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

[Vann]

Windows 1709 update that came out today breaks Claymore 10. It says the opencl.dll is now missing and will not start.

Update: Reinstalling the video card driver corrected the problem. Turns out the Windows 1709 Update dumps the video driver.

is amd blockchain driver still compatible with win10 ver 1709? yesterday i reformatted 1 rig because of this unwantted upgrade.

The AMD blockchain driver works with the v1709 build but the problem is the Windows UI becomes unresponsive and unstable. I did a clean install back to v1703 until a new driver is released. Supposedly there will be an updated driver later this year that will increase the maximum limit of 8 of the same GPU type in Windows 10.

Good grief, thank you so much for that information!  You probably just saved me two days of trying to figure out wth was going on since I (again) forgot to turn off the stupid auto-update.

Same happen to me and this isn't the first time with Windows updates, by now i disabled the automatic updates these can make problems with my rig..

Hello,

does someone facing hard reboot (without any info .. just like on/off on PSU) with Claymore v10.0 on windows when mining (in dual mode) and connection to both pools get lost?

Could be too much draw on the PSU? Really need to provide more detail on your setup though.

It's not PSU i guess. It is 100% reproducible just by pulling out ethernet cable from lan socket. It crashes immediately during restore of the work(when reconnected to pool). Rigs are running days without crash, but when cable pulled off or some problem happened on network, it goes to hard reboot.

When I still had my 8-gpu rig consisting of MSI Gaming X 580 4gb elpidas, I'm having similar problems as you. They're smooth and all but they only hash 29.6 if all eight cards are connected.

If I only plug 4-5 cards, they hash a terrific 30.1 up to 30.3 each.

I've created a thread here, in another board and even in ethermining sub of reddit but apparently, not too many miners have 8-gpu rigs to contribute their thoughts.

I'm in the process of building 8x Nitro+ 580s on Saturday and I hope and pray that it's not going to be the same experience as the Gaming X's.

lol... I've got seven 570 rigs with 8*MSI gaming, 8*asus expedition, and 8*Nitro+ mostly elpida, some of those also have 2-4*1060 Palits 6Gb all on Asrock h100 btc.
The issues I'm having with dual claymore v10 & blockchain drivers:

1) the main problem is that some cards like to go down to 24-25 from regular 28-29. On some rigs first boot is almost guaranteed to be this way, often it's 28,25,25,25,25,25,25,25... but on anothers it may come in a few hours after reboot. (if it comes later the cards become very unstable and often crash, even on 1800Mem and 1080Core settings. Didn't check the stock timings yet...) Sometimes these all can lead to win hung, but now just installed watchdogs, so this is partially solved:)

2) Another issue is that Nvidia may fail to allocate dag and several reboots(sometimes even 5-6) may be required to get rid of this error. Also may lead to win hang.

3) And finally extremely irritating issue with EthMon: I've got one rig (one of the clones, so nothing special about it) that after 10-20 hours looses connection to EthMon, and will appear red, although working fine.

Curious what mobo do you use with your 8x gpu rigs?

Also, are you having a similar problem as mine? 8x gpus mine slower when all is connected ? or they mine the same as connecting a single GPU?

Hello. First, just want to thank this forum for being an excellent resource in helping me to get into mining. Thank you!

Question, I feel like I've been seeing a lot of DEVFEE mining as I'm running Claymore 10.0. So I did a count on the number of "Accepted Shares" vs the number of "DevFee Accepted share". For every 100 "Accepted Share" for me, there are 17 "Dev Fee Accepted Share".  Does this mean that 17% of the shares I am mining are going to Claymore?  The actual breakdown was 1,434 "Accepted Share" to 250 "DevFee Accepted Share".

Thank you for your help!!

It's probably connecting do a different pool with lower difficulty shares for the dev fee. Check your logs.

Using 8x GPU Nvidia GTX 1070 FE, on windows, Asus Prime z270-a works like a charm 32.100 Mh/s on each card total power 860Watt/h. but i had a big time hassle while i was trying to install the 8th card cos of the cheap m2->PCIe connector , everything  solved when i use a better m2 ->PCIe from amazon --->> Explomos M.2 Key

The diff isn't The same for our mining than dev mining? I think yes but, after Byzantium fork the diff is low. The stale shares rate increase (ethermine) but I think they are adjusting it, I don't know the dev shares rate but I check it for compare. How is your hashrste? Your average shares? I have 0,45 ETH rejected every hour.

[bardacuda]

The diff depends on the pool, and even the socket. Even then if the dev fee uses the same pool and socket, but it's a variable difficulty socket, then the difficulty can be set lower when it makes the new connection and probably won't even settle in to your normal difficulty by the time the dev fee mining is over.

That's why you should look at the amount of time spent dev fee mining, rather than purely the number of shares. Number of shares doesn't mean anything if you don't know the difficulty of each.

[ubuntus]

Thanks for the update!

This is a major software that most miners use and its good to see a nice dev team on it!

Great feedback! Thank you!  How can i double check the amount of time the program mines on behalf of dev?

What MB settings did you use? And which M.2 port is used to connect?

Hello,

Just want to know how I can put a minus value on core voltage. I know that core voltage is set by using -cvddc

-cvddc set target GPU core voltage, multiplied by 1000. For example, "-cvddc 1050" means 1.05V

If I want to put -96mv, how do I calculate this ?

Thank you

Just use msi afterburner or asus strixx, setting overclock on claymore is buggy sometimes.
