After some testing I have to say it is very unstable.
Hi all, need some help with mining.
I have a Powercolor RX480 (ref), which I`m very happy with, mining at ~26-27Mhs, but saw a post somewhere about dual mining with an apu to squeeze a couple more Mhs out.
What I would like to know is how do I go about setting up the dual graphics mining.
Thanks in advance.
Just got a 6x RX 480 unit up and running last night. Thanks to @Madpacket and @poofyhairguy for the suggestions on hardware etc. Had issues getting it to boot properly with more than 4 cards initially. Went through all the usual troubleshooting recommended for the H97 anniversary with risers and 6 cards and wasn't having any luck. Finally it dawned on me that I installed Win10 in legacy mode and not UEFI. Reinstalled with UEFI and everything works perfect.
I started low with underclocking and undervolting and got some bsod's and finally got to stability at 1100/2200 975mv on all 6 cards = 27mh/s on each card. Pulling 950w from the wall according to kill-o-watt (EVGA 1300 G2).
A final interesting note and question. For the first time I got a payout from my pool (dwarfpool) and it not show up in my wallet. Normally its like a minute before it shows up. Its been 6 hours and it still isnt there. The transaction shows up on etherchain so not sure whats going on at this point. The wallet is @ coinbase......anyone else have anything like that happen before?
GJ!
Try lowering voltage and core frequency more. Set GPU clock to 980Mhz and voltage to 900-920 mv. 1020Mhz on core works well too, but some card may need higher voltage.
A conservative estimate would suggests 50c-70c per day based on current difficulty and price.Is this still profitable? I have a 280x sitting idle. Can it make me some money? My electricity is about 8c/kwh I think. Rest of the PC is a core2duo and 6gb ddr2.
So I guess the mining profitability calculator is wrong?A conservative estimate would suggests 50c-70c per day based on current difficulty and price.
I think their estimated hash rates are too high, a full Tahiti can no longer hit 20 Mhash/s and power usage will be very high.So I guess the mining profitability calculator is wrong?
You need to change both. Core and 'memory' voltage.From what I've seen with multiple cards, the 480s (and 470s) have a voltage floor of ~990 mV when mining no matter how low you set the voltage in Wattman, at least according to the gpuz voltage and power sensors.
You could create a new task with task scheduler which runs at system startup. This task would run the batch file with your credentials.The thing is that I have a password to log into my account, but in the case of an unexpected reboot overnight, it won't autologin and run the .bat file. Any creative solutions to this? Most likely won't run into this issue though, but the internet is spotty over there.
any tips for mining remotely?
I'm going to install two cards (deciding if I should go with RX 480s or R9 390s) into my work computer. The power hit from there will be minuscule compared to running at my home.
So far I just have remote viewing software in TeamViewer and ethermine.org has a cool feature that will email me if a machine stops working.

Did you get Chrome Remote Desktop to display the cursor properly? Might want to have that set up, in case Teamviewer doesn't work or does not display AMD Radeon Settings properly, which will happen if you don't have a monitor plugged in.
Second, what if the machine crashes, without a reboot? Your office rig will be left "on" until you are back to physically reboot it - although it won't draw as much power as a rig that's mining, of course. My solution involves using Belkin Wemo Insight switches to remotely control power to the socket, but I'd be interested to hear of others' suggestions.
AMD Radeon Settings is sooo buggy, keeps crashing on me when changing settings. It's a horrible software when trying to use it. Hopefully after tweaking everything I won't have to use it again.
My work computer has had excellent uptime, going for 30 days before, but that was doing nothing lol. I'll cehck out the Belkin item, I've always been interested in something like that. Thanks
