Topic: Spondoolies SP30 Loop Errors ? (Read 754 times)

When u re thermalled the chips did u clean the Asics up with isopropyl alcohol and scrape the hard shit from around the decoupling caps next to the Asics?
When I rebuilt my SP20's the first one I did had this issue.
I then re did the process but cut the glue from the PCB using a hacksaw blade so the heat sink went closer to the chip.
You unfortunately need to use a shit load of paste (ignore anything you read on the internet).
I put the heat sinks back on and tightened the clips, put a length of wood over the heat sinks and put a decent weight on there. I use epoxy and glued the heat sinks closer to the board and left over night.

This fixed the issue with a hash card so I did the same on all of them.
I know the SP30 is a bigger machine but I'm sure the guts are the same just different PCB layout.

Well, this miner was used in mineral oil so basically all the paste came right off with ease. I am eventually going to do the same thing and submerged it in mineral oil but I wanted to fully configure it and get it running 100 percent before I drop it in the oil. I would hate to have it in the oil and then have to pull it out to fix/change something. What a mess. It did use a crap load of paste. I honestly don't like the spring loaded heat sinks. I would prefer they were tight against the chips. I might consider gluing them. I'm not worried about the need to remove the heat sinks again. This will probably be the last run for these units as the difficulty will be to high in the next couple of months for these to make any money...

Thanks for your help !!

Thanks man ! yes, I have the latest Firmware running. I just found the location to disable loops. Didn't know that was possible. There are 3 disable options per loop. Do I disable all 3 or ? Also, by disabling them, what gets affected ?

My temp is at 51c or 123f. Fan speed at 100. How can I get it to run cooler ? It's in a room where the air temp is about 60 degrees so it's not that hot...

Thank you !!

Go into the settings and disable loop 3. Also check your temps and make sure you are below 120 temp. I think that 125 is the limit to where its cuts off.
Have you updated the firmware to 2.7.1? I think that its the latest and available on the spondoolies Bitcointalk thread.
I have found for them to run continuous without stopping you need to bypass or disable bad loops, and up the fan speed and, or throttle back loops to keep them 100 to 115 temp.
 

Hey guys. I picked up 2 Spondoolies SP30's the other day. After taking them apart, cleaning them and adding new thermal paste, one unit is giving me an issue. It will run and hash for about 30-40 minutes and then shuts down. It will eventually start up again but then shuts down again. Sometimes after minutes, sometimes it runs much longer. Anyway, I was wondering if one of you guys can take a look at the System Log and see why. The only thing I noticed was loop error 3, which was in yellow text. I have copied and pasted those errors bellow. If you want the entire log, please let me know:

Nov  2 23:36:09 miner local1.warn minergate[29509]:  ASICS in loop 1: 3

Nov  2 23:36:09 miner local1.warn minergate[29509]: Critical: Bad loop 3 = set loop as disabled

As you can see, there seems to be an issue with loop 3. Whatever that means ? LOL. Any recommendations on how to fix if fixable would be greatly appreciated !!!

Many thanks !!!
