OK so I have given up using my Terraminer IV for p2pool ... it's just 20% less effective due to unknown reason.
I have pointed my Antminer S3s to my node, no problem, hashing good... Perhaps I will just stick with S3 with p2pool, and Cointerra with traditional pools.
Now I wish to setup merge mining. Can someone please point me to any guide for Namecoin merge mining setup for Windows 7??? Thanks.
Sorry to hear that your Terraminer doesn't work with p2pool and suffers the same kind of performance degradation as the S2 does. I know it's a long shot, but you might want to open a support ticket with them (I KNOW it's a long shot... lol).
Setting up merged-mining is pretty easy. First, download and install the wallet (or you can use the *coind) of a supported coin (NMC, IXC, I0C, DVC, HUC, FSC... any I missed?) and get it all synced up. Second, edit your coin's configuration file. For example, here's my NMC one (changed the user and password):
server=1
daemon=1
listen=1
rpcuser=SOMEUSER
rpcpassword=SOMEPASSWORD
rpcport=7333
rpcallowip=10.0.1.*
Please use different values for user and password - these are just examples. Also, for the rpcallowip, use a range that makes sense for you. My local network is 10.0.1.*. Yours might be 192.168.1.*. Of course, you could always just put in * if you don't want to restrict it.
Now, when you fire up your p2pool node you just add the values. Here's the snippet from my startup showing NMC:
./run_p2pool.py --merged http://SOMEUSER:SOMEPASSWORD@10.0.1.14:7333 ...
10.0.1.14 is the IP address of the machine where you put the NMC wallet.
That's it... you're merge mining BTC and NMC.
Can anyone suggest what is a good additional coin (profitable) to merge with p2pool???
