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

[spiz0r]

Anybody has hasrates for older cards? 6970/6990 for SIA only mode?

@Claymore

Hey, played around with it. -gser 2 did not make a difference, but if I removed SIA minning and it works. Is there anyway to make both work?

On eth it is running no problems.

Thanks
-Art

I already told you all my thoughts.

@Claymore
EDIT:
Got it to work with lower SIA mining intensity. My guess is the cards wanted more power than the 2 x 8-pin connectors can provide mining both.

Thanks for the help, keep up that hard work.
 

You really need to have separate cables from psu to those 8-pin connectors if you are pushing that card. Otherwise you end up with melted connectors.

That is a good idea, i should have thought of that.

Thank you

how does gpu instability manifests it self while mining?    While gaming, we are presented with artifacts or even crashes.  But how does the miner behave?


Does the effective hashrate drops due to retrying the calculations?
Is there any sort of verification checking for computation errors?

I suppose the wisest thing to do is to check your undervolting with an error detecting benchmark (such as occt).



cheers

Sorry,
Why no boost on hashrate at 5.0ver by expanse mining?
On 4.7 it was about 68mh/s (2x 280x and 370)
Now it's equal to ethereum...

It works.. A little less 59mh/s instead of 68mh/s in dual mining...

The reaseon was... I have bad port 8008 instead of 8018 in my epools.text 0.o
I don't know why but somehow it was ...
(It works good with 4.7..
I have to investigate

Usually either CDM detects invalid ETH share by itself and does not send it to pool (number of such shares is shown in console miner stats). Or if something was really bad then OpenCL call (to GPU processors) hangs, miner detects this and restarts itself (or reboots the system depending on -r parameter).

[Claymore]

weird thing is that i didnt had this before, so dunno why its doing that suddenly

The answer is how long do you mine SIA on nanopool :-)

This was an issue with the pool that stopped/delayed responding to network requests. Miner probably had no explicit timeout check and decided that some execution thread was abnormally stopped. So it had to restart. On Windows some network errors detected much sooner (and as a side effect, Windows loses TCP connections instead of trying to wait a bit and recover). On Linux such connections still trying to recover for some time that exceed miner thread execution watchdog timeout. So there was no issue on Windows machines (miners just reconnected), but Linux miners aborted and restarted until pool recovered.

This definitely needs a fix because any network issue with the secondary coin pool should not abort mining the primary coin.

Yeah, as always, same code works in windows but fails in linux under some circumstances.
I will update linux version as soon as I can build it. My linux system decided not to load for some reason and now I have to reinstall it and all software, it takes some time. Nice OS.

As I said I fixed Exp issue but now I wonder why:
With Eth I have 700mhs SIA avg hashrate
and with Exp I have 900mhs

Claymore
I have two video cards is 7800, and 280x.
And the idea: 280h - 18Mh / s, 7800 - 12Mh / s

But if this is so, then the miner is not correctly displayed temperature.

Thank you, I really do not read to the end.

Thank you, I really do not read to the end.

You aren't alone

It's time to write a FAQ for questions asked on every page:

- what command option X means?
  RTFM, page 1, message 1. This is a copy of README.txt for the miner.

- how to mine using pool X?
  RTFM, page 1, message 1, examples section.

- why wrong temperature displayed?
  RTFM, page 1, message 1, KNOWN ISSUES section. Known issue of different ordering for mining and overdrive, thanks to AMD.

- can miner stop overheated GPU?
  Yes, -tstop option.

- why miner does not stop overheated GPU but exits?
  Probably, wrong -di option. See question above about wrong temperatures.

- why this command line doesn't work (escaping '&')?
  Char '&' in command line means command separator, to use it in command line either quote string with "", or escape '&' (use ^& on Windows).
  No need to do this in *pools.txt or config.txt.

- how to mine Decred or Sia ONLY with this Ethereum Dual miner?
  No way. It is Ethereum miner with extra bonus coins. To mine extra coins only use other miners.

- why Ethereum hashrate in Dual mode is higher than in Single mode?
  Hardware feature, accept it as an extra bonus.

