Happy New Years! Seventh alt coin thread!

It's true that 100% power provides more profit in the short term, but it's better to look long term. Less stress on components = less part replacements and it's really important for anyone running at some scale. It's not wise to crank up the power and hire extra people to fix stuff.

Large scale operations also have power limitations and 500 cards at 200w is better than 400 cards at 250w. For the casual miner sure, anything goes.

I'm about to touch 100 GPUs and some been running for a year now.. no replacements no problems.

However, lowering power to get more cards is an interesting idea..

The rude shocker answer:

only the mentally ill mine at max power.

fact not opinion so  to give you an answer  is pointless since only crazy people want to mine at max power.


Now do not feel bad  as I have driven my Fia Forte from Howell NJ to Atlantic City  at 105 miles per hour  when I could safely set the cruise control at 65 miles per hour.

and my answer is yes  I have melted cables at high power settings.

My advice  set to 190-205 watts and no higher

Phil that is just not true. My power cost is ~$0.12 kwh and I have built spreadsheets in the past for every single algo and power %, and no matter what the out is always more money by running at 100% or higher power usage.

I have always said if it works for you do it.

I know maxing cards  does not work for me.

 BTW  I was looking to get you to reply to the rude statement  as I don't understand how you don't kill your cards or risers maxed like you run.



If cards are cheap and space is big   but power available is low   you will get more hash  with more cards set to  60-70%

I have space at the array
and we did get a bunch of 1080ti hybrids at a good price.

If I set them to 180-200 watts  rather then 240-250 watts  I can do more hash on the same power.

the array caps at 30kwatts  per hour.  after that  power is no longer free.

We did get good news on the land in south jersey we may get the second array  sooner then we thought.

and it would be 40kwatts

Not bad. 40kw is enough to power about 6.6 rigs in CA in the summer and 3 in the winter.

[deadsix]

This is the main rigs shelve. 54 rigs can be placed here. Assume 1.2KW each it will put me below 65KW power. I intend to use no more than 60KW though. 16000cfm air flow. Hot air from rigs directly go to the back of the unit to be exhausted. Absolutely no hot/cold air mixing.

This looks super kool, are those Onda motherboard type 8 GPU cases? Keep posting pictures as it fills up, would love to see progress on it.

Phil were you trolling me?? I like it 

So here's my thinking: everything is already over engineered, so why not take full advantage of what these things can do? Here's an example that I can give real evidence to. I'm sure a lot of you guys use PCIe power splitters, the Y cables that turn 6 pin to (2) 8 pins, right? So many of them claim to support certain wattages. 6 pins are supposed to deliver 75w max and 8 pins are supposed to do 150w.

I have every single one of my 1080tis plugged in with (1) 6 pin -> (2) 8 pin adapters. That's "300w" (up to) being delivered via a cable that's only supposed to do 75w! That's insane right?! Not at all. Check the "Wire Gauge Selection Table 12 Volt Circuit" https://www.tessco.com/yts/industry/products/itm/automotive/get_wired.html

Notice how an 18 gauge wire on 12v can supply up to 40a on a 3' run, and these guys are only 6" long with 3 wires carrying the power.

Now, unless I am radically wrong in my misunderstanding of how this works.. by my math that single connector should be able to easily provide up to 1,000w of power before you have to worry about the wires failing. Suddenly, that 300w doesn't look so crazy!

And I'm only using that as an example, I am fairly sure that the components on the TI are able to provide far beyond their normal use specs. Can some of them be created poorly with parts that will fail quickly? Sure. Those are cards that would die eventually anyway.

I've been mining on and off since 2013, I have bought/sold over 200 GPUs in that time, not once have I had one GPU fail from being run at 100% 24/7 (fans excluded).

its not the wire 18 gauge wire  thats the limiting factor, its the connectors. their rating is far lower, they get dirty, lose tension, oxidize. that builds resistance and thats when the problems happen.

No I am putting the 24/7 number

The array will be 200kwatt devide by 5 to get 24/7 number.

