My new SP31 miner arrived today, very pleased with the performance, thanks Spondoolies!
fired it up on default settings and it seems just as, if not more stable than my old SP10's.

You can probably increase the power on those PSUs quite a bit. 1275 is pretty conservative. 1330W is about 90% likely to work without problems. If those are Emersons, I'd set it to 1350W and let it learn its limits. There's a good chance that 1350W will be below the limits, actually. Doing this will give you as much as 150W more power and possibly 200GH/s more hashrate.

Also, at those temperatures, I find that the optimal fan speed is 70. The temperature at which 70 and 80 are equivalent is about 16°C for SP30s and SP31s. Higher fan speeds use power that could be supplied to the ASICs, so too high a fan setting actually reduces performance slightly. The SP35, SP10, and SP20 are more temperature sensitive than the SP30 and SP31, so they should usually be run with higher fan speeds when performance maximization is the goal. If you don't increase the power to 1330W or 1350W, then the optimal fan speed is even lower. At 1275W and 11C, you might be best off at 60.

thanks for that, i'll look into it today when i go up to see my mum 

so, i cranked it up a little. now running 4850GH/s (immaculately stable at that rate) and pulling only 0.55w/GH.
i'll run it at that until I get a chance to take it to the unit with my SP10's - that's 400 miles away so hopefully i can manage to get there at some point before new year... very happy with these miners. The SP31 is indeed like the big brother of SP10, just as stable with a much higher hashrate and superbly efficient.

well done on another fabulous product.

Can someone do a sound meter check on their SP20 in their home? Not in a garage or warehouse? I'm trying to figure out the acoustic situation they will bring down on me and figuring ways to avoid that if I bite. Here's one of my AntMiner C1's hashing 1005TH/s. I actually have two in the same room and don't notice they are there, but of course rather have Spondoolie's if the prices are right.

Thanks.


I was about a foot away or less when doing this measurement.

Thats at 80% fan.

So well within the +/-5% spec. Anyone managed to get an sp31 past 4.9th?

What's the actual difference between the sp31 and sp35? Number of chips, dc/dc regulators, or something else entirely?

[Hunger]

Wondering about SP20:


Inside SP20 box are two PCB, is there possibility for have only one core plate running? by connecting psu to only one them?

Nope, 4.7th here ... the +/- 10% rule ... machines vary.

If your wanting to have lower power you can underclock to a amazing level with SP20.  I am unsure why you would want to run only one side though.

I believe so.  I had to RMA one of the first SP20's due to the board sliding loose during shipping.  One of the boards had a cracked VRM.  I tested the other board by itself - unplugged the "bad" board completely. It worked just fine, of course at half the hash speed.
Not condoning doing so, just my experience with running one board.

Maybe he has got a not so powerful psu with only 2 6pin connectors...

Anyone who did some underclocking on sp30? max wattage for me would be 2800w but i preffer 2500w

Got bad wiring!

Why would someone buy an SP20 and not have the proper PSU waiting? If not, just order a PSU from NewEgg or Amazon and have it in two days.

[mavericklm]

I couldn't wait

Anyone want to see a 360 of the SP20? I've got these in 4k, but I don't think anyone's internet would appreciate 170mb. Hard as hell to balance lighting on a silver, shiny case - and ignore the floor shadows that didn't come out right, I'll remove them at some point.

What's the actual difference between the sp31 and sp35? Number of chips, dc/dc regulators, or something else entirely?

The SP31 contains two 1200W power supplies, which are run (with the PSU manufacturer's approval) at around 1330W of 12V DC output. The SP35 uses 1600W power supplies instead. The SP30 was identical to the SP31 except that it used ASICs from a different batch that were significantly slower and less efficient due to differences in silicon doping during wafer fabrication.

It appears there is a bug that affects SP35 PSUs. The PSUs appear to not notify the mining software properly when they encounter trouble (such as overloading), which results in the mining software not reinitializing that PSU. When this happens, one PSU and one hashboard will sit idle until the user manually restarts minergate. Zvisha is aware of this issue now, and will probably have a firmware fix for us soon. If you have received an SP35, I suggest checking on it frequently for the next few days. It might also be a good idea to drop the PSU limits by 50 watts until a fix is released.

Our units have this as well. Can confirm dropping PSU wattage fixes it.

so under-clocking just a little lower then 1266 watts for 2 sp20's would allow me to  run all those evga's with 2sp20 each.


so I know the sp30/31 can do lower freq then  750 can these sp20's go as low ?  Is this under clock safe?

I have a couple of 1300W EVGA PSUs too. If you can manage to run 2 SP20s on one PSU I would consider getting 2 so keep us updated.

yeah it is a piece of cake on the more costly 1600 p2

I am going to run the 1600 p2 at the 1266 watt 2400gh and low asic freq overnight.

 if I am good to go I will test the 1600 p2 at a lower setting  from 7am to 7pm tomorrow.

if it still works I will then do the 1300 g2 with 2 sp20's

My EVGA 1300 just died after 4 days with a SP20. Luckily the SP20 made it ok.

Sorry to hear about the loss of a PSU.  I have a EVGA 1300 running on one as well.  Mine is working great no problems.   I would contact EVGA hopefully they can get you a RMA quickly.

Got bad wiring!

EDIT: oops, its early, i thought i read SP31...

stock settings are 2500w ( 2 x 1250 )

on initial power up I was getting ~4700 @ 0.53w/GH
i've cranked it up slightly and now have ~4850 @ 0.55w/GH

you can always underclock it by lowering the max wattage cap.

I think it was just a bad unit. Ill get it sorted soon!

meh. i'm a dolt - but your post has instigated me to double check all my PSU's
been running an SP20 on an EVGA 1600 80+ gold but using only one double headed PCI-e cable.
swapping it today for two single headed PCI-e cables before it melts.

i really should have more attention to detail with my miners.
