Topic: 24 GPU RIG - page 3. (Read 1747 times)

Sure, I posted it in another thread. Just buy used DL580 G7s. They have 12 PCI-E slots (with the PCI-E extension board) and typically come with 4x 1200W PSUs. Just buy whatever 12 video cards you want, 12 risers, build a little rig to hold the gpus for $10, and the PSU adapters so you get the 8 pin output (or go with the break out board that allows you to wire in). $800 +/- $400 (depending on whats on ebay at the time) + cost of GPUs. They have 4x 10 core processors (typically, some of the servers on ebay have older 8 core processors).

Can buy everything you need except the GPUs on ebay. Hell, you could buy the GPUs there too but I don't know if I'd trust them. I found some pretty good deals on used tesla equipment too (since you're a nvidia fan).

Since I posted it in another thread a lot of people have been picking ebay clean of the cheap DL580 G7s.. But there are still some available... I stopped mining with GPUs awhile ago and am mining with other solutions.. If you want the cheap DL580 G7 you'd need to setup alerts on ebay and check regularly. If you don't care so much about CPU mining you could also go with the DL580 G6, the DL580 G5, etc. The G6 and G5 have PCI slots and less PCI-E though. Not sure exactly how many. But they're also significantly cheaper, you can get the G5/G6 for like $100-$300.

Example: https://www.ebay.com/itm/Premium-HP-DL580-G7-Server-4x2-26GHz-32-Cores-48GB-RAM-P-410i-iLO/172908198868?hash=item284221bbd4:g:jRIAAOSwmkpZ57Tx

If the server you order doesn't have the PCI-E extension board you can just buy one.. Here's one for the G5.. https://www.ebay.com/itm/HP-449414-001-System-I-O-PCB-PCI-E-PCIe-Express-Board-ProLiant-Server-DL580-G5/282582004180?epid=6006039039&hash=item41cb3331d4:g:SGwAAOSwBt5ZEXZj

Here's a G7 with no riser and no memory (just buy it separately) for $200 -- https://www.ebay.com/itm/HP-Proliant-DL580-G7-4U-Server-4x-E7530-6-Core-1-86GHz-No-RAM-HDD-DVD-P410i-RPS/172980741588?hash=item284674a5d4:g:zMEAAOSw5VtaCcqE

Here's a G7 IO / Expansion board for $120.. Add it to the server above for $200 and you get 12 PCI-E slots + 4x 1200W PSU for $320 (just add $50 of memory and $25 ssd)

here's a cheaper G7 IO expansion board only $66! https://www.ebay.com/itm/HP-DL580-G7-PCI-E-Riser-Card-588137-B21/172984027345?hash=item2846a6c8d1:g:BaUAAOSwCU1YwEqh

Plus, these systems all have ILO remote management which means you can hard reset the server remotely! look ma' no hands!

LOL, Really? Funny,

First...

WhatToMine has it at $19.35/day and only using 1680W.
Goliath will make $41.90/day on Nicehash (just cryptonight) @ ~4kW
and $114.78/day on neoscript

Second, show us the system and where to get it as well as the stats please? I'll take 10 of them.

Did not test G4560. The G4400 just did not have the processing power to handle 9 GPUs. they system would blue-screen. It took for ever to enumerate the GPU's and when you remote into the system all input lagged. Since the majority of the cost of a system was in GPU's, i did briefly consider the i9, agreed LOL. My cost on the i7 7700k is less than retail (of course) so lets say less than $330 and the cost of the i5 6600k is less than retail, say $250. The 6600k matches or outperforms the 7700k, taking into account cost & TDP.

Three months of testing various components & configurations, tweaking, technical support with all the vendors. Again the MB/CPU/RAM/SSD are only a fraction of the system cost. Adds maybe 10 days to the ROI.

As to AMD - I would would not touch one. I wouldn't even put them in the system if given to me for free. nVidia was selected with keeping the future in mind. You don't even have to mine coins in the next few years because there will be a high demand for Cloud AI, Smart Cities, Self Driving cars. You could sell Computer power to schools or anyone else that is looking to push their CUDA code to a supercomputer. This cannot be obtained with a AMD at this time.

I can get a server that will support 12 gpus and includes power supplies (4x 1200w) suitable for 12 gpus for around $500 -- and will generated around $125/mo of monero. Cost for risers, psu adapters and cables is another $300 at most. Total cost $3320 for 12 gpus ($276/gpu) -- ($567/gpu for vegas)... And I get a 40 core server in the process that is great for mining monero.

