Code:

watch -n 0,5 /opt/rocm/bin/rocm-smi

and you will get your GPUs info every 0.5 second.

I hope that this post will be helpful for some of you. Cheers.

Failed to initialize device number ...

There is a solution of this problem?

[Saphire]

Any news for windows version for tdxminer ?
Most of ppl are waiting for it.
I hope you can do it (or you done but dont share )

[GreyGhost_rc]

I get around 2.6 mh/s on my rx 470 cards, but only 1.1 mh/s on my gpu0. Any ideas?

[whhynothro]

I am very impressed with the hashrate this miner is getting on amd.  That being said... It's glitchy, it overheats gpus like crazy and its still in beta mode.  I must say that 3% dev fee is uncalled for.

[Comgold]

confirm, the problem is on lyra2z. On phi2 or any other algorithm 3-4% deviation with calculators but not 27%... And about the fact that the calculators specifically do it - it's not exactly, just the Lira was apparently not designed for such a power network, and now there is an error in the calculation of complexity.... Generally when podseti arrived at лиpe2з necessary from the final profit take 27% 

Problem in a pool. If it is impossible to set difficulty, there will be a fall of profit.

Minecore.pro there is an opportunity to regulate difficulty. On ravein everything is good, but on gin for some reason there are no payments. If who knows still pools where difficulty can regulate, tell about it please.

On the picture two 8x1080ti from the set difficulty, and 6x584 (20,5Mh) difficulty appointed by a pool.

and why not put 6x584 manual difficulty? and I do not quite understand what gives manual complexity and how it affects the profit 

[Comgold]

The more difficulty, the more has to be productivity in Mh to find the solution. If difficulty above the nominal productivity of your video cards, the longer they look for the decision. On the picture it is presented 6x584x24h from constant difficulty. Compare the schedule to the schedule on angrypool.

https://ibb.co/b89sCT

The schedule for constant difficulty for raiven. Too it is very indicative in comparison with other pools.

I'm making some progress with this miner

I had issues for a few days, still not sure what went wrong. I wasn't able to connect more than 1 GPU (RX Vega) and I was getting PCIe errors during boot. Finally, the boot process fails with more than one GPU.

I've reinstalled Ubuntu on another motherboard, the ROCm drivers, and it seems everything works just fine now.

I've even written a simple Python program to monitor GPU temps and increase or decrease fan speed. So far so good.

Now, I would also like to be able to undervolt the GPUs but I couldn't find a way to do it using the current ROCm driver.

This was a great advice. Thanks

My rig is working great.
4xVega46 @28.Mh/s on stock settings except the fan speed.

Unfortunetly stock setings becouse I cannot OC.
Tried to use rocm-smi. No luck.

Code:

 
GPU[2] 		: Supported GPU clock frequencies on GPU2
GPU[2] 		: 0: 852Mhz 
GPU[2] 		: 1: 991Mhz 
GPU[2] 		: 2: 1084Mhz 
GPU[2] 		: 3: 1138Mhz 
GPU[2] 		: 4: 1200Mhz 
GPU[2] 		: 5: 1401Mhz 
GPU[2] 		: 6: 1536Mhz *
GPU[2] 		: 7: 1711Mhz 

Code:

 /opt/rocm/bin/rocm-smi  --setsclk 7

But that does not change anything.
Since those cards will be water cooled I wondering how to OC?

The only way is to flash my Vegas with LC bios? Really?
Cheers.

I don't wont setsclk to 5. It is 1401Mhz GPU. I wont to set it to 7 @ 1711Mhz.
This was easy done in Windows. Cards worked great. Here I can't force power play to pass 220W. Setting --setoverdrive to 10 and more crashes the system and does not change anything.

And --setmclk 0-2 does not change the mem freq. It is on level 3 constantly.

Even changing --setprofile # # # # # does nothing.

