My SP20 went non-responding yesterday after I added a couple of pools. The web admin GUI never came back after submitting the change, and I could not ssh into the device. It responded to pings, but that was it.

I power cycled the unit and attempted further edits to the pool list. It seemed to work for a little while, then the SP20 hung again.

Operating on a guess that maybe I had specified too many pools, I rebooted again so that I could remove some. Once I saw pings responding, I quickly fired up the web admin GUI and stopped the miner. This allowed me to get back to the pool list and remove a few. Since doing that, the SP20 has run reliably again.

Is there a known problem with too many pools? I had 9 pools specified at the time that the machine went non-responding. I know that's a stupid large number of pools, but I've just been moving disused pools to the bottom of the list with the thinking that if I needed them again, I could just change the order.

If the miner craps out after too many pools are defined, then the UI should probably limit the number that you can specify.

Note that this was with the v2.5.52 firmware.

I have experienced similar behavior from some of my SP20s. Only for me, it was if I made a number of additions or changes on the pool page. So for example, if I added a pool and then did a lot of shuffling of the order or added a bunch of pools at once, the system would sometimes hang. My way around it was to enter a pool, hit submit, navigate to the status page, go back to the pool page and make the next adjustment. I noticed that I could safely make two or three changes to pool order before I experienced a problem. Once I started operating like that, I didn't experience the problem again. Firmware has been upgraded a few times since then and I have not tried it under the latest releases.

Is it possible to get a list of pools you are using. From my several tests, I couldn't reproduce the problem trying pretty big numbers
Except memory consumption that is required for each pool, there is no limit right now in SW

^This is really making a big issue over pulling an extra 50GH out of a unit - a value of less than $18. voiding warranty or buying a second $20 fan and spending the time to install it is not worth it.

At the peak speeds, any improvements you make come at the cost of about 1-1.2W/GH. Running at 1500GH uses approx 210W less than running at 1700GH. Unless you have very cheap power it will likely make sense by summertime to throttle back the hardware to improve the overall efficiency - or have heat problems.

I personally have 3 arriving this week that I hope to achieve ~1400GH/800W so that the fan can be kept at a reasonable volume. At $0.15/kwh it doesnt make much sense for me to try and get another 300GH/400W out of the unit, as the added hashrate gains are entirely spent on added power draw. Same reason as Ive throttled my SP10 units from 1400Gh to 1260GH to save 200W

Sorry @knlondike but you misunderstood me.

You calculate with a fix price of the machine.

Calculate cost and profit.

I'm not speeking about the only 50ghs but when the weather gets warmer this will be 100ghs (from 1680 ghs) or more.

At 20 pieces it's 2000ghs....

And i have room much more than 20....

I hope you unerstand why i'm trying to find some solution.....

curious what you pay for power. I understand the aspect of clocking hardware to its limit if its profitable, but if you need to make >$10 in modifications to gain 50GH/60W per unit, plus have slightly more PSUs/TH it could be more practical to buy an extra SP20 for that extra 1.65TH/$500. If its a hobby to do modifications though thats another story

Ok I'll give up...

For me it's not hobby... It was a hobby with a Jupiter and some S1-s.

Maybe would be practical to buy one more unit for sure. But I have a lot of high cfm fans and other parts laying around....

But at this point I give up. You don't know a lot of details so you can't make a judgement what am i do and why. But trust me, I have the reasons.

So back to the original question.

Any ideas to improve the cooling? Grin

Very strange, was a profitable hobby when the Jupiter and S1 were profitable, now the sp series are not. So now is unprofitable hobby/business

Really all of this should go in another topic. But...

I don't agree saying SP gear is not profitable. They have so many different miners, there is no one size fits all on calculations. I have ROI'ed almost every miner I have had. You need cheap electricity, run as long as you can. With SP20 you have a heck of a under clock theses will be running for quite a while. At end sell to someone with "free" or even cheaper electricity. If you keep PSU's you can go to another generation without some of the upfront costs.

Sp gear is profitable, I didn't said it's not.

The others well said by Notlist3d.

