Hello Fellow Miner,

I am using ethminer for Nvidia Cards as the hashrate is same as claymore. the cards are 6 GB. Rigs Uptime was 9 hrs.

But using claymore I am getting around 2-3 % stale shares in windows 7.

(stats from pool ethermine.org using the nearest server)

The internet connection is perfectly fine and same for both the above rigs.

any ideas why so?

Should I shift to claymore or any other miner ? or is it just random?

hi, for how log did you mine ?
For one thing I know ethminer have 2 stratum module, and one is very inefficient.
You may have a version that use this old stratum module.
From what I remember about claymore's, he re-write the stratum module and it look freakin optimal.
To be sure, try another miner (genoil for example is supposed to have a stratum module quite optimal).

good luck
