Flattery will get you nowhere sweetheart. You're going to feel even worse when all the loyal KNC customers are mining away on their 3th Neptunes in June and on 6TH in August.

Cheap self serving fear mongering, nothing more, nothing less.
KNC said in their recent announcement that they will stand by and support their loyal customers, and I believe them.

*** Latest news from KNC ***

All,

So last week we really messed up. We sent out products to our customers which arrived broken, damaged and quite frankly unusable.

So in order to fix this the best way we can. We are not asking for these products back from anyone who has received them already. We will simply assume that every card was damaged in shipment even if it arrived undamaged. We will send out to every customer who had a 3TH Jupiter or several already arrive, enough cards to replace their entire collection,

There is no way our customers should have to suffer because of our mistake in not properly securing the components during shipment.
Any effected box in transit is being cancelled by UPS and returned to us to be fixed by our teams,

The factory that produces the cards has been running over the weekend and we hope to have all the replacement cards sent out this week.

Rather than spending more time than is absolutely necessary on this we are going to take the approach of the famous Swedish Furniture maker and ship the box with minimal self-assembly. An instruction video is being made today and will be available later for all to see.
Again we are sorry for not delivering up to our own accepted standard,

Thanks

KnCMiner Team

if i reboot from command line sometimes it goes back to stock settings... weird...

i'm running at 200 and 20 now. no better hashrate. i'll let it run for night.

after the above edits to the file, how do i implement it? Do i have to restart cgminer, use the reboot command, or actually switch off the PSU and switch back on (after a few second delay)?

Bitmain - we have had a great relationship for the past few months.  Sadly, it looks like it's ending.
You are no longer competitive given the S2's fragility and high price.  There are better options that are built more solidly and don't cost as much.
But I'll keep watching.  Hopefully you come to market with a product as great as the S1's were for their time.

There is not enough words to describe how i feel with this news toys.

an average of 1.35 in quiet, 1.45 in normal, 1.55 in turbo. Th/s of course !

The 3 miner are working perfectly. The bottom become very hot, very fast, so to put down the temp i space them.
In air temp : 23°C
Out air temp : 45°C (46°C if I don't space them a little).
The noise of the PSU is the main root of noise in quiet/normal.

Very very nice work Spondoolies-Tech !

It wouldn't be too much if I highly recommend those guyz. Respect the shipping delay, respect the customer with true specs, listening if you have any problem.

On this good words, i'm gonna finish my miniDC so I can post pics soon

Thanks again SP-T

Yep at 225M

for 200 you use '0781' value and '40' timeout?

How many HW errors do you get?

I think you have 4%+ ain't you?

I always get 4%+.... I've tried a lot of settings.

could you please post a code for overclocking? I havent seen the method laid out clearly and simply yet.


I think the voltage of the regulators is the issue, rather than power or temperature.  I have a pencil and a 2000W PSU ready, and am hoping to spend some time with my device tomorrow to see how easily the regulators can all be pencil-modded. 40 resistors total that will need to be modified if you want to get the frequency any better than 225

ssh root@(your miner) - pass = admin
vi /config/asic-freq.config

#option 'freq_value'    '0881'  #225M
#option 'chip_freq'     '225'
#option 'timeout'       '45'  <--- I have changed this from 50 - 40 

option 'freq_value'    '0781'  #200M
option 'chip_freq'     '200'
option 'timeout'       '40'

Has there been any discussion on overclocking the S2?  Potentially adding additional power and increasing frequency?  If there is a different discussion board please point me in the right direction!

IMO, Neptunes will be all shipped by end of June. My guess would be 1st batch starts shipping mid May, 2nd batch mid June

Hi,

Is anyone having issues accessing S2 units through a VPN?

I have two installations behind two different VPNs and cannot access any S2. Other machines behind the VPN are accessible and the machines are accessible when I am directly connected to the network. These are batch 1 and batch 2 machines.

Cheers

What kind of SD card should I buy?  Regular SD or micro SD?  

more importantly, what's it hashing at the Pool??
