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

[bardacuda]

Since building my first rig last June, i've always had this rock-stable settings for six of my Asus Dual OC 580s 8GB Samsung memory

-cclock 1260
-mclock 2050
-cvddc 925mV
-mvddc 925mV

This yields me a constant 29.1 to 29.3 across all cards (175 total) and pulls about 1175 up to 1200w. High, I know but they go for weeks until needing a restart.

Earlier this week, I played with them again to squeeze in few more Mh. These are my settings:
-cclock 1140
-mclock 2075
-cvddc 875
-mvddc 875

They average a total of 177.5 now and cards hashes from 29.5 up to 30.0. But the best thing is they now only pull 1035w dual-mining with DCR.

Wow thats excellent results for those cards. I've checked some forums and noone was able to get those numbers.
I've tried different tweaked BIOS (even from RX480) which gave same results but nothing was stable for more than few hrs.
With blockchain driver the only stable bios was original with 1750 straps and -cvddc 1000 (28MHz).
Which BIOS do you use?

That's actually not great. Power usage could be much lower. For example I have a 4-card rig that pulls ~580W from the wall (with a bronze PSU so would prob be more like 550W with a gold). The rig pulls 80W @ idle so each card pulls about 125W under load. Stable for over 530 hours w/ over 29MH/s per card. If this were a 6-card rig it should only be pulling between 780W (gold PSU) to 830W (bronze PSU).

EDIT: Ahh nvm...just noticed he is dual mining DCR. Different story.

same cards giving me pain when installed 8 per rig, leftover 4 run smoothly at over 30MH. usual 1500 straps, ~850-880mv, 1180&2100 (elpida is nice these days)

Claymore i need to monitor rigs with php, is there any example for such language, i know there is nodejs monitoring tool but wasn't able to find any php example, do you have something or can provide as an test/example ?, thanks.

It's just Json, you can write monitoring in any language that can create json queries and parse the result. Its so Easy

Edit : PHP Can do it, HTML5 can do it, and almost every programming language have abilities to interact with json.

i did not know that, json is easy, but how to get to that json, if i set remote port, how do i connect to claymore api, socket way ?
is there a way to switch off or on card or restart claymore via api ?

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.

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.

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.

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

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

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.