There was no power to the DC2DC at time of miner_gate_arm start. My primary suspicion would be that the PSU was off, the connector was not inserted properly or the shortcut on the PSU motherboard connection was not good. Please try to make sure the PSU is running and the connectors are good, try to boot the units in bad configuration again and if you still get the problem send me logs (from webUI->"Settings tab"->"Get Logs"). Send to my mail "zvi@spond..." with reference to this post.

Thanks for the reply Zvi, as they working fine now now with the mixed PSUs I'm not going to mess with them, but I did ensure cables were connected properly and the same PSUs are working fine on other gear now...

I have experienced the same problem with an Antec 850; I think the sp20 overdrives it, the power protection cuts in; after 5 minutes it resets and starts again at a slightly lower rate.

Does the SP20 do adaptive power management?

Looking for some SP20 help; things I've tried:

Restart
Upgrade firmware
Swap PSUs

They are running on 2x EVGA 750W PSUs each:

...

On both machines only one board is hashing out of the two.

In the first pic one the second board is hashing, in the second pic the first board is hashing.

Focus on one at a time, if you swap the PSU's to the dead boards sockets does it come up?

Swap PSUs and take another screen shot.

Here is a little bit of bizarre for you:
All 4 PSUs on the 2 SP20s were EVGA 750 Watt (all tested and working), swapped the two ones that were on the non-running boards with corsair 650 watt and everything seems to be up and running fine...
So each SP20 has 1x EVGA 750 + 1x Corsair 650, and works.
The 2 EVGA 750s that were not working on the SP20s are now powering other miners just fine...

Yeah, I usually have 117-122V, but even with 110V I thought that 15A outlets (typical for US) are rated for constant 13A, hence 13X110=1440W

Go with 80% for continuous operation. 15A x .8 = 12A x 110V = 1320W or 12A x 120V = 1440W.

Sorry misread it. I've thinked the pictures about one machine before and after he swapped the psu-s.

This way Biffa has the truth, try to put the 2 psu-s from the 2 working blades to one machine and check it.

Improving is easy.
Good polish aluminum heatsink and the cooper block to mirror look, then put some good thermal paste, then put more powerful fan...

At the peak speeds, any improvements you make come at the cost of about 1-1.2W/GH. Running at 1500GH uses approx 210W less than running at 1700GH. Unless you have very cheap power it will likely make sense by summertime to throttle back the hardware to improve the overall efficiency - or have heat problems.

I personally have 3 arriving this week that I hope to achieve ~1400GH/800W so that the fan can be kept at a reasonable volume. At $0.15/kwh it doesnt make much sense for me to try and get another 300GH/400W out of the unit, as the added hashrate gains are entirely spent on added power draw. Same reason as Ive throttled my SP10 units from 1400Gh to 1260GH to save 200W

Sorry @knlondike but you misunderstood me.

You calculate with a fix price of the machine.

Calculate cost and profit.

I'm not speeking about the only 50ghs but when the weather gets warmer this will be 100ghs (from 1680 ghs) or more.

At 20 pieces it's 2000ghs....

And i have room much more than 20....

I hope you unerstand why i'm trying to find some solution.....

curious what you pay for power. I understand the aspect of clocking hardware to its limit if its profitable, but if you need to make >$10 in modifications to gain 50GH/60W per unit, plus have slightly more PSUs/TH it could be more practical to buy an extra SP20 for that extra 1.65TH/$500. If its a hobby to do modifications though thats another story

Ok I'll give up...

For me it's not hobby... It was a hobby with a Jupiter and some S1-s.

Maybe would be practical to buy one more unit for sure. But I have a lot of high cfm fans and other parts laying around....

But at this point I give up. You don't know a lot of details so you can't make a judgement what am i do and why. But trust me, I have the reasons.

So back to the original question.

Any ideas to improve the cooling? Grin

Do you live in a winter climate? do you have a home? can you get cold air to flow from outside to the intake on the miners.

open a window put box fans in the window blow in cold air to the intake of the miners then open a second window let the hot air blow out.

you would need 2 windows and a room with a shut door to do this build a pair of vents to direct the air. you say you have 20 of these

so they stack 5 high make a 4 by 5 stack of them direct the cold air in and the hot air out.

I would like to find a solution to each machines.

It's winter here now but I have to figure out something for the summer too....
