Moved from bitparking to 50btc and now I'm constantly getting a lot of Rejected shares at Diff8  Huh
Does anybody have fixed issue like this?

Edit: FW both 20130703 and 20130723

Change your diff to 64 on 50btc under settings for miner is probs why you getting too many rejected shares.

Thanks. Did it already. Looks like it helps.
No, that's not actually making it better unless there is an actual problem with the pool - which would mean don't use the pool.
Going from 8diff to 64diff simply means your Reject share variance increases.
Coz on average you find 1/8 of the rejected shares ... but they are worth 8 times as much each.
That's right. It's not a solution.

If 50BTC is using a large coinbase, you might have been getting struck by the excessive CPU usage limitation in older firmware just like p2pool was. This might manifest as duplicate shares and only show up as rejects at your pool. Most of the recent updates were created to address precisely that problem. Try my latest firmware.

Thank you, ckolivas. I'll consider to move to the new firmware as it gets mature. I just read the feedback that new FW are affected by the lower hashrate than 0703.
