There's a very valid reason why you don't just turn off your computer by yanking the plug out of the wall socket - and flipping the PSU switch is the equivalent of doing that. Do that to your desktop computer a few times and see how well it runs as a result...

Yeah I have turned PC off GPU rigs at the switch a couple thousand times. It is a non-issue. There is a reason open frame GPU miners used power supplies with a physical power switch on back.

you missed the whole point, the motherboard being hooked up properly with those pins tells give the PSU a reference as to what to do and that its ready to shut things down instead of POP powers gone.

And here is a tip for everyone. You know those two pins you jump to make the PSU work? Do you know what those are used for?

When you press the OFF switch your motherboard opens those two pins, telling the PSU to power everything down safely. That is the only correct way to shut a system down - pull the jumper, then power off the PSU.

If you just flip the PSU switch off, you leave a "whole lot of amerage" suddenly looking for the quickest way to get home. And electrons aren't fussy, if they can find a shorter path across a component instead of thru it, they'll use that. If there are unseen micro droplets of solder on the solder mask that present a shorter path, they'll use that path, carbonizing the solder mask and making it an even BETTER shortcut - resulting in nasty smelling smoke and burned solder mask...

Just flipping the PSU switch to off might not break anything the first time or even 100th time you do it, but eventually you'll pay the price, and the magic smoke gets out. There's a very valid reason why you don't just turn off your computer by yanking the plug out of the wall socket - and flipping the PSU switch is the equivalent of doing that. Do that to your desktop computer a few times and see how well it runs as a result...

Yeah I have turned PC off GPU rigs at the switch a couple thousand times. It is a non-issue. There is a reason open frame GPU miners used power supplies with a physical power switch on back. The theory that it powering off highly regulated UL listed ATX power supply destroyed connected equipment doesn't hold water.

There are ~300 million PC in the US. If yanking the power would blow up a motherboard 1% of the time and the average PC experiences 3 blackouts a year then you would be talking something on the order of 9 million destroyed PC every single year. Say average PC is $500. We are talking about a half a billion dollars. If it genuinely was a problem then PC mother boards (and GPU and other hardware) would come with circuit breakers or at least a $0.20 quick burn fuse. Of course they don't ... because it isn't a problem.

I think we all need to step back for a second and chill out on the KNC folks.

We have to remember that this is a collaboration between Orsoc and KNC, and both companies have reputations on the line. If I were to speculate (and that's all we can do without any information coming from KNC) then as soon as units started having problems, the Orsoc guys put the breaks on the project. To be honest, I can't even blame them. You can't be a long term success in this industry if your products burn houses down.

I'm guessing that:
1) KNC and Orsoc are madly working on the issues and will have them fixed as soon as humanly possible.
1) KNC isn't allowed to say anything about the problems due to the agreement between them and Orsoc.

Nobody wants a unit shipped to their home that is going to achieve 1/10 to 1/4th of the expected hash rate. Nor would I imagine they want one that catches on fire. I'm not involved and have not special information, but I know KNC will make this right.

Not sure but FractionalReserve posted this on KNC Forums www.kncminer.com

hopefully this fix is the real deal

Asic Bords with 4 VRMs - bug - cool properly until FW fix arrives!

Today, 04:07 PM

The new asic bords with only 4 VRMs are using to much power.

KNC will release a bug fix for this in next (0.95?) Firmware hopefully arriving in short (Today?)

A Jupiter in this Config will use app. 890W. So it can be difficult to start with a 850W ATX. (You can still run them with only 3 boards conected)

The VRMs are also running over spec with app. 50+ A current each! They probably won't burn, but if you can cool them extra until the new firmware is realeased, do it!!
The Asics are tunning to hot (+70 deg C) as they get app, 0.9V instead of 0.7V as they are supposed to. Cool them as much as you can!!!

The Problem is due to the VRMs not working according to spec but KNC will be able to fix it with new firmware (we did our own patch for our miners yesterday).

Easiest fix to cool properly is to provide cool air, belo 20 deg C is a good idea. Open case + big fan will also work.

PS, this does not apply to 8 VRM asic boards. No worries here.

again found this on knc forums

hope if helps

Searing

I pointed this out yesterday and it kinda got dissed by the KNC collective

you don't fix something that isn't broke unless you know everything that can break it

I, for one, would like to see that shown experimentally. I personally believe there is no fault in pulling the plug.

W. T. F.?

This is running 0.93...umm help!?

thats odd, my exact process:

arrived with .91 only did 190 gh/s on jupiter >> updated to .94 ssh in and do reboot.

waited 15 minutes for it to come back online, major issues >> updated to .92 ssh in and reboot

waited again, miner wont run at all now >> ran reboot patch, rebooted

still wont run >> updated back to 93 rebooted

miner runs and gets near 480 GH/s now

in this case, the jumper is the paperclip?

None of this "its the HX850's fault". That model might just be particularly susceptible to this problem... But I have used over 30 HX850s for mining-related functions without a single issue till KnC.

Well that fucking sucks. Thanks for being cheap knc. I was so happy when I heard people were getting under 600w. I was hopeful that these 1300w PSU's from BFL could power two of them. Looks like not anymore.
