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

[Temporel]

Is anyone also has issues with forced Windows Update "NVIDIA - Display 23.21.13.8768"

It installs authomaticaly and breaks mining.
After that I need to manualy rollback to 385.41

disable autoupdate. If Windows 10, use gpedit.msc

Excellent programming work Claymore. Keep it up.

First post in this forum, just to say good job Claymore on the 10.0 version, it seems to take really well the clock and voltage options now if paired with AMD GPUs and the blockchain driver.

I would like to ask Claymore 2 questions:

- I have probably have run into a little issue in regards to core voltage settings with the miner. I have one GPU that when set to non-rounded voltage values (as the GPU only recognizes 6.25mv steps, this means all the voltage values that arent x25mv, x50mv, x75mv and x00mv) it misheaves pretty quickly and has OCL thread hang just a minute after starting mining (DAG is already loaded and no EDC errors are shown. If I use rounded values, it seems to take them better and if a OCL thread hang happens, it happens after several hours and probably blamed to memory clock instability.

- As you know, the clock and voltage control API from AMD has a mechanism built in that in the end reduces performance very time you touch any core/mem voltage/clock values if they were changed AFTER the GPU entered, even if for just a little moment, in maximum core and memory Pstate. I have seen when doing the OC/UV settings with your miner that the settings I put are enforced just before the DAG loads, but still with soft monitoring the GPUs enter for a brief period in max clock/voltages before that, causing that any clock/volt setting enforced by the miner, if it happens to change an existing value (this doesnt happen at all if the GPU had these values since last reboot), it enters in this "reduced performance mode" and thus hashrate is lower than you should. Is there any chance that the voltage/clock options are enforced first of all, so this behaviour doesnt happen? Because every time I have a OCL thead/hang, I have to do 2 reboots, the first one automatic from the miner and the second one to have the clock/volt dialed in a first time so the next reboot the GPUs dont enter in this "lower performance mode". i know i could just bios flash all the OC/UV/fan settings, but im still at finding the best OC/UV settings for each gpu, and I would like to nail them via driver changes rather than BIOS modding yet.

All in all very satisfied with this new version.

Thanks in advance!

I'm running v10 and the overclocking and voltage control are pretty great features, but they need some more work.
I have a very strange problem. Most of the time, when I power on the rig and start Claymore, the cards appear to be clocked to the correct frequencies set in the .bat file, but they mine with the hashrate of stock clocks. I have to stop Claymore and start it again for the cards to mine properly. For example, at stock speeds (1265/1750mhz) they mine with 24mh and at 1100/2050 they mine with 29mh. On the first run, gpu-z shows 1100/2050 clocks but the cards mine at 24mh. When I restart Claymore, the cards are at 1100/2050 again but they mine with 29mh. Also, sometimes the voltages don't change accordingly, so every time I have to check the voltages with gpu-z, to see if everything is correct and this kinda blows the idea of having a fast way to restart a miner and have him up and running in no time. I know other people that have the same problems. Hope that this gets fixed soon, since this automatic overclocking from Claymore is an extremely helpful and easy way to overclock.

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

Well you can have mine..

I am struggling on resolving both of the 2 listed problems below, I have found a solution for the second, I will post more info soon

So I have been using the latest Claymore version since it came out.

My rig:

ASUZ Prime Z270-P
8x RX 580 8GB Nitro+ (Hynix)
Windows 10
Blockchain Beta Official Drivers
Claymore Dual Miner v.10.0
Modded BIOS, OC through Claymore @162w from the wall per card
Dual mining ETH (233 Mh/s) +DCR (7000 Mh/s)

I am overall happy with the new update, but I have had some issues:

• 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
• Computer freezes. This has happened 2 times in my rig and 1 time in my PC (same setup with 1 gpu only) in the last 2 days. Here is the last part of the log @Claymore in case you find something interesting here
  

Btw, the problem that miner does not reach maximum speed on first run after restart is PERMANENT for me, it happens on almost every restart.

