Perhaps a smart contract for it from one of the templates on github.  One for Ethereum, one for Expanse and one for SHIFT.  That should bring in some dev cash.

Of course. Sometimes I forget where all the mining is actually useful for


Of course. Or use a different pool. Moar money for you!

what is better for nvidia, launching with -U or -G?

Yes, after not being successful at getting a working stratum connection with genoil ethminer by itself to Dwarfpool, I dropped back to genoil ethminer in regular getwork (farm) mining mode to an eth-proxy and ran a network sniffer on the inbound and outbound traffic on the proxy host machine.

What are you using for your AMD cards? I have been using Claymore 4.3 seems to be ok. Do you suggest anything different? My 6 380x cards are pulling about 128.5 on average. (21.4 percard)

With genoil ethminer Im pulling 27.x MHs per Sapphire R9 280X Vapor-X under Ubuntu 14.04 with the proprietary AMD driver set at 15.something.  Was running the stock ethminer that came with the ethereum package. Mining speed is roughly a 7 MHs increase on average. Its also farm mining against an eth-proxy running on a different server setup for Expanse on Dwarfpool.  I had hoped to use genoil's ethminer stratum feature to hit it directly (sans proxy) so that I could set up a little profit switching with Ethereum and SHIFT but to no avail.  Just have to have a little more patience

My run script is:

#!/bin/bash

export GPU_FORCE_64BIT_PTR=0
export GPU_MAX_HEAP_SIZE=100
export GPU_USE_SYNC_OBJECTS=1
export GPU_MAX_ALLOC_PERCENT=100

ethminer -R ~/.ethash-exp -E old --farm-recheck 300 -G -F http://192.168.1.5:8080/rig3 --cl-extragpu-mem 16 --cl-local-work 256 --cl-global-work 16384


Haven't checked out Claymore yet, but I will now.

NOTE:  Vapor-X cards suck for mining which is why I use them on my test rig. I would expect that a better version of the R9 280X or a newer generation card will probably have better results.

SAME HERE--

I was getting 22MH/s a month ago.  The rig has become slower since.  OC sits at 1100/1500, stock power, no undervolting.  However, I am not using Genoil's miner on the AMD rig.       --scryptr

Generally, your rig will get slower as the difficulty rises and the DAG gets bigger, regardless the mining software you use.  An optimized CL kernel will only get you so far after all.  The best variable to adjust your overall speed just from my experience is the Farm recheck time.  get a good balance there with your other variables and it will give a smooth consistent mining speed rather than speeds that tend to fluctuate
.   Also keep in mind that Im mining the snot out of Expanse at 27 MHs (much lower difficulty) for now as the difficulty of Ethereum which I was getting about 20 MHs per card until it eventually grew above a difficulty that I could remain profitable at.  SHIFT for example with such a currently low difficulty would give a high mining rate I think.

UPDATE:  Gave Claymore a spin and it is fairly elegant.  I didnt really see the speed increase. In fact it was a little slower.  But that may be configuration settings and such also.  Regardless, I don't like proprietary binaries running on my rigs so I gave it the ax and switched back to genoil's ethminer.

Expanse unfortunately isnt quite up there with Ethereum as far as price goes. If you can mine enough EXP in a day vs 1 ETH in a day you could be at least be even.  Honestly Ive only roughly worked out the math. Im just a mining freak that doesn't like my rigs to be unproductive.  And all my rigs run 24/7 as well.