Of 40kwatt


At soothaa yes I trolled a bit

This is probably true.. however I'm still yet to have one fail. Same goes with my GPUs.

So I had a little "fun" with the power stuff we've been talking about.. here it is in case anyone is interested!

I'm sure loose connections can cause issues but its not a normal occurrence.  People have all this outdated copy pasted 75w 6pin, 150w 8pin power rated stuff stuck in their heads and refuse to move forward.  I mean I understand its better to be safe than sorry, but I've been running 200w through 6pins for almost a year without any issues.  Just buy the right parts and not some cheapo china made breakout boards/cables.

So I had a little "fun" with the power stuff we've been talking about.. here it is in case anyone is interested!

 Hashrates look kinda low compared to my 1080 ti testing on one of my Aorus cards - but other cards DO tend to be lower at the high-end due to cooling limits reducing the boost clock.

 50% = 505 sol/s
 60% = 620 sol/s
 70% = 680 sol/s
 80% = 725 sol/s
 90% = 760 sol/s
100% = 780 sol/s

All at +100 core +100 memory, I've done a LITTLE playing around those settings but they are stable and seems to be right about the best hashrate.
The other 1080 ti cards I have (EVGA SC Black, ASUS "blower", Gigabyte 3-fan Windforce) match these numbers pretty much identically up to 80% or so then start dropping off a bit.


No, the PCI-E connectors WILL NOT handle 1000 watts or even close- you're overstressing them at 300 even if they are using 3 pins for +12VDC.
The KNC Neptune and to a lesser degree the Titan were NOTORIOUS for burning connectors a lot because they were trying to push 350 watts (ballpark) through them when overclocked.
You might get away with it for a while, but a lot of folks have BURNED connectors by pushing them too hard.
While the pins have a "free air" rating of 13 amps, they derate to 8 amps in the connector because the connector retains a lot of heat.

Yeah those are onda mobos plus cases that are on alibaba. Really nice cases with overkill 3700rpm fans. Keeps my 1070ti minis at 60 degrees.

[cptmike]

Thanks for the responses.
Going to look into lowering the power.
Right now getting 730 sol/s at 250w, fan 60%, temperature 62c. electricity cost is 0.07c/kwh

So I should for sure not use a single pcie cable (has two 6+2) to power the 1080Ti?
2nd card will be offline for a while, seasonic hasn't gotten back to me yet about getting a extra pcie cable.

Anybody else have problems turning off the aorus led in ubuntu?

[philipma1957]

Someone might be having the issue I'm having in my garage, so here it goes:

After I've added couple more rigs to my small garage setup (now 14 1080 ti total), my garage door opener stopped working from outside. Cue in pissed wife.

Did anyone tackle an issue like that? RF interference seem to block the remote signal from outside, extending the antenna to outside did not help (it probably hurt as I did not care for the wavelength of the remote signal vs added antenna cable length)

Any solutions?

psu's  may be issue not  gpu rigs.

get an fm radio  and try to find a channel that gets interfered with whne you turn on a psu.

rosewill tokamak does it.

if you find out a certain psu is doing it build a faraday cage around the psu.

That's strange.. this was with +150 core clock and the nVidia 388 driver. However with hashrate I prefer to err on the side of caution.

No, and I would never send 1000w through those adapters. But 300w does not even render the plastic connectors warm to the touch. If they're not even warm.. they're not failing any time soon. I can break out my infrared thermometer and start taking readings for y'all!

How much are you paying in rent for this type of room, if you don't mind sharing? How many rigs will you stack in there?

54 rigs will be stacked there, 432 cards. 88x 1050ti are coming which takes up 11 rig space. The remaining space can be filled with 150-180W tdp gpu rigs like 1070tis.

Rent is $250 USD a month.

The fans are so powerful that the clothing rack will topple over! I wish the rig cases have the option of fans between 2000-3000rpm.

Quick question here has anyone used Dataland branded GPU's.

I have the chance to get some 580's but being new to GPU's and haven't found much in the way of reviews.

Thanks

Holy cow, where/how did you find this?

I have never heard of them, but someone else may know about them. Did you find them on an Asian website?
