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

[Claymore]

Hey Claymore, will you support Zcash mining with your software? lots of miners are expecting that coin release.

I will check this coin when it is released, right now I'm busy with other things.

Zcash will be scrypt-n from what i read.

Guys I am trying to set up the following rig:

Asrock H81 pro btc
16 gb ram DDR3
6 x XFX RX480 8gb
6 x PCI 1x 16
SSD external memory
Intel Pentium G3260
1200 w PSU
WIN 10 64 bit

I would like to install the latest version of Claymore's dual miner on it, the problem is that the PC can not even run the 6 GPU's all the same time apparently, without anything installed on it yet, but Windows (I am helping which is setting it up and we are about 2000 miles far from each other, so this doesn't help).

Windows starts normally if only 3 GPUs are connected, but a black screen will come off if we try to connect all the 6 GPU's.

Any idea?

Also which drivers would you recommend for the XFX RX480 8gb? Is the latest crimson driver ok?

Any help would be deeply appreciated, thank you!

I have two rigs running 6 Sapphire 480 Nitro each with that mobo.

Using powered usb risers, no need to used the mobo molex connectors

Win10 x64 + AMD drivers 16.9.1

Very stable, no problems whatsoever

ZCash will use Equihash as an hashing algorithm, which is an asymmetric memory-hard PoW algorithm based on the generalized birthday problem. It relies on high RAM requirements to bottleneck the generation of proofs and making ASIC development unfeasible, much like Ethereum.

Did you power the molex connector on the ASrock mobo?

For multi GPU setup, you need this for extra power going to the GPUs in addition to powered USB risers.

Plus... you also need to set minimum 16GB virtual windows memory.

I don't know why lots of people think you need to power the molex on mobo.  If using the 1x-16x powered USB risers, they are completely unnecessary.  The risers are all powered, there is 0.00000w going through the slots on the motherboard.  The molex on mobo are for if you are using non powered risers.  I have that board, and it will run fine with 6 cards, nothing plugged into mobo.

Bios throws error telling you to plug in the 4-pin molex power on the motherboard.

@claymore

I have a rig with 4 GPU's
Intel HD4400
HD 7870 XT
(2)GTX 1060 3GB

Claymore's dual miner ... 7.0

Issues is that only the temps are displayed for the Nvidia cards and not the AMD card?  Is this an issue with the video being plugged into the Intel igpu and not the AMD card or something else?

Log file contains info about the reason.

Didn't check log file but pretty sure that it was the intel igpu that was causing your program to not read the temps from my amd card because after disabling the onboard video and plugging the display directly into the amd card it started reading the amd cards temps after a reboot.  Is there anyway  to force the AMD api to read temps when it is using the Intel opencl platform?

Eth dcr mining is stable now with good temp

You can tell it to not show that message.  I am currently mining with that board with 5 cards, all powered risers, no molex plugged into the board.

   Try like separate the main GPU razer with only one SATA, HDD + 1 gpu - sata, 2x gpu-sata, 2x gpu-sata

[scryptr]

A GOOD RULE-OF-THUMB--

Place no more than 2 GPU's powered risers on a single SATA cable.  Placing the powered riser for GPU 0 on a single SATA cable, along with a HDD or other low powered device, may also be good policy.       --scryptr

"-etha 2" will help you. Within 24 hours I will release an update, this option will be set automatically on Linux+gpupro.

-etha 2  reduce hash rate 0,2Mh on each RX480 card - 1Mh in 5 card rig.

That's the price we have to pay for Linux+gpupro drivers. Better use Windows.

Don't power any 480s from any SATA cable.

Any idea as to why I would be getting rejects all of the sudden? When it was Epoc 74 and 75, I never got a single reject with my 2x AMD 480s.

Now that Epoc 76 is here, my hashrate has dropped by 0.1 MHs per card ( expected) and I am now getting rejects. It is still a very very low percentage. This morning it was 5,000 accepted shares and 46 rejected.

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!

Option #1 is better, PM me and in a day I will send you a version for tests.

[Claymore]

v7.1:

- now "-etha 2" is set automatically for Linux and 4xx cards. You can change it by specifying "-etha" directly if necessary.
- if miner manages fans, it returns management back to drivers at closing.
- added text coloring in Linux version. You can use "-colors 0" option to disable it if necessary.
- several minor improvements and bug fixes.
- EthMan: added ability to start .bat file if miner has problems.
- EthMan: added support for CryptoNote miner.

Any real difference between etha 1 and etha 2 for rx470 ?  using etha 1 and not seeing much incorrect shares.  0 out of 1900 so far.
