Just curious, is anyone biting on batch 6 or are you waiting to see if batch 7 is any improvement. I would hate to submit and buy a batch 6 and then see batch 7 with 4.86TH again...

Would buy a batch 6 if I had any funds left.
It's just a bit slower and probably pretty stable.
You would have no problem selling a batch 6.

Yea, you're probably right, as soon as I get my 4 btc mined back up I'll probably blow it and replace my older miners with it.

Older miners going for a fortune on eBay.
Wanted to get a pair of s3's to warm my garage this winter but too expensive, can't justify price.
Have a pair in my basement.
They are my museum miners.
Have a 7970 graphics card, gridseed orb, gridseed blade, s3,s3+,dead s5 in the museum.
Figured I would keep one of each.
Never did s1,s2,s4. Went straight from gridseed blade to s3.

Holy crap, you're running that pretty hot. My temps never get over 60C.

I only hit 60c when one of my fans punted.
It's like the fan voltage is stuck low.
Fans are probably fine since they are both low.
Everything else looks good.
Maybe a new controller board would fix it.

I have some batch 3, none have 24hr average over 4.86, most are in the 4.7 range and a couple are 4.60 24 hr average.

Troubleshooting I was thinking about starting to check input power level.

Anything else?

Is there any way (in the software) to determine the voltage being supplied to the hashing boards?

good question don't know. I use a dmm and test all 9 pcie jacks.

I would think if it was in software you would get 1 reading for each blade.

that is okay if your hash rate is good and all 9 jacks are giving 11.9 or more volts.

I have found that testing each pci jack while every jack is under load is the only way to be sure you don't have a psu issue.

Really test every PCIE Jack? On a single-rail PSU I would think as long as all the connections are solid you should see the same voltage on all.

Now if you are using a multi-rail PSU, then yeah you have to test every lead. But then again if it were me I'd toss a multi-rail PSU anyway as I played that game back in the GPU days and load-balancing was no fun when you are mixing/matching rails. Manufacturers often hide the rail configurations so you are left guessing, and normally dedicate one rail to the mobo connector so that becomes worthless!

Long story short: I love my 1300W 108A@12V PSUs. Worth every penny!

It's a nice idea but unfortunately not. It would need some additional hardware and then software support for that.

Anyone experience a issue where changing the pool information is not saving?

Have you logged into that device with SSH at any point? IIRC making changes to the config manually (via the shell) could make the web interface not save changes. Let us know if that's something you've done.

Also, I've found with previous units that simply pressing "return" (enter) on your keyboard does not "save" the pool settings. With previous units, I actually had to click "save & apply" in the bottom right hand corner of the miner configuration. This may have changed with the S7. I'm not certain of that.

Didn't SSH in, and definitely hit the save and apply (in an increasingly frustrating fashion) - it refreshes, but defaults right back the original antpool setting.

Thanks for the tips though (usually is something simple that I forget).

Sent an email to Bitmain, will see if they have any insight.

Are you using the October 23 firmware?
Acting like the conf file is read only .

Downloaded an upgraded (600.tar) - same results.

Several reboots.

Use 50% or 40% 3,240 rpm

Everyone's RPMs seem to vary quite a bit. My 40% is significantly slower than that.

Hi, can be normal the S7's fans are running at 2.400 rpm and the internal temperature is at 70ºC? I don't know why they are not running faster. I tryed to put them in auto, 80%, 90% and 100%, but no changes... Someone have same issue?

Can you post a screenshot of the status page and configuration page please?

Re second batch 2 (575 miner): definitely best at 575.

A little Mac related quirk:

if you use default Safari to download the 575.tar.gz, it automatically ungzips it and you have a 575.tar in downloads and 575.tar.gz in trash.
If you try to ugrade with just .tar file, upgrade fails (it says that you got a short file).
If you download with Chrome, everything is fine (you get 575.tar.gz file in downloads) and upgrade proceeds uneventfully.

As a result of upgrade I got much less errors, lower fan speed and slightly lower to same temp of the boards at 575.
