I have a very strange problem which is probably related to being a n00b, so forgive me in advance.

There are 2x 7970 Sapphire Vapor-X in one rig, both have identical overclocks and Crossfire is disabled (but cable in place). However one card hashes at twice the speed of the other.



CCC version 13.1 plus most recent APP version (2.8 iirc).

Can some advise what I am doing wrong please, it is driving me insane.

Thanks

Hi,

First off, great job with the client, it is very good.

I have one small problem, which is probably due to my lack of knowledge. I noticed that my client is showing my balance is around 0.4BTC less than what is shown on blockchain.info, all transactions are fully confirmed.

Is there are way to fully resync the client with the blockchain without losing my wallet?

Thanks.

I have mined solo until now, but want to join pool for more regular payouts. But which one gives the best return for my 6GH/s work rate?

Thanks.
