Shopping for  SP20E's - Is there a way to determine from the Serial Number that it is really an 'E' and not a plain SP20?  All of my SP20E's start with 'FL145xx" so I assume numbers higher than that are 'E's".  Does this make sense ?  Who has a really early 'E' machine that they could check ? 

OT: Does anyone remember 'E-Machine' computers, $299 desktops what a POS Smiley

I normally use seeing if it says Jackson to tell, but I'm betting your right about a serial number difference.

On the OT:
Yes I do remember those E-Machines.  They promised never obsolete... i mean how could a E-machine be obsolete they had AOL on that thing!

Pic of never obsolete sticker they had: http://www.halfdone.com/Personal/Job/Pictures/ScrewUps/Never_obsolete_emachine.jpg (Did not do as image as it was to big and annoying for thread)

I have 3 of these SP20E starting with FL1448... so I suggest you do as notlist3d pointed.

The electronics plate must be covered with a protective lacquer coating.
Conformal coating seems a bit overkill for a product that's not intended to be used in volatile environments.

Agreed, never mind the fact that these devices will likely produce less income than the power they burn in less than a year.

I've fixed hundred of the new LG electronics that were damaged in sea water. Usually only needed replacing electrolytic capacitors.
That was five years ago, and many of them are working today.

Are you saying it was sea water that got into your miner?  I guess that would explain it if so

And holy crap that looked bad.  Do you know how the water got into miner?

I'm sorry for your loss.

Soooo here my experience with the RMA.

First, if you don't run your machine in a perfect condition (Not like me cracking a window so the intake got fresh air), you might want to think 2 time before sending your machine back. BTW, my other machine was next to this one and it's still run rock solid. (1654gh) So I guess that was a bit of bad luck ...

So as I was using my SP20E close to a cracked windows and they found some corrosion near a capacitor. Also dust (because I didn't want to open it to void the warranty) and it's not under warranty because of the corrosion. Both ASIC 0 and 4 on each blade (which are the first one next to intake) are in bad shape.

Asking 200$ (105$ shipping and 95$ for the diagnose) for the exact same machine.

Asking 250$ per board to replace them plus the 200$ us.

Sooooo next time you run one of those close to a windows. You should keep it home I guess. Open it yourself, have a look or find a electronic specialist to have a look. It will save you time and you machine.

If I knew, I would simply disable the Asic and keep like this ...

but now for 200$ us ?

Not even sure it worth to get it back ...

Hi HerbPean,

We're very sorry to hear you are unhappy with the service you are getting.

The unit at hand has experienced massive corrosion as can be seen in the images below:

These are just a few examples, there's extensive rust and corrosion damage across the boards. This damage can only be caused by exposure to either extreme low temperatures, very high humidity, or both.

The unit has been damaged so badly it can only be fixed by replacing the boards.

We take pride of the quality of our units and service yet even our units have their limit, just like any other electronic device.

Our customer service has RMA several units as I'm sure the forum members can verify, however we cannot cover damages that are caused by improper maintenance.

Our team will continue to work with you as best they can to help you out and will be happy to continue doing so in the future.

Regards,

Gadi


Gadi,

Looks like you guys think I want my unit to be under warranty. This is not the case...

My entire point was : Guys with my "RMA experience is" ... make sure you have a unit not running in the same condition as me before sending it for an RMA.

My entire unhappiness is about the two options on the table.

1. 200$ for getting your unit back as is.
2. Pay 500$ for 2 new blades plus 200$.

That is what I shared with the community.

so you shipped the entire unit for the RMA? IMO/IME, basic home diagnostics are usually required related to bitcoin miners. If it was a single bad board, shipping just that board for repair/replacement without having to ship the rest of the unit would allow you to continue mining with 1/2 the SP20 and drastically reduce shipping weight/cost

I did that way back when a Bitmain S1 stopped hashing on one board. pulled just the board off the frame, mailed it to them, got back a brand new hashboard that i pasted and re-installed.

