Since Fed-Ex shows that the two Open Compute servers that I have ordered Friday will be dropped off tomorrow I'm going to start this build thread tonight.
I’m posting it in the new “Cryptocurrency Mining and Markets” forum not the “DIY Server and Workstation Builds” forum or the “Great Deals: Potential Deal: 2 x Dual 2011 nodes @$199, Quanta Openrack” because it is not a typical server or workstation build and its more suited here because that it is for one specific task…..cpu mining.
I was actually planning the generic open case 6 gpu miner. With the limited availability of Amd Rx 580 and Rx570 gpu’s and the cost I would have been looking at I decided to try something different.
If I had decided to still go the gpu route this is a price breakdown of a 6 gpu miner, prices via Newegg or Ebay new unless noted.
6 x Rx570’s [$200.00 each] $1200.00
1x Cheap case [ Cheapest on on ebay, basically just an aluminum angle frame riveted together with wood cross bars to mount the motherboard] $75.00
1x EGVA 1300w G2 power supply $259.99
6x PCI-e risers $50.00
1x Power switch $5.00
1x 4 gig DDr3 Ram [used] $12.00
1x Biostar TB85 socket 1150 mb [Already purchased] $79.00
1x Intel Celeron G1840 LGA1150 cpu w/ fan $45.00
1x 16gig SSD [used] $15.00
--------------------------
total $1749.99
Shipping or taxes not included nor is an operating system included in the price. Also it is assumed a monitor, keyboard and mouse are already on hand for the 6 gpu rig and the OC servers.
The RX570’s are super hard to get now, also the mining motherboard I have is no longer being manufactured and the prices are now way over $100.00 now.
There are newer mining motherboards based on newer chipsets but are more expensive, so it would be real easy to end up spending a couple hundred more than what I listed or a couple of hundred dollars less if you can find better deals or more used parts.
Modded Rx570 gpu’s would probably mine Monero ~625 H/s stable each so about ~3700 H/s .
Thats about 2.12 H/s per dollar.
The prices to build a dedicated GPU miner plus the tinkering/moding, oh and modding a gpu bios takes a lot of trial and error and lots of testing and even then the stability is a lot of times very hard to attain even with identical video cards.
So that caused me to rethink things and after I found a 250v 20A electrical socket in a almost idea place I immediately thought of those Open Compute servers listed on Ebay, Wiwynn and Quanta.
The main differences is that the Wiwynn in new in the box with everything except cpu’s, ram and hard drive and the Quanta is used, about $50.00 cheaper, and takes V2 cpu’s already, has a newer bios available and I think lets you run Windows 8 or 10 but its seems to be a bit of a hit or miss with what they come with.
I chose the Wiwynn mainly because its brand new, I have had great luck being given used motherboards but really horrible luck with buying used boards.
And if I want to try to get a V2 or even an ES cpu running on it I feel pretty comfortable that I could mod the motherboard bios to allow that.
So cost breakdown, very preliminary because I will try things and once I am happy with what ever combo I end up with [ ram, cpu’s ect] i’ll post a more accurate cost breakdown.
-------------------------------------------------------------------------------------------
EDIT: Final prices.
2x Wiwynn open compute server $380.00 NEW
4x E5-2660 V1 cpu’s $207.92 (best price found but the seller only had 4) USED
4x E5-2660 V1 cpu’s $230.80 USED
8 Gb of DDR 8500 8x1 Gb sticks $17.50 USED
4x used hard drives that I already had $00.00 USED
1x New HP PDU $10.00 NEW
2x Power cords to reach unused 250V a/c outlet $20.00 NEW
*not including shipping
Total $866.22 gives 3480 H/s
----------------------------------------------------------------------------------------------
I plan on running a “Master Node” with the video card, usb card, keyboard and monitor with probibly more ram than the headless nodes until I come up with a final setup that I will run in all nodes. I expect to be able to just install Ubuntu server using the Master node and just move them over to the other nodes.
Two nodes of E5-2660’s should have a hash rate of ~1680 H/s
Two nodes of E5-2650’s should hash about ~ 1500 h/s
About ~3180 H/s with 4x 2660 and 4x 2650 cpu’s, but I'm not %100 set on the 4x 2650’s in the second node.
So with the above number its about 3.3 H/s per dollar with two OC servers running cpu’s only vs 2.12 H/s per dollar on the 6 gpu build.
Will be fun!!
Oh and will start to post pics tomorrow.
