Hi, Claymore!
Will drop you in the near future a new version of your miner ZCash?
Can a little more detail about the stability of version 10?
Thanks  Smiley

I had random reboots on some of my rigs after updating to CZM 9.0/9.1. Try to underclock and undervolt your cards a little (for example I use my 470 4GB with 1200Mhz GPU clock + 1000mV, 1750Mhz memory clock + 950mV, and -5 for voltage offset in WattTool). That solved me the stability issue.

Thanks for the idea, but i have 6xRX480 and i feed with power SEASONIC 1000W Platinum! There should not power be a problem, but I do not know?

1000W is really "narrow" for 6*RX480 cards with stock settings.

I have 6*RX470 with Enermax MAXREVO 1600W in the "unstable" rig. So It can be power problem (I mean the power spikes: you can read about that spikes in the previously posts when v9.0 arrived). I have more rigs with exactly the same hardver and I didn't experience stability issues. Since I did this little underclock/undervolt I also have no problems with this rig. (and the hashrate isn't lower)

So.. just a tip. Try to undervolt and underclock the cards a bit. Especially because 1000W is too short for 6*480.
