Now, it comes to 352. or 304.. As it's 7970, the normal speed shall be 1000+.I don't know what's wrong with my card...
Everything is probably ok with your card, but drivers or the miner itself must be doing something wrong. Any chance you could try Linux?
No, I only use win7. Do you know where can I download AMD driver for linux/UBUNTU? Currently, my card is mining LTC, speed is around 600k. AMD driver version is 12.8 . I think the driver shall be ok...
Actually Catalyst for Ubuntu/Linux is downloaded from the same page with Windows (
http://support.amd.com/en-us/download). But, you cannot use it Windows, I was talking about switching OS itself. But anyway, perhaps you could upgrade Catalyst to 13.12? It should not affect cgminer or your regular usage, but may help with this coin.
This coin is in certain ways more demanding than LTC (for one, it requires much more VRAM), this is why driver flaws (or miner's own, but I am not aware of any for now) have more chance to kick in.
