Yup! just got it up and running on my 1 4-RX 470 rig. Running nicely at 40-44 S/s per card (over-clocked & under-volted). This is WAY up from the 13 I was getting using NHM and while certainly not near the 100 that was initially hoped for, that's a 3x increase that I will gladly pay the 2.5% fee for!
Another thing is that this takes WAY less power than mining ETH. My full 4-card system only pulls 400-450W running this (and nothing else)... it was using 630-650 with CDM solo mining ETH, so about a 35% reduction is a nice additional bonus!
Waiting a bit to start up NHM for CPU mining. Hopefully there won't be any conflict. When I ran NHM CPU yesterday concurrently with CDM ETH, it completely hosed my ETH returns.
Just tried to run NHM CPU on ZEC concurrently with Claymore GPU ZEC and had bad results. Firstly, the hashrate on Claymore dropped by about 25% from 40/card to 30/card. That alone won't do since Im only getting 23 S/s from my 6800k CPU... so that would be a net loss of 17 S/s. But, even worse, after about 5 minutes, it crashed my system. Rebooted, reset GPU settings in Afterburner, launched Claymore again and crash within 1 minute without anything else running. Reboot again and now Claymore running stable for close to 20 minutes, but Im disappointed about not being able to run both at same time.
I think this is a NHM issue more than Claymore ZEC since as I mentioned, NHM CPU also hosed my CDM ETH miner yesterday while trying to run both. As it stands I am more than double my sol-rate on this rig vs yesterday but it sucks to have to leave the CPU idle when it could be pulling 23 S/s. Also, this equates to a double suck (unless somehow rectified) as I just ordered a 4790K CPU yesterday for my 2nd rig.
