Can somebody tell me what the effect is of a high HW? If you have two different miners at the same speed, they hash about the same but one has a much higher HW. And on the pool there is also not much effect.

so the 1 unit I have thats been a pain in the ass so far has dropped to 3.9TH over the weekend (with no dead asic chips) and stock 600 settings.. going to try a hard reboot via PSU and see what happens
still tons of HW errors, im going to drop freq to 593 and see what happens. BITMAIN replied to me via email and asked what PSU im using, asked to try different pool (im using antpool, go figure) , and asked me to plug in each hash board individually and take screenshots of their hash rates..
only problem with that is it seems to take a couple days for the hashrate to crash on this unit, and I don't really want to waste a week of mining testing on each hash board individually.
hopefully the 593 freq will work out, i could live with 100GH loss instead of 900GH
That is exactly what they told me! One of mine is running at 4300th/s. Now I have to troubleshoot and see which board is causing the problem, then probably send it back to bitmain and after 3-4 weeks they will send me another board. Let me know your findings.
593 freq is running great so far! 4730GH/s avg at almost 7hrs with 0.026% HW ...ill take this all day long over the high HW and lower speed at stock settings, not sure how ours passed QC checks
try the lower freq and see what you get

Mine looks like dogie's with the pci-e outlet on the side of the controller.
It's been running for 4 days now and consistently between 4.810 - 4.830 at 600.

Your picture is from the older version of S7, manufactured from S5+ leftover components. Controller and housing. Now we have a new and "better" S7.
Except this housing is difference to that of the S5+? The ones I saw certainly weren't extruded aluminium.
New S5+ housing is from aluminium. Exactly the same shape as your old S7 miner.

damn it looks like mine are the same as Dogie's review unit (the older style I guess?)
thats kind of a rip, I ordered day 1/2 .. do we know what "better" means on the newer S7?
the main tell is the controllers power connector on the older S7 is pointing out the side just like the S5+.. the newer S7 looks like its pointing up
I see the difference on controller on PCI-e going up.
Is there more details as far as the housing? I guess I would love to see side by sides if anyone happens to have both.
Looks pretty similar, just larger bulges and slots to link them together? I'm not sure we should really care, although my S7 seems to be clocking higher (675) than others are reporting?

I see the difference on controller on PCI-e going up. Does the "new" one have 9 slots for blades still I could not tell from picture looks like still nine i'm estimating after looking at it again..
Is there more details as far as the housing? I guess I would love to see side by sides if anyone happens to have both.
Yeah I think its 9 slots also on the new one.. but if you look close the little notches in the ribbon cables all go the same way, the older S7 and also the S5+ have the notches going different ways on each side of the controller

hmm interesting.. im running both of them on a 2880w psu with the jabberwock breakout board
after 4 hours at 593freq im at 4720GH and 0.026% HW
after 4 hours at 593freq im at 4720GH and 0.026% HW
Could well be PSU variant, on a DPS-2000 I managed 650 perfectly stable with 2 PCI-Es and appeared to be the same on 675. 700 gave a low hash rate.

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.
Grounded, thanks for the tip Biodom
do you have a link to the 40 euro sound killer, or where can I buy them what is it called?
really like this idea.
I bought this from a growshop around the corner. But don't think you guys have that.
I found one that does europe. http://www.eugrowshop.eu/uk/fans-odor-control/sound-insulating-exhaust-hose/exhaust-hose-sonoconnect-315mm-10-metre/ I have the 315mm.

It really depends on the power supply. I use 6 board with one controller.
My first choice was APW3-12-1600-B2 with 4 boards and EVGA G2 1300 for 2 boards and controller.
Lower speed and over 57000 HV with 4 hours.
I left APW3-12-1600-B2 for only 3 boards and for the other three boards + controller 1x DPS-2000 BB with 10x PCI-E.
Speed is now over 9500 GH/s and HV ten times lower with 4 hours.

Site Maintenance, should be up online as of now!
"Order list" still seems bugged. Pay: shows as 0, and clicking on the order doesn't show all the information anymore.
Edit:
And its back!

Unable to buy anything on the site right now.

Internal test for R1. When does the R1 would be available?
somebody posted R1 internal sales by mistake. No way it would cost $5, LOL.
yeah, $5 and $25 shipping.

It is and the AntRouter is listed. It says 10 units limit and the price is very low, i would of liked to get one unit and test it but i'm guessing they instantly sold out.
I noticed after one minute so they must of gone fast.

Went to check on my order status and Bitmain website is down. Most likely crashed from everyone checking
