Am a long time miner and have been with coinmine.pl since the beginning (you were one of the first ZEC pools and commanded a high global hash rate in the early days). I have recommended you to many of my friends.

I understand the concept of luck, and that pools require constant maintenance to run optimally.

Let us take the last month to provide a good aggregate versus say suprnova:

Coinmine.pl



Suprnova



101 blocks versus 616? thats too long a time span for a blip of bad luck.

coinmine.pl has a healthy amount of shares in that time too (3.5x  versus suprnova) so plenty of hash power there.

Either something fishy is going on, the pool is being scammed, or is in a poor state of maintenance (we've has some outages recently)

 I cant go on with this and will have to move (after a long time with you) I wouldn't recommend anyone mine with you until this is sorted.

Yeah I'm not blaming 12.4, sometimes just disturbing a rig can have affects 

12.4 has made 1 of my 5 rigs less stable than before, I was on a 300+ hour running streak before the upgrade too!

I have to use v8.0 on some rigs due to the power surge issue, I'd like to use SSL as the reported hash rate is better, but v8.0 doesn't support SSL. Any ideas?

coudl be luck of manufacture>? better quality die etc on that card

yep getting 200 from all of mine (see earlier post)

mines a stock 480 its the 8GB "OC" variant though

didn't test -i 4, but -i 6 always output a random card to 0

I'm on a high diff port, does that mean less shares?

R9 Nano's
using -i 4, powlim -47

https://bitcointalk.org/index.php?topic=1679855 seems to indicate more performance could be possible with an 8GB card

Nano's FTW!

Edit: I've seen mention of assessing your GPUs ASIC quality, how do you tell? GPUz? or just the hash rate?

1. Sure do! and I do rename it, just cant see the advantage of having a space int eh source .zip.
2. Yeah this is pretty much my workflow, was wondering if you had anything else, perhaps pulsing the target GPU fan on a keypress?

In some of my rigs with identical cards I've seen the motherboard affect the hashrate...its not always the cards.

Claymore Sir!

Some suggestions for your consideration:

1. Having a directory called "Remote Manager" isn't as smart as "Remote_Manager" or "RemoteManager" from a file-path-in-DOS point of view
2. Could we have some sort of debug option for identifying GPUs? I know the indexing can be iffy, if one GPU is under-performing or outright not working, it may be handy to identify the physical GPU. (at the moment I simply set the fan speed of that GPU to high - perhaps you could follow this lead? or have a better idea?)

thanks for the great miner.

Thanks for the v5 update, much more stable with eye watering speed! finally my 480s are starting to HASH

my 7 card rig is always tricky, are we too ambitious? which mobo you using?

the voltage is only good if you want to overclock, Claymore notes that underclocking isn't possible.

Be careful though, I really upset one of my 6x480 rigs messing with the voltage!

power versus sol/s is always a trade-off! 700W for 310 is great, you may lose 10-20 total.

To make you jealous one of my Nano R9 rigs puts out 360, pulling 650W, although weirdly that is with the PRO 61BTC board only , the PRO 81 boards dont hash as fast! :/

-powlim -50

...powlim can go from +50 to -50, for my Nano's I run -powlim -47 and still get 60 per card, 480s still suck atm though

if you're on windows, copy a shortcut to the .bat file into the shell:startup folder
