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

[AzzAz]

Im brand new here, trying to mine eth with a G73 laptop running windows 7 w/ a GTX 460M, currently getting this error:

Any help would be greatly appreciated!, Thank you

There are much easier ways to fry that lap

@Claymore
The '-r -1' command line option is not working correctly in version 10; it still retries the initialization instead of closing.

I did not change anything related to "-r" option in v10.0, so the same issue must be in previous version too. Anyway, I will check it and fix in next update.

Thank you.

I've been using Claymore on an unstable system - trying to narrow down the errors to stabilize the system but it is still crashing.  It has never mined for more than a day or so without crashing.

Now the console output gives zero indication of error, it just crashes or reboots after several hours or nearly immediately.

Z170A SLI PLUS
5 x gigabyte 1070
1200W EVGA platinum
win 8.1 64

Does it crash without mining activity? Did you try 1 card? Did  you try default settings for everything?

IF you are trying to break your laptop - just give it to me.

Just upgraded from 9.8.... Zero difference...
9.7 to 9.8 was also zero difference.
I am running 6x MSI RX 580 Gaming 8GB, and would love to know how I can increase the hashing  



Thanks much!

What have you tried? What have you done so far?

[fr4nkthetank]

to increase hashrate, you need to mod your bios and edit your memory timings.  Also, underclock and undervolt to save electricity and overclock the memory.  Its not plug and play, but there many guides out there, youtube videos and bitcointalk posts.  You could always check my website there is a section on bios flashing.  at your own risk.  no one said it was easy but for a little effort you will get 30% more hashrate for less power usage.

Is decredpool.org down? 

[viking1978]

I am building a rig with 13 GPU (8*AMD+5*Nvidia). I am wondering how can i overclock and undervolt in this scenario.

let's assume GPU#0-7 is AMD, GPU  #8-12 is Nvidia. Take mclock as an example, do i have to specify the nvidia cards' memory clock since claymore does not support.

-mclock 2180,2050,2180,2050,2050,2180,2180,2180,XXXX,XXXX,XXXX,XXXX,XXXX

My bone-stock Asus Dual OC hashes at 24Mh/s out of the box.
I've seen guys push Gaming X cards up to 31 especially when memory type is Samsung.

Copy straps 1750>2000 or boost your memory clock up to 2100 or 2150.

@topic:

Tried v10 this morning, just copying and pasting my config.txt and dpools.txt onto the new version.

Verdict:
My overclock/underclock and undervolt are set in bios so I can say that it still bypasses set voltage. You have to do -cvddc and -mvddc on the cofig for it to work BUT voltage offsets are very unstable - jumps from 1.025 to .900mV in 2-3 seconds. About 15-20w higher power draw too as per GPU-Z and around 200w more at the wall.

Since I can control my undervolts in Trixx better, i'll just be using v9.8 for now.

[sodathief]

Wow this is really cool! I had a 20mh/s boost in ETH and like 1k mh/s in DCR dual mining. Only one problem though: I seem to randomly lose connection to my pools now. I have been mining in simplemining and haven't had issues, but I haven't had these hash rates either  . Claymore reconnects fine but its pretty weird.

Anyone else get abnormal connection issues after making a change to os, voltage, or clocks? I set everything in theclaymore config btw.

Error message: Socket was closed remotely (by pool)

[bdon22]

I am finally able to use the latest AMD blockchain drivers now with this release. Previously I wasn't able to get my OC to work even with AB Beta 16 and Trixx.

The only problem I have now is that I am getting around ~5% rejected shares dual mining DCR.

Anyone else get the same?

[Jackkyy]

Whats a hashrate with VEga 64 and Vega 56

thanks a lot

[waster29]

Hi Claymore .
Can you please add allcoins ubq next update .. Thats will be great
Thanks

[HashashInc]

Great job claymore finally i can raise the clock on that rx  gained 1.5mh/s for each card,keep updating !

[cuongmn64]

@Claymore, I don't know this is a bug but every time there is a rejected share and miner reconnect, it just hang my computer. Because of this, v10.0 is really unstable for me some how. The voltage control is amazing though.

PSU/RISER PROBLEM LIKELY--

I agree with Klassje.  It is likely that a riser is bad.  Old, skinny-version risers get really hot and sometimes melt with dual-mining, and even new risers go bad.  It is interesting to note that if the problem occurs, the "511C" figure is common.  I have had the same readout; the card was good but the riser was bad.
I would stop the rig and change risers before mining again.      --scryptr

And which risers are better to take?
I have a 6 version with a black wire....like these ones: https://ru.aliexpress.com/store/product/Black-0-6M-PCI-Express-PCI-E-1X-to-16X-Riser-Card-Adapter-PCIE-Extender-with/1826735_32789606816.html?spm=a2g0v.12010608.0.0.81bf1c12u9nXF

Better change your nickname to something more appropriate to the content of your posts.

As others said, you must do different things - optimize BIOS settings, change frequencies, voltages and configurations. In the first step you should use the new AMD beta driver for blockchain(at AMD page) then use MSI-Afterburner to find out the best frequencies for GPU and MEM. You can change the values during claymore is running and see the changes in hashrate directly. Generally start by reducing GPU-clock and increase the MEM clock. Generally start the optimization work with only one card in the rig !
Another suggestion - use W10 64bit. You can expect at the end up to 31,5 Mh/s with RX580. When you change the BIOS later keep in mind you need tools for editing and flashing BIOS. And you need a driver patcher ... you can find everything by search. Good luck

[karlo-fan]

I just uninstall old AMD drivers by DDU and install Radeon Beta Blockchain (23 aug) Driver on Windows 7 64bit but I can't run Claymore's Dual miner, when I try to run, it crashes at same time.
Is there any solution how to fix this problem?