Code:

GPU[1] 		: Minimum SCLK: 1600MHz
GPU[1] 		: Minimum MCLK: 945MHz
GPU[1] 		: Activity threshold: 0%
GPU[1] 		: Hysteresis Up: 0ms
GPU[1] 		: Hysteresis Down: 200ms

Did you attentively read the reference? And that you will burn the card and all.
Try it

--setoverdrive %            Set GPU OverDrive level (manual|high)

--setoverdrive #: This sets the percentage above maximum for the max Performance Level. For example, --setoverdrive 20 will increase the top sclk level by 20%. If the maximum sclk level is 1000MHz, then --setoverdrive 20 will increase the maximum sclk to 1200MHz

But personally I didn't try it.

May be --setoverdrive High

As a matter of fact I did read the reference thoroughly.

1. Setting --setoverdrive % is valid ONLY for the highest performance level which in case of Vega64 the 7'th. The 7'th performance level is @ 1711Mhz for the core. So increasing --setoverdrive % of 10% set (theoretically) the highest clock to 1882,1Mhz which is impossible to handle by the core at the stock voltage.

2. I don't know why Rocm set the 7'th clock level to 1711MHZ since the card have 7'th set to 1630Mhz under Windows.

3. Rocm can force Vega to work in 7'th clock level without the load( all diodes on the cards are on). Than it is 1630Mhz even though there is not such supported frequency.

First frequencies under load. Second idling.

4. There is no information about what kind of power is displayed in rocm-smi. If this is a hole card power we have a lot of room to growth. But if it is a Core power only. hmm.. I have never seen numbers above 211W. TDP VEGA 64 Air is 295W and LC 345W. Under Windows we can monitor at lest 4 different temperatur of the VEGA 64 (CPU thermal diode, HBM2 temp, Hot spot temp, vrm temp) and power for the core and for the GPU package. Rocm can provide only CPU thermal diode temp and some kind of udefined power consumption.

5. The most important temp in terms of Lyra2Z algo is the Hot spot temperature which we don't have under rocm. There is many speculations about what is a Hot spot temp in fact. I like to belive that it is actually a SoC temp. It has no direct contact with the heatsink so gets very hot. Especially during gaming or, as i presume, during Lyra2z mining. Using cryptonightv7 algo we can observe that the hotspot is up to 10*C higher than the core thermal diode since it is a memory intensive algo. But during gaming the difference can be up to 20*C and easy hit 100*C.

Conclusion:
Vega 64 on air can work up to 6'th freq level when mining (only 6 diodes on the cars in on) The limit is the power. At least the Vega 64 air bios not allowing to pass 220W.
Since the PowerPlay table can not overclock the 6'th or 5'th freq level to achieve higher hashing speed we have to undervolt the card to meet 220W limit. That should boost the core frequency by itself.
Since I don't know any way how to undervolt the the GPU we're back to square one.

At the end of the week I'am planning to install a water cooling on my 4 Vegas. I wonder how the frequency is scaling with the temperature. Than I will re-flash those cards using Vega LC bios.

I'll keep you posted.
Cheers:D

I generally try to receive the maximum productivity, at the smallest consumption of energy. What from us is gradually taken away by producers since it is necessary for them that the video card has failed through certain time what we would buy the new video card.

Indirectly it is confirmed by three monthly guarantee for the video cards mining edition.

Therefore with interest I will watch your experiments.

I wish you good luck.

[CharlieCox]

Our only hope at the moment is the new version of ROCm drivers, which should support newer kernels and offer more features (fingers crossed for undervolting).

Until then, I run my RX Vegas in level 4 and 2 

[Saphire]

Any idea what is the power consumption of AMD RX580 mining with tdxminer on lyra2z algo? More than Nvidia GTX 1080Ti or better?
I think they wont release the windows version?

[Saphire]

My electric cost is so much so i really care that one.
250W/ cards is really high for lyra2z algo.
My GTX 1080 Ti cards power consumption is 125W per card.

8x rx580 cc1210 mc1000 cv900 gives 27kh/s and takes 950W, you can probably go lower with power consumption.
