Hi, I've just started to try and mine etc solo and when I look at my claymore console it looks like this:

(redacted)

I don't know if it's working or not and frankly I'm a huge noob that's always mined via a pool.



You haven't found any blocks yet.

Mining solo with 80 MH you should do something like 10 or 12 days before finding a block.

ETH hashrate has been up at near record highs... and the difficulty has increased.  I recommend that you go back to mining in a pool.

Yes, I agree pool mining with that low of a hashrate is better with coins like ETH or ETC.

36524s you could mine coins such as Shift or Expanse if you want to try your hand at mining something solo. While on paper they might not be as profitable, in practice since you will have a decent shot at mining a block you will probably come out ahead. If profit is you main motive, then again pool mining would be your best bet.

Thanks guys, much appreciated.

I don't know if this "Bug" has been reported yet, but I've had problems with the fan control recently. There seems to be some oscillation going on in the control loop. Don't know what kind of controller you use, but I think stronger attenuation could solve the problem.

Here is a pic:
http://www.imagebam.com/image/938e35506278412

I only have the problem with 390 and 390x cards. 280x are running fine. GPU4 settles after ca. 1 hour, but GPU3 temperature still oscillates after days.

The temp is set to 76 °C for all cards. The fan speed oscillates between 25% (fan minimum) and 53%. The temperature between 70°C and 78°C.

I'm not going to check this coin until it is released, too busy. Sure they can find good dev for that amount.

Why not doing a XMR Miner for Nvidia too? Many guys here that would love to use it.

With this GPU you should wait at least a minute until DAG is generated.

@claymore
first, let me thank you for your nice work.
Do you have a miner, that fully support nvidia and AMD, for Linux, that works with Monero / xmr ?
thanks for info in advance !
Steve

I don't have Nvidia Monero miner, only AMD and recent versions work in Windows only.

Hi all! Sorry for my english!
I am new eth-miner user. I have installed Ubuntu server 15.10 on usb flash card. My system have 4 Gb ram and my videocards have video memore 4 Gb is too. I use ext2 file system. Could  I not use swap for etherium mining?

MY rx 480 stable at 29.5mhs at eth only but in duall mining is very poor i get only 25mhs eth + 250mhs sia
im use Rx 470 4gb + Rx 480 8gb , anyway to make the dualmining only in Rx 470? and my rx 480 running eth only ?
how to setting it ?

You can put in the command line to only run Ethereum.

Read the first page on how to set it up but I think its like " -mode 1"

Edit: Yes, -mode 1 in the setup will have it run Ethereum Only.


Run 2 instances of miner.  You need to change monitor port on one to prevent error messages about it.  You could also set different -dcri for each card, making the 480 dcri really low.

trying use this setting but still didn't work :
-mode 01
-mode 0.1
-mode -0-1

how to set it?
i want to the "0" vga running dual mining and the "1" running eth only

still no fancontrol with rx cards under linux ?
Please all linux users with rx cards waiting for this .. sure more important than colors in linux Wink

Be patient please. Now I'm working on updating Monero miner as promised (check its thread for details), it will take a couple of days. Then I will work on this task, as promised.

Hi Claymore,

When you have time do you think it's possible to implement this?

Hi Claymore,

I have an issue with DAG generation with some Hawaii cards that are extremely undervolted. The cards will mine perfectly without ever crashing, but at that low voltage they can't generate the initial DAG or the following DAG when it comes time to switch. They'll just crash while other cards in the system keep mining.

This can be solved by raising the voltage, obviously, but that means an extra 30-40w of power consumed on most of these cards which I'd like to avoid. Seems to me that there would possibly be two ways to fix this, while keeping the undervolts where they are.

1) Reduce the intensity of DAG generation? (Not sure this is possible...)

2) Add an option to the config file to lower GPU's core clock while generating the DAG? IE When mining use regular stable mining clock speed of 1100MHz, next DAG generation comes along drop to 900MHz while generating, when completed increase back to 1100MHz. Flags would be -cclock 1100 and -cclockdag 900.

Any thoughts? Hope this makes sense!

Thanks!

What voltage are you running your 290s at 1100?

1100 was just an example. I actually run Hawaii cards at 1055 with voltage as low as they'll go, generally 1.03-1.06v. (actual)

Do you dual mine or ETH solo? Because I think I ran mine at 0.95V once but it was slow (25MHs) solo only.


What is your power consumption?

at 25 mhs? I dont remember, it was less than 200 watts I think like 175watts each.

It was too slow and couldn't dual mine so I had to raise the voltage.

still no fancontrol with rx cards under linux ?
Please all linux users with rx cards waiting for this .. sure more important than colors in linux Wink

Be patient please. Now I'm working on updating Monero miner as promised (check its thread for details), it will take a couple of days. Then I will work on this task, as promised.

Hi Claymore,

When you have time do you think it's possible to implement this?

Hi Guys,

I have an issue, the fancontrol is only working with 1 of my 5 GPU, do you know why ?

Thx in advance
