Title: 12.72 Mh/s x 3 7970
Post by: zaico on January 11, 2014, 05:22:13 PM
Hi people! I'm new on mining but I'm sure this can't be right.

I've 3 7970 cards mining Litecoin and that's what it shows on cgminer (BAMT)

Any idea of what it's going on? Must be cgminer mistake or is something dangerous for my cards?

When mining with cgminer you need to specify you want to mine scrypt based coin (like Litecoin). If not, cgminer will try to mine SHA-256 and report much higher hash rate but it won't appear on your pool. To open cgminer to mine Litecoin you need to type: cgminer.exe --scrypt

What does your pool report your hashrate to be?

It was a cgminer mistake. Reboot and everything is back to normaly
