I'm thinking of buying 2x 140mm fans and just put them with cables ties on the outside of the case at the rear (exhaust side), so they can help a little bit with removing the hot air.

Thermalright TY 143 look nice and coupled with a fan controller you can run them quiet and slow or noisy and fast.

L152 mm x H140 mm x W26.5 mm
Fan Weight : 170g
Fan Speed : 600 - 2500 rpm (PWM)
Sound Level : 21 - 45 dB(A)
Airflow : 31.4 - 130.0 CFM

Or one can get a more advanced one with a display and thermal probes = monitor the temps inside the case directly Smiley
Hey Cyper, wouldn't it be better to add the souped-up, more powerful fans as the inlet fans and put the existing f14's at the rear to suck out the air? I think it would be more important for temperatures to improve the inflow than the outflow.

Cypherdoc - FUDcaster General, coming to an unrelated thread near you very soon.

Actually if you look carefully, I never came into this thread to criticize or spread fud prior to now. That really doesn't make sense if I was trying to disrupt their business. In fact I was one of the first to congratulate them a couple of weeks ago after the demo video.

Buy yeah, you know what? I am a big protector of bitcoin in general and when I see any company screw up the economy after having collected so much money and behaved so arrogantly Imo,  I'll let them have it.

Did you let BFL, "have it" then?

Good point. No.

But the KNC warrior bunch was a one of a kind virulent bunch of trolls that tried to destroy Hashfast and my reputation based on nothing except to try and protect their investment.

They also kept this thread pushed up to the top for visibility.

Now things have gone terribly wrong.

Hashfast still does not accept paypal or cc. Easy as that. When they do, you can come back here and troll on. Until then my consumer rights are more protected with KNC. Also - A miner Protection Program for a whooping 5400k premium? Bitch, please....

I don't want to complain too much as I am a DAY1 customer that did receive one Saturn at home and another one
online hashing at the KnC datacenter. I also received my (first ?) bonus/compensation from KnC.
But I also thought I post this comparision (as reported by Bitminter):

and uses 270W (at 230V).

I think the interesting point that hasn't been raised yet (as far as I've seen in this epic thread) is how KNC have binned their chips, if at all. BFL have 2 chips per Jalapeno and each can be (and usually seems to be) of a different quality in terms of hash rate and they must manually balance which chips get put on which board to achieve the advertised hashrate. Bigger boards have way more chips and it then becomes a classic partitioning problem.

Given that a Jupiter has only 4 chips, each of which must be of a different quality (bin) how are they choosing which chips go in which box? Pure lottery or an undisclosed system? I understand that each chip has many cores and the firmware is attempting to disable bad cores in an effort to manage the binning at runtime, but the variance in the aggregate chip hashrates shown by people on this thread show that this strategy isn't yet working as intended.

Simple question: KNC are you speed testing each chip/board before placing it in a box?

Second question: What is the minimum guaranteed hashrate of a Jupiter?

or maybe they should of gave a miner to the designer of bfgminer/cgminer...

screw that ....put them both on a plane....with "agreeable blondes" ....fly them to Sweden work them like slave pay them well....they can keep the blondes


(hey just saying for coders you could run the world on software.....maybe that's how google does it/ ... with this method)

but truthfully a plane ride accomodations and 'good pay' would more then make it self up with the miner software all buffed up and shiny imho

Very good point, AFAIK, the chips are currently not binned at all. Not even tested for functioning (neither wafer probing or final chip testing) before being soldered on the PCB. Thats a huge mistake IMO, one that was pointed out months ago. They could be testing/binning the completed modules, but Ive not heard a word on that.

WELL this is kinda off topic..but in regards to the KNC miner issues...we may be complaining about a brush fire in back and are unaware that over the hill ROME is burning

not good imho

Second question: What is the minimum guaranteed hashrate of a Jupiter?

As advertised:
"550+ Gh/s per device"

(from https://www.kncminer.com/categories/miners)

They could worm out of it by saying that this is projected hashrate for November delivery, but remember the launch video?

http://www.youtube.com/watch?v=JFOcI8nK2xI which is currently linked on the front page of their website. This is what they are claiming they are shipping "The actual hashing performance" to quote Sam. And "It's not 400GH/s". "It's a 500 machine"

Notice the massive X through the 400GH/s.



So forget 400GH/s.

