I finally got the balls to max the onda b250 board   with 8 1080ti's

using the corsair  ax1500i

5100 sols is nice

Hmmm... Aren't you cutting it a bit close with only 1500W?

Also how are you keeping temps so low? I can't stop thinking the GPUs are too close on such a setup... 😐 Unless they're all hybrids?
Edit: Ok I see they are. No issue then.

    yeah  1370  is hard on a 1500 watt psu.

  I have 4 of them  and I am willing to blow up one of them to see if they can do 1370  for a year

Just sold a bunch of 480/470s for an average of $370 each. Left with 6 polaris cards for sale (let me know if interested). They are 5x sapphire pulse 570 4gb and 1x 580 8 gb HIS. They were used since last May in a dust free environment, undervolted to 875mv.

I stopped gpu expansion for now, it's too difficult to find them at a good price. Even my early jan order of 1070tis from a local supplier has yet to arrive. Right now I'm focused on HDD mining. Takes 16 months to payback HDD mining now, but with new proof of capacity coins coming I believe it's viable. Worst case scenario the $150 8tb drives can be liquidated for $120. HDD is low returns, but low value at risk. Unlike GPUs, where a $400 1060 6gb can drop to $150 in value if things go south.

Took 3 weeks and I have 300tb online. Looks like another 6 weeks to get the full 1pb running. An Rx480 it takes 1 day to get 1 drive plotted and optimized. 1950x can do 2 per day.

For anyone who's interested to do HDD, I recommend NOT going for a threadripper build. Go i7 8700 build instead, no gpu needed. Add another rig when needed. The rig cost per drive is similar, total compute power for plotting is similar too. Also don't be like me, connecting 10 drives per usb 3.0 hub. There's new miner software that can scan a 8tb drive in 17 seconds now, limit to 5 drives to prevent read bottlenecks.

I have  3 omen pc's that could do 32tb each  and mine 2 1080ti's

Is it viable to  mine gpus while the pc mines hdd?

you could be on to a good idea.

I currently have 417TB online for HDD mining.  Plot speeds are good at around 90,000 nonces/min on a dual E5-2660 V4 rig (paid $350 each for ES versions of those CPUs):



And scan speeds are really good:



Takes around 20 seconds to scan 417TB worth of plots.

[crazydane]

Anyone in here having setup 6+ GPUs on a riserless mobo with a custom water loop? I suppose that would be a good setup too, you'd need need two 360 rads I suppose to dissipate the heat...

Crazydane did it.

I was going to but decided to go hybrids

I got one rig with 4x MSI 1080Ti's on a custom water loop.  2x 480 rads and 1x 240 rad.  Despite that, I'm still seeing a 11 degree temp differential between ambient and coolant temp, suggesting I'm under radded.  That said, those 4 1080Ti's on water hash like nothing else I got:



Btw, I'm totally hooked on Hive OS as you can probably tell from the above screenshot.

Okay  417tb  earns what per day  and how much power does it take.

[crazydane]

I'm doing around $17/day right now, but I have had $80 days when I mine a block and/or the coin is valued higher.  It has been above $0.10 recently and will hopefully bounce back.

Average power is a little over 900 watts:



Plus I got a mini split keeping temps in check that consume another 150 watts or so:



So current math does not really show a great return, especially if you were to buy all the hardware from scratch (I had a lot of mine already).  But I have been hodl'ing everything I have mined since last summer and am hoping it will be a good long term investment.  As KaydenC mentioned, if POC goes belly up, all those HD's will still be worth quite a bit.  In my case, I'd keep them for multimedia (already got another 100+ TB server for that).

[philipma1957]

do you run  the hdd mining with or without gpus

[KaydenC]

I have  3 omen pc's that could do 32tb each  and mine 2 1080ti's

Is it viable to  mine gpus while the pc mines hdd?

you could be on to a good idea.

Yes, 32tb is not an issue. From rough estimation an i7 8700 can scan 50x 8tb drives before maxing out 100% cpu usage. I'm extrapolating my 1950x's performance, which is underclocked to 3.3ghz use 40% cpu scanning 40 drives. I think nows the time to get in early on HDD, all it takes is a whale swiping all <$200 drives.

This $150 drive works: https://www.amazon.com/Seagate-Expansion-Desktop-External-STEB8000100/dp/B01HAPGEIE/ref=sr_1_3?s=pc&ie=UTF8&qid=1519479080&sr=1-3&keywords=8tb

Or wait for $160 WD easystores, which has 2 year warranty. The seagates only 1 year warranty.

Those are really good write speeds and no bottlenecks when scanning. ES cpus is definitely the better option. I once struggled for 3 weeks with an Xeon e5 2630v4 ES and evga x99 ftw K. never got it to post, bought 6800k and called it a day. Think I got a ES revision that's too early. haven't dived into ES again, but very cool to see it working. Which mobo are you using? Any rig pics?
Writing over my usb hub only has 40+ mb/s despite there being no bottlenecks. 120mb/s if directly connected to the usb port though.

