I am getting a reported hashrate 6% higher (we will see how it actually plays out over time) which completely covers the 2% software fee. PLUS I am now mining a little decred coin on the side on the same 390x GPU, which hopefully will cut into the power costs (I estimate 50%!). So 4% extra plus some other coin for free power? Hell yeah! Here is a full analysis of mining profitability, I am doing decred at -40 and it is not effecting my reported Eth hashrate really (like 0.5%):
Which driver version are you using? I don't wanna go back to 15.12 lol.
I couldn't get 15.12 to install so I am using 16.1.1.
Okay, good to see the increase even with the newer driver. I'll have to give this a shot when I go home. Thanks for the heads up!
I did sent 10 ETH to it.
I need to read up on DAO and the voting and what not.
Is anyone considering the DAO? I was thinking about maybe getting 1000 shares or so:

How does this actually work? And what is the benefit?
Do you actually get something like a dividend every once in a while? Or is it just like buying a stock that can appreciate?

Ok, I answered my own question. There isn't much of a difference between ether-proxy and qtminer, except qtminer will try to submit rejected shares while ether-proxy won't (as a speed choice). I can't tell a difference between them in mining as far as hash-rate
Mining software that DOES make a difference to me is the claymore miner:

One other thing I found out is this Claymore miner LOVES overclocking. Loves it. So if you have a really highly clocked GPU I would at least try it.
I also got my other machine up and running- 280x at 1050 on Ubuntu 14.14. Uses 270 watts which is nice, but my hashrate seems low right now- around 17. I was using qtminer at first to test, I will probably switch that one to the Claymore miner soon to try and get a better hash rate.
Can you report back in a few days and see if you actually notice a difference?
also do you have any power measurement differences when mining both coins vs just ethereum?
For me the amount of downtime and tweaking to switch over 8 miners would probably lose me more money the 1-2% performance improvements (unless it really is closer to 5%). I think the real value here is in mining the Decred coin at the same time but if it increases power costs by 15-20% maybe not.

Okay tried out that Claymore miner linked to.
It says I'm getting 62MHs ether and 1500MHs on DCR, with 2x290 at 1100/1250. This is at DCR -50.
What driver version are you using? Also, is that a Windows or Linux client?
I have a spare Sapphire Dual-X 7970 that I tried 2 days ago. @ 1125mhz on stock voltage of 1.175V, the best I got out of it was 18.5-20MH/sec, even though it benchmarked 22-24MH/sec (ethminer -G -M). However, while actually mining, it was much closer to 18.5-20MH/sec, substantially less than my Hawaii cards which are doing 30-31.5MH/sec with the same command lines. I actually thought Tahiti is much better than that but it isn't. On stock voltage, with an i7 6700K @ 800mhz, total power usage was 226W with a 1000W SeaSonic Platinum.
I am curious to know how well GP104 will mine against Polaris 10 and Hawaii.
Some R9 390X cards are selling for almost the same price as the R9 390s.
Power usage is up to about 680w from 550w.
According to this calculator I am making enough DCR to offset a lot of the power costs. However, my VRM temps jumped almost 20C so I don't think I'm going to keep running it.

Using 16.2 on Windows 10.
Yeah I might not keep it up too long either, maybe just a month for fun. If you look at the effective rate for me it was WAY lower- 500 vs 250! Decred might not make sense, I will judge the miner on average Eth rate over the next couple of days.
I tried the Claymore miner...definitely better speeds on ETH but it draws too much power and gets WAY too hot to dual mine decred. Not the GPU but the on-card memory and VRMs.
Once I factor in the extra power usage, 2% fee, etc. it looks like it'd be an extra $5 monthly MAYBE if I actually get the decred predicted (which didn't seem to be happening when I tried a few pools).
Also, with so many people mining decred now the difficulty is really rising and very soon it will not be profitable at all unless the price moves beyond $1.50.

Current supply checks on Newegg show that AMD continues to send new R9 390 cards.
MSI Radeon R9 390 DirectX 12 R9 390 GAMING = 300 new units available
PowerColor PCS+ Radeon R9 390 = 300 new units available
Looks like someone at AMD did take notice as new shipments of 200-300 units are coming in as soon as the previous shipment sells out. This also means the network rate will continue rising as every single R9 390 shipped sells out. With so many new R9 390 cards arriving, I am not even sure Polaris 10 will launch in retail around Computex May 31-June 4th. Just 600 PowerColor PCS+ and MSI Gaming 390s have to sell in a just a month if Polaris 10 is going retail June 4th unless AMD is going to be major discounts on remaining inventory.
