what motherboard?
some motherboards dont like more than 4âŚ
are you set to PCIE gen2?
do you have a setting for your 16x slots in bios?
like 16x,0x,0x
8x,8x,0x?
8x,4x,4x
try setting that to 8x,4x,4x if you do
Try DDU to uninstall and install 16.10.3
if that fails, i recommend trying ubuntu 16.04 as that works much better for my and 7-GPU rig
One stratum connection per rig, not per card, and stratum doesnât âpingâ anything, like âget workâ, it listens for new work sent from the pool. Thatâs the whole idea. Iâve run 20 rigs, 120 GPUs, for 9 months on ETH, and I have a stale rate ~0.5% on ethermine.org, so thereâs no issue with having a stratum connection to a pool for each rigs, plus the up-time for the farm is much better. But, hey, what do I know? Cheers!
Is there a way to record the terminal output of Silentarmy to a log file with each line having a timestamp? A script of a kind. I need that to troubleshoot overclocking. I just woke up to see my rig frozen, had to restart it and there was no way to find which card was the culprit.
Since youâve been mining for 9 months, I have a questionâŚ
How often do rigs fail? Do GPUs fail in any way with time? Do you have to provide replacement for certain equipment?
@lexele Yes the nicehash problem are solved (compatibility with stratum servers fixing 17 nonce bytes (eg. nicehash) ¡ mbevand/silentarmy@0d371a9 ¡ GitHub). You will still see warnings about âclient.reconnectâ but you can safely ignore them.
@excessu If you are at 45% CPU usage, you may notice at most a +5-10% improvement by switching to a faster CPU. I would like to say though that with about ~1 dayâs worth of work I could significantly reduce CPU usage to less than <1%. I am not sure when I will have time to work on this improvement though. What Iâm saying is maybe donât go out and buy a fancy CPU just now.
That would be wonderful! Thanks! Just forget that day job - youâve got more important things to do 
Thatâs a complicated question 
It depends. But since most miners are pushing their rigs for every last hash, with undervolting and overclocking, max GPU density per rig, etc., yes the rigs burp more than youâd like. Warm weather is a bugger, too. Think serious ventilation. I donât think most miners keep spare equipment, since youâre always wanting to put that spare stuff together and mine with it Iâve actually only had 1 GPU fail outright, but they do get hung periodically, and that sometimes requires a complete power-down to clear it. Risers are the weakest link, with a good deal of DOA and infant mortality, but once they run for a couple weeks, theyâre usually solid. They can cause countless failure scenarios, so they are not quick to troubleshoot. MB failures would be the next most frequent problem, at least with the âfor minersâ MBs they make (H81 and H97, 1 x16 + 5 x1 slots).
Pipe the SA output into a script, write a timestamp, append the input log line, repeat. Or just mod the source code to add a timestamp to the logging print statement.
Is the Equihash Solver for Silent Army necessary if Iâm only doing pool mining? (Iâve never coded in my life, donât really know any computer languages, and have been working with a terminal / line commands in Linux Ubuntu for only 2 weeks â a n00b in all respects.) For me less is more, so can I just skip that part. I have two AMD R9 Nanos Iâd like to fire up.
You canât mine anything without sa-solver; the solver is the miner, whether youâre on a pool or not. Silentarmy is a python blob that âjustâ handles the stratum connection to the pool to receive work to mine on (which it sends out to all the sa-solver processes) and return solutions to the pool (which come from the sa-solver processes).
which card and what mod BIOS?
So today marks the day that ETH becomes more profitable than ZEC for minersâŚ
I though you all might find this chart interestingâŚ
It shows that the current downfall start at the exact time that CLaymore released his SilentArmy windows cloneâŚ
It looks as thought prior to his release, the price was stabilizing at just over 1 BTC⌠but thenâŚ
do you think the current downfall is due to too many of claymoreâs miners mining and selling off fast? or do you think its just a co-incidence? curious as to your thoughts⌠this may bring an end to the fun here on the forums⌠interest may just die at this point. its really too bad i had a fun time.
How low do you think the price can go? 0.1 BTC? 0.05 BT? 0.2 BTC?
I suppose there comes a point where cloud mining keeps ZEC alive with CPRâŚ
And I suppse there comes a point where those cloud miners decide to hold rather than sell - but what is that point seems to be my curiosityâŚ
Thank you. Very clear explanation and very helpful. Ok, then, have my work cut out for me with all those nonces and whatnot. Will almost certainly need to find someone to help me follow the instructions w/out screwing things up.
Hi there
are all of you using intel boards for 6/7 gpu rigs or is someone using amd board with 6 PCIe slots?
The price should stabilize around where it is now. At least for a while. Tomorrow some miners will be moving their rigs back to ETH. That means that a huge crowd no longer needs to sell their mined coins on a daily basis which will alleviate the oversupply pressure from the market. Bulls should have their way.
BTW ZEC is still more profitable on 280 rigs with Claymore while these cards are becoming pathetic on ETH.
yes i do realize some crap cards might still get stuck mining ZEC
price may stabilize today, i agree also, but we will have to see
At this point zcash might not be profitable to mine 
Attempting to install SilentArmy, and am in over my head. Iâm now at the part where it says, "You may need to specify the paths to the locations of your OpenCL C headers
and libOpenCL, so if the Makefile does not find them (which it didnât):
$ make OPENCL_HEADERS=/path/here LIBOPENCL=/path/there
Iâm sure I donât put path/here and path/there, but no clue what to put. Help a noob for good karma.
Saw this on store window last year, âKarma means I can go to sleep peacefully each night knowing that all the people I treated badly had it coming.â
