A PSA for everyone with S2's Please check to make sure the PCIe power cables are connected to the PSU nice and tight. I had 2 that weren't tight and it's caused some headaches.
anyone successfully using a subnet other than 192.168.1.x? how about DHCP?
i'd rather not have to hack the files in the firmware to change subnet. Would like to rely on DHCP in the 192.168.2.x subnet.
Anyone doing so successfully?

Well, I finally got mine running. I had to reimage the SD card, and replace the BBB. Good thing I had a couple spares laying around. Not the greatest start, but I can live with the single day delay.
Got the S2 today, 5 boards were out of place, I fixed that, setup the network & it was not hashing. The status page showed x.x.x.x for hardware version and nothing for the cgminer. I just checked the firmware and there is a new version out there 4/4/2014. Upgraded and now it's hashing with no issues.

Does the top S2 in the stack have a dead display?

Not dead, just dim.
Kinda bummed about my dead displays
Obviously check the ribbon cable, but you can also try the contrast dial on the back of the LCD, use a small screwdriver to adjust it, might just wake up your display. Let us know if that works?
Well if you underclock the left too you can get your density as the right for NO additional cost ..... just saying.
I would rather have numbers work because convenience aint going to pay you back in the end. To each his own.....but I like your style if you can afford it
No he wouldn't. He might get the same W/GH but that would make the already worse GH/U even worse.I would rather have numbers work because convenience aint going to pay you back in the end. To each his own.....but I like your style if you can afford it
Footprint is irrelevant, only power usage. I pay $50/mo per rack + Power. So if I underclock the S1's and managed to get the same W/GH then they'd only cost me < $100/mo more than the S2's
... really?! $50? I need me one of those.
+1,
Where can I get $50/mo per rack?

I have some glue on mine too, but it didn't interfere, and there appears to be something under the glue as well. By the edge of the tab, it looks like its been partially cracked or added after the fact or something. The pictures didn't turn out great but you can at least see the glue on both sides. I'll take it out and snap another later tonight, but it works solidly so I'm going to ignore it for now.

Dude, you've been doing this photos with witch's orb or something?

Okay after someone pointed out my algebra mistakes....the Pools are reading the correct hash as I forgot about a missing miner I have.
So perhaps the API is not reporting correctly.....my understanding is the only thing that matters is hashing as seen by the pool and if you have it there you have all you need regardless of other stats.
So on this one I can officially call this one a PEBKAC and its me =)

Edit: though doing the actual accepted hash rate calculation:
35m 51s = 2151s
524000 * 2^32 / 2151 = 1.046TH/s - which is of course OK
So yeah it's most likely the driver doing something wrong with it's work difficulty calculation.

Discard rate?!?
Post the numbers.
Discarded in cgminer is pretty much a meaningless number.
The 2 numbers that matter are the hash rate, and the pool reject rate.

Hashrate is decent, though it sometimes spends a lot more time around 950s than it should.
DiffA: 524000
DiffR: 196882
So basically, 27.3% of your submitted shares are rejected by the pool.
OUCH!
Me thinks the driver needs some skilled work ...

Before I head to the gym, here's the quick video of the initial boot with sound so you can hear the fans. http://youtu.be/sQYtbtsyKdU
I hope you dont sleep with that thing on
well...I'll give it a night and see how it goes...
My discards are also crazy high, haven't updated yet though. Slush hashrate is showing about 700GH/s
http://i.imgur.com/9eQIZmU.png?1
DiffR: 2048684
Yep crazy high again.
39.9% reject rate.
However, the DiffA tells a different story:
Elapsed is 3hr 44min 38s = 13478 seconds
So hash rate for that time is:
3089511 * 2^32 / 13478 = 984.5 GH/s
So it looks like the driver is throwing shares at the pool that are below diff.
Still needs some skilled work on it though

Great news! Got all 3 S2's today. First one's setup and running, after reseating the main board and reconnecting the ribbon cable to the display. One board was crooked but not too bad.
Others have reported major grief after changing to a subnet other than 192.168.1.x, so before turning it on, i connected a 2nd router to the primary router just to create a 192.168.1.x subnet.
So all i've done is configure my pool, and it's working....
two questions:
-what's the best way to shut it down? there is no "shut down" option in the web gui. there's a reboot, but no shutdown. just pull the plug? was it just exceptionally bad luck for the other guy who shut down and couldn't boot again?
-is DHCP to a subnet other than 192.168.1.x working? i'd hate to loose contact with it over something so trivial as a changed IP.

For me I dont have your constraints so I would rather have 40% more hashing power for the same dollar and deal with the power under clock later

OKay I update the firmware.
Given it more time here with Slush the rej rate is dropping as the numbers are not increasing as fast as the start up.
Not sure why its so much better at Slush .....will try Eligius and report back...... still 15% but its declining as the accepts go up.
