Building Cheap Miners : My "Secret"

[javorcro]

Hey guys,

I did some cost vs. hash power analysis of all my system types...

4x 1060
3x 1070
3x 1070 Ti
3x 1080

I do have one system with a single 1080 Ti that I'll throw in the mix later.

This is JUST *cost* per "work unit" (whatever that is per algo) -- not factoring in power cost.

Basically... the 1060 systems clean house EVEN when I figure in the cost of the computer itself in nearly every category in terms of up-front costs per work unit.

And a surprise... the 1070 Ti is a *better* value than the regular 1070 at current pricing on almost all algos (except Equihash). I listed the price I used per card which is the best I can find at this time per card type.

Now... I didn't agonize over optimized every card. I simply gave them all the same 85% power rate and some basic overclocking... I did this for my reference mostly as I wanted to be sure building with 1060s is what I wanted to keep doing (and it is).

thanks for putting this together

[sundownz]

Glad I could be of some help sharing my info =)

----------

Also... another tip on the HP Z400 machines... if you are upgrading to the X5660 CPUs like I am (for mining CryptoNite) make sure you have flashed the BIOS first. Some of the systems ship with pretty old BIOS versions and will NOT recognize the newer CPUs.

[jeswin]

Great, keep sharing such positive information

** Package of XEON X5660 CPUs. I do CPU mining on these and these chips are CHEAP on E-Bay and 3x faster than the one that comes in them & also draw less power.

This has paid off nicely... so far have mined 600k INTENSE coins (CryptoNight) on my CPUs alone.

Current value ~$3400+ USD.

Are you using hardware wallet or?

I am using the QT-Wallet for Intense.

** Here is the ATX to EPS adapter that I spoke about in the OP.


** Goes in like so.

Hey sundownz could you provide a link for this adapter please.
Cant seem to find it.

Thanks again for the write up Im trying to upgrade the 475watt into 620watt thatI have sitting on the bench.

Thanks.

You actually have to make it -- here are the two parts:

https://www.amazon.com/gp/product/B0007RXDDM/ref=oh_aui_detailpage_o03_s01?ie=UTF8&psc=1

And here are the instructions on making it (I found this on Google when I was starting):

This is the MOLEX tool I use:

https://www.amazon.com/gp/product/B004EGF9Q6/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

You may be able to use a cheaper one... but I've done dozens of the adapters so I got a nice one.

[greyday]

Apologies if this was already said, but those evga refurb prices aren't that great, if you're not picky about brand and are a little patient you can find the same or better at Amazon or Newegg...

At the time that I got them they were a much better deal -- they have since marked them up alot.

The full size / dual fan 1070s were $319.99 when I made the OP.

Oooh, nice! Good snag on your part.

[Branko]

Can any of those servers accept 3 cards inside the case, HP800 series for example?

Or some Dell?

[jeswin]

Informative... Keep sharing such ideas again

i am interested to HP 8000 elite tower also, it suppose to handle thre GPUs.

specs Core 2 due
RAM 4 G.

need to try it.

* A completed adapter (left) and the two parts linked above (right)  to make another one.


* Showing the two wires I  remove from the motherboard side of the plug with the MOLEX tool.


* I just yank the wires out of the other side of the plug as we don't need them.


* Showing the other part of the adapter taken apart with the MOLEX tool.


* Close up of the pins.


* You will want to bend the "wings"  back out carefully.


* Then insert them in the proper places in the motherboard side of the plug.


* And all done!

Got my third rack 100% completed and wires neatened up:

haha, that one lonely DL580 G7 up there. Did you get 12 cards working on it? Just today I ran some pricing figures for it in another thread when I was arguing with some guy who wanted people to pay $29999 for 24x 1080-TI system.



24x 1080-TI $710/each (https://www.newegg.com/Product/Product.aspx?Item=N82E16814126188)
2x DL580 G7 $300/each (https://www.ebay.com/itm/HP-Proliant-DL580-G7-4U-E7-4830-2-13GHz-16-Core-64GB-RAM-2-x-72GB-P410i-W-RAILS/282660829215?epid=129658107&hash=item41cfe5f81f:g:rWIAAOSwufpZwV7I)
2x DL580 G7 IO Board $66/each (https://www.ebay.com/itm/HP-DL580-G7-PCI-E-Riser-Card-588137-B21/172984027345?hash=item2846a6c8d1:g:BaUAAOSwCU1YwEqh)
24x Riser cables $5/each (https://www.newegg.com/Product/Product.aspx?Item=9SIA72562E8994&cm_re=pci-e_extender_mining-_-17Z-00AT-00003-_-Product)
6x additional 1200W PSU $40/each  (can only run 4 1080TI per 1200W) - (https://www.ebay.com/itm/HP-Proliant-G6-G7-Power-Supply-1200W-490594-001-500172-B21-438203-001-HSTNS-PL11/172979235302?hash=item28465da9e6:g:mD4AAOSw9KhaCkkb)
6x PSU breakout boards $17/each (https://www.ebay.com/i/182897146692?rt=nc) -- includes PCIE cables.. If the 1080TI needs 8 pin (I don't know because I've never owned one), it's also possible to get the PSU breakout board in 8x 8 pin instead of 10x 6pin... For roughly the same price.

Total cost: $18234 for 24x 1080-TI including systems -- cost per GPU = $759/GPU.. Cost per PCI-E slot is $49/each. It's probably possible to get that a little lower per pcie slot.

Those expansion boards are pretty cheap


Edit: Wait, is that DL580 G7? On closer inspection just looks like a mid tower. I want to see that DL580 up there with your other systems

This is the one I got -- just one of them right now.

So far just been using the CPUs but I do plan to run some smaller GPUs from it (8 pcs) at the moment -- then experiment with more cards later =)

It sits on my "work bench" table so it's not in the pic.

All of my other stuff is standard mid-tower (mostly HP Z400).

Did you measure the power consumption of this one by any chance — mining cryptonight? Been thinking about trying one of these, but scared that they'll eat like 300W or something.
