Topic: BM1384 Pod Miner plus trade-in/recycling - an interest and feasibility poll - page 5. (Read 27904 times)

I sent in the dead avalon6 board

would be interesting to know what killed it off and if the chips can be used for something like a pod .  most of the chips look good.


 

Sounds like something similar happened to my S5+ blade.  I'm not sure what happened really but there was a heat sink that fell off and it still had the chip attached to the heat sink.  I think one or two heat sinks fell off and then the extra heat generated somehow caused some kind of chain reaction. 



I can understand that the bitfury chips would be the way to go, but if for any reason you want this board just let me know and I'll ship it over to you.  I love the idea of a modular miner.

Right now I don't want any S5/S5+ boards. I'll take stock of what I got here in the next week or so and see what I got going on. In the next week I'll probably be starting gathering the remainder of Compac parts and also putting up some Pod news. I was gonna bust out some rafflable Pods today but cavalier came by for some repairs and such which burned up the whole afternoon. And since it's Friday, my afternoons are short anyway because cheeseburgers. But next week I'll have a better bead on what ASICs I'll need for Compac batching and any Pod batching we end up doing with BM1384. When I need boards, I'll make it known.

I have an S7 in hosting (Batch 1 I believe) that blew a board when I first fired it up. This particular machine had been sold on eBay and returned a month later with basically nothing on it working. Owner replaced two boards already before it got to me. I replaced a fan and sent the third board in for RMA. The replacement just arrived, and when I installed it one of the chips exploded. Literally exploded. Blew the heatsink completely off the top, with a little rectangle of IC packaging still stuck to the tape. So that's fun.

If you look back to the first post in our BM1384 dev thread, you'll see a description of what we wanted to do for mining boards. The idea, originally, was to make a quarter-S1 board (so, half an S1 blade which puts four to an S1 chassis) which could operate on its own with a decent heatsink and 120mm fan, or four at a time on an S1 chassis as a decent full-scale miner. The idea has shifted around a bit to larger boards and a discrete pod design, but I'm really leaning back to the single quarter-S1 board as a single product which, depending on mechanicals, can fit two or three market sectors. If we end up with, say, Bitfury chips or something on that power scale, we could make an S1 into 4TH or so and if one board blew you'd still have 3TH of miner. If the controller shoots craps, well, the boards are USB-connected so just cable them to another controller without needing special hardware. Modularity may cost a little more, but it does rule out and/or reduce a lot of potential failures.

yea but by blowing a cap could have done more damage then just the cap so would be better for somebody to look at the board that knows more then the adverage person to see if that is the only problem ... btw thanks again sidehack for fixing my undervolted s1 / my underclocked s2 and also looking at my compacs they are working flawless now

Looks like just a bad cap?

Are you still looking for S5+ boards?  I may have a bad S5+ board as well.

WTF does this have to do with sidehack?

He will be getting this.  Have some fun sidehack

Will do. So far been 7hrs since I directly contacted Bitmain and got an auto reply saying they got the msg. My initial contact to Zendesk explaining the tests I did was answered within an hour. They said time to contact Bitmain. fun fun fun

Even though just 1 bad board out of 11 s7 ain't bad, if BTC goes up a bit more I prolly should get a b9 just for spares...

In a way, this points to the biggest disadvantage to high TH/s per miner such as the s7 or BitFury's supposed 20TH/s rig vs things like a pharm of Pod's or stick miners. Sure takes up more space but for Home miners or small to moderate sized miners like me (and 1 year ago I never ever would have called ~70TH/s total 'moderate') if a miner goes down you don't immediately drop 4.7 THs or more of hashing.

Midwest is not the greatest on weather right now.  But I would agree delivery companies seem to love day's they can claim as weather.  Slap a banner on website it gives them reason not to be on time.

Let us know if they end up letting you send just the dead board.  I'm guessing they would want entire miner,  but that would be nice if they let you just do blade.   

