Happy New Years! Seventh alt coin thread!

Eventually some end up on btfnx wallets like this at the bottom

The rest is too many transfers out through dummy adresses in and out, so it takes lot of time
to track. I guess that is the idea

For those mining Burst right now, how is the wallet as far as stability goes? I beat my head against the wall for a few weeks last spring trying to get Burst working. My main issues were the wallet, with pools being rather wonky as well. Thankfully I got an excellent deal on the few HDDs I bought and was able to break even when reselling them.

I must have clicked lock on this last Night sorry about that.


here is a link to a new thread on a custom 16 gpu industrial style miner.

I will have one in the house soon.

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?

Most of my drives got plotted on my Ryzen 1700 gaming machine - usually while doing other stuff but NOT high end gaming on it.

[QuintLeo]

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.  


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.

I'm a bit suprised you don't just break down and put together a couple Backblaze boxes.

8-O

Supermicro makes good gear but they tend to be pri$$$$$ey - not so bad if you can find them used sometimes though.

[QuintLeo]

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.


For cpu once plotted it's already optimized.

The Seagate Expansion is typically one of their standard "compute" drives, the Archive external uses one of their standard Archive drives - BOTH work fine with BURST mining and tend to be the lowest price per GB most of the time.


Not all CPU plotters also optimize - I found that out the HARD way early on.
I'm not sure if ANY of the GPU plotters also optimize as I never got one to work.

Which pool do you use?

I never got the actual wallet to work, though I managed to get the "wallet server" working SOMEHOW at some point, and just access it with Chrome.

I THINK their wallet is coded specifically for Internet Explorer, from what I remember of the issues I had with TRYING to get it to work.


Pools - have been an issue for several months, lots of DDOSing going around, so I ended up reverting to solo mining the last few months.
Have any pools gotten STABLE in the last couple months?

[philipma1957]

Well I will not do the burst  looks lie quite a bit of work.

What is new on my end.

1 Evga  hybrid  1080 ti arrives  today along with a cpu waterblock as a bundle deal

That will bring me to  14 1080ti waterblocks

1 Hp Omen  pc with 2 1080tis shipped  today

That will get me to 3 of them  all with 2x 1080tis

So

14 1080ti water blocks
  6 1080 ti's  in omen pcs
  2 1080 tis in a 2 card pc build
  2 1080 tis in a 2 card open build -------- asus tubos one with a fan mod
  2 1080 tis in a 2 card open build -------- msi   aero    
  1  1080 ti zotac mini

27  1080tis  

and the biggest gpu miner ever  a loud mofo is due on tues  march the 6th !

not sure if I get this version with 2400 watt delta


Not sure if he sends this version with backplane for psus

"We have recently completed development of the 'Power Backplane' which will allow up to 5 x 1200/1500W Common Slot PSU's to be combined into a single power feed.  This is to support up to 16 x P102-100's, or higher wattage GPU's (300W TDP each) once they become available."

Most of my drives got plotted on my Ryzen 1700 gaming machine - usually while doing other stuff but NOT high end gaming on it.

Yes Ryzen 1700 work too. Both ryzen 1700 and i7 8700 do about 20k nounce/min plotting. But i7 do not need a gpu, abit cheaper.

For pools I use burst.cryptoguru 50-50 pool. Seems fine and payouts are coming daily.

I'm also exploring internal HDD solutions using cases from alibaba: https://www.alibaba.com/product-detail/huge-storage-4u-rack-36-bays_60604635903.html?spm=a2700.7724838.2017115.1.33bc1a1ewtr7mk

36 bay 4U server, one case, 36x 8tb drives. One case, one i7 8700 system and call it a day. Trust me, dealing with a hundred usb cables and a dozen usb hubs is like dealing with risers lol. If it costs 5-10% more but all all drives are internal via SAS at full read/write speeds and save a little more electricity it is worth it. Those usb hubs and power sockets costs add up.


Assume I can get this case for 500 USD shipped, add a $80 SAS card, it means 580/36 = $16.1 to connect each drive. Currently I use a $70pdu and $60 usb hub for 11 drives. I also save a ton of space, and that shelf is money too.

[KaydenC]

Which pool do you use?

I use burst cryptoguru 50-50 pool. For wallet Qbundle, I run a local node as the online wallets never work for me. It gets corrupted once a week and need to resync the blockchain, so I just sync overnight if I want transfer the next day. Not very convenient.

What a great idea, I just love HP DPS 1200 PSU's. 
They're robust and reasonably priced.

