So you are saying four connectors pulling 300watts per for the sp20 is the the issue ?
I don't see how that could be the issue I think its either an issue with the firmware or the Asics themselves.
If a sp31 does 4.8 - 5 TH using the same chips at 2800 watts.
A sp20 should be able to do at least 1.8 TH using 1200 watts of power unless something is seriously goofed, since it is the same silicon basically.
If you are right and it is an issue of Maybe it is an issue of the SP20 needing to be able to pull a bit more juice say 330watts vs 300 thats a different issue I guess.
Either way 1650 TH is not good for 1200 Watts and that is what the majority of folks are seeing. I'm leaning to maybe canceling my order if this is something set in stone.

The rate, assuming all ASICs are operational, depends on the ASIC batch.
First batch of SP20 gave us ~1.8Th in cold temperature, but a lot of the units I see now are slower and provide something like 1.65Th. The ASICs behave as if they are from slow batch, I need to investigate why. The SP20 we produce now are faster - it looks (from the system tests in Flex) like they will provide 1.8+. We will have exact numbers soon.

Yes I think they did a design flaw since most current/watts sent on 4 connectors = 4 x 288 or 1152 watts. that is the max rating. so when you try to send 1200 watts over a 1152 rated connection you waste power. I

In my case I do not care about this issue since I plan to use 250 setting not the 288 setting. but any one wanting to send 288 or more is just wasting money.
I would love to see clear testing from some one that used an evga 1300 or an evga 1600 set at watts of 225 to 250.
I am pretty sure those will be the best watt to gh settings.

I am going to have a lot of fun with this gear in the underclock undervolt world should be fun for me. but if you are an oc dude/dudette this may be bad gear.

288w is the limit on the PCIx power connectors.
There are ways to override it in FW with flags, but don't do that (at least now).
We remember what happened to other ASIC mining company equipment when they pulled ~400W on those connectors.

got it.. i'm not tryin to burn my garage down even though it is detached. Well there has to be another to get better performance out of the sp20 at lower temps let me know what you guys find because I have two more on order in the next batch.

no there is not. four plugs = 288 x 4 or about 1152 watts which means use the egva 1300 g2 and use the cables with double headed plugs. just use the first plug .

I will place a photo. this is a design flaw in a sense if you are an oc freak. for me I am fine with it since I don't want to oc the gear. I will use the 250 setting. with my evga 1600 p2 and let the coins roll in.

double plug connection on the prisma. so my prisma was easy to send lots of power with no fear of hot cables. it just had other issues so I sent it to a DC

this is the cable from an evga 1600 p2 note the first plug (8 pin) has thicker wires then the extended plug it will handle close to 300 watts

pretty much the same experience I have here , one 800watt psu and one 1000watt psu. can't get it to hash over 1640 or so.

I do think there is a definite Firmware update that could fix it.... but the limits of the hardware would be stressed and probably fail.... I will show all the data as soon as I hear back from Spondoolies (it been a few days and I have not heard a peep)....

A single 1200 watt PSU seems to have been fried by the sp20 so sticking to two PSU's going forward. The sp20 cannot seem to pull enough juice from the rails to get better hash rates.

Then again 1.8 TH at 4x330 watts seems pretty the same as 1.6 TH at 4x290 watts my math is probably off as usuall.

If the firmware is fixed to allow the units to pull more than 288 watts we could probably get better hash rates I imagine.

ALso raising the voltages seems to cause major instabilities as well so maybe the fix is there /shrug

Hi guys.
I will release a new FW for SP20 that fixes the stability issue. Please stay tuned.
Regarding the overclocking, there are 2 limitations: 288 watt on connector and the temperature (on both ASICs and DC2DC).
In cold environment I think it can be pushed much higher then current limits, but let's get some experience with it running on the spec before you start pushing it further.

I am in a very cold enviroment front temp is 5c and back is maxed at 65 and 59 and i still cant push it past 1650 TH due to voltage/watt limitations on the firmware :stablity does not seem to be an issue in my case so I'm not sure if the new sp20 FW will be of help to me.

It's looking more certain that what we've been seeing in our DC is a poor reaction of SP30s to temperatures below about 6°C. We haven't seen any issues with SP10s yet at these temperatures.

