[Review] Spondoolies SP20E Jackson review by Starsoccer9

[starsoccer9]

Pre-Arrival

I would like to start by thanking Spondooliestech for giving me a unit to review as well as being so understanding for the delay in posting this review.

Day of Arrival

My SP20 arrived relatively quickly and was quite surprised by how nice it was packaged up compared to some BFL stuff I had received previously. I had 2 PSU already ready from previously using them on some Antminer S3's. 2 750Watt PSU so I figured powering the SP20 would be no problem. Sadly one of my PSU started acting up and turning its self off so I had to order a new/replacement for it.

Looking at the unit, it basically reminds me of a long antminer S3 or long BFL 60gh or 30gh unit, but with clearly more power.

Day of PSU replacement Arrival

After getting the replacement arriving yesterday I plugged it into The Sp20 and it worked flawlessly.

Here is a picture of the dashboard about an hour and a half in,

Below is the tempature as well as some more stats


I would say all in all the Unit is great and is running solid since putting the new PSU. The hardest part of the setup was getting the wireless repeater I had setup to work with my current network.

Summary

All in all the Sp20 is a solid unit with great down-clocking abilities

I see it is in a nice cold place.  and you got over 1600gh with out  being hot.  could you post a screen shot of this page.


it is the  asic stat page
I would like to see the readings on the loops at a high clock in a cold room 14c .

  my unit below  is clocked to 1221 and has low numbers 85c to 105c, but I have 8 units running and the room is 32c.

Sure here it is,

looks pretty much ideal. you could potentially squeeze another 20-30Gh from it if you went overboard on tweaking, but it would probably increase power draw by 30-40W doing so.

Sure here it is,

you are   near your top numbers.  temps are almost perfect for the high hash.

 I run the 8 and could not push the gear like you are doing. I would keep checking temps every 4 to 6 hours .

As long as only 1 or 2 are at 120 it is just okay. 

I would shoot for 115 max but I like  a safety margin.

Is there any problems running them at -20C?

[germanuniv]

This was a great review. Thank you for taking the time to make it.

[starsoccer9]

Glad you liked my review. I would say running at -20 shouldnt be a problem but you never know till you try.

Yea I figured since it is winter might as well let them get as much power as possible then come summer downclock.
