I guess with the extra wattage the PSUs will run with slightly less heat.
What do you mean by "and don't care if 7.7TH are down".. Do you mean down (failure) due to not following the warranty instructions?
@cniht & @sloopy,
I appreciate your responses.
Yes, that is what I meant, and do not take my posts or replies as harsh in any way, but I do hope to present things as they were presented to me by BITMAIN representatives via e-mails.
The phone support people I have dealt with have all been over the phone. Those guys answer the phone from the main number and transfer to customer service. I do not know if they are all living in Colorado, but all spoke english very well, and were straight up with me about the way things are. - Unfortunately they do not make final decisions. At least decisions like should we swap this unit for another, but they can certainly help you out, and have me. I went through batches 1 and 2 of the S4 power supplies before I gave up, but it wasn't from those particular support guys lack of trying. Through many discussions with several of them I learned what happened, what was going down, what they could do about it, and what they couldn't. I have mixed emotions about them offering to send me a server PSU (DSP2000) with a break out board, but today I look back and think at least they offered when they knew they couldn't fix theirs.
Email is where you talk to people who have the authority to make decisions. I spent days reading existing threads for the products I was interested in either before or after I purchased them. I wish I'd read every page before, but some of the units were used deals I grabbed quickly from e-bay. My worst experience was a new purchase through Amazon. Avoid those in my opinion although you can find a deal on ebay sometimes but you have to watch and be patient. The prices are generally much higher than they are here in the marketplace.
I also avoid resellers for new equipment because they simply have to mark it up. I will again throw an exception out there. Lee from Lees group seems solid, but Phil and others can give you the best information on his setup. He is more local to the factory, gets great deals, and I have seen him meet and beat BITMAINS store price, but he requires you host with him for X amount of time which I cannot do. When it comes to the point I cannot afford to mine I will have to pickup another addiction of putting my hands on something. I have no doubt others can vouch for other resellers who they have seen with great deals, but the only ones who matter are the ones you can get that deal from today, and (repeating myself again) who BITMAIN will put in an e-mail they will warranty for that person / company.
If you are asking everything specifically looking at the S5+ I have to say, my expectations of the S4 were too high relative to what I received. The product, was not what I expected for the money I spent, so the S5+ I am keeping my expectations in check. Even though it was 9+
BTC / 2,500.00 USD I know it very well could arrive DOA, maybe one or more boards do not function, maybe I have to fight it a bit to get it on the net, maybe the CGminer is old, maybe the corner of the shipping box is ripped off, maybe there are fork truck holes through the box, bent heat sinks, loose cables, dirt and rust, and on, and on. I am not saying these things would all be the fault of BITMAIN, I am saying these are more realistic expectations from what I have seen reported and through my own experiences. I do expect it to be packed well, even though there is a thread right now for one of the used S5 batch 7 units where the guy said his wasn't. It has been rare I hear of them using poor materials or methods in packaging. All of my S4s were packed perfectly in anti-static and a great soft foam cage to handle bounces. I expect good fans. They will be loud as hell and rock the house, but again the S4 had some issues with fans and needed to have the stickers pulled back and grease added. BITMAIN took care of people on the fans. I think most of us who lost a fan under warranty bought our own replacements and sent the originals back, but I know of cases where BITMAIN did send a fan out without having the original back as well.
Other than political stuff with warranty and the time it takes to ship things they have improved, and there are always opposing views to anything you say here, but consider this. I was one of the biggest opponents to BITMAIN gear when the S5 was released and you couldn't have melted one and poured it in my house without getting shot, but a few months ago I picked up a couple of used ones, and after getting over the high temps they report I have been happy. The S3+ is the best built BITMAIN miner I have owned. (I didn't get in on the S1) If the S5+ stays on pace with the S5 with the exception of the obvious things which will need attention right away - cooling! Then I know what I bought, and I bought Batch 1. Buying BATCH 1 of anything from BITMAIN is a huge risk but also can be a big advantage depending on many variables - the early adopter ideal -
Keep to the warranty statements to the letter.
IF you aren't sure, ask BITMAIN and get in writing from them. I do not say this to say people are dishonest, I say this because misunderstandings happen, and they happen even more when the boss is in china, or the questions and answers are being translated from english to chinese, just get it in writing and e-mails are fine.
Keep your documentation from your order being placed and confirmed like you keep your bitcoins. Backed up, printed copies stored in several locations haha. Seriously though, that is your only warranty ticket and what you will be asked to send them for any warranty claim. Keep a digitized / scanned / emailed copy handy,and a printed copy somewhere else.
Just because a guy here on the forum pulls his apart on day one and re-pastes the heat sinks doesn't mean you need to do so. They are dead serious about not doing anything without their permission and people can tell many things. They put marks, stickers, etc all over the place sometimes. I do check the cable connections. I'm not dismantling the thing to do so without their permission which I will ask and I expect them to say yes. It is not unheard of at all for things to work loose between here and there, and I haven't been told no but CYA - cover yo ass -
Again, I am not saying all of this and repeating certain things to say BITMAIN is a bad company. If I thought that I wouldn't have ordered one. I am saying these things either because they are first-hand experiences, or there are clearly defined, informative posts from reputable forum members reporting the issue more than once. By reputable I don't mean they have HERO or LEGENDARY by their name those accounts are bought and sold daily. I mean people I have read things from which proved to be true time after time and as much as any online persona can have trust, I trust what they say. Some of those people only have 100 posts, and most have much more, but it isn't the quantity in my opinion. Some of them are huge assholes at times as well heh.
I will have my own pictures up when possible. Maybe customs decides they want to mine for a few weeks, not much I can do if that happens, but I know how to ship products to many countries and so does BITMAIN. My information will be facts. When I give an opinion I will state such. I tip my hat to BITMAIN on the S5+ not because it is a piece of breakthrough technology and something which will give me some huge advantage, but simply because they are the only company putting something out which we have a chance to ROI with. This whole game is a gamble and I have no doubts I am rolling the dice by having placed the order, but at least it was under 2,500 and they do have a good record for shipping on time. For the rest I cross my fingers and stay positive and relaxed until there is a
real reason not to be.
As far as the S5+ making more sense than buying 6.7 or however many S5s dude was asking about.
There are several reasons for my use but I have to run and I am sure people are sick of my longass posts but a couple are the efficiency and the ability to control the heat because of the density. I didn't use a heater in my house after Christmas last year and I do not plan on doing so at all this year. I will be able to run ductwork to route the heat the way I want. Pushing or stacking the S5s doesn't work out the same for the way I have in mind without much more work. I have a bunch of S3s I will be selling soon and this seems to perfectly fit the bill. I do not like the central point of failure, and if this first unit comes in the way I hope (not expect) then I plan to order at least two more right away again, because it is a gamble. I don't go to casinos, I play with bitcoin and support the economy by buying, mining, and spending coin.
We shall see how the unit does, but I will keep a positive attitude and hope for the best. If the S7 drops in two weeks great, we have more offerings, but I am again gambling a bit because I do not think it will.
For everyone, please post up your experiences, n00bs or not, put up pictures and what you think about things. Document the good and bad. That is the only way we can help each other. I don't want 15 legendary reviews which basically say the same thing. I want to hear from Jane and Tommy how they made out with their new gear on top of the Legendary guys who have been around since CPU days. Keep it all coming!