Some machines work fine at low temperatures. I've seen a few operate just dandy at intake temperatures as low as 2°C. However, others will show problems at intake temperatures as high as 8°C.

When a machine has trouble at low temperatures, it's often specific ASICs that show the problem (often #2 and #17). It's not always the ASICs in the front that have issues, though it seems more common to be those. Once an ASIC has trouble at low temperatures, it sometimes has trouble even when warmed up. Sometimes it has to be disabled permanently; other times it can be enabled once the machine is warmer.

Indeed, but a hardware to be reliable, must handle 25°C variation without too much trouble.Here at low temperature some ASICs can't start. It will be a good idea to add a 'delay' option for the troublesome ASICs where they are turn off during the cold start and enabled later. Adding an option to change the Fan speed according to the intake temperature, will be a good too idea too. (I suspect this issue to trigger some machines crashes when minergate restart).

We're investigating.

Have you an update about this issue? Anyway, outside a software fix, if a decoupling capacitor fix (or modification) is helpful; it will ease running the machines, and will be welcome; An idea?

Version 2.5.19 is available for SP20 users.
It fixes instability in temperatures above 15C.
Especial Little Mermaid Edition, since today is (apparently) the international little mermaid day.
Hurray!

not a complaint in any way more of an engineering question. I just spent a week testing and using my asic miner prisma.

it has 8 jacks for power not 4. so how come these don't have 8 jacks for power?

I have one on order and don't mind a slight under clock rathe then the common overclocking many do on this site.

but if you had 8 jacks vs 4 you would have had a lot of overhead vs almost no overhead.

This won't be an issue for me as I am more interested in running this undervolted and underclocked using a platinum evga 1600 watt psu.

I am hoping to do 1000 watts and 1400gh. = .71 watts
or 1000 watts and 1350gh. = .74 watts

No choice but to host it. I had the same scenario with my SP10. I had the electric, but no matter where I was in the house, no matter what tricks I did, the noise was always going to be there.

Its not as bad as a SP10 or even a SP30 but its too loud for having in a living area.

I have luck swapping out the fans on an S4 with Scythe Ultra Kaze fans, they are about 130 cfm but in the Antminer S4 the temp stayed the same as a stock one I have running. I suspect a single Scythe replacing the rear stock fan and adding a fan on the front in a Push/Pull configuration would be a lot quieter and probably a bit cooler....

Wtf? your post contradict itself. Are you agreeing that their service is the best yet you're at the mercy of SP-T to help you with RMA?

No wonder this forum is a scammer's heaven. Getting bent over while saying "YES THANK YOU! "

Here is a new idea: You're a buyer, not a beggar.

It sucks. Customer's are afraid to complain or speak up for themselves. I always thought the seller has the duty to take care of the customer the best they can. Like the Dr. Oath.

A single 1200 watt PSU seems to have been fried by the sp20 so sticking to two PSU's going forward. The sp20 cannot seem to pull enough juice from the rails to get better hash rates.

Then again 1.8 TH at 4x330 watts seems pretty the same as 1.6 TH at 4x290 watts my math is probably off as usuall.

If the firmware is fixed to allow the units to pull more than 288 watts we could probably get better hash rates I imagine.

ALso raising the voltages seems to cause major instabilities as well so maybe the fix is there /shrug

"All clients getting their SP20s:

- Please set your PSU settings to match your PSU. The default value is low and will not give you beyond 1.3Th - it matches weak PSUs. Set it to 288 if you have strong PSU.

- SP20 are very sensitive to temperature. You should be able to get 1.8+Th in 10c, 1.7+Th in 20c and 1.6+Th in 30c (+- 5%). Do your best to cool the units."

My results are completely the opposite of the above statements from Spondoolies website...
-dual weak (750-700w range) PSU's appear to be way more stable than anything large and efficient. So far my best results have come from a pair of bronze rated PSU's over any combination of large platinum rated PSU's.
-I have yet to reach 1.8 and have run the machine in temps from 0c to 25c, right now its in a 5c climate and cranked up to 288 running 1.6-1.625....
