Have a couple 1200w psu's coming from Sidehack and working on getting picopsu and riser rig package from Finsky. Found a good outlet for 1500w common slot psu's that will work with Sidehack breakout boards. Figure as long as I manage power then 1500w psu will handle 8x 1080 ti well. Am I wrong?

[flminer]

Why not spend a little more and run 8 per mobo with server psu and pico? Just curious as that is what I am thinking of doing.

well  6 and 8 per mobo   involves riser trust.

and on really big scale it is the way to go.

question is  what is really big scale.





other info a listing from me.

DAM! LOL Seems like you always sell right after I spend my btc! With ordering from Sidehack and Finsky am tapped out.

I will be running a 5 x 1080ti format at about 1000w-1200w .... this would give me about 4.xx amps per rig
 and with 20amp per circuit, I can have 4 rigs per circuit.

Running 8-10-12 rigs in one mobo is quite a feat in terms of rig cage size, psu, heat movement and cabling.

Its so tempting though.... but I have too many horror stories in my RX 480, 470 ETH days...

My current gold standard for my RX470 ETH farm below.... undervolted, slightly overclocked 27-28MHs per GPU.

smOS RX, 6/0/powerstage=0 and 162-165MHs per rig at about 1000-1050watts using Platinum server PSU 1200w.

No more tangled cables, bulky PSUs etc.

Would want to do dual PSU in future but those server PSUs are sold out everywhere.

 I don't see a single 1500 watt power supply handling more than about 5 1080 ti at one time reliably (6 if they are FE cards *maybe* but that's pushing the supply to the limit).
 You MIGHT be able to push it to 6 (aftermarket) or 7 (FE) with a fairly hefty lowered TDP limit on all the cards but keep in mind that the cards run at 100% TDP and normal BIOS voltage when the rig first boots up, for a few secs at least, 'till whatever you're using to SET the lowered TDP kicks in - definitely put a sleep of at least 10 and preferably 20-30 seconds on the first line of your "start up the miner .bat file" to give everything else time to get going and initiated.

 1500 + 1200 should handle 8 comfortably - 1500 for 5 cards, 1200 for the other 3 cards + the rest of the system.


 Don't believe the "1080 Ti is a 250 watt TDP card" information - a LOT of the aftermarket cards set the TDP quite a bit higher to give them the OVERHEAD to be able to set those high "factory overclocks", and even on GAMING loads (which don't load up a GPU nearly as consistantly as mining does) a lot of review sites quote some of the 1080 ti cards as being MEASURED at 290 watts or so usage.

you are right QuintLeo - 5 x 1080 rig is a challenge because I noticed power draw for high end 1080ti and it runs best at higher clocks by default power draw which is often around the 200-250w plus mark -- so if you have better and high end 1080ti and want to run beyond 5 cards -- you surely need a twin psu solution. I plan to use 1200w x 2 server psu with my 5 card rig setup.

listen to QuintLeo - I have 6 that's been connected to my killowatt for the past 3 days and the draw from the wall is 1310 watts - that's at 70% TDP so at 100%... good luck!

Why 2 vs 4 card rig setup? Why do you believe this is the best setup, just asking because I'm curious and want to build a 1080 TI rig

Furthermore, what is reported to be the best 1080 TI card?
https://www.newegg.com/Product/Product.aspx?Item=N82E16814137115&cm_re=nvidia_1080_TI-_-14-137-115-_-Product I'm partial to this because it has green xD

[VoskCoin]

I have 4 x 1080tis and 4 x 1070 currently.

Thanks to the BTC rise (even at 2300 something it is still an incredible level).... ordered another 4 more 1080ti

I decided to standardize on the MSI Z270A-Pro for NVIDIA farm -- compatible perfectly with fullzero's nvoc Linux OS.

Late last night, my group put another early order of 12 x MSI and Aorus 1080ti but....... it fell through..... got email from supplier NO STOCK and both MSI and Gigabyte have not updated next shipment schedules.

Supplier has indicated that crypto currency boom basically getting practically all NVIDIA GPUs off the shelves as soon as they are available in store and basically no stock for online sales.

If you have not bought that 1080ti or still deciding..... my advise is get them now before its too late.

