Does anyone know of any other Diamond pools I can use as a back up that are good?
You can also use a miner that supports stratum. I've been using one to access Danbi's stratum server instead of the http server.
On a side note, when pushpool was dead, the pool luck increased -- it is perhaps because pushpool (getwork) cannot get proper feedback in real time from the wallet that a new block was found on the network. Thus more hashrate is wasted than necessary.
It also seems that Chris&Chris added Diamond support to ccminer, so it should be possible to use that with stratum and nVidia hardware as well. Anyone there tested it? (I don't have nVidia hardware myself)
I am currently using ccminer 1.2 with support for dmd-gr. The settings I run are:
I will try messing around with the stratum settings.
