I just received an S7 earlier today for reviewing for a computer hardware site, AMA!

Here are some quick things I've found during a couple hours of testing:
-The miner is VERY loud. Compared to a ZeusMiner Thunder X6/GAWMiner Falcon, this miner is definitely louder. However, one thing to mention is that although the unit has two fans, I suspect one of the fans is dead (swapped plugins, fan shows an RPM on the Miner Status page but isn't spinning up at all). So if both fans were working, the unit would probably be a little quieter. But it's the miner is very audible through a door, about 30 feet away, even when listening to music slightly louder than a normal conversation through speakers. However, this single fan blows a ton of air, similar to other miners. It blows enough air to be an effective hand dryer. The noise really reminds me of a vacuum cleaner on full speed.

-My review unit is hashing away at about 4.60TH/s. A little lower than what BITMAIN claims, but still a very good rate.

-Import fees were fairly high for me, BITMAIN claimed the package as the full value when shipping it out, and I was charged a total of $131.48 CAD from UPS for delivery ($121.48 for customs fees, and $10 for brokerage fees)

-The unit uses DHCP - no more plugging it directly into a PC and modifying settings if you aren't using the default 192.168.x.x domain hardcoded into older Antminer miners, very nice for those not using the 192.168 subdomain.

Those were a few things I noticed during the first couple hours of testing, but yeah, be sure to let me know if you have any more questions. I don't think I'll overclock it for awhile, so don't expect to get answers on that.  Tongue

While I thinks it's valuable and important to get the 2nd fan operating correctly, I'd be stunned if it actually made it quieter. It might make it more tolerable, but I've yet to see a situation where a 2nd fan ever made anything quieter. The hot air and noise are to be expected when you have 1200W being generated inside an envelope that's roughly S5 in size. Bitmain can't alter the laws of thermodynamics it would appear.

Will I get S7 coupons for buying the S7?

I actually didn't know about the coupon thing..  Tongue




Oh man!

You could've used (or sold!) those 15 x $400 = $6,000 in S4 coupon discounts!

damns, yo!

Hi..i am Paul from malaysia. nice too meet you guys.
i am planning buy S7 antminer and i have two S5 miner in mining.
because the S7 is quite expensive.. So i try to come here looking S7 coupon.

I'm not sure on those.  There was a point they  made coupons very easy to get.  If you emailed them they gave the to you.  And they gave a lot to people who got them.

So they might not have been worth much at all.

No only certain coupons are able to be used.  This is what has made them valuable this time.   Also not a ton got the coupons so it made it limited amount.

We really need a coupon thread though so it does not keep taking away from this thread.

Using mining calculator at https://tradeblock.com/bitcoin/mining , I am shocked of how much the monthly electricity cost will be for running this full time in California 24/7: $167
 Huh Shocked
45% of the revenue generated in the first month goes toward paying electricity.

That's a lot!

thats because its california. A lot of places pay <50% of that

24" PCI-E cables with 16AWG wires and stripped ends - great for server PSU mods, best prices https://bitcointalk.org/index.php?topic=563461

Turns out the second fan was working the whole time, it was just the fan grill that made it look like it wasn't working (derp). So my previous noise level estimates were taken from the unit with both fans working.

Also, I just took a power reading and it looks like this miner takes 1200W exactly for me, using a LEPA 1600W PSU.

Can you do s video of the miner to get an idea of sound and some pictures in detail?

Anything would do Smiley.  Finally not speculation if these are hitting doors now. 

And the shipped ahead of start like normal. Seems they keep a habit of it.

Sure, I can try and take a short video of it hashing away a little later today. I've taken a few pictures already of the unboxing, but I'll take more of it all hooked up and hashing as well. Should have the video of the miner up in about 10 hours or so at the latest.

how are you using the lepa? do u have some converter from 8pin cpu to 6pin?

does it have frequency and voltage control?

temps? is the case warm at the back?

thx!

I'm using the GPU/CPU/RAM rails on the LEPA to power the unit. I have four PCI-e connections on rail 12V5 (three connectors powering hashing boards and one powering the controller) and two connections on each of 12V3,12V4 and 12V6. So in total there are 10 PCI-e connectors on the miner and that's how I split them up.

Haven't looked into frequency or voltage control on the miner yet. I mentioned before that I  don't plan on overclocking this unit for awhile, so I don't have any numbers on that yet. However I suspect it has at minimum frequency controls.

After mining for a few hours the outside case is as cool as when the unit is unplugged. Obviously quite a bit of warm air is blown out by the fans during operation, but case is nice and cool and hashing board temps are from 44C-49C for me with an ambient temperature of ~ 20C.

Careful with only running 1 fan.  I had an AM Prisma that only had 1 fan.  The miner was using ~1100 watts and the single fan failed.  In a short order, the miner caught fire and was destroyed in a nice flaming bunch of expensive electronics.

Watch air closly as you dont want to get to hot.  Warranty has changed a lot on what you can do at this point.

Open up a RMA with a ticket and hopefully they send you one for free.  If nothing else it documents you had permission to mess with fan.
