You Sir are very insightful!   

a hard reset and power cycle brought it back to high voltage again

it is screaming now holding ~525 at BTCGuild  (just think if I had the other 59 cores)

Observations:

temps are up about 7-10C each board (to be expected)
the one board (KNC 1) that was really low on HW errors when not overclocking, has the highest, while the others are all under 5%  
similar amount of cores as last test (gained that one back to 709)

we'll see how this goes after a few hours...since my temps are still lower than many people's non-overclocked jupiters it looks sustainable. (all 4 VRM boards)   Dropping the fans to the crossbars does help in these situations

I should change the PSU though, it is only an 850watter

900+ pages.

Double? Impossible of course. 

But looking at hashrate versus earnings, double the hashrate and halve your earnings for a given hashrate.  So, if the network hashrate hits 30PH/s in January and it's well over 3PH/s right now, then just to stay even one would need at least 10x the hashrate just to earn the BTC one earned today. 

Get that?  What's impossible even with the 10x scenario is that it will only earn the same BTC/day that one is earning now - and how much would it cost to increase one's hashrate ten times?  And to get delivery in January, when would one need slap down the coin for the equipment purchase?

Can't answer your question but I did test all 0.90-0.95 looking to see where the voltage dropped and saw the last .9v was .094.

My 8 vrm Jupiter never has the output voltage above .7*v

Is this the case with everyone else with 8 voltage regulators per board? I'm on .94 I've never taken a reading on .93 or .91 so I don't know if its better or worse. I don't want to play either as I'm getting 508gh/s showing on eligius 12hr! Now 24+hr with out reboot as well.

Perfect, thank you kindly.

I have not had any issues today at all with my miner on Bitminter.

Can someone tell me the exact type of cable used to connect the controller board to the asic boards? The ones that go into the 4 asic slots. They're grey with light-grey connectors.

Did anyone else's hosted miner go bonkers today? At around 10 UTC there was some downtime, and when I checked the portal, we suddenly had statistics. Ok. But a few hours AFTER that, my miner started to drop its connection to BTCGuild or Bitminter, and never reaching more than 80-90% of the speed it has been running at for days, and then dropping to about 50% speed, fluctuating wildly and also dropping connections the last few hours :-(

Curiously, the hash rate graph on KNCs portal pages say that the miner is running at full speed since around lunchtime, whereas the BTC Guild graph looks like a rollercoaster, with my average hash rate for today less than half what it has been the last week :-((

I guess they have updated the miner firmware, but it was certainly an "upgrade" I wish they hadn't performed in my case. Curious to hear if others have the same symptoms. Hope this change is reversible!

I'm not able to register and post on the KNC forum, hope somebody here - if they have the same problem - can crosspost.

I see, you tried 0.96 and then 0.94 gave you the .7 volt VRM output voltage?

Then I'll stick where I am until after the next diff increase and likely beyond that.

Well, I've had FM 9.6.1 running all day and I think it's slightly less performance than 9.6.0

It could be that it was not about performance, but more safety or less errors.

I was averaging low 250s and about 3700 WU, now the hashrate is 248 and WU is below
3680. It would reach that low of a WU after about one day before, but hashrate would stay
at 250 or higher.

Although another factor could be that the two previous days were quite a bit colder and it's
in my basement.

I believe you have to do the secret handshake to get it to switch back to high volts once you go to .95+  

It might need a hard reset or perhaps going to an earlier firmware first..  i kinda forget myself the surefire way of switching them back

I would think you could statically compile the binary so all the libraries are linked into the final product, then stash that on /config.  Then just copy it over to /home/root or wherever to actually run it.  

Should be able to tar it up. Maybe save the packages you need there too.
hno said /config/network is executed at startup..

yeah i tried that first but no go on /config for compile

but can we compile/create something and then stash it in /config?

I can't support that. /config is vfat.

The /config directory survives reboot. You could build in a subdir below that. 
(type 'mount' and see cryptic details)

I don't understand how you are getting .7 out of the VRMs on firmware 0.94.  I'm running 0.94  and have .9+v and don't see .7 unless I run 0.95.