Even buying new consumer components as opposed to using used server hardware it shouldn't cost more than $100 per GPU for motherboard, psu, memory, cpu, small ssd, etc. Putting the total cost at $310 per gpu or $600 per gpu at most for vegas.

Your price is ridiculous. $29999 for 24 gpus = $1249/gpu. Why would anyone order from you when they can get the same thing for less than half the price?

There is absolutely zero difference between i5-6600k and g4560 in terms of "maximum lifespan and stability". If anything, g4560 will run a little bit cooler, consuming tiny bit less power. 6600k is a waste of money on a mining rig. And i9 is just lol. The only reason I commented on this is because you said that "low end standard CPU's, ie G4400 will not work beyond 8 GPU's, 9 MAX on windows". So I was curious about why they will not work. G4560 works.

Due to contract with distributor...System Builders/Re-sellers cannot disclose cost for components. But i can tell you they are not $1249/ea
Lets just say $700-$800. Your number is the retail price for 1 system divided by 24 GPUs.

Care to explain to me where the cost for everything else is?

RX570s are $210 a piece.
It's possible to get Vegas for $450-$500.
You're asking people to pay $1249 per gpu.

Impossible. I'm using Distributors with volume break and there is barely any profit to be had. I am not building each system. I have to pay builders, their insurance, taxes, custom packing boxes and material, etc. Just trying to break a American based company into the market. Once again, the system is profitable and stable for a long period of time.


As I stated in my GPU test section. Only the MSI was stable. Why? I cannot tell you. I Love EVGA but was so disappointed as it was the slowest and most unstable GPU. Plus, I had originally went with 4 EVGA Titanium Power Supplies and they did not even send enough VGA cables and wanted to charge me for more.



This system is all about maximum lifespan and stability. The MB/CPU/RAM/SSD are only a fraction of the overall cost. Because of this I went with the higher end. It was going to be a Intel i9, then i7 7700k was tested, then i5 6600k. The i5 performace perfect and the is priced lower than the 7700k.

The bottom line is the overall profit. If the ROI is 10-20 days higher for the ability to "Plugin and Go" for years, then we met our goal. The 6/8/12/16/19 GPU Rigs are just not as profitable.

Now, stability. Each MSI GTX1080ti is initially set for: 65,75C,65,750
I then adjust each card targeting 610MH/s (Lyra2REV2)

Every GPU is different even though they are the same. Do not SYNC all Like cards. DO tweak individual.
Closed Loop Liquid Cooled GPUs cost ~$50 more, but cool better therefore you can raise the settings higher while staying under 75C.

3x the cost per gpu over just building it yourself. Price would need to drop to around $10,000 for this to be a good buy.

One more point i have to criticise is the long building time.... 5,25 days, yeah for sure there is your testing phase and so on but this is a product which you are able to build in 2 hours and setup in 2-3 hours so it should run perfectly after 6 hours and not 5,2 days.

Why? I don't know about G4400, but 2-core/4-thread CPUs definitely work in windows with up to 19 GPUs. That's G4560, for example, which is a lot cheaper. 6600k seems like a waste of money.

In my opinion and in our company's opinion this is a very bad mining rig => you need to use good equipment which is uselles at mining at the moment but you need to require good system standards.

The biggest 2 problems of this miner are:

High investment cost....
24GPU miners work like crap. We expiremented for 3 weeks with a 24 GPU miner and these one are not working stable. The stable working of a miner is very important.. always reboot or else is annyoing and time consumptioning.

Because the low end standard CPU's, ie G4400 will not work beyond 8 GPU's, 9 MAX on windows. The SSD is for Swap File which is quite large for 24 GPU system. The CPU that performed best for price was the i5 6600k. We also factored in each components overall rating, quality, performance and price with the intention of providing quality, stability and lifespan.

Then you take into account, say $350 for standard cheap MB/CPU/RAM/SSD versus $820 for the quality (and that actually runs stable) That is a fraction of the overall cost. GPUs are the primary component here and I found that the MSI GTX 1080ti 11G was the most performance and rock solid stability. Yet when I tried to put in a smaller overall footprint I had a heat issue. There for I tested the MSi Seahawk. I was not only able to make the overall system smaller but packing the GPUs closer, I was able to run the system at higher rates due to the liquid cooling and still have great stability with a maximum HASH/Power. At a cost of $50 more per GPU - it's was definitely worth it. The GPU's alone are ~$20k. This system is optimized down to a single (not 4 or 6) MB/CPU/RAM/SSD and 4 PS. This increases profits as well.

