Another deal I caught... my 3x VEGA-64 system is drawing more than I'd like even on the 850-watt supplies.

Wanting to keep the load ~85% or less so I bought one 1200-watt supply... killer deal $191.99 for Rosewill Quark 1200!

https://www.amazon.com/gp/product/B00VS8728G/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

So... in the future I will only buy VEGA-56 as power draw is ~50 watts less each for about the same Cryptonight performance. Those will run on my 850-watt supplies.

From what I've heard a properly tuned Vega should draw ~ 150W on cryptonight. Don't have any Vega's myself though, but don't have any reasons to doubt the people I've heard it from. 3 of those shouldn't draw much more than 500W.

Hi there,
is anyone here running 4 vegas on a dell T5500. I wouls like to be sure it works somehow.

On mine It runs fine with three, but fourth card gives me nightmares. Artifacts and crash on miner start ( it's not a card in particular, I switched them). Even if fourth card is plugged but not in the mining config, it crashes.

I thought about crossfire&ULPS disabling, but It didn't help. Changing miner soft does not change anything either.

Any ideas?

Is there physical space inside that box for all those cards, or you use risers?

I am diversifying my farm a little... due to my interest in Cryptonight I bought some RX570/580 cards on Black Friday & Cyber Monday ($229 or less per card)... as well as 3x VEGA64 cards (these are beasts... landed three for $549.99 each).

And last night I found a deal I couldn't pass up on the higher-end EVGA 1070 Ti FTW2 model for $469 each... got 9 of those on order. May have been a mis-print as B&H photo changed it to $499.99 this morning:

https://www.bhphotovideo.com/c/product/1369702-REG/evga_08g_p4_6775_kr_geforce_gtx_1070_ti.html

-----

I also found several deals on 850-watt PSUs so I will be using a lot of those... which will be great for the 1070Ti FTW cards (each needs 2x 8-pin) since the 850s have 6x PCI-E plugs and I will run three per system.

https://www.newegg.com/Product/Product.aspx?Item=N82E16817182324
** These were $89.99 on Cyber Monday

https://www.newegg.com/Product/Product.aspx?Item=9SIA0723W13838
** Also caught a random deal on these for $89.99 a few weeks ago

-----

So I am continuing my philosophy of only buying stuff at a good deal =)

Double checked... low to mid 500s just sitting there then about 800-watts with all 40-cores running.

The CPUs are TDP of around 130W (520W max). I wonder if it's those high RPM fans? Seems like there's something eating up 300W.

** 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.

So... I figured out... don't waste time using any miner other than XMRig.

I went from ~170 to ~230 per X5660 switching up CPU miners (just using the regular "cpuminer" program before).

Still hanging out on Intense... value not as high as my last post but I think it has huge potential.

-----

Only issue is getting it to load on system boot -- as it needs to be ran as admin for "huge pages" to work (without huge pages it's no faster).

So... you need to use Windows Task scheduler... make a task that starts at "USER LOGIN" (NOT System boot)... and tell it to "run with highest priveledge" -- and it will start correctly. Just putting a normal shortcut in the startup folder doesn't work.

I imagine there has to be some way to get the "idle" power draw down -- but I don't know it. At least not yet, haha.

I can't even think of anything that would draw 500W idle there. Cheesy

Maybe some extra controllers enabled that you could disable or remove? Maybe some crazy high-rpm fans? Most of the server boards I've seen don't have that many power-saving options in their BIOSes. Maybe some kind of C1E option there to make the CPUs drop the multiplier and voltage while idling, but then again, if you're cpu mining with this one, then it won't save much.

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

So far just been using the CPUs

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.

It is a power hog -- running all 40 CPU cores on Cryptonite the system draws nearly 800 watts (IIRC... I'll double check when I get to the shop in a few).

Although, it draws quite a bit just sitting there at idle... there may be ways to optimize that which I haven't found yet.

Holy crap, that's a lot more than I could even imagine. Cheesy

It's still profitable I guess with the current prices, but for those with limited power (myself included) that's probably a no go. Thanks for the info!

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).

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

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/B000FL60AI/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

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):

https://plus.google.com/photos/111388964237560787781/album/5362166283613539361/5366587361195860994

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.

* 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!

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

Or some Dell?

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

specs Core 2 due
