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

[Etherion]

Hellow Claymore.
I have one problem. In the rig i have two HIS RX 470/ All works fine exept monitoring. Miner show only one(the first) gpu stats(temp. and fan).

Disable Crossfire

I had the same thing if i use remote connect and then starting Claymore. But when i connect using TeamViewer and restarts te miner it shows all the cards temp and fans speeds

Anybody runs CDM with 6 RX470 cards? I've been trying, still no success.

On Linux single card works fine, 2+ are visible but give weird hash rates (too low and unstable).
On W7 only 4 cards work, with 6-card mod ANY 5 of 6 cards work, one gives error code 43. I can change it to other, but up to 5 working.
On W8 5 of 6 cards work without any mods, one gives error. Seems the same issue as on W7 with 6-card mod.
On W10 all 6 cards are visible, but CDM shows errors creating DAG on 2-4 cards (different every time), -lidag does not help.

CDM 7.2, amdgpu pro on Linux, Win drivers 16.9.2, ASRock H81 Pro BTC, Sapphire RX470 Nitro+ 4GB, PSU 1300W, different risers (some strips and some USB ones, while I am waiting for a pack of 6 USB risers).

W7 and W8 work but seems like insufficient PCI-E resources to run 6 cards. Starting the 6th card initializes it and immediately gives code 43. ANY of 6.... So no hardware issues, but something else. Mining on any 5 cards is stable.

W10 and Linux - I have no idea what happens at all.

Ram / swap file size issues on w10
Either serialize cards init (-gser option) or add some ram or check real swap file size

AFAIR, I tried -gser with no success. I think this option serializes OpenCL code compilation (miner writes "POOL/SOLO version" and builds the code, thus delay). Then it runs the same DAG build process on all GPUs at the same time, and then a memory size should not make any sense.

I forgot to manually increase virtual RAM size, but I have 8G RAM installed and think that at least the same amount was added by paging, so it should not be a problem.

I got this precise issue when my swap file was too small. Random gpu wasn't compiling dag while others where okay (up to 2 gpu failed depending of swap size)
Looking @ your rig's specs, I misread you had 4 Gb :/

I sometimes get a hang if the driver crash on one of the cards in the rig. How can I restart the miner f.ex every 3 hours? or more? Did you make a restart parameter?

1st post, -r option

[aaronsace]

'-mode 1' works fine but I've found a bug when setting the '-mode' for a single GPU when a '-dcoin' is set (I have version 7.2):

'-mode' works with these commands: '-dcoin dcr -mode 1-0' or '-mode 1-0'

'-mode' is ignored with this command: '-dcoin lbc -mode 1-0'

"-r" sets restart time. "-r 180" equals restart every 3 hours

If, you are using Nvidia cards, disabling "HDMI drivers" in Device Manager for each GPU really helps with driver crashes not leading to whole PC crashes.

Hope, that is helpful.

That's great, thanks for the quick response. Can I just say that your miner is amazing BTW, 33 mh/s on an AMD 290!

@Claymore, few questions:

1) -cclock: you wrote "you can overclock only", but it seems not to be true for, at least, Windows and Polaris. My 470x can be underclocked (GPU set to 1150 for all states).
2) Any chance to support -cclock and -mclock on Linux for amdgpu-pro drivers (for Polaris)? It is not said "unsupported on Linux", but does not work for me (mem can't be set to 1950 using this).
3) Any chance to support -cvddc and -mvddc on Linux for amdgpu-pro drivers?
4) Are older cards like 7950/7970 supported using amdgpu-pro drivers on Linux?
5) There is an issue on Windows when used -*clock commands: they are applied at some init stage, but for my 470x it instantly changes hashrates only for the card with monitor connected. I can stop and resume other cards for changes to take effect (and show correct/new hashrate), but probably makes sense to fix it somehow, so miner shows correct hashrates after applying values. Of course, if you run it for 2+ time, drivers keep settings and there is no that effect. Still, it is surprising when you run minr with some value and it is not reflected in hashrates.

1. AMD disabled underclocking in theri drivers in past. May be it enabled it again in recent drivers, I did not check it.
2. Linux requires root access for it, I remember someone said that even sudo is not working.
3. Did not check if it is possible.
4. I did not check it.
5. So if I take two 4xx cards, start miner with -*clock option and it will change clocks only for one card?

5. No. In short: changing memory clock using any tool does not change displayed hashrate until miner restarted or card stopped/resumed. Except a card with monitor connected: for it new hashrate is shown instantly.