5 x 1200 = 6000  watts   which would do an entire   30 amp  240 volt  circuit   no need for a pdu  just an l6-30r socket and a cable to the backplane


It could do 16 1080tis  set to 80%  tdp

16  x 200 = 3200  watts     

load on the psus = 3200/6000 or 53.33%

load on the circuit  = 3200/7200 or  44.44%   you could use 20 amp  240 volt citcuits    which would be 3200/4800  or 66.7%  load

Have any pools gotten STABLE in the last couple months?

I tried numerous Burst pools back around mid-'17 due to all the DDOS attacks and finally got onto pool.burstmining.club and have been happy there ever since (about 6-7 months running).  The only reason i hesitated to go there in the first place was that many in the Burst community believed some of the owners of this pool were the ones launching at least some of those DDOS attacks. It was a bit strange that through that really rough period of time, this was one of the only pools up and running consistently, but finally I just gave in and joined where i could get the most return and stopped reading all of the in-fighting within the community.

For those of you still mining ETH... I've got a weird issue on 3 of my 4 6x470 rigs that Im hoping to get some advice on.

Seems like ever since the Window10 Fall Creators Update (i put it off as long as i could), I've been getting this strange behavior using Claymore 10.2. I also tried 10.5 & 10.6 but made it worse, so went back to 10.2.

Here's what happens:

- miner starts fine but in some cases after restarting, GPU0 starts running slower than all other 5 GPUs. Usually between 20-23 vs the 25-26 of the others

- it can run like this for a while, but then many times will eventually end up with a "GPU 0 hangs in open CL - miner restart".  Sometimes it does this reset every 30-60 minutes but sometimes it ends up doing it every couple of minutes, which of course kills mining returns

- since this is occurring consistently across 3 rigs and is always GPU 0 being the culprit, it seems very likely that this is a software issue and not hardware.

- I had a somewhat similar thing happen with Cryptonite miner... GPU0 was always way slower on all 4 rigs.  This was solved by manually designating the "-h" value for GPU0 in the .bat file, but there does not appear to be an "-h" option in ETH dual miner.

Does anyone have a suggestion on a setting tweak within Claymore to try to and fix this issue?

I don't have much advice for you.  I was having similar issues at one point with a 6 card rig I had on ETH.

My solution was two fold so I don't know what might have resolved the issue.

Solution was since my windows boxes are low resources, they didn't run 6 cards well.  So i switched to four card rigs.  I also tuned down some of the overclocking settings.

I suspect my issue was resolved more with not trying to run 6 cards on a low end windows PC.  More than likely in your case you have more available resources, as I was running some lean boxes.

If space is at a premium, a current-model Backblaze 4u rackmount case mounts 60 drives - abet it's a little longer than a "normal" 4u case, but it is specifically optimised for lots of drive throughput.
They use a Supermicro motherboard, should be able to upgrade the specified CPU to one with more cores *IF* needed to handle that many drives in a reasonable read timeframe.

What a great idea, I just love HP DPS 1200 PSU's.

Just FYI, if your using the HP common slot psu's like in the picture you can just daisy chain them together via the breakout boards now with the same black and yellow power cables...atleast this has worked flawless for me on all my HP model psu's, not sure about other versions....

Since i buy up used ebay server psu's for like $8-20 a pop, i try to run them at half or less the rate they are rated for, so my 1200watt units i run them around 600watts or less and such...

Every rig i have running on HP common slot PSU's with the breakout boards i have, i have them all daisy chained together.....so if one fails the extra one can take up the load, but you cant just throw them together and expect them to work well, you have to take the time to drill the hole in the case to access the voltage adjuster screw. When i setup a rig, i plug each server psu into a kill-a-watt meter, then i boot up the rig, adjust the voltage before loading up the rig so all 3 are the same according to volt meter (12.4v), then i start mining, i typically let it mine for 20 minutes to get everything nice and hot, then i come back and look at the kill-a-watt meters, typically from the start there will be 1 psu that is trying to do like 75-90% of the load of all the gpu's... while the others are just barely doing anywork, so i take my screw driver and adjust the voltage through the drilled hole i made carefully and adjust them all tell the watt meters on all of them are roughly equal load, thus they are all being used equally and let the rig mine typically overnight setup like this monitoring the load on each unit, typically i can spot a weak PSU this way due to the load drifting all over the place, so ill replace it with another used unit and if i can return it for my money back if the ebay sale has some sort of like 30 day warranty or something.. twice a weak PSU was only drifting because the fan on it was worn out and not working correctly, so i just bought replacement fan from china and those units are actually back in rigs doing work.

I can completely turn off any 1 of the 3 PSU's while the rig is mining and it will not skip a beat and continue mining shifting the load to the other psu's

I am looking at this design and awaiting it on tues next week.

I have 14 1080ti hybrids.

After I do a long review and test with enclosed 1060s

I may pull them and try it out with 14 hybrids 😀
