I'm new to this mining thing, but i didn't think it was possible to mine Equihash (zcash, zen, zclassic) with this miner? If incorrect I could use some help with the bat file, because I cant get it to work.

It is possible......... use ......... ccminer.exe -a equihash ..........
Although the hashrate for this algo is less in ccminer....compared to alternative miners available with 2% devfee.

Consider excavator, nicehash has done a really good job with this miner after all that dev work. Not sure if you can mine anywhere but nicehash to be honest, but there is no fee as far as i'm aware and factoring in fees I see about the same speed.

multiplier is just a setting for the com between the pool and the miner.. nothing related to coin diff

I am a pool operator, and found that there is difficulty multiplier set for different algos in ccminer, may I know what is the reason behind that?

weird question from a pool operator.
a multiplier is applied to stratum diff and may be different from coin to coin.
it's been like that for ages.
usually, a multiplier is set for a hashing algo when the first stratum implementation is made.
it's just a way to allow much easier shares for slow miners (compared to net hashrate).

The difficulty showing in the coin daemon(i.e., MaxCoin- Keccak, Digibyte - Scrypt) isn't multiplied. If we apply multiplier there, the difficulty showing in stratum will not be the same as what reporting from the daemon. So we haven't set the multiplier in the stratum pool and that works fine in sgminer. But for ccminer, there is a default multiplier for Keccak. Our pool give 1024 pool difficulty to the miner and ccminer will submit all shares which has difficulty >8. And so the reject rate showing is >99%. If I set multiplier = 128 in the pool for Keccak which is the same as ccminer, this will cause sgminer not submitting shares as it is too difficult for them. Moreover, it may also cause the pool difficulty (~128000) will be larger than network difficulty (~1000).

Here is a feature request, please consider adding a ping display to the current pool. Either by running a ping periodically or how long it takes for queries back and forth. This would be very helpful for diagnosing the health of the pool you're connected to.

You can access ping through ccminer api

sigh.... if you want to mine an old algo with an old gpu, so use an old version... they are still on github

Try turning your overclock down

that didn't help
it crashes sooner or later

Did you enter your wallet address or did you leave it as shown above? "<>" needs to be replaced with your Zcash wallet address in order for it to work.

sure, I entered my wallet address