When I change memory freq using any tool (WattTool) for a single card while miner is running, it instantly changes displayed hashrate only if the card has connected monitor (tested on Rx470). For headless cards the hashrate shown is not changed until miner restarted or card stopped/resumed. That seems to be a feature (@All: please confirm, but I saw someone complained for the same issue).
When you change freq using miner cmdline, and previous freq was not the same, miner sets freq but shows hashrate for old freq until restarted.

5. Some cards I have, wattman doesn't allow changing clocks/voltages unless I pause miner.  I didn't think of if monitor was connected.  I have some display emulators I got for $15 that helps with VNC, but not sure it would be worth it for more than that...

It is very strange for me because sometimes displayed hashrate changing when I change ram frequency,
sometimes it doesn't react sometimes it react for gpu frequency though

So, I have been using CDM 7.2 for about 5 days now on my W7 system. I was finally able to reduce my wattage pull through Wattman setting (and disabling dual mining), but am still stuck on a paltry 20.75 Mh/s on ETH per each of my MSI RX 470's.  I have tried everything on the CDM side, such as setting ETH intensity to the max of 16 in my command line, adding in all 5 of the recommended setx lines, set my virtual memory to 24GB, etc. None of this moved the needle at all.

So, I am now trying the overclocking route before getting into modding the bios on these.  A few things are perplexing though. In my Wattman, each of the 4 GPU's can only be increased from 1650 default to 1700.  These seems like a very low limit to me and setting all 4 to 1700 had zero impact.

So, using Afterburner, it actually gave me the option to raise Memory Clock all the way to 2100.  I only tried 1850 and applied to all 4 GPUs but yet again, absolutely NO impact... all 4 still mining at exactly 20.75. So, my question is, am I doing something wrong?  Shouldn't raising the the clock speed on these yield at least a 5-10% bump in mining hash-rate?  Or am I completely off base here?

I know of many people using these cards that have achieved 23+ right out of the box, so still trying to figure out why I cannot get close to that mark.

Please update your driver version..
I have same issue with my rx 480 before update drivers I was able only to increase RAM frequency from 2000 to 2100Mhz, after update I can set 2250Mhz in Wattman

WooHoo! It solved the issue. Win10 original drivers + 16GB paging file = success.
I really did not expect that it will require manual paging file with 8GB or system RAM since miner process used only ~250MB (as shown by Windows).
Thank you, now it works as it should.

Glad it helped
Seems like the os must account some storage capability when dealing with 6 dags, not really using it. Reminds me of old Id Software games, crashing without swapfile but happy with 1 Mb of it (if you had enough ram of course)

I was using -cclock for a while - it works good. (in fact it's the fastest way to identify cards if you set something like 1010, 1020, 1030, etc...)
Watttool would apply values immediately if you uninstall the AMD drivers crap and just point devices to the driver dir.

Hello.is it possible to add a function of one time connection try and exit if failed?want to make it work with multialgo switching on miningpoolhub...

[Cryptozillah]

How do i apply the "-lidag" option correctly ? I want all gpus to use low intensity at the dag part.
I messed around today but did not get it to work.
I am using the 7.1 version of the miner, does that version support lidag ? 7.2 version dont work that good with my RX rigs somehow.

Sometimes some of my rigs freeze at dag creation so i guess this option would be good.

Thank you very much.
I use it for gaming as well, so do you think this is the best?

There is also one with a higher core clock rate, what do you think?

For Ethereum mining it's more about the memory speed not the processor.

Both of those 8 GB cards you linked have Effective Memory Clock: 8000 MHz.  If you look at the specifications for the 4 GB version it only has 7000 MHz memory.

For gaming (which you said you do) you would want the higher core clock rate.  So the second one would overall be better. (IMHO) Buy me one and send me one for gaming and I'll let you know

I got the overclocked one.
OCing the memory speed helps ETH more than the GPU speed?
I noticed it helped SIA/LBRY, but not much for ETH.

I got it up to 1360 and stable it seems at 1140 cvddc.
25 ETH 44 LBRY

What should my memory speed, core speed, and cv/mvddc be do you think?
Electric is cheap, and I need the heat any way, so going for as much speed as possible without hurting the card.
Temps are staying around 78c.

I run 1342MHz (stock OC for card) @1030mv.  Undervolting will allow card to maintain boost clocks, increasing performance (without setting crazy power limit). Use GPU-Z to check actual core clocks....

Less power means less stress on VRMs, GPU, fans, and possibly PSU.  I prefer ~70-73C temps, which I get with ~60% fan, and 80F ambient.  Cards all on risers.  Night they run like 64C @50% fan (~60F ambient).
