So I have sold off the last of my S5's due to the release of s7s and a very fast declining return. After a year of mining I have to say its an interesting endeavor that can consume a lot of capital but the return is decent if you don't pay for power.

That being said I have decided to invest in an ETH miner and sourced the following parts.

New
http://btc-priceimg.herokuapp.com/advimg?price=61.9CAD&currency=BTC&color=00f - MOB: ASRock 970 Extreme3, AM3+ (plus), AMD. Probably a bit of overkill but the price was fair.
http://btc-priceimg.herokuapp.com/advimg?price=23.7CAD&currency=BTC&color=00f - HDD: F5 2.5" SATA 32GB Kingfast MLC SSD. My thoughts are to run GenEthOS on the SSD.
http://btc-priceimg.herokuapp.com/advimg?price=23.0CAD&currency=BTC&color=00f - Riser: 4x USB 3.0 PCI-E PCI Express 1x to 16x Extender Riser Adapter
http://btc-priceimg.herokuapp.com/advimg?price=45.2CAD&currency=BTC&color=00f - RAM: Corsair Vengenace DDR3 1866MHZ 8gb (2x4gb). Again probably overkill but the price seemed good and I wont have to worry about memory thereafter.

Used
http://btc-priceimg.herokuapp.com/advimg?price=98.6CAD&currency=BTC&color=00f - PSU: 1200 watt EVGA Supernova P2 Gold. left over from S5 operations.
http://btc-priceimg.herokuapp.com/advimg?price=35.37CAD&currency=BTC&color=00f - CPU: AMD Athlon II X3 405e 2.3 GHz Triple-Core CPU Processor Socket AM3
http://btc-priceimg.herokuapp.com/advimg?price=120.0CAD&currency=BTC&color=00f - GPU: Asus R9 290x 4gb

Total cost of inital package was about http://btc-priceimg.herokuapp.com/advimg?price=407.0CAD&currency=BTC&color=00f. I plan to source another 3x 290s in the http://btc-priceimg.herokuapp.com/advimg?price=120.0CAD&currency=BTC&color=00f range over the next month. From there my assumption is I should be mining about 6ETH/Week per 290x based on this calculator (https://badmofo.github.io/ethereum-mining-calculator/ (https://badmofo.github.io/ethereum-mining-calculator/)).

Total cost recovery on the current system (1x 290x) at current rates is currently about 5 weeks. based on the Shapeshift Instant Rate 1 BTC = 54.02439024 ETH.

Thoughts on my setup? I still need a case, I know.

Just for clarification, Eth's hashing algorithm is called Dagger-Hashimoto and not x11. Therefore Eth has nothing to do with x11.

X11 is ASIC territory just like Scrypt and SHA256.

Clearly I got some learning to do :) Edits made.

32gb ssd is too small.

return it and get a bigger one.


do you live in usa?

this would be better choice

0.16 bitcoin for GPU: Asus R9 290x 4gb. That is just $100 for the 290x. That is very cheap. Get as many as you can.

well that is a used one.

Really cheap parts, I wish I could get my hands on 100$ 290Xs. and also the PSU is a really good deal. Overall a good and balanced system that would return its cost quickly.

R9 290 will make you only like 1.5ETH per week.

Can someone direct me to a troubleshoot for AMDGPU-PRO on the 280x? I am running Ubuntu 16.04 LTS but after following the guide on http://support.amd.com/en-us/kb-articles/Pages/AMDGPU-PRO-Install.aspx I get a blinky desktop and have to tty1 my way out by removing AMDGPU-PRO. I can't seem to find a fix for this but I found similar issues online from people with nvidia cards. (That fix was available through an update)

Thoughts?

The best card is AMD RX 480 now.

280X is not supported by that driver atm.  I have to use fglrx for my 280s.
Thats why I had to reshuffle the cards on my rigs. Couldnt have those rx470s and 280xes in the same rig.
BTW you should consider mining something else than ETH with 280X, since they suffer from the TLB syndrome now..
They are good at XMR still...

Shift to Ubuntu or XUbuntu 14.04 for now, it still supports fglrx where 16.04 does not, and a lot of the miner packages are available pre-compiled for it, if you're using pre-RX series AMD cards.

I'm not sure if fglrx was updated for RX 480/470 support.
