Bitmain problems

[swilla]

I had issues with the two S3s that I ordered. Got in touch with Bitmain and received the go ahead to return them for RMA. That was 1/3/15. I just got them back about a half hour ago, and they are the same exact miners with the exact same problem. NEITHER of them work. They had good reviews, but my experience has been horrible. AGAIN,I feel they are nothing but CROOKS! And if they aren't crooks, then their management is sub par to say the least.

Good luck and welcome to the pain train...

Their customer service is radically useless, all they do is tell you shit and don't come through.

Unreal incompetence, worst than even eBay/PayPal.

You could spit on a wall and get better results than getting anything done with Bitmain customer service.

One big run around meant to get you to give up on their crap and buy more.

Go read the forums of their hardware, the proof is there, I used to have 10TH/s of their crap.

Now down to about 4TH/s and going Spondoolies in the new year.

Many long term buyers of Bitmain are fed up of their junk service and switching providers; just like I am.

I paid more for my last few orders just to get better service; just got fed up of arguing with their non-sense.

Been a buyer since 2013 and still get the "go fuck yourself treatment"; which is just a run around of incompetence.

Again, good luck to ya, seems like don't matter if you bought 1PH/s or 100GH/s you get the same junk, Fischer-Price service.

In your case, I should thank you for helping me make my decision a whole lot easier.

Where did you buy from? 

If you want a warranty you need to buy from bitmain or their official resellers.

I got them through cryptocrane, but they are just the middle man. They are warranted for 90 days. Neither of them lasted more than 10 minutes.

Are you able to describe the problem?  Someone might be able to help if you tell us some more info.

same exact miners with the exact same problem

I can try. Okay here goes, like I said I purchased 2 S3s from cryptocrane. The shipping was fast and the packaging was great. I was sent the wrong PSU, so I couldn't hook both of them up. I had an old PSU from a scrap computer. Hooked one of the miners up to it. After a couple of minutes the PSU was smoking. Okay, must've been a bad PSU. A few days later my other one arrived. So I hook same miner up to it. BOOM! That one blew.(which was a 750 watter) Well, hell I bought 2 1000 watters. They got here and I opened them up, hooked the same miner that blew the last two up, and within minutes that PSU was shot. What the hell? Bad miner, gonna have to return it and run the other one. Hooked the other miner up to the other 1000 watter and wouldn't you know BOOM again. What the hell are the chances of that? So, I figured maybe I was using shitty PSUs, so I broke down and got a EVGA 1000 Supernova G1, got to hook the miners (yes, wishful thinking, I know.) up and nothing. The one that fried the 3 PSUs is completely dead. No fan no red or green LEDs nothing. The second miner's fans work but nothing else. Again no LEDs. Using their guide I tried troubleshooting them and determined that was a lost cause. Got in touch with Bitmain and was told to send them to Colorado. I did. I get them back tonight and like I said they are the exact same miners I sent them. Melted plastic in the connector and everything. Figured maybe the fixed whatever was wrong. Hooked them up and same thing. The one that blew 1 PSU the fan comes on but nothing else. Other one is dead. Now, my question is what the hell was the point of sending them to them if they weren't gonna fix them. Just wasted money on shipping. So, that's about it. Any suggestions?

I feel sorry for what happen sir.

But this is all your fault. You should not use shitty psu. Miner is power hungry monster. Give them scrap old psu, that what you get back.
The miner make psu explode because shitty psu had no overload protection. Then the psu get angry and make miner dead.

I hope you learn something from this boom.

[goxed]

Always go with 80Plus Gold / Platinum PSUs. 1000W or higher is highly recommended initially, until you get the hang of it.

Yes, I've learned my lesson about this. That still doesn't negate the fact that I paid to ship 2 dead miners back, just to have them returned dead. I mean come on, they didn't even try to test them, or they would've known neither of them worked. And then they have the audacity to try and say what they sent me were new miners from a different batch, which is a blatant lie. That's not how a company is supposed to run, I don't give a damn what anyone says.

I can sympathize with you. Bitmaintech shipped them to you.  To say a third party seller is an issue when they came factory direct is a bit cheesy.

Now you used a psu and instant death

 https://bitcointalk.org/index.php?topic=671189.msg10016458#msg10016458

at this point in time  you should have joined and posted here.

I can also say posting a thread with a curse in the title is not the best way to get some help. It puts the company on the defensive.
Bitmaintech is pretty good but not perfect. I don't think they can send you a new s-3 due to the change over to s-5's.

Maybe they could have sent 1 s-5 to replace the 2 s-3's.  Keep trying to get a replacement.  I would think that the first s-3 you deserve a replacement no questions asked.

A 600 watt psu should run a s-3.

[aclass]

One S3 should run just fine even on the most weak shitty PSU. even if the PSU burns, the miner should be just fine, if the connectors are not melted. If there are melted connectors, then it's a bit different. It might be that your connectors were not good enough and could not bear the current going through them. It also might be the miner's fault, if the connectors are not well soldered. It might be even loose connection between the two connectors.

What model shitty PSU did you use? How is it rated on the rails? What are the other ones?

If BITMAIN claimed they sent you different miners, this is not very nice of them to lie.

