A Prisma cost 1.47 BTC or $579, an SP20 cost over $900 with shipping. The SP20 is $258 away from being the same cost of 2x 1.4T Prismas.

My  sp20 cost  197 usd more then my asic miner prisma.  I over paid for the  prisma as I used paypal.

 I like the prisma but I don't think I can run it when I am out of my home.
 I have a sick relative and spend 2 days at a time with him in NY about 80 miles from my NJ house.   
 I tried to downclock the prisma to use low power when it is unattended and I have found that no matter how low I clock it. It uses 1000 watts.
 So at freq 210 it hashs at 1000 gh and uses 1000 watts or 1 watt per gh  not good.
 So I bumped it back up to freq 240 I get 1400gh and 1245 watts. or about .889 watts per gh

  I can tell I do not want to run it if I am not home for 2 days or so.  This is going to be the case for the next 3 months.
  If it would scale down and use 890 or 880 watts when down clocked to freq 210 hashing at 1000gh I would keep it.

The sp20 should be safer to leave unattended.
The sp20 should be able to downclock and not use more power per gh.
If I leave it unattended and it scales down at 1000gh I am looking at 640 watts. vs 1000 for the asic miner

Since my price difference is 197 usd.  I think I can make up the price in the long run.

If you expecting an SP20 to be any quieter then you are going to be seriously disappointed. Try reading what people have said about the noise out of them. Also, if you're worried about your house burning down while you are not there then I have to ask, did you not see all the pictures in this thread of the mining farm that burned down?

  Yeah I saw  a burnt up sp30 farm overseas  and what does a 5mw farm have to do with a  3-5kw garage setup.

but from these photos you need to use real caution with a prisma


Problem board (107.9C temp):


Working board: (50.5C temp)









I have a location that is good for the sp20 but was not acceptable for the asic miner prisma.
The casing will allow me to address the noise issue


I would have kept both but the inability to downclock the prisma  correctly held me back.
the downclocks would drift up in thermals and watts.

 I could not get it to stay at 1150gh and 900 watts. I could not get it to stay under 1000 watts for any length of time on any down clocked frequency.

 

 I am hoping to finally get a hold of a spondoolies and have a bit of fun with it.

I have just put up a website to review Miners called www.cryptominerreviews.com, with the purpose being to make real world measurements of temp, voltage, overlocking stability testing etc.  I recently bought an SP20 to do my first review on and hope to have it posted shortly.  I plan to follow up with an Antminer S4.  I have uncovered a lot of issues with the unit, some of which I think Spondoolies has at least reported but offered little in the way of resolving the issue.  One such issue is the PSU choice, which can not only cause boards to show up as "dead" but also have an impact on the hash rate of the machine.  I have tested with multiple single and double PSU setups and found that single rail high efficiency PSU's tend to cause more instability than less efficient smaller PSU's (cheaper)....also there are still firmware issues, if your machine is bricked or showing dead boards, reverting to 2.5.10 then letting the machine warm up with voltage set at 288 then updating to 2.5.12 worked best for me.  I considered leaving it at 2.5.10 but the hashrate was all over the place....cheers...keith

[kilo17]

also, the only way I know of to get 2.5.10 is from the Firmware recovery process with an SD card on Spondoolies website...may be helpful to have that as an option on the Manual Firmware Update.

"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....

I have emailed Spondoolies but have not recieved a response....cheers...keith

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.

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

Does anybody have an inexpensive solution to SP-20 noise?
My house does not have a basement, so noise reduction or elimination is a must.
Thanks.

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.

Guy,

Thanks for you and your team on taking care of my general issues (from SP31 RMA's to SP30's running in your DC).
SPTech product and service is exemplary and unmatched.  

Sincerely,
Miner454

Agreed, best customer support in the business.  

Shame everything is out of stock tho

Guy,
I have to agree with the above comments, though I have yet to hear from Katya regarding the forms required to RMA my damaged SP20.  
I did contact support at which point Barbara informed me that Katya would get in touch with me regarding the aforementioned.
A week has passed since I sent my initial request to the support team, I also sent a follow up email, though no reply yet.
Thank you,
Ski

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.

Its generally the opposite. Customers rarely praise for good service and often are vociferous regarding poor service.

No company is 100% perfect, especially smaller companies such as this one, but these guys, in my experience, and I've purchased from just about everyone legit, are the best I've experienced not just in this business but in many others as well.

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....

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.

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.

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

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?

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.

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.