Its bad enough that practically RX500 and RX400 cards are hard to come by nowadays...... now NVIDIA has gotten the crypto bug too.

I suspect that by the time VEGA comes in.... every card from AMD or NVIDIA will be above normal price.

I think Intel will soon come to play in the GPU arena.

I will not be surprised if we will see "unknowns" from China coming out ...... like this brand called COLORFUL.

can't wait! keep us posted

re-emphasizing dream..... after the BTC blood bath yesterday.... that 3rd GPU farm will remain a dream for now.....

I have a hunch that if we start our 1080ti ZEC project early..... we will be a few steps ahead than the rest of the AMD boys.... especially the correct boards, config and tweeking for a proper NVIDIA ZEC farm

that is a lot of Watts for those 6 RX470s there!  
You *should* be able to achieve a 200-300W reduction by proper undervolting (in BIOS if you are using smOs).
With the Sapphire cards, a BIOS mod to undervolt takes like 2 minutes.

Why 2 vs 4 card rig setup? Why do you believe this is the best setup, just asking because I'm curious and want to build a 1080 TI rig

 4 card rigs are a lot harder to keep the GPUs cool, unless you use risers.

 I personally prefer 3 card rigs, but current motherboards are either WAY too expen$ive to get proper 3 cards spacing for good cooling on 3 FULL LENGTH boards, or I can use the low-cost stuff and make a point of putting a "short" card in the 3'd slot (like the Gigabyte "ITX" 1070 model) to allow the middle card to have ONE fan completely clear to keep it cool enough.

 3 card rigs are a LOT easier to set up then riser rigs, in my experience tend to be noticeably more reliable than riser rigs (riser rigs ARE easier to keep the GPUs cool on though), and the cost difference is very small to nothing after you factor in the cost of the risers, the extra amount of connections needed on your PS (or the extra CABLES to add to it) to power the risers, and the problem that power supply cost per watt starts climbing noticeably faster past about the 650 watt level vs the "additional costs" of 2 MB, 2 CPU, twice as much RAM, 2 HD/SSD/USB keys.

 You also get the nice part that if you DO have a rig go down, you only lost HALF of your hashrate from 6 cards instead of all of it.

 If I could get reliable access to that Katana-model 1070 or if someone that DOES normally sell to the US builds a similar model at a SMALL premium to 2-slot card designs, I might start going 4-card rigs regularly, as THOSE things you can keep cool fairly easily on boards like the Biostar Racer board that Phil liked that have 4 slots properly spaced to mount double-slot cards ON the motherboard.

 NVidia and AMD make "compute" single-slot-wide versions of many of their higher-end GPUs but those things are CRAZY expensive definitely not a good choice for a mining machine (unless you can get a good used one for a LOT off new pricing).


 The really scary part - as of this morning, the only RX 4xx boards I could find for sale anywhere (I do NOT look at eBay, too many bad experiences there) were all priced HIGHER than the low-end of the GTX 1070 - and the RX 5xx cards I could find weren't much better.
 We might see a big short-term move of folks to NVidia because the "lower cost" part of the ROI question on the RX 470/480/570/580 isn't THERE any more vs the 1070.

my Sapphire cards are mostly Elpida memory.

Yeah, I have two of each, Samsung (8G) and Elpida (4G) variants.   Their hash rates are about the same ~27MH/s.
Nothing fantastic, but they are consuming 105-110Watts each.
Even if you are not familiar with BIOS editing, it is really easy.
Get a copy of the current bios from the gpu with atiwinflash (assuming Windows here) and save it to a backup file.
Open the BIOS file with HxD hex editor and search for this string FF 00 01 07 0C 00.  Then verify that the 4 bytes immediately before this string is
8D 00 xx yy.   Use editor to modify xx yy value.   Say you want a 50mV undervolt, then assign xx yy = F8 FF.
(reason: F8 = -8.  Multiplied by 6.25 -> -50).   Ok, do not change anything else.
Save the file as bisomod1.rom or some such, then reopen the file using Polaris Bios editor. Then save the file so that the checksum gets updated.
Use atiwinflash to flash the card with this bios. Enjoy!

One thing with the 470s, My cards all have different bioses.  They are really different on what they accept wrt amount of undervolt, memory overclock amount etc.
Therefore, try a low undervolt value initially.