@kkourmousis,
power doesnot seem to be the issue. I have the same thing with my rig and tested it with 2 and 3 GPUs and it still freezzes

Caution: LONG post ahead...

Regarding the freezing rigs after connection loss or after a gpu hang:

First of all, some of you may want to take a look at my previous posts, I have been trying to keep everything summed up for people with similar issues to be able to check them out all at once.
So here is my initial post and here, here and here are the ones that followed on that issue. For those of you guys that just want to read my conclusion, you can skip those.

My "verdict" is that sometimes when the miner starts it causes a power consumption spike, which may be above your rig's max power. For me it happened almost always after a connection loss and sometimes after a gpu hang.

First of all, here is a graph of my power consumption during my tests:



Keep in mind that I have 2x 750watt gold PSUs, so 1500 watts is my limit. Now take a look on those spikes.... yeah...

I will spare you from too much of big data and focus on the incident I have my cursor on in the above image (04:32 2017-09-17)

Here is a log from that connection loss:

Since the above graph is too zoomed out, here you can see a zoomed in cut from that incident where you can see that after that spike, my rig froze:



The other spikes you see on the main graph on top are the same case (those 1800+watts made me skip a heart beat when I saw them).

So, in the end of the graph you see stability. This is the most continuous period I have managed to run my rig for with the blockchain drivers. The fun part is how I did it:
I changed:

Code:

-cvddc 875

into

Code:

-cvddc 850

........

Such a lame ending for such a big torture I have been through... I changed that in order to reduce my power consumption so my spikes would be withing my PSUs capabilities, and while I did that, no more spikes!

So that was it. I have been running stable since then, I sacrificed 10Mhz of my -cclock in order to keep up with the 25mV reduction on -cvddc so I lost a bit of speed, but at last I don't have to wake up every 2 hours or so to check on my baby-rig.....

Conclusion:
My "verdict" is that sometimes when the miner starts it causes a power consumption spike, which may be above your rig's max power. For me it happened almost always after a connection loss and sometimes after a gpu hang.
If you experience rig freezes with blockchain drivers and Claymore v.10.0, the miner could be causing spikes that are beyond your PSUs capabilities

P.S.1: In the graph you can see that in the middle of my "stable period" the power consumption got up a bit. This is because I initially dropped my -cvddc  to 840 before I decide to step it up to 850.

P.S.2: The freeze issue was happening on the following equipment:

My rig:

ASUZ Prime Z270-P
8x RX 580 8GB Nitro+ (Hynix)
Windows 10
Blockchain Beta Official Drivers
Claymore Dual Miner v.10.0
Modded BIOS, OC through Claymore @162w from the wall per card
Dual mining ETH (233 Mh/s) +DCR (7000 Mh/s)

and with the following miner parameters:
 -esm 0 -estale 0 -asm 1 -dcri 30 -cclock 1140 -cvddc 875 -mclock 2100 -mvddc 850 -tstop 80 -tt 70 -fanmin 15 -fanmax 85 -mode 0 (These are my parameters before I applied the solution I describe above. Also, -mclock 2100 was +/-30 for some of my gpus)

P.S.3. Sorry for the long post... Keep in mind that it was a hell of a lot longer for me  

[kkourmousis]

@kkourmousis,
power doesnot seem to be the issue. I have the same thing with my rig and tested it with 2 and 3 GPUs and it still freezzes

Sorry to hear that. Try what worked out for me: lower your -cvddc a bit

Check my above post for more info

[notbatman]

Whoever it was that posted about the ROCm kernel many pages ago, thank you!!! Some cards absolutely will not work without it.

[ivanpop]

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

I'm using Windows 10, blockchain official drivers and a number of different models of 470/480/570/580 4/8gb cards throughout all my rigs. These problems happen to all of them.

