Whatever improvements Claymore has made, whatever bugs fixed.
My miner use to crash like twice in an hour and sometimes 6 times in an hour.
I even ordered new pci powered risers instead of molex ones. But

Now running stable for more than 2 hours with v9.2! No hardware changes at all.
There is definitely some big fix, atleast for me.

Hashrate has gone stable, no big fluctuations at all on asm mode with dual mining eth+dcr

I am loving this version.
Thank you Claymore once again for such a quick update.