Anything less than the 500GH/s and they are misrepresenting, which I'm fairly sure would be a criminal offence.

yeah they would have probably been "golden" if they simply said we have 'stock units" that will do 400gh ....we have some experimental mods that look promising that have gotten as much as 550gh depending on the quality of your chips" we will make this available to all to play with....but in an effort to get the units out the door at this time we stand by the 400gh or 150gh more then we originally thought in April......we will have a place on the forums for these "experimental upgrades" all are welcome to try asap.


its all on how you "present stuff" imho

bad!

If I were in your shoes I would try bertmod. it' not a real fw upgrade, it doesn't require a reboot, it just replace the status web page with a new
one with a lot of more info. (see: http://forum.kncminer.com/forum/main-category/main-forum/6183-bertmod-0-2-unofficial-firmware-mod-feedback-thread)
if you think it's too risky... the .bin file is just a tar.gz, extract it, copy asic_status.pl on your miner and then run:

Code:
perl ./asic_status.pl > status.html



My Saturn unit at home runs 0.93, case closed (but optimized the flaps/wings inside the case = bent them to not disturb the airflow)
and uses 270W (at 230V).

do you mind to up a pic of your internal airflow optimization?

Sure.
This picture was taken with an iphone through the closed case, sorry for the bad quality.
I don't want to open my case at the moment.

Remember, it makes only sense for Saturns. Those flaps/wings (how would a native speaker call them?)
make much sense for a Jupiter!

Thats a huge mistake IMO, one that was pointed out months ago. They could be testing/binning the completed modules, but Ive not heard a word on that.


I just installed "bertmod 0.2.1 by uski" on my bad performing Jupiter (only 380 gh/s). And shows two Asci-chips (2 and 3) with lots of disabled cores:

ASIC_0
   Die_0: 48 cores on, 0 cores off
   Die_1: 48 cores on, 0 cores off
   Die_2: 46 on, 2 off
   Die_3: 46 on, 2 off   >> 98 %
ASIC_1
   Die_0: 48 on, 0 off
   Die_1: 48 on, 0 off
   Die_2: 48 on, 0 off
   Die_3: 48 on, 0 off  >> 100%
ASIC_2
   Die_0: 47 on, 1 off
   Die_1: 47 on, 1 off
   Die_2: 19 on, 29 off
   Die_3: 47 on, 1 off  >> 83%
ASIC_2
   Die_0: 48 on, 0 off
   Die_1: 48 on, 0 off
   Die_2: 3 on, 45 off
   Die_3: 48 on, 0 off  >> 76%

In total there are 81 cores off. That's about 10.5 % not working.... This while I'm only hashing 412 Ghs at the moment.  As 412 / 550 is about 25% less performance, I guess that there is quite some overhead in the FGPA management and Firmware to "steamline" a stable system (about 15% additional loss)....

Firmware: 0.94
PSU: Cougar S700
Cooling: default + 2x Noctua NF-S12B FLX




Any adivce on PSU?
700 plenty... you might try raise your diff a bit more...  like 250


Ok raised diff to 256, working fine with 260GH/s.

Just asking for PSU advice cause Cougar S700 is silver certified and my  saturn wasn't stable before connecting two Noctua Fans to PSU(sucking air out)
KnCs PSU specs say, PSU must be gold certified, maybe thats why i'm getting so much HW Errors?
I'm also looking foward to buy 2 upgrade modules next year so i need to change PSU anyway.

Silver, Gold, etc. refer to PSU internal efficiency.  Wouldn't have anything to do with H/W errors.

Suppose you have a 500 W power supply, a system that pulls 250 W at full load,  running at full load all the time.

Power drawn from the wall in an 8 hour day:

Basic - 312.5 W
Bronze - 304.9 W
Silver - 294.1 W
Gold - 277.8 W
Platinum - 271.7 W

That means that over basic you save 7.6 W/h with bronze, 18.4 W/h with silver, 34.7 W/h with gold, and 40.8 W/h with platinum. With 8 hours a day at full load that comes out to be 1.82 kWh, 4.42 kWh, 8.33 kWh, and 9.79 kWh saved per month with bronze, silver, gold, and platinum respectively.

At 0.15 per kWh, and a 24 hour day, you'd save $52.86 a year with a platinum supply versus a non-rated supply.
