Thanks for all the input.  I checked through all of them but since the recent spike in interest crypto, everything is out of whack right now.  I have decided short term to focus on running ethereum nodes to get gain experience in anticipation of POS. Also, in the future, maybe SOMN (seems to be having issues) or something like SOMN.  I will also try to set up some file sharing services to squeeze out every last bit from my rigs.  Thanks again everyone.

Are there any coins around that are CPU mining only?

I think it's because Decred is out of favor/on it's way out.

If dual mining like this was possible, I don't think we would have seen the global hash rate drop so much.

It's taken me two or three days, but I finally have gotten this to work.  I could not get blat to work (error about sender name), so I used Swithmail instead.  I think it had something to do with security and maybe I needed Stunnel also.

Thanks for posting this though, it helped me over some hurdles. 

Try commenting out the line below:

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

Do you have this line in your start.bash file?
Export GPU_FORCE_64BIT_PTR=0
If so, try disabling it with a #.

- How would I run the miner at system startup as user, inside screen ?

Depends on which distro you are using but add the application to the "Startup Applications" with the following command:

gnome-terminal -e "'\home\path\to\directory\start.sh'"

Note: there are single quotes inbetween the double quotes in case there are spaces in the directory path.

gnome-terminal or mate-terminal or terminal vary based on the distro you are using.

Start with BIOS settings on motherboard.  You usually have three options after a power loss event:  Shut Off, Turn On, Return to Previous State

Next would depend on your operating system.  For Windows, add program to startup folder.  For Linux, add program to Startup Applications.

Follow the directions provided on the pool website.  If you are just starting, I would get some equipment (maybe just one video card) and get that up and running. 

Nice job on this.  Where did you get those rails for the structure?

I'm definitely not an expert, but I got it running by:

1.Loading 14.04
2.After loading going to "Software Updater" and installing all updates.
3.After updates are installed, go to "Software Center" and search for "AMD". Select and install fglrx-amdccle.

There were probably some reboots in there, but I had tried so many times before that I am not sure.

Here is my Linux start.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
     export GPU_SINGLE_ALLOC_PERCENT=100

I also just got it working using Linux mint 17.03 with a similar procedure.  Linux mint is better looking than 14.04.

Now, I just need to figure out how to get more than 3 cards going on a motherboard and how to set these up 'headless'

Does this miner support cyrptonight algo?

I am getting ~550 H/s with the dev fee turned on.  That's the machine reporting, not at the pool site.

Mining question.  What are everyone's expectations on being able to mine this when released. Are there any coins in particular that might see a drop in overall difficulty/nethash? It seems to me that despite all the new and old coins, there never seems to be a shortage of hash power.

I mined this from the first block until the last block with 2 gpus (280x and 290).  I ended up with 901 ICB.  Anybody else want to post their results, just for comparison?

I am speculating that since POW is ending, hash will be pointed to a multipool.  This will provide a supply of "buyers".  Increase in price is due to people buying, expecting to sell into the multipool buys.

I was having the same issues with the wallet. I just closed and reopened it, and now it is syncing.  I know you probably have tried that already.

Regarding the multipool.  There are not a lot of NIST5 coins available, so how rewarding would the multipool actually be? Is the intent to switch algos?

Wallet wont sync.  It is stuck on 297 and has the error message "Invalid checkpoint found, Displayed transactions may not be correct. You may need to upgrade or notify developers"

Mining does seem to be working on pool.mn

How can they POW mine 30 mil. coin, when some of the blocks are POS? Shouldn't all of the 20000 blocks be for POW only?