Did you send them pics of the miners or did you just mail them to them? I'm asking because many vendors will blame the user if there is something melted.

Going with Gold/Plat PSU is not a must. Yes, it is nice on the power bill but nothing else. On the other hand going with good PSU is a must. One has to read before buying.

This is an interesting case so keep us posted.

The first one was one that I acquired a while ago out of an old tower. Unknown specs, but it was running 3 Rockminer new R-box 100's for my buddy. And I'm pretty sure the S3 doesn't run much more than that.
The second one was a Chiefmax (or Cheapmax) 750-watts total ATX form factor 140mm cooling fan with intelligent fan speed control Over-current protection Over-temperature protection 20/24 pin ATX power connector 8 pin EPS+12V connector with detachable 4 pin P4 +12V Six (6) Serial ATA Connector Six (6) Molex power connectors Two (2) floppy drive connection Two (2) 6+2 pin PCI Express video connector Retail Package Includes: 750-watt power supply Power cord Specifications DC Output +3.3v +5V +12V -12V +5VSB Max 36A 38A 40A 1 A 2.0A Min 0.5 0.5A 0.4A 0A 0A
The third and fourth ones were Kentek 1000 (ordered the 950) 140mm large fan Quiet Performance and High energy efficiency ATX 12V version 2.3 and EPS12V version 2.92 Spec Intel AMD Spec Matte black color coating and Ball bearing fan and matel gurad grill Mash cable sleeve for easy cable management SLI ready SATA 20/ 24 Pin ATX 4+4 Pin Short circuit and over voltage protection
No, I didn't take pics before I sent them. (lesson learned) I was just happy to be getting 2 new miners. Yes, I was told completely new (different) miners. Alas, now I've got a 80 gold PSU with nothing for it to run. And those aren't cheap. I'm telling you, ALL I WANT TO DO IS MINE SOME COIN. Why is that so much to ask? I have kept every correspondence I've had with bitmain. I don't appreciate being shat on. Especially since I had every intention of purchasing more products from them.

That's not true. On the way out a PSU won't necessarily stick to 12V as various internal things start turning to goop.

you are correct but  the op said he could run 3 100gh

 r boxes  that is   about 375 watts.  so  I am thinking the first s-3 was a bad unit.

remember he got the end of life s-3's .---------------------I base this on the assumption the op is telling the truth.

 the last set was  a little less quality then the previous 3 or 4 months based on various complaints.

Of course I can see the viewpoint of bitmain and without photos the entire complaint is a bit suspect.

At least the op removed the curse word in the thread title.

[sbogovac]

[...]Bitmaintech shipped them to you.  To say a third party seller is an issue when they came factory direct is a bit cheesy.[...]

I understood the OP that indeed a reseller sold them and shipped them initially... And Bitmaintech only returned the RMA...

Don't know, but in the Netherlands consumer law would also insist you first take it up with the reseller... Not the manufacturer.

On the other hand - although I believe it was the PSU - I, myself have had to do with Bitmaintech's CS and am NOT happy with them. They push back as hard as possible to make you do the work and do not RMA that easily (hell, even BFL RMA'd easier!). And I gave up (because although several S3's weren't running up to specs [>5% less], but at least they worked...). So for me, also: no more Bitmaintech and hellohoo Spondooliestech for a next purchase... Pay a bit more, but get premium service in return (as far as discussed in these here fora).

The biggest problems I have with the SPTech products is they are so freaking loud At least with the S5's, you have options to make them run more quietly, but the SPTech stuff is too loud for "home mining" even at their quietest settings

Don't get me wrong, Bitmain is nowhere near close to walking on water, and I agree with you that SPTech offers some killer products. Both companies are the only two I would deal with at this point in time, but both also have their pro's and con's.

Very frustrating.

At the risk of sounding like I'm making excuses, I'd like to think Bitmain is just "that busy", but I can verify your sentiment with the S3's. The S3 launch ruined the "honeymoon" period I was having with Bitmain. Thankfully, my two direct-purchased S5's have been performing very well (if not louder than I would like), so I can't anecdotally say anything bad about the S5's despite the unfortunate reports I've been reading.

Could be worse. You could be running Butterfly Labs gear ! Oh wait...

[philipma1957]

To me s-5's and  sp20's   are both good and both have pros and cons.

I got my one s-5 to run dead quiet .  I run it at freq 300 with 2 delta fans at 5.5 volts from an external psu total gh is 1000.

I had 1 bad s-1 in feb.  bitmaintech offered  an RMA  but no cross shipping and replacement would take about 10 days. At the time coins were 700 usd and 10 days down time was unacceptable.

Minersource bailed me out they shipped an s-1 upfront on trust.  My delay was 3 days not 10. I send the dead s-1 to minersource.

I did get more then 30 good products from bitmaintech.  1 dead.  If I count u1's I got 250 good ones 3 dead.  the reseller sent me new u1's

I rate bitmaintech as secondplace and spondoolies as first place.  with asic miner a distant third.

If he honestly thought that an S3 had blown up his perfectly good / adequate PSU, why would he put a further THREE PSUs on that unit as each subsequently fails? I don't think we're getting the full story.