[mikkowendell]

Im still having problem with the freeze issue after doing some changing slot and replacing risers, changing drivers from 15.3 to the latest(cant control the fan), changing CM version from v6 to v10, checked the cables but there is nothing wrong, trying 4 cards from previous 5 cards running still freezes, doing GEN 1 from GEN 2 but all of them seems doesnt fix it. it still freezes. I removed the PSU thing since I have 1800w supply.
One thing I did not do it yet is reinstalling the OS because it would be my last resort and hope would fix it.

Also I noticed, after a couple of minutes when the CM runs, there is a cmd showing then it disappeared, several minutes afterthen the rig would freeze. Im really so confused because everything just started 3days ago, this R9 rig is running without any issue and I dont have any problem with it.

What I do now is Im trying to run it under SMOS and its running for 30minutes now, I will update this one later.

WIN10
MOBO z87 Deluxe
4x r9 290
1x r9 390
PSU 1050w + 750w

[eforius]

I can confirm I can have the same issue with Claymore freezing along with windows
I have the following setup

MB: Gigabyte H110-D3A LGA 1150
CPU: Celeron
RAM: 12GB
PSU: 2* 650 Corsair

GPU: 5* Asus DUAL RX580 8GB not modded

I have setup this rig with Windows 10 and after mining for 3 days it crashed and kept crashing every some hours after that. I tried to use EthOS and I have the same results.
I have tried all the settings I could possibly think of, changed many drivers, removed cards and added them back with the same result.

I have also seen that there is a GPU Hang error, which is not originating from a specific GPU but a random at any time

[kkourmousis]

Im still having problem with the freeze issue ......

I can confirm I can have the same issue with Claymore freezing along with windows

These look exactly like the problem I had. Sorry that my solution did not work for you guys as well.

It is possible that I have misunderstood the solution in my case. Maybe I did something else (except from lowering -cvddc) that fixed the problem and I missed that. I will be thinking of it through the day, trying to recall my actions during my tests.

One thing I can think of straight away is this: initially I lowered my -cclock from 1140 to 1130. After I did that, my next step was to lower my -cvddc from 875 to 850 (which I took as a solution)

Those things may seem insignificant for you, but I will say something that may ring a bell for you:

I have noticed that Claymore v.10.0 sometimes has some sort of "delayed effect". Changing a setting (lets say -cclock  or cvddc) will not take affect the first time you start the miner!
This has happened to me more than once. I have set a new value on a parameter, I run the miner, I did not notice the change I would expect, I restarted the miner and then the desired changes appeared.
This problem may have the same cause as this one:

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

which is a problem I have not yet resolved. A simple -minspeed will save me from trouble in this case, so I will not be spending much time on this one

So whatever you try as a "fix", restart your miner a couple of times to be sure

Hello, I´m using claymore together with Nicehashminer Legacy. The nsgpucnminer.exe is running 100% stable, without any rejected or stale Shares. But any round of DevFee Mining is cousing a disconnection and a reconnection, after 20 sec. After that, it is working fine again, unti the next DevFee appears.

DevFee:  Connection lost, retry in 20 sec...

How can i get ridd of these disconnections?

You can't, that is how the Dev Fee works.
From the OP..
"every hour the miner mines for 36 or 72 seconds for developer. "
This means it disconnects from your server, connects to the Dev Fee server then reconnects to your server every hour.

The "DevFee:  Connection lost, retry in 20 sec..." is your server noticing the disconnection for the Dev Fee mining and trying to reconnect, but it will not re-connect until the Dev Fee mining time is completed.

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.

[JustCauseBIH]

Don't blame machine...you said that you cut your fingers on blades, two times? Wow mate, maybe this is not for you?

[johndoe2]

Don't blame machine...you said that you cut your fingers on blades, two times? Wow mate, maybe this is not for you?

Dude, why don't you stick a finger into one of the cards and see what happens? I didn't do it on purpose. The main reason I'm changing the cards is because the hashrate drops to 1, not because I cut my finger etc.
