Guys my miner was working at 38gh fine, now its back down to 30? Any reason why and how can i increase back to 38 again?
Are you using a stratum proxy, by chance? When that happens on mine, it's usually because the proxy is stuck sending diff1 shares for some reason.
After a restart (or three) of the stratum proxy, it will start sending higher diff shares again (starts at diff3 and climbs) and hashrate goes back up. This is just my personal experience with Cubes and stratum proxy connecting to Eligius. Also, purely anecdotal, but I use the "-rt" switch with mining_proxy too. I'm pretty sure I only get diff1 shares w/o it,
but really need to confirm this.
Confirmed, diff1 shares only when I do not use "-rt".
