It all looks new. No dust ore so. Don't know about the sound. I fixed it right away. At 63 db now.

Interesting.
Just one point.
During the operation miner sometimes accumulates static electricity (maybe because of all that blowing).
For example, when you have a sweater on and touch it with one hand, sometimes it gives you a bit of a jolt.
The point is, I wonder if it could spark with the metallic outer tube, causing electrostatic discharge (ESD).
ESD is known not to be good for electronics.
maybe grounding the tube would not be a bad idea.


Good point. I will do that. But in the tube the S7 is sitting on some rubbers. So i think it's oke. But grounding it will be beter.

'The right to privacy matters'
Phil, the included data cables are long enough to stick 2 or 3 of these to 1 controller? Can we get a picture of how the 2 of them look together?

I ordered custom cables

 I have a photo wait a minute


here is a shot of my controller loaded for 6 boards.  so:

 1)full
2) full
 3) full
4)full
5) blank
6)full
7) blank
8 )full
9) blank

2 custom long with 4 stock short  this allows for 1 cat 5 not 2 and 1 unused controller




this shows the long and the short cables.

'The right to privacy matters'
Yeah try 50 % and 593

What you running yours at Phil?

556 and 55%  but I have 2 in a small room  which is too hot due to warm weather in NJ.   79f yesterday 60f overnight.

once temp drops  to 50 f outside  I can go to 593 and 45-50%

Sound is fully managed.
The rooms temp is 89f  and will drift to 93 or 95f during the day
The gear is running at 57f to 59f
Setup is temporary until I finish cleaning my garage.

@beffje: lucky you! you did not get a used dusty unit! looks nice, nice pics!

Does it have the slightly whinny noise, because of the original 25mm fan in 38mm case? only at high rpm should be noticeable

i think that it takes some time to stabilize, even more than 2 hr.
what exactly is fan % changes? i changed to 90% and it is the same fan speed as before-4200/4200 (it did not become 3800).

65% = 4200

40% = 3600

35% = 3200
30% = 2800
25% = 2500
20% = 2000


fantastic, thanks

my s7 seems to have low % of error so far.
0.0062% error at 600 hashing 6hr at 4830-4850, temp 52-53C, fans at 4200/4200
0.0068% at 606 hashing 2hr at 4870-4890 temp 52-53C fans at 4320/4200
0.0087% at 612 hashing 2hr at 4950 (shweeeet!) temp 52-53C fans at 4320/4200, wattage went up ~25W between 600 and 612, gh increased as expected ~100gh

tomorrow I will try reducing fan to see where the similar hash would be with higher temp.
I am pretty sure that it can go to 59C, maybe at 600 or 606 and lower fan

WoW,

So I tough my nightmare was done when I lost 1 day for the custom in China ... Guess What ... Took 1 day in the US and it's taking 1 more day in the Canada.

Did they send me drugs instead of miners ?

I never see that before... either it's bad luck, DHL sucks or i'm been flag by my government ...

DHL "Express" yeah right ...

I'm Cdn too. I've had decent luck with UPS when ordering from Bitmain. Maybe, try them next time.

Got one up and running for two hours. It has EVGA Gold 1000 on two boards and EVGA Gold 650 on one board and controller.

Getting 4,845 on default 600
Temperatures are 50,50,51 
Fans are 4,080 and 3,960
HW is .0065%
Drawing 1,271 watts from wall
I am mining on Eligius.

I have it in the same room with several S5's and I don't think its really any louder. It just has a lower pitch noise then the S5.

I know this seems strange but freq 612 has a lower error rate 0.023%; I highly recommend trying it.  

I tested 6 different freq.

givens:
time:  15 + minutes
PSU:  silverstone 1200 on 2 blades, SS750 on 1 blade and bone
pool:  antpool
HW:  taken from the Diff1#  column

Code:

freq GH/S(avg) HW watts w/gh amb temp temps fans
587.5 4,534.00 0.04% 1159 0.2556 25.2 (49,46,46) (4200,3960)
593.75 4,583.53 0.04% 1172 0.2557 25.2 (49,46,47) (4200,3960)
600 4,600.97 0.06% 1185 0.2576 25 (49,46,47) (4200,3960)
606.25 4,426.16 0.14% 1188 0.2684 25 (49,46,46) (4200,3960)
612.5 4,505.14 0.14% 1206 0.2677 25 (50,47,47) (4200,3960)
618.75 4,411.42 0.18% 1215 0.2754 25 (51,48,48) (4300,4080)



this is a second s7 runtime 18hrs
Code:
600 4,629.18 0.07% 28-32 (55,53,54) (4440,4200)


my take:


stable basic btc miner.. thank you bitmain... HOWEVER, it should have been sold as a 4.6th miner, not a 4.8  imo

I will be running mine at 593 freq.  


update:  so here is a twist.. moved it into the DC room and after 20 minutes at 593
temps are 55 with a 4500 fan
Code:
22m44s 4,698.61 4,693.60

WU is almost at 68K, speed is still climbing (currently ~4840GH average) at 600 while temp stays in at around 53 even with my current 81F ambient (it is still freakishly hot for the end of September-90F or slightly above outside).
HW error 0.0067%. it might be able to overclock, I think, or 600 (default) is optimal for this machine
Remember last summer S2 with WU at 14-15K using 1.1kw.
Gosh, i like scientific progress.

yeah it seems like higher freq net like 50-100GH at most.. but vs higher power draw it might not be worth it for such a small bump.

my troubled s7 running stock settings is slowly climbing after 1.5hrs its at 4725gh and 0.04% HW