Yeah, they reported it was stuck due to weather but probably because they are babies.

Hmm. UPS kept reporting it was stuck in St. Louis due to weather.
Anywho - Merry late Xmas! I see I forgot the 4 s1 boards from the 2 s1>s3 miners. If ya want them for buck parts I'll send them with the hosted miners next week. One of the new s7's that is replacing them here has one blade DOA so am seeing if Bitmain will let me send just the 1 dead board in RMA...

Storms in my area? It's been depressingly un-stormy here lately. We've got a three-day-old dusting of sleet still clinging to the ground and that's it. Also, stuff was delivered about half an hour ago.

Once the snow from the storms in your area is cleared so UPS can deliver you will have 3 s5's in the load of donations I sent ya
-Cheers!

My old S1 is boxed up and ready to ship to you for trade in parts, sounds like we might be getting closer!  I'm looking forward to this pod since my last U3 died a couple weeks ago.

So no pods will be going out? Well damn if not, I would of loved to mess with it like to compac. I have an old thermal-take water cooling loop for a 775 cpu I could of thrown on there and took it to the max. I have a spare s5 controller setup you could borrow for a while, I may end up using it for a project down the road. I saw you had 1384 breakout boards somewhere in the thread, any chance you have some to sell so I can at least use these pulled chips laying around?

Well, I found a bit of time today to try and repeat refinements on the Pod. Well, I found time to start it. Got the robot warm room and the machine recalibrated, tweaked the placement program a bit. Tomorrow's a short day and probably full of hosting tasks, but I'll try and find time to rig up the second new pod board. If it's going well, I'll see about splicing together some more adapter cabling and run two or all three test pods to the S5 controller I have working. And then post pictures.

I have been unable to locate my third S5 controller. Pretty sure I have one somewhere. Anyone got some extra S5 controllers?

Also, since the prototype pod is probably the last thing I'll do with BM1384, I'll probably start a new thread at some point since the old BM1384 Project Dev thread will be kinda defunct. But I may be working with new stuff sometime soon so when I have something worth saying I'll start a fresh thread to say it.

A: slightly drunk, made reading 10x harder..
A2: I'm used to 2-5 sentences per chunk of text, aka paragraph (you had 13 odd), it just me, I'll continue to do my trick, Ctrl+C Ctrl+V count the periods and return on the 3rd one...
III: You lazy son of a.. I know, it'll have very little change since the 1 lot of photos, maybe less wires for external control?
Quattro: I can see these be a nice replacement for them N-RM! or even 2 of 'em to replace the Avalon Modual3 I have cooking out 270GH/s, oh yeah!

anyway, I'll keep my eye on Bitfury for any info on when they sell them chips, and continue to hound them..

400MHz overnight was a bit of a letdown. 11 hour average 161GH (0.1% errors), slightly worse than I'd expect to see at 375MHz. But 350MHz performance is still good.
I think some of it's probably heat-related. The bottomside heat sink (which the CPU cooler is screwed into) gets pretty toasty. More effective cooling might get things running more smoothly?

That was a paragraph. Or you want me to break everything into single lines like Phil does?

I thought about posting a picture. But then I decided not to because my camera was in one room, the pod was in another, I was in a third and I kinda wanted to go home instead. Maybe I'll do it tomorrow.

Pod's running pretty good now. I have it at the house. The buck chip is staying cool, I'm seeing 149GH (of 154 expected) and 0.04% errors after 4 hours. I'll crank it up to 400MHz here in a bit and see what it does. 400MHz is just a hair shy of an S1 worth of hash, off about one fourth the power of an S1 and in a lot less space.

you see I, I .. I got this problem, you see, all I see is words on words, but no pictures. how does one tell a story without Pictures?!

also, not to be a nazi about it, but can I has paragraphs? its my dyslexia that makes me read about 3 lines then starts following "rivers" along the text.. then I'm like all "Shit, what was I reading?"
