rigth you told me. sorry I forgot. I'll let you know as soon as I'm able to apply the new firmware 

I do not have my miner
I wait it back from knc

hi jelin

I won't be able to test it this morning (maybe tomorrow) but it seem that if you have a lot of diabled core 0.96  http://www.kncminer.com/userfiles/file/enablecores.bin (see support page for instaructions) should help.

it seems so but I didn't try myself since I've my machine hosted in a colo distant from my home and I prefer to do this kind of thing "face to face"

Any news about core off
Can make it core on???

sickpig, once I install the enablecores bin file, do I need to restart the machine??

hi trepex thanks for sharing
don't be to harsh your own set up is not that ugly

anyhow I don't rember where but it seems that improving the airflow in such a wa to have a better cooling of the BB helps the overall perf. somone use a magazine to force the air from the intake to "stay down"... as soon as I get more info I'll let you know. it's a real pity that I have my machine in a colo distant from my home :/

i know that all. one die has 40% disbaled cores. have tried 4 pools and at  pools is mining at 220-230 Gh/s. 250 gh/s avg are in cgminer

KnC Cooling & Bertmod temperatures (Saturn miner, 0.95/0.96)

Hi,

with a closed case my temperatures had been like 48/44C.
The die with the hotter temperature often had disabled cores.
Opening the case did help a little bit, the perfect setup for me ended to be like this:



Note the additional airflow by the two external fans (ugly setup, I know!).

Temperatures down to 41/42C and normally no disabled cores (at 0.96). Room temp. about 20-21C.

Even for a Saturn you need additional cooling.

I've applied paper clip at the end of the cable. u can use also a more secure way: http://www.dimastech.it/EN/c/atx-bridge-24-pin-for-power-supply/

you're welcome and let us know your results/imporvements

sickpig, I am somewhat happy, unit was late in my eyes, and was hoping more for like 275GH/s at the server...i think phoenix1969 has 3 saturns running like that....mine seems to top out at 235/240GH/s on the server side...although less than 1% error rate on the server side...so thanks for the input and will check it out...i did post a bertmod result too. thanks again.

I'd give 0.96 or at least EnableCores a try

here is what bertmod is showing...should i run the enable bin file or update to .96??? it's not bad but 100% for both would be nice but not sure if asking too much....

shit ? what's the problem you are minting 251.7 GHs   Is not the best I've seen but not the worst either.

have u use bertmod aisc_status.pl to get the number of cores enabled on  yours asics?

if you have a lot of diabled core give 0.96 a try or use http://www.kncminer.com/userfiles/file/enablecores.bin (see support page for instaructions)

did you check this if this apply to you http://forum.kncminer.com/filedata/fetch?photoid=8379?



 

i'm getting the same shit at my saturn. disappointing. Both boards are marked with an "1"

here are my saturn stats, on .95 firmware, any input would be greatly appreciated...especially my error rate which I am not sure how to figure out.

Anyone got a refund?
I asked for one, cause I was the last to pay for 1st batch and it was approved 2 days ago but they didn't refund yet. I have opened a paypal dispute, so I hope I'll get my money soon, so I don't have to pay more interest at credit card company. I'm dissapointed about KNC, I wanted to mine but the ROI will be negative for 3 months after I get the box.

Seriously don't touch any of that if you don't understand it. You'll likely break your miner.

And thats the source code which is not compiled anyway.

then you could put the psu in there for sure with all that space
