Topic: Fourth alt coin thread last three got oversized. - page 45. (Read 108938 times)

I can totally afford the warehouse i posted above right now.. it would make a great location to expand from.. the only thing is i have no clue how i would go about cooling.. i went and checked out the units they had.. 1 had a window a/c installed on the small door leading into the unit.. but that would be cooling the entire 400sq ft with a window unit.. dont think that would work.. the unit was pretty air tight outside of that.

Which brand of risers are you using? all the ones i bought are 4 pin female to male sata... i for the life of me are seeing no listings for any cables from 4 pin female directly to 6 pin female, i did manage to find a listing for 100 female 6+2 PCIe connections for $25.00 shipped and a listing for 100 female 4 pin molex connectors for $17.00 shipped , but they are both coming from china, about a month on the shipping.. maybe something to look into in the future.. then you can buy a roll of high quality wire and build your own custom cables to the lengths you need going directly from the riser boards to the server psu breakout board, and then make your own cables from server psu to gpu... those connectors alone would provide you everything for like 8 complete mining rig setups using server psu's


Also could just buy the 6+2 connectors and salvage the 4 pin female molex connector that came with the riser.. just remove the pins and reuse them on new wires and add the other end with the 6+2 so you are fully covered and not going through multiple connectors.. heck years ago i did in a pinch took a psu cable i had because i had no female end cables anywhere, i just soldered them directly to the cd drive to the 4 pins.. worked flawless for years that way

I was thinking about server PSU's as well - The risers I have are the PCIe ones but they are 6pin to SATA; not sure but I think you can use a 6pin to 6pin instead - I haven't hit the search yet since I wasn't really thinking about it till you said that.

This is actually why im thinking of switching over to the server PSU route.. but i didnt think about the sata power off of them.. crap..... the server psu setup i ordered only has the 6pin to 6+2 cables and breakout board... i ordered one set just to test out, the price of them is just to hard to beat honestly... now i gotta figure out what to do about the sata power now.. well back to researching

And just a side note what I'm finding the most difficult to deal with - these dang power supplies!

like 90% of my issues are the PSU's! I thought I had some bad risers, turned out, the SATA cable wasn't powering the riser correctly. Swapped to a different set and it powered up just perfect.

Also finding out, cables from different brands, DO NOT like to work with other PSU's. Rosewell definitely won't even plug into my EVGA's some proprietary plug, then some other plugs not working with Corsair or corsair not working with another. It's been nuts, but it's my fault for not standardizing which is what I will be doing next.

I literally just started dumping BTC into hardware as fast as I could, now that locations are maxing out and things slowing for me just little things I'm noticing.

@ VoskCoin yes that's pretty much what you have to do, I've been expanding trying to find more space and more power - so IMO if you've got a chance to grab it and it's affordable, do it

Stox - I'm like the EVGA SC2 and even the FE seems to be running cooler than most my other cards.


And @ Everyone else -

Man running into an issue - I have the electrician coming over later today or tomorrow but I can't decide on the 30A breaker he's installing what plug to go with -

L6-30 so I can connect PDU's is my first choice but they won't be here till next Friday.

I also have 3 APC SMT3000 UPS that can handle 3kW load each, but they run off of 120v and use L5-30 plugs so I will not be able to use them if I run 208v so I guess they'll just stay in hibernation for now

Wanted to pick yalls brains.. what 1080ti are you liking the most and why...
I have gotten to play with 3 different ones and ill report them as follow.....

1) EVGA GeForce GTX 1080 Ti FTW3 Gaming-This card seems to be the most stable out of the 3 when overclocked 250+ on core, allowing great hashrates at much lower TDP than the other 3, but fans are 2nd on noise level to maintain 69c.... CON- card is the most power hungry overall and the drop in hashrate per 1% TDP is the fastest, so seems to have the lowest range you can undervolt it before it becomes inefficient

2)MSI GeForce GTX 1080 Ti Armor 11G OC-This card honestly sucks at 100%TDP, just horrible hashrates and heat levels... but when you undervolt this card and push the core this card is amazingly quiet and performs pretty awesome hashrates when optimized with average temperatures.... easily the most quietest card when fan speeds above 70% CON- This card seems to be hurting from temps the most or some sort of safety is set on this card more so than others.. for example i had my friends pc sitting with the side open with the temps stable at 69c at around 60% fan speed on auto.. as soon i turned on a box fan to blow on us while we played around with my other computer, the sheer cooling from the box fan immediately increased hashrates by 150-200Mh/s on skein... with reported temps of 69c...not sure where the thermal throttling is occuring or what not..

3)Gigabyte GeForce GTX 1080 Ti Gaming OC 11G-This card is kinda average at everything except power usage, this card has the lowest of the 3 in hashrates when tdp is lowered, but the drop off curve is the longest.. so you can push this card all the way to 50% tdp and the hashrate is way better than the top 2 cards at that level.. so i can see this card being a good card to use if you are having heat issues, because it can be reduced to 50% tdp and still manage decent hashrates and sit around 55c on air... but this card is the LOUDEST when you crank the fans up, actually kinda annoying tone to the sound..

From my brief conversations with the guy who answers the phone, they are all a little different from previous renters moving electrical lines and such, some have built in enclosed shops that can be removed, since they were left by previous renters... he told me they all have 200Amp Connection... so if that is true running 220-240 lines is not a big deal.. the only thing im concerned about is how to properly cool everything, they seem pretty much sealed up when the door and rollup is down...