My threadripper plotting. Underclocked to 3.3ghz. Using 25/32 threads.

do you run  the hdd mining with or without gpus

I run my 1950x with an rx480 (no choice, need a gpu to post). But gpu is quite troublesome to work with for burst. Plotting with gpu is 2 step process, plot to a drive then optimize to another drive. You can use a software called turboplotter to directly plot optimized for gpu, but then the speed halves...

For cpu once plotted it's already optimized. With price of gpus it's not worth using it. Crazydane's ES xeon setup seems like great value, definitely better than threadripper. But an i7 8700 should be easier to work with. Grab a mobo with many usb 3.0 slots, like Evga Z370 FTW or gigabyte Z370 XP SLI, 5 drives per usb3.0 port, cheap 500w psu, borrow 16gb ram and all good to go. When mining just 4gb should do.

 I have so much gear buying mobos are not something I need to do.

I need to explain better  I have these 3 pc's

I can put 4x 8tb  hdds in them.
that gives me 96tb for hdd mining
I still want the gpus in them to mine zec

and the cpus to run the hdd mining

[crazydane]

Which mobo are you using? Any rig pics?

My Burst rig consists of 5 Supermicro 846 chassis' which hold 24 disks each.  The master one has a Supermicro X10DRi in it and the 4 slave chassis's just have a small power control board to power on the PSU's.  The fans are all connected to the SAS2 backplanes.

Master chassis internals:





I'm just running 2 16GB DDR4 DIMMs per CPU, so I'm only using 2 of the 4 channels.

There's one LSI 9211-8i HBA with 4x6Gpbs lanes connected to the internal SAS2 expander.  And there are 3 LSI 9200-8e HBA's which each provide 2 4x6Gbps SFF-8088 connectors for connecting external chassis. So I can have a total of 6 external chassis connected at once without resorting to any daisy chaining.  The 5th card on the far right is an Intel X520 dual 10Gb NIC connecting the server to my 10 Gb switch.  There are plenty of PCIe lanes to go around, so each card has 8 at its disposal, so no bottlenecks anywhere from an I/O perspective.

Between the 4 HBA's, I have a total bandwidth of 4x8x6Gbps = 192 Gpbs.  So my theoretical throughput when reading and writing is 24,000 MB/s. 

View from the front showing the 108 drives (lower 5 chassis) currently installed just starting to scan a new block:



The 2U 12 bay server at the top of the stack is a dedicated plotting rig atm.  It has a single E5-2683 v3 in it and can do about 50,000 nonces/min.  Below that is my media server, which has 24 6TB drives in it arranged as a RAID60 configured as 2 x 12 disk RAID6 arrays.  It is also spotting a 2683 v3 to handle transcoding needs for media clients.

In your case you would plot the 4 drives using CPU and read them using CPU. The gpu will not be involved in the hdd mining process.

Last month I returned 300TB (50 USB drives) from everyone saying what a pita it would be... thinking maybe it's time to reorder them just to play around.


I know you said i7 is better than Threadrippers, but I already have about 20 Rayzen 1700x's do you think those are good enough to plot efficiently?

I'm also wondering can I plot on the 20 different PC's then when they are done plotting, add the drives to 1 actual machine I plan mining on, or is it the PC that you pot the drive on, you have to mine on?


Super interesting stuff.

[crazydane]

I'm also wondering can I plot on the 20 different PC's then when they are done plotting, add the drives to 1 actual machine I plan mining on, or is it the PC that you pot the drive on, you have to mine on?

I do that all the time, no problem.  Just make sure to use the same ID for all the plots, and that the nonces don't overlap between plots.

I just run a script similar the the one below on any computer where the target drives exists:

Code:

@setlocal
@cd /d %~dp0 
start "" /belownormal "C:\Xplotter_AVX2\XPlotter_avx2.exe" -id 2597790682173387743 -sn 10600000001 -n 0 -t 52 -path c:\Burst\plot106 -mem 16G
start "" /belownormal "C:\Xplotter_AVX2\XPlotter_avx2.exe" -id 2597790682173387743 -sn 10700000001 -n 0 -t 52 -path c:\Burst\plot107 -mem 16G
@pause

-id - your numeric account id
-sn - start nounce of the plot
-n - end nounce.  Set it to 0 to fill the disk
-t - CPU treads to use
-path - target drive
-mem - amount of memory to use.  Unlike -t, -mem is allocated to each plotter instance, so the sum of them must be less than your total system RAM

You would of course want to change the -id value to whatever your's is, and the -t thread count and memory to your hardware.  I like to leave at least a couple of threads free for other stuff.

[QuintLeo]

As long as you don't duplicate nonce ranges, you can plot on as many machines as you want to.
BURST mining on the CPU uses very little CPU power most of the time, it works fine on my 5 card rigs with no noticeable impact on the GPUs doing their mining.

Returns though are very low, and the pools issue has been a major pain for a few months now - seems like someone(s) have it in for BURST and have been DDoSing the pools right left up down and sideways.

 Quite a bit earned via mining, lots earned via pool fees, and likely a couple hundred thousand or more of miners sold at probably $500-$1000 average profit EACH.

 Though I have to wonder if that "up to 4 billion" figure wasn't more of a gross sales/gross income figure.
