Topic: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH - page 373. (Read 527816 times)

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
 
45% of the revenue generated in the first month goes toward paying electricity.

That's a lot!

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 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.  

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.

 

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.

Will I get S7 coupons for buying the S7?

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

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. 

Oh man!

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

damns, yo!