- is 15.12 driver mandatory?
  Usually latest drivers work well. But there are some reports of people where they don't. So 15.12 is known good version.

- will newer drivers have higher/lower hashrate?
  Usually no, but it depends... Check for yourself.

- why miner does not show temperatures for RX 480 cards?
  They use newer overdrive API which is not yet published by AMD.

- why miner on Linux with stock card settings gives lower hashrate than on Windows?
  This probably is the difference in time calculations on both platforms. In reality the accepted hashrate is usually the same.

- why -cclock/-mclock options do not work?
  Sometimes they do not work. Use Afterburner or Trixx on Windows, atitweak and other tools on Linux instead.

- why my GPU is 10C hotter in Dual mode?
  This is a price for the extra work done. It also consumes more power, so make sure your PSU has sufficient power.

- can the temperature be lowered in Dual mode?
  Yes, -dcri option. Also see -tt and -ttdcr.

- how can I undervolt my cards on Linux?
  Usually only by flashing modified GPU BIOS. Unfortunately, no standard way of doing so.

Please add more by your taste.

The problem is if I add FAQ to first post at the end, many people won't reach it. If I add it at top, many people won't read anything after FAQ
Sometimes I feel that I spent a lot of time for creating readme for nothing.
Anyway, I will add FAQ soon, and it's not going to be too short; other popular questions are:

- Why pool shows less hashrate than miner.
- Windows 10 marks miner as a virus.
- I see only one card via RDC.
- I see only one card instead of two when CrossFire is enabled.
- Miner works in ETH-only mode but crashes in dual mode (check PSU).

Just a suggestion, you can put the FAQ and other important links in your signature for faster access

[osnwt]

- if I enable internal Intel CPU video, miner doesn't see any AMD cards...

I can assure you that at least one guy (me) reads all documents and checks what's new after new releases. Even if not use all, it is good to know what is possible to do with it. But FAQ is necessary just to point people to it like "Read here, question #100500"    Helps very well.

This is something else, but I keep getting this unsupported overdrive version error messages in the log with 3x 480x, they are mining nicely tho, it's just annoying,
what can this be?

Added to OP:

- Temperature/fan management for RX 480 is not supported currently. 480 card uses Overdrive v7, latest ADK SDK (v9) supports Overdrive v6, so currently AMD has no public documents about Overdrive v7 and therefore there is no way to manage temperature/fans/clocks of 480 cards.

Not exactly.

precisely from page 4 for RX series.

How come nobody actually reads???

Don't dual mine SIA if you are running out of power or your miners are overheating, mine it directly without ETH and you will make slightly more until the next difficulty retarget.

7970/280x mines at 900MHS/s $3 per day per GPU ! You won't make that much with ETH currently.

It was $15 per a card middle winter. Its over now

Soo Claymore,

Have u considered setting up a claymore pool?
With the coins your miner mines?

Id love to see a ETH/DCR/SIA(and more)-pool.

I bet it would be a smashing success, and with a 1% fee or something, u would make a decent amount on that too. (in addition to the miner fee)

[aistto]

Mr. Claymore

log - https://yadi.sk/d/q-1KR2lNtCyE2

miner suddenly lost connection to pool, in log "23:32:20:978"
restarting miner fix it.

is it pool issue or miner?

and maybe you could add autorestart in this case?

I have 2 GPU HD7970 on Windows 7 64 bit, all works fine until I use teamviewer for remote connection, the AMD driver (Crimson 15.12) stop to work and from GPU-Z and MSI Afterburner I can not see any GPU infos. I have try to reinstall the AMD driver but the problem is still present.
The monitor is not connected to the Computer.

I had lower hash rates and and driver crashing when I started the miner while connected in using teamviewer. The fix I found was adding a shortcut to the start.bat file into windows startup folder. Stable for over 600 hours.

So on every boot the miner will launch. I also made the windows user auto login, and added this line to the .bat file:

timeout /t 30 /nobreak

That line gives a 30 second delay before the .bat file executes the next command in the file.