I think warehouse expansion makes a lot of sense, how would you deal with your power needs though? I doubt any 240v would be installed / how many amps would you have?

I will have to do some more research on this.. from my understanding Alexis miner is only a windows thing.. so im kinda stuck on windows for now.. thus the question in regards to windows...

In regards to TeamViewer, i know very little about it, but i know what it is really.. couldn't you just team view directly to the mining rig? i know you have to know the number and password to connect, but do they expire if you just leave it open?

Also been thinking about expanding into a small warehouse myself about 35 mins from me.. some pretty affordable rates on them.. i currently have 6 x 1080ti's (sadly 2 are not mining due to issues with risers not working for me), but soon this will be corrected as new equipment will arrive over the next few days.. if i go off my average of $12.80/day per card since ive been on skein.. thats plenty to cover the rent on a warehouse to not have to worry about the issues of it overloading my condo power....

sorry been slammed with work need to catchup on thread,

What's the status on R&D with the gigabyte cards? going to put together my two rigs this weekend if the my msi aero even get delivered >:l i have the gb cards at least but was planning on putting them in the gaming rig I am trying to build

NOTE ebay bucks is back @ 8% thanks again to phil for putting me onto that idea for these builds lol

I use this app called mobaxterm on Windows to vnc and ssh into my windows, nvoc and smos rigs.

The mobaxterm app is installed on a old Lenovo Pentium Duo PC 8gb ram in my warehouse.

From home, I Teamviewer into this machine from my iMac and basically access all my rigs in the warehouse.

All automatic power cycle off/on/resetting functions are controlled by Tytanick's SRRv1 and soon SRRv2.

I use Windows and ethOS for my ETH rigs in the past, but now standardized on smOS Linux to simplify the entire mining operations for AMD rigs.

My NVIDIA rigs are mixed Windows and nvOC Linux.

I use TightVNC to manage the Windows rigs and SSH for smOS and nvOC if I am physically in the warehouse.

-- the Teamviewer session will be like the master console to access VNC and SSH launched from mobaxterm if I do remote from home.


Actually the blower/reference style design is better if you have small clearance in between cards.

Also the blower pushes air frontward and this is excellent for directing the hot air into the hot aisles -- usually this design is better for large farms.

For me, I will standardize on 1080ti and 1070, on a 5-6 x GPU rig format and manage the power requirements.

This 7-8 x GPU concept is nice to fully leverage density but the fact remains.... you need bigger PSU, better mobo, more riser BS, and probably have to babysit these rigs constantly to stabilize them.

I have learnt my lesson in my existing ETH farms, 480s, 470s, 6xGPU standard EVGA-1300w PSU, and more recently 1200w platinum server-psu/pico/bb setup. Running so stable and cool, I don't even have to worry about them too much, especially with SRR system in place -- its as good as lights-out mining operation.

I honestly dont see this being a viable option really.. it has blower style cooling, which from my readings are the worst card designs to mine with due to them naturally running hotter, and you can pickup a EVGA - GeForce GTX 1060 6GB now over on newegg for $207.98 after rebate.. so if its essentially mining at the same rates, why take a 3 month warranty for roughly the same price....also what is the resell value gonna be on that card in the future....

Similar to the panda concept

http://cryptomining-blog.com/8784-seems-like-nvidia-is-making-a-video-card-especially-for-mining/

Looks like NVIDIA is ready to pounce on the mining world.... GTX-1060 Mining Edition?

"....8x of these GPUs: 200 MHS for ETH, 2500 Sol/s for ZEC, 4400 H/s for XMR...."

Do any of yall remote into your computer on windows?
I am asking because all the setups i have now i can easily use a monitor and keyboard on, but once you get past a few it is going to get annoying to perform actions on a rig...
I just bought a Dell Workstation yesterday after a recommendation from someone who runs 40+ of them on garage shelving suspending the GPU's above the case with it layed on its side, $166 for a dual xeon workstation with 5 PCIe slots and 875watt proprietary PSU with Windows 10 PRO and 1YR warranty on parts and labor, reason i mentioned proprietary is because it has PEG connections on the PSU i was told and i would need adapters from PEG to ATX PCIe to power GPU's or i might even just run a 2nd PSU to make more simplified... The person i was told about this doesnt actually use the windows 10 built into the workstation, he uses bootable EthOS thumbdrives to run his rigs, but he has AMD and from what i understand ethOS does not support Nvidia

EthOS he linked me if your curious https://gpushack.com/products/ethos-16gb-usb-3-0

Easy

this is 3 1070 ti's  running at about 1375 on my monitor screen

How will you do a fair test?

Not an excellent test . to be fair  test should be a week at least.

last 24 hours  I mined 0.0469089  my hashrate was 8.6 to 9.0   about 10 1080ti's  so  I did  0.00469089  that is $13.31 a day per 1080ti.

Also  one must understand  that mining the coin directly  can allow  cherry picking of exchange rate.  that is the bigiest advantage of mining a coin directly.  Of course  if you hold coins  beyond   a day   you increase  the chance of gain or loss .

my mining on zpool  and I moved and varied my hashrate since I really was not testing.

I am deleting both posts but quoting them as they are not accurate testing and are presented as such.  BTW my numbers were not done as testing, but I will set up a more correct method  for zpool.

All info from the other two posts are here.
