stratum+tcp://eac.suprnova.cc:3515 Nicehash: 3516 ASIC: 3514

I am wondering what Nicehash: 3516 ASIC: 3514 means in this file.

ICO? Not even once.

Their different ports probably have different difficulties associated with them.

ASICs - which are super good at what they do - get much bigger chunks of work to solve (higher difficulty) while CPUs and GPUs with the nicehash miner get smaller chunks of work to solve.

Too high difficulty means your miner will take a long time to solve shares which means you might not solve the work you've given before someone else finds a block so your work is pointless.

On the other hand, too low difficulty causes your miner to get small chunks of work which are too easy so your miner will bombard the pool with a bunch of solved shares, effectively DoS-ing it.

Not your keys, not your coins!

I have my asics mostly pointed to bitcoin and sometimes other things.  This was in a Earthcoin script I wanted to point a gridseed orb with no fan (hence no sha256) at bc I'm still trying to find good scrypt coins to mine. 

I am using this successfully:

cgminer.exe --scrypt -o stratum+tcp://eac.suprnova.cc:3515 -u name p pw --gridseed-options=baud=115200,freq=800,chips=5 --hotplug 5

do you (or anyone) suggest I change anything?

As bathrobehero said, two different ports to the the same pool. The first one which you are using is probably a vardiff, which means the stratum server will adjust the minimum difficulty it requests from your miner based on an expected timespan. For example if the stratum wants to get a share every 30s, it will over time adjust your difficulty so that your miner with it's given hashrate is able so submit a share around every 30s.

On the other hand if you rent miners from nicehash which start at a minimum of 0.1Gh/s but often go as high as 10Gh/s or even more you need a stratum port with a fixed (very high) difficulty, elsewise if the nicehash miners would start with the same diff as your miner they would try to send hundreds or thousands of low diff shares within the first 30s and overhelm the pool completely., therefor nicehash ports have a fixed high diff like 32768 or 16384.
So if you would point your gridseed toward the nicehash port, you would probably never be able to submit a single share (or it would take a very long time).

That said, your command line above looks fine and like what you should use on that pool.
Never try to use a port labelled with "nicehash" if you have less than 500Mh/s under your mousepointer.
BTW: Your gridseed is an asic miner, so that fits too ;-)