Any reason why you want to go for very expensive motherboards/cpu/ram and ssd?
It makes no sense from a mining point of view.

FYI: Please take a moment to read the thread before voting. Pay close attention to @senseless as he/she has good some points if you are a advanced IT and can build your own.

Product: Galioth

This post exists currently just to determine interest. To meet minimum for distributors we will need 500 units in the batch. If we reach that goal a page will be added to our website for the pre-order page. We will announce via Twitter five (days) ahead of time to allow customers to prepare funds and place order.
Please excuse any typos I may have missed, as this is just to see if there is even any interest in a system of this type.

Unlike other vendors, we understand how hard your investment was so you will be able to track your order on our website. The available status states (in order) are:
- Placed         Your order was placed, confirmed.
- Cleared         Your payment cleared, Your locked in.
- Pending         Your system is in Build Que, but not yet being build.
- Active         Your system is being built by {System Builder Name}
- Tweaking         Your system is being configured and tweaked.
- Burn-In         Your system is currently being tested/benchmarked.
- Documenting      Your system benchmark, manuals, etc is being prepared.
- Prepare         Your system is in que for packing
- Packing         Your system is now being packaged for shipping
- Shipped         Your system has been shipped, Tracking number attached.

Expect the turn around time from ACTIVE to SHIPPED to be ~5 days. You will get an email on each status change.         

System
- All components are the best in thier class. We went with ASUS Motherboard, Intel processsor, G.Skill Ripjaw RAM, Samsung SSD and MSI GTX 1080ti Seahawk GPUs.
- Each system requires two (2) dedicated 120V/30A breakers each with a double outlet.
- Build Time is approximately 10 hours.
- Configuration & Tweaking all components for maximum performance takes approximately 30 hours.
- Burn-in / Testing is 72 hours. You will get the results with your system.
- Packing and Shipping 4 hours.
- Total system (out the door) time is approximately 126 hours (5.25 days)
- Built in the USA and obviously shipped from the USA (Houston, Texas)
- Payment will be Pre-Pay for March Order.
- Systenm will be built and shipped in by order (FIFO)
- Payments accepted are Direct Bank Deposit or Bitcoin.
- Shipping is included.

GPU 60 Day testing
- ASUS. Not tested as they do not have a closed loop liquid cooled unit
- Zotac. Not tested as they do not have a closed loop liquid cooled unit
- Gigabyte. Tested, nominal performance, rejected due to price per unit vs. performance
- EVGA. Tested. Less than nominal performance. Unstable over 68C. Rejected
- MSI. Tested. Good performance. Stable at 80C. Each unit AVG $3.75/day (8 GPUS) and $4.00/day (24 GPUS). Accepted.

Profitability
- Nicehash was used for testing period and is the suggested and default on each system.
- Our test showed ~20% increase in mining revenue every 30 days.
- Most profitable aglo's (mined in test period) where Lyra2REV2, Keccak, Equihash, Blake2s
- Last 7 daily profits (as of 13 NOV 2017 - 20, NOV 2017) were $91.67, $92.30, $84.33, $89.74, $90.04, $99.17, $98.41
- Predicted profit (if/when) shipped (1 MAR 2018) is $147.20 USD per day, for ROI of ~204 days. This assumes last 60 day trend of Bitcoin and ALts remain consistent.

Expected Lifespan
- System was designed with a maximum lifespan goal. System should run for 72 months with no failures. The GPU's default settings have been optimized for maximum Hash/Power factor over time, therefore are not running at 100%. Each GPU has been individually optimized.
- We suggest picking up one or two MSI GTX Seahawk cards for backup. We have found that mixing GPU's induces instability for some reason.
- You may of course change settings to your desire. However, we strongly suggest you leave everything as we set it and just mine away.
- Predicted total income (not including trend increase, but current earnings) over 72 months is $201,480 USD, Profit per system is $171,480 USD

Warranty
- We guarantee upon upacking, hooking to power and ethernet that when powered on the unit will start mining (Nicehash on our account!). You will need to stop and configure for your account.
- The manufactures warranty applies on all components.

Estimated Cost (assuming distributor cost raimain the same by march +/-5%)
1   $29,999 -> ROI = 312 days
2   $29,499 -> ROI = 307 days
4   $28,999 -> ROI = 302 days
8+   $27,999 -> ROI = 291 days