Bitcoin isnt mainstream enough that the RMA/DOA process is smooth - being able to do modular components and repairs is crucial.  (I look forwards to the SP100 having boards that can be removed with no more difficulty than in the SP20 or antminer S2 - it would make RMA simpler)
----> on a related note, i have a few SP3x units in various states of 'angst', and when looking under the hood its pretty clear that the SP3x series is not easily repaired - there are a LOT of different components and screws that lock the hashing boards in place, and thus make RMA of a single bad board nearly impossible (same with trying to frankenstein a pair of half-working units into a singular 100% unit)

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461

I totally agree, that would have been the best option, I didn't do it since I was scare the warranty would have be denied because of that. I could also have clean all the boards of all the dust prior to the shipment ...

Anyway, lesson learned.

Wait so are you accepting the loss here? and not doing the RMA process?

Thats just money loss out the door on some production level not your fault right.. so why not do the RMA?


Edit: nevermind, just read the cost of RMA.. what the hell. is there a way to still sell this though on ebay and breaking even though? if it still mines of course, but under several conditions. so then it wouldnt be much of a loss?

It's not like i'm not going to eat for the next week, but yes it's a lost ;-)

I would gladly bring it back home ... does it really worth it ?

2 ASIC down (in fact one is still running at min speed ...) is about a 400 GH/s lost at full speed. Not really a big deal. So i assume around 1100 at most.

What is the true nature of this foundation? What are they really responsible for? Most foundations in my opinion are corrupt and the top hierarchy usually takes money from the foundation's accounts anyway for their own personal use. This is nothing new. Happens every day in my own government all over the US. And I thought that the bitcoin community votes and makes the laws, not the foundation?

It was suppose to be a foundation of a lot of the big names in bitcoin.  To help bitcoin grow.

But most people who are respected have left the group.  At one time saying our company was a member of the foundation meant something (they paid the foundation so much for some levels).  But in the end it was executed horribly in my opinion.

Cold air in and of itself isn't bad. I duct in cold outside air (down to -40C) and have never had an issue with corrosion. Even at 100% RH, extremely cold air has a miniscule amount of moisture in it and the RH will quickly drop as temperature rises. There's the same amount of actual water in a cubic meter of -20C air at 100%RH as there is in 0C air at 20%RH, so you won't see condensation just from the air. What can cause issues are
1. Drawing in water, in the form of snow/rain.
2. Things not running. Blowing moist air over a running miner isn't really an issue as the heat from the miner will prevent any moisture buildup. If the thing is not on (or worse, if it is on but not running or generating any substantial heat) it can have moisture buildup.
3. Running them inside a warm (possibly humidified) house. Combine this with #2 above, but if you keep your house at 20C/50%RH the dew point is ~10C. You won't get moisture buildup on a miner while it's working, but it can if the miner cools down below that temperature from cold outside air and then stops running. Running electronics below ambient is always a bit of a risk and needs to be planned around.

OT: Does anyone remember 'E-Machine' computers, $299 desktops what a POS Smiley
I still have one working almost continuously since 2003/2004. Around 2012/2013 I tried to order replacement parts (mechanical,cracked plastic) and I found out that many places are still using it. Gateway may be still providing support for them.

Runs Bitcoin & Litecoin just fine, although mine was way more expensive.

I love E-machines, and their predecessor, Packard-bell.

They were cheap, nasty pieces of slap-dash assembly that usually got thrown in the dumpster by about the end of six months, wherein I retrieved them and used the components for various frankenstein builds Cheesy Still have several of them lying about, all working (when i want them to). Out of the box they were essentially worthless. Out of the dumpster? Priceless!

Packard Bell wasn't the predecessor of E-Machines. They both ended up getting bought by Acer after Gateway bought E-Machines, but Packard was bought after Gateway.

 Dear Edgar,

I just spoke with Zvi and he said that you spoke with him. Zvi was not aware that we had tested the board carefully before we sent it to you and we know it is working. Please do not send the board back.

The only reason the board may not be working is if it is not installed correctly.

If you need assistance installing the board please let me know.

Regards,
Barbara



Finally received an RMA SP20E board (unfortunately it arrived dead/DOA)

Refuses to accept its DOA

Apparently it is working and i am just doing it wrong... despite having already tested the dead board and replaced it with a non dead one.


DOA board is DOA - not sure what else i can say.
