Claymore's Dual Ethereum AMD+NVIDIA GPU Miner v15.0 (Windows/Linux)

[PPB]

I need to know Windows version, GPU model and drivers version to be able to reproduce this issue.

My specs:

Windows 10 x64 Enterprise - BUILD 10240
Driver - AMD blockchain Beta driver driver, 23 aug (windows driver version 22.19.659.0)
GPUs:
1x ASUS DUAL 480 4GB
1x Sapphire 470 Nitro+ 4GB
3x MSI 750 Armor OC 4GB

They all exhibit the changing clock/voltage -> lower performance until reboot issue that IMO is ADL related (as it happened always for me with Polaris GPUs, not only with mining, general use and gaming too, you can even see how the bandwidth is cut with AIDA or other bw gpu bench when you alter settings at least on windows with polaris GPUs).

The x25mv x50mv x75mv x00mv only voltage issue is a deduction of mine after seeing the gpu instant hang when using other voltages than these ones on the ASUS DUAL 480 4GB.

I'm selling my Gtx 1060s because they are not very good at mining. Whether it was the Hynix memory, or the bad components used, I only got  17Mh/s out of each card after OCing without touching the voltage. I cut my fingers twice with the fan blades, and whenever the network difficulty changes some of the cards hashrates drops to 1Mhs. I'm getting 22 Mhs from 570 8Gb and want to know how to increase hashrate other than increasing the memory clock, thanks.

Just get out now while you still can. Those GPU's going to start taking toes.

So my rig is currently going theough a ohase of restarting every day even though i havent changed any settings. But claymore hangs on startup unless I reduce the OC substantially. I have tried adding "-lidag 3" to the bat file but it doesnt change anything.

Anyone else had a similar problem?

Not able to Play with core voltage yet.

Using MSI AMD Rx580, Latest drivers for AMD , AB 4.4.0 Beta 16

Please guide me how to go ahead and resolve it for undervolt earlier version was at 90W per GPU only power now it jumped to 130-140W

Thanks in advance

I have random hang problem with v10.0, win 10, block chain driver.
I give up now and changed to sgminer with lower hashrate, no devfee and no more random hang problem now.

Stop takin a P00P at him

To the OP : Look up Bios modding, your 580 8GB should be able to get 29mh easy peasy at low overclocks.

You can reduce the clock, that should make it more stable.

His "570 8GB" should hit 29.5 with alt ethash coins or 29 if he is using windows 10+ Claymore 10 + Blockchain drivers. Also dual mining LBR he should get about 65 mh's with LBR or about 730 with DCR
All he has to do is A. Up the memory clock B. Run Polaris 1.64 and click the Memory Timing button to load the specific memory timing for the card. Nice new feature of the Polaris fork" and he is good to go, Also I would put the following in the Start.bat for his 570   -cclock 1175 -mclock 2050 -cvddc 900 mvddc 900 -dcri 20 (with LBR)   -dcri 25 (with Decred)

Further to this ive added "-gser 2" which has had no effect at all either. What is the setting for "-eres" is it better to set it higher or lower than default 2?

At my wits end now, just hangs and restarts the whole pc

What are you using to OC?  Try resetting MSI after burner to defaults if you are using it and dial back your voltage settings in Claymore.

I tried to reproduce the issue with clocks and low speed until miner restart.
Windows 10, latest blockchain drivers, stock RX580 Nitro+.
1. No overclock: If I start miner in ETH-only mode, it shows about 16MH/s only (and low memory controller load in GPU-Z) and I see this speed for about 20 seconds, then it shows 24.6MH and works fine. For dual mode it shows full speed immediately. Unfortunately, I have no idea why GPU works slowly within first 20 seconds, it is something related to drivers.
2. I close the miner and apply some changes in clocks: memory 2000 -> 2100, core 1300 -> 1100. When I start miner, I see that it applies new clocks in about 10 seconds, but still shows 18MH/s only for first 20 seconds. Then it shows about 25.5MH.
Note that I use default ROM so these speeds are not high.
3. I close miner and apply new clocks again: -cclock 1000, -mclock 2050. Same behavior: it shows low speed at start, then normal speed for these clocks. GPU-Z shows changes in clocks in about 10 seconds after start.

So right now I cannot reproduce the issue with new clocks: in my tests new clocks are applied immediately, I don't need to restart the miner or reboot the system.

Claymore,
I did not check ETH only mode, but in ETH+DCR mode it is easy to reproduce:
1) start mining (no clocks settings in bat file in my case)
2) wait until miner looses connection to pool (you can force it by unpluggung lan cable)
3) wait until miner connects to the pool again (plug in the lan cable)
4) in most cases the graphic card will work in P0/P1/P2 state with low clocks until you restart the miner

I have copyed parts of the log to this post, maybe it will help?

Then you should be able to see this issue if you press "0" key to disable GPU0 and then press it again two times to enable it. When I do it, everything works fine, I see P0 clocks when GPU is disabled and P7 clocks when it is enabled.

Mister Claymore.
Question about Vega eth hashrate.

We already achieved impressive 2000h/s Monero speed using HBCC with blockchain drivers and 2 high intensity threads with xmr-stak-amd.
PM me for details.

Is it possible that with complete miner rewrite, maybe with 2 DAG files in one GPU we can get significant boost with ETH speed?
Or maybe this miner already exists and is used with some private farms?

[kkourmousis]

@Claymore,

Just a friendly hint:

Sometimes miner can't reach maximum speed. I open the miner, clocks and voltages are being set properly but hashrate lies in the 225mh/s area. A simple miner restart resolves the issue

HWiNFO reports the desired clocks and voltages as set. The only thing that is wrong is the hashrate.


At first I thought that both the low hashrate on startup and random freezes issues were present only in multi-gpu rigs.

The low hashrate on startup occurred in my PC a couple of hours ago and it has only 1 gpu, so that is not the case. But what is interesting is that in my rig with 8 gpus it happens almost always, while in my pc with 1 gpu it happens rarely.

If you think it will help I can give you access to my rig to try to figure something out

Hello all

I cannot use key during mining
The letter is displayed in the console and nothing else happens.

I use Windows 10 pro

What I do wrong ?

Thanx

1. Do you see improvements for enabled HBCC in multi-GPU system? If you use single GPU it may help a bit in some cases, but I doubt that it will help if you have six GPUs. Also for XMR, may be you see boost because you use bandwidth of main RAM? Try to start CPU miner to check it.
2. I'm not aware of any faster private ETH miners.

I have no experience with 6 Vega rigs but it certainly works for 3 gpu-s.

Have you tried to start XMR CPU miner in parallel? Perhaps HBCC just uses bandwidth of main system memory. Just a guess, I did not check it yet. Though CPU miner mainly uses L3 CPU cache, not main memory, but soon I will check it anyway.
I have finished asm XMR kernels for all GPUs except Vega, I will check Vega in a day.

My system has poor Celeron G3900 cpu and cheapest ddr4 memory running low.
It cannot be boost from system memory.
I guess when you enable HBCC you are enabling some alternative paging scheme allowing effective usage of all GPU memory.
