Thanks for chiming in David.
I would love to be PRO Bitmain, and have been in the past given my past experiences.
I bought around 30 s5's early last year and had one fail - controller and boards. I sent them in and had replacements 2 weeks later.
I did send an inquiry email after they had it for a week, and they responded and asked for patience but that it would be soon.
Too me that was acceptable. These past 3 weeks however have been discouraging. Without any feedback at all - not so good.

I did finally get through to one of the Mobile phone numbers for support and spoke to a pleasant sounding lady.
I was disconnected 3 times, and kept calling back and getting her again. I'm not sure if it was bad connections or what. In the few minutes we were connected it was hard to make out everything she was saying.
Her English was quite broken and connection wasn't the best. I think I'll have my fiance call in as she speaks fluent Mandarin, but don't really want to bother her as she's busy teaching at Penn State.
I did kind of make out that they could not access the bitmaintech support tickets online, so that might be part of the problem. I told her I also emailed direct to [email protected] too.
She told me to email again and they'd respond by tomorrow. I hope so.

Thanks for the update.

I'm about to spend a lot of money on power upgrades. I'm not following through with it if I can't trust my supplier. I just sent another email to [email protected]. I've always been kind and respectful in my emails and taking up for them in the forums. I cannot continue to do so if this continues.

Maybe someone will send the replacement blades I'm suppose to receive soon. I say this because I'm beginning to have second thoughts about upgrading my power now. If they were in my situation, they would feel the same way. Wouldn't you?

I posted info about how many purchased and how many had issues a couple posts down.

As for Underclocking the batch 3 - I'd rather have some boards functioning than leaving them at 700 and having them fail - especially if support is not going to live up to warranty replacement.
I don't see how underclocking would do any thing to void warranty - if anything it should rather extend it.

I have sent 4 emails via support page and a couple to [email protected] directly. No response for 4+ weeks.
I've tried calling the Denver support line today, got voice mail. Been trying to call the 3-phone numbers in the AUTO Response email that emails result in.
All say - Sorry, the mobile phone you are trying to reach is currently turned off. Should be about 2pm in Shenzhen right now.

BITMAIN,

WHAT IS UP WITH THE LACK OF PROPER SERVICE OF LEGITIMATE CLAIMS?

WILL YOU PLEASE RESPOND TO ALL LEGITIMATE CLAIMS IN AN EFFICIENT AND TIMELY MANNER. IT WOULD BE APPRECIATED GREATLY!

KIND REGARDS,

DAVID

With an s7, rule of thumb is : overclock if you want, underclock if you want, find a good setting with sub 0.01% error, and then - DONT TOUCH IT EVER AGAIN.

Also check out the luck we had at Kano.is pool

Only thing is if bitmain catches you doing overclock it will void warranty. Current batch 8 I have not seen a overclock to make it worth losing warranty for.

Chances are they will not catch you. But it is possible they might depending on problem you have. (Which hopefully there will be no problems and not need warranty)

It seems they won't warranty the product anyway.

I lost another b8 hashboard today. It was underclocked at 675.
Guess I shouldn't have moved it above 650. Still no word on the 2 batch 5 boards I sent to Bitmain.
Will be 4 weeks on Monday. This batch 8 board had been running 3 weeks. Lost another batch 8 board running stock 700 about 10 days into mining.
Emailed Bitmain about it and again - no response.

It should be good for 3 month's. I have luckily not dealt with RMA since S3 day's. Honestly on batch 8 you should leave it at 700. If you mention over/underclock that ruins warranty. You have to get permission to do pretty much anything now.

I would email/send ticket/possibly contact US support if you are getting no where. But they should respond to email. How many units did you buy and how many had issues?

Already ordered some batch9 can I still change it?

I would think you can if it's not marked "shipped" yet.

However, I'm not sure if you can make a special note now. You may have to go to the order and click it to see if you can. If you cannot, I would at least make the addition to your address with that HST CODE included next to your street address and in place of your EIN/SSN number.

EDIT: Probably not a bad idea to go ahead and call UPS and tell them you need to add an HST CODE to a shipment coming in from China and they will transfer you to the proper department to take care of it. I'm telling you this because of this episode I went through: https://bitcointalksearch.org/topic/m.13432585 I have to wait 6 to 8 months before I find out if I have to fork out almost $900 because of a mistake an agent for UPS made by applying the wrong HST CODE to my shipment that resulted in charging me a 2.6% tariff.

Now there is always someone who opposes you, you will never do this,
I'm fighting just to eliminate these mistakes, and I also opened a poll, but here people are afraid that bitmain not send more miners to end users,.
these people are the classic form of chickens, but by man have nothing, and the world goes to pieces for these people.
cmq you did a great job to specify these things, let's see if people wake up and pull out the balls.

After you have chosen a carrier [I chose UPS as an example] here is where I was talking about adding a note for delivery with the same HST CODE I mentioned above "HST CODE: 8471.41.0150": You can even go as far as to be more detailed in that NOTE to the carrier for delivery by stating the following:

8471.41.0150

Which is:

8471
Automatic data processing machines and units thereof; magnetic or optical readers, machines for transcribing data onto data media in coded form and machines for processing such data, not elsewhere specified or included.

