Have any S7s made it to the used market yet? Are they holding their resale value? I would like to pick one up to have it hosted, but I don't like paying new full price.

They are still selling more than the price of a new one. Several sellers on eBay refused my $1000 best offer.

At this rate I am certainly going to underclock my S7 whenever it gets here which will be when UPS gets there shit together...

I received 2 replacements for dead boards that I sent to Bitmain. Within a couple hours one of the boards is dead again... What a waste of $ and time. I know their response is going to be for me to ship it to them again for repair, because they did so well at gaining my confidence the first time...

IMO If you're sure it's the same board you sent to them. They should pay for shipping and labor.

Oh man, that sucks Sad

Are you using their power supply?

No. I use EVGA PSUs. I've got several S7s running and the others have had no issues over a several month period.

My friend ordered 1 unit 19.1. and shipped 21.1. (DHL)
My order 7x S7+PSUs was also 19.1. but unshipped yet (UPS)

So for my order from 19.1. still no shipping info.
I really do not understand, why Bitmain some orders (which were placed at the same time) shipped almost immediatelly and some not (and all batch 9, paid via BTC)

I pre-ordered batch 1 at the end of august, I received them 20 october, about at the same time as the batch 2 orders.
My mistake was paying with USD, had I paid with bitcoin, I would have gotten them almost a month earlier. <- Lost about 7 BTC on this.

Did you pay with $ or BTC? Cheesy

And btw, I never received any shipping info or any emails at all, after I've sent them my money.
The only communication I ever had with Bitmain, was getting the order details email.
So don't expect any communication! ^^

That is correct. I just change the OEM FAN speed on 2 of My S7 to give you an idea. The Stock OEM fans moves more CFM then those Noctua so 3000RPM for the OEM is more than 3000 RPM for the Noctua. My garage is currently 73 degrees right now. You can see a 12 degree C Temp swing from going from 4K RPM down to 3K RPM. This is at the lower 675M freq. At the 700M Freq it will be in the low 70C. When the temperature swings in the 80s, you will have issues. So I don't recommend changing to weaker fans for the S7, maybe for the S5 but definitely only for controlled AC environments. The small batch I'm showing are all Batch 9s.

P.S I've tested them via OEM FANs into the 90 degrees. They did well as long as you don't overclock them further than 700M.

I'm in the US, where would be the best place to buy an S7 with a credit card?

Amazon.

In other news, got my batch 9 S7s in today. Three of them have issues with board 2. Sometimes it shows up, sometimes it doesn't. Sigh.

Anyways, I was playing with one of them and installed some of these fans http://amzn.to/1OTMULB and surprisingly it stays around 60 degrees. This is a pretty substantial noise difference. I guess you could just change the stock fan setting to 30-50% and make it quieter. But honestly Noctua makes a damn good fan.

I wanted to keep this S7 at my house instead of the data center. I have it outside in a small shed with an ambient temp of around 70 degrees. I'm impressed. I did under clock to 675 just to give me some buffer. The hottest it got today was 63, and has since dropped back into the 50s now that it is 5pm.

Baazju,

If you keep it in the shed, it's best to keep the OEM FANs as the temperature spike will be high in the Spring / Summer months. Noise can be insulated for the shed and it won't be too noisy. The 2000RPM Noctua won't be sufficient to cool the S7 in the summer months. The 3000RPM Noctua is not as quiet. I've done heat stress test for my S7 and you can replicate this by dropping the RPM on the OEM fans via manual speed settings. The temperature will spike greatly. If you can maintain your ambient temperature in the 70s year round, then no issues. If not it will be a problem, unless you vent out all the heat with something similar to this.

I'm planning to host many S7 in my shed and garage so I'm doing a lot of different configuration testing. I will be testing that 3D printed custom ducts by the end of this week when they arrive. I know the guy who makes them. He's also making me a custom Bitcoin custom FAN grill for not just the WOW factor but also to see if it will fix the FAN speed imbalance issue that causes this S7 to make a very loud annoying screetching sound. I will be covering both in my thread below this weekend.

Thanks for the heads up. I won't be running any miners at my home over the spring/summer. Once ambient temps reach the 80s I'll bring it in to the data center. I'm just keeping it at home for now so I have something to mess around with at night.

EDIT: Just realized I posted the wrong link, I am using the 3000rpm ones. They are quiet relative to the stock ones, but honestly it is better to just lower the fan speed on the stock ones than buy $40+ worth of fans.

I assume you powered boards 1&2 first than board three and the controller?

It might sound stupid but I believe with tougher warranty nowday's if you unscrew and change fan's it voids warranty. - https://bitmaintech.com/productDetail.htm?pid=000201511170341298180m44675v0613

3. In some cases, the warranty will be void, but Bitmain can still do repairs at your own expense if requested. The following events will void the warranty:
a. Customer removes/replaces any components by himself without receiving permission from Bitmain first;

I know it sounds crazy but even a fan mod without permission is now something that can void warranty.

Oh I definitely know. I resell on Amazon and various other avenues and have had my fair share of warranty and returns. I kept one of these batch 9 for myself to play around with at home and do some mods. This one will definitely have the warranty void. Although I doubt they would be able to tell for something as simple as a fan swap. The plans I have later will definitely void things though, but oh well.

Yea I'm not sure if they can tell or not. After shipment i took off one fan once to check if all heatsinks were in place, I'm not sure how you can tell without doing it but I know that is against warranty.

I did see some small sticker edge inside so I'm not sure what they can tell. I have always been honest with them but have been my last rma with bitmain was a S3 board.... so been a while.

Per Bitmain's recommendations I always do the hash boards first, then the control board.

On Amazon you can find them but they're still cheaper to get through Bitmain directly. Update on my whole issue with UPS... Finally got a call and I'll be able to pick up my S7 tomorrow afternoon. To anyone that has a B8/B9 already what settings would you recommend for downclocking the miner?
