I am a PSU short and don't get paid until Thursday so can't go with the Coolmaster.

That is a great PSU. I have 2 of them.

I've renamed the experimental one. Here is an updated one with more tweaks to the tuning (does not delay before disabling):
http://ck.kolivas.org/apps/cgminer/kncminer/cgminer-tune
(Be patient before deciding what its performance is like since it takes many minutes to stabilise)
Updated that binary again. It delays re-enabling them progressively more every time they're disabled. The delay between disables is back and there is now a message saying that the cores are being enabled and have finished enabling at startup. It takes ~20 seconds on my saturn!

That's what i got too!

KNC was on Swedish TV per hno :

http://www.svt.se/nyheter/sverige/svenskt-bolag-i-centrum-for-bitcoin-utvecklingen

4th picture has their video.

Haha they were wondering if someone would see the news report and mention it here. That was Andreas speaking, no idea what was being said, or the relevance with setting a young lad's trousers on fire at the end of it was. He's since quit the random acts of arson...

'Orama i want Sam's t-shirt. How do i get one? Please please pretty please!

I agree. Anotherhost has been hosting my 3 Jupiters with no problems.

So if someone says "I'd never use anotherhost" is that a compliment or a criticism?

It looks like Phenix 1969 is right about cleaning up the power.

My old UPS was stressed out and would not support the Saturn upgrade to a Jupiter. So, I had it plugged into the wall for a couple of days.

I got an APC BR1500G -- with AVR and AC line filtering. The unit bumped up from 561GHash to about 568Ghash (up to 569). The error rate dropped from 2.5% HW errors to about 1.2% to 1.6% Will know better in a day or so.

The unit now draws about 708 watts -- the UPS can handle 865 Watts -- that gives me five minutes -- which is fine -- I just want the dropouts taken care of so the unit won't reboot on a very short outage.


I also got a better power Supply Seasonic X Series 1050W (80 Plus Gold). That did not work out so well -- it just shuts off after about 30 seconds to a minute. I guess the 12V line cannot take the stress. I will see if the store will swap it for a different unit.

The Corsair GS800 power supply is back in use. I suspect it's noisy and that a better unit would give a slight improvement in the error rate.

Cheers.

Give me this day my daily Bitcoin...

except short term mine says anything up to 680+++

eventually it simmers down to 529 regardless. Right now its at 509 ffs!

perhaps we all need to rewire our houses for optimal performance of a 600w rig or 2 ( i can see this being a good idea for cats with half a dozen rigs for sure) but will it bring dead dies back to life???

will the 'tuning suite'?

Dave, you might also try connecting the 6-pin PCI-E cables directly to the modules themselves, instead of using the blue extension cords provided by Knc. I don't know if this has any effect because I never used the blue cords to begin with, but I'm thinking it can only serve to provide more stable power to the asic boards.

@BitcoinOrama:

Can you help me buy a Hosting service at KnC now for my Nov. Jupiter (#8743)?

I am afraid of Vietnam Customs for this special device.

Thanks!



You PM'd, but it's the weekend and no Cust serv are in until tomo, so I'll mention it then mate. Haven't heard of any issues with Vietnam, pretty sure we have sent there before...

Make my day! Say thanks if you found me helpful Smiley BTC Address --->

I noticed the BFGminer poll on the main page... anyone using it?...results?

it's there since forever Tongue

Anyway I've try to use it 2 days ago. I've compiled it from source using this instructions http://codepad.org/QKSeO5zh from an ssh session. I've let it run for 10mins but there were many cores enabled/disabled and it didn't seem to settle so I've turn it off and switched back to cgminer.

I've used the first version of cgminer-tune on my lower perf jup for almost 20 hs and that's what I found:

- extremly more narrow min-max performance interval. It used to hash  @610-15GH/s as max (only for a few secs) and after that it went down to 450. Now it's hasghing around avg +/- 10.

- slightly higher WU (20-50)

- almost the same cgminer hashrate as before (maybe a little bit better) (I don't have data for @pool hashrate for this machine alone)

- a lot less cores disabled at the end of the road. 10 instead of 20.

ok, on the pool side is no difference to notice, however it's a minor improvement on the road to max performance  Smiley

do you happen to have the link for 0.98.1 beta at hand ?

It looks like Phenix 1969 is right about cleaning up the power.

My old UPS was stressed out and would not support the Saturn upgrade to a Jupiter. So, I had it plugged into the wall for a couple of days.


Cheers.
Dave, you might also try connecting the 6-pin PCI-E cables directly to the modules themselves, instead of using the blue extension cords provided by Knc. I don't know if this has any effect because I never used the blue cords to begin with, but I'm thinking it can only serve to provide more stable power to the asic boards.

Once I get a power supply that seems to give less noise and is behaving properly I will give it a try. Thanks for reminding me.

It does not make sense to me that the jumper cables could be an issue -- the wiring is adequate - there are no "loose pins" -- but then I did not expect anything significant in the way of performance improvement by installing a UPS. Other than preventing shutdowns due to power dropouts that is... In retrospect it does do AVR and it has a better AC line filters -- so sure it can make sense.

Sometimes things don't makes sense till you discover the cause of a problem (sometimes unrecognized even) and analyse backwards from a solution.

Ok so added the modules, started and all the normal lights came on. The only prob is its either not hashing or not connecting to internet.....i cant find it in the net work...

By the way i have a saturn and just made it to a Jupiter.

I am about to reset it any other suggestions ?

Reset it -- do the easy things first.

My Router/Modem shows me a list of all IP addresses -- it did indeed change IP addresses even though off for only a short while.