41
Comprising in the same housing at least a central processing unit and an input and output unit, whether or not combined.

What exactly do I put in there?

When I look at my old shipping labels on recent packages I received, I do not see my company's EIN number on them. I would still put "HST CODE: 8471.41.0150" next to your SSN or EIN number. However, It is more important to put "HST CODE: 8471.41.0150" next to your street address. I believe you also are allowed to give a special note to the carrier when you place your order with bitmaintech.com. I recommend also putting "HST CODE: 8471.41.0150" in the special note to the carrier when you place your order with bitmaintech.com.

EDIT: You see my address covered up in purple. I put "HST CODE: 8471.41.0150" out to the right of my street address and out to the right of my EIN/SSN number as well.

EDIT #2: When looking at the address label on each package sent to me from bitmain; it does not have my EIN (Employer Identification Number) or SSN (Social Security Number). Which means by putting the HST CODE out to the right of the EIN/SSN number will not be on the address label. However, there may be some other piece of paper accompanying the shipment with that info.

I recommend everyone in the US make the following changes to your ADDRESS in your BITMAIN account to include the proper HST CODE for rigs shipped into the U.S. That's if you want to avoid a potential tariff charge like myself and some others received for improper classification of shipment under proper HST CODE. I put the HST CODE in two (2) different places on my address. Which can be seen below.

IF someone makes this ADDITION to their account address "[HST CODE: 8471.41.0150]" and receives a shipment soon, please let us know if your carrier assigned [HST CODE: 8471.41.0150] to your shipment.

I see many are using the EVGA 1600w power supplies with the S7, but I don't see anyone mention the Corsair AX1500i (Titanium) that comes with 10 PCI-e power connectors. Is anyone using this power supply or have tried it? Not interested in how expensive it is, it's not very far from the price of the EVGA 1600w T2 (Titanium) where I'm at. It's $392 on Amazon, vs. $430 for the EVGA on Newegg.com, so it's actually 10% cheaper in the U.S. Plus with the Corsair connected to a nearby computer through the USB port, you could monitor the power usage I believe.

ax series corsair has 7 year warranty.
I use three rm1000 corsairs per two s7's, 28 s7's total.
Have been running 2 months with no issues.
rm series has 5 year warranty.

I'm waiting on 2 dead hashboards to be RMA'd as well. They probably won't receive my boards until next week though. Hopefully I won't have to wait a month after that to get working boards.

When they replaced my controller it took over a month. However, I sent them 3 dead hashboards on Dec 23rd. I had the replacements in my hands on Jan 6th. Problem is that one of the replacement cards died after 10 minutes. I can't see any reason for it to die -ie: heat sinks still in place and no burnt smell. So back to working on another RMA for the same batch 1 S7. My Batch 8s are 1 month old and seem fine so far..."knock on wood".

That's Interesting! Wonder why they haven't replaced mine or even bothered to respond to email inquiries. They've had mine in hand since 12/14.

Hmmm- maybe they took pity on me because my rig hadn't been working for 5 weeks due to the first problem- ie: controller issue.

I did use the evga 1600 t2 and last year the corsair was priced close to 499

Wonder why we can't use Denver location for shipping back fail part and getting new replacement for faster speed and same time zone support. Sounds like they're not leveraging the full use out of the Denver location yet. Would love to see that as a future option.

So I have to re-try getting a board RMA'd to bitmain. I bought a brand new PSU to try to power that board up hoping I was using a bad psu and there was still no go. For those of you who have fully opened their S7, what is the easiest method to getting the top off so I can remove the problematic board? I assume the top comes off because you can't simply slide the board out of the casing.

Remove the rectangular plate behind the fan, boards will slide out. But I would contact Bitmain before opening the miner.

Just remove the plate behind the fan and they do slide out? What about the piece sticking above the top of the miner where the pci-e cables are connected? That's not part of the hash board?

Yup, just removing the plate behind the fan will do. That plate is holding the boards in place.

Cool, I'll try removing it tonight. Bitmain already agreed to 'test' the board at their facility in china. Sucks I have to send it there, but the 3 TH hash I get from a $1600 miner really blows.

Good luck with your RMA.
I had bitmain OK sending back 2 dead hashboards, and they have had them for nearly 4 freeking weeks!
I've sent several emails and they have not responded, both via Ticket system and direct email. Not only am I out the dead hashboards, but also out the $100 shipping fee back to them. I also openned another ticket as I had a brand new batch 8 hashboard fail after about 10 days of hashing. No response on that either. Still waiting for the 5 day late payment on batch 1 too. I'd have to say, I'm sorely dissapointed with the service received from bitmain - especially given the amount of money I've sent their way in 2015.

I'm waiting on 2 dead hashboards to be RMA'd as well. They probably won't receive my boards until next week though. Hopefully I won't have to wait a month after that to get working boards.

When they replaced my controller it took over a month. However, I sent them 3 dead hashboards on Dec 23rd. I had the replacements in my hands on Jan 6th. Problem is that one of the replacement cards died after 10 minutes. I can't see any reason for it to die -ie: heat sinks still in place and no burnt smell. So back to working on another RMA for the same batch 1 S7. My Batch 8s are 1 month old and seem fine so far..."knock on wood".
