^^ 50btc was hit by another dos attack today. I was down for about an hour
40deg and 38deg temps on my Saturn (case cover off)
just upgraded to .094 and hash rate is a little slower but HW errors are at 10% . I purposely stayed on 0.91 before this as the results from the other 2 firmware patches didn't look too good. around 5% HW errors on 0.91

Agreed, the Jupiters I have on 0.91 are the fastest without any doubt. I have none on 0.90, most on 0.91, none on 0.92, two on 0.93 and one on 0.94.

So far 0.91 is the real deal IMO.

I wonder what firmware the guy whose boards caught fire was running.

0.92

in fact we had 4 fires/burnt caps so far

2 x 0.92
1 x 0.93
1 x 0.94 (this one today at the datacenter of anotherhosting.se)

Was it always the same or equivalent cap - by my earlier glance it looked to be always at the same end of a series on the board?

There was mention somewhere of 'cricket' noises coming not from the fan but from the ASIC - my suggestion would be that it might have been coming from a capacitor?

A very cautious finger could be used to check cap temps generally - capacitors should generally not run very hot I think ? - and so one that is hotter than the rest might forewarn a problem.  Also, if it's possible that firmware plays a part in this (and firmware was having something to do with noise) then upgrading firmware might only be done after the capacitor is damaged.

obviously they are saving parts, i got only 4 voltage regulators instead of 8 per board
this causes high temperatures and high power consumption...(and lower Hashrate)

That's interesting.  Only 4 of the 8 are actually working anyway (as seen with bertmod).  They probably realised this and decided not to pointlessly install 8.  As such, it shouldn't make any difference.

It's all in the details, literally.
How about a clear answer to my 2 numbered questions above?
Bump.

https://bitcointalk.org/index.php?topic=170332.msg3307588#msg3307588

Surely with your obsession for detail, it must be eating you up not to reply to these?

P.S. KNC still shipping in those unsuitable single walled boxes? Three whole questions for you to answer, in detail.

P.P.S. How come on the controller board there are 6 terminals, but shipped miners are only being shipped with 4 in place? Four questions, awaiting details!

Bump bump.


Questions consolidated for our details man who loves to give people what they want:

How about some answers to these questions:
1. How come the sub-standard cgminer from KNC?
https://bitcointalk.org/index.php?topic=18313.msg3294238#msg3294238
This post suggests the KNC version is not doing a proper work restart. Any reason KNC are spending 9 days releasing firmware updates that doesn't even fix these issues? I'm fairly sure the guys who wrote cgminer could sort this quick fast.

1.5 Update: It seems the binary for knc cgminer has not been updated at all in any of the firmware updates (source: irc). How come? There is plenty to fix.

2. How come boards are bbq'ing?
I know you wrote a post a few days ago trying to blame people for unplugging cables while the miner was still powered up, but that was scapegoating. There is plenty speculation on the hardware issues causing, but a total no-answer on this from you/KNC. Customers are worried about burning to death in their sleep.

3. Are KNC still shipping in those unsuitable single walled boxes?

4. How come on the controller board there are 6 terminals, but shipped miners are only being shipped with 4 in place?

Five questions, awaiting details! thx

Sounds like the Jupiters can possibly be upgraded to 800GH+ with two more cards.  No room in the case though.

in fact we had 4 fires/burnt caps so far

2 x 0.92
1 x 0.93
1 x 0.94 (this one today at the datacenter of anotherhosting.se)

4? Ouch! Out of how many?
Either way, guess we now know why they are only tested for 30 seconds. Probably with a fire extinguisher at hand.

Seriously though, thats not good, at all.

Not any more. They only ship with 4.

It's not a problem making/buying a bigger case.

I would like to know why only 4. KNC not going to support upgrades for their loyal customers?

I think the case is pointless anyway.   They should of flat shipped it and just let us put on the heatsinks.   The way they slap on the fans (and how they fall off) I wonder how great they paste and mounted the heatsinks.   I have very different temps on mine.

That could mean a lot of things of course, but it would be one less thing to wonder about if we assembled most of this ourselves (and would of gotten mine a week earlier no doubt)

I think many of us were relying on it, that's why we are miffed these 2 extra terminals were removed and make the jupiter a fixed 4 board system.

And so "upgrade" now seems to mean "buy a completely new one".

I can confirm is a stale party indeed, flushwork seems not very good. Got a huge rate of stales.

Well, I guess that when they will iron out the firmware we will see some impressive performance on knc gear

They were probably safeguards/margins in case some terminals did not work. In any case, no one promised 6 ports. I expect to be able to upgrade Saturn to Jupiter, but not further.
