at least in Antarctica you would of got free heat!!

they told me they test them up to 105 celsius but I modded my airflow to keep everything between 40-59

try changing the thermal paste on the heatsinks so there is a thin layer instead of it being excessive and squashed out of the heatsink.

how much speed should one expect after connecting the miner to pool? doe s it take 24 hours to reach full speed?

mine seems to be fluctuating between 180 to 260

reported already, this is the reply I get

Dear xxxxxx,

 

We aware about this issue. Please be informed, there should be new modified firmware released later on today. It should help you to make it more stable.

They are not shipping anymore, because they are stuck in their datacenter and HW/FW problems.

think it must be reported to KnC engineers while they fix it

How many RJ45 ports does your wifi router have?  Are you connecting more than one item to a cable modem?  Cable modems (sometimes) come with a USB port and an RJ45 port.  This does not mean you can use both.  It's one or the other.  If your home has a single computer to the cable modem then that's all the cable modem is going to accept.  If one wants more than one computer to the cable modem one plugs the upstream port of a router to the cable modem and then has the multiple downstream port switches (RJ45 ports) and possibly wireless.  When you boot a computer with DHCP to the cable modem it will not be assigned an IP address in the 192.168.xxx.xxx range but if you plug into the router, you will.  If you connect wirelessly to the router you will also get assigned via DHCP an address in the 192.168.xxx.xxx range.  Your computer shows an IP address of 192.168.43.51 I believe with a gateway of 192.168.43.1.  The .43 is unusual.  Still, if the wifi router is assigning addresses in the 192.168.43.0 net then you should be able to plug your computer cat5 RJ45 cable into the back of the wifi router and boot and still get assigned a 192.168.43.0 net address.   There should be more than one RJ45 downlink port on the wifi router.  Plug both the computer and the Jupiter into different RJ45 ports on the wifi router.  Boot the computer, boot the Jupiter, open a browser on the computer and go to http://192.168.43.1, log into your wifi router, go to status, go to local network, bring up the DHCP client table, see what DHCP addresses have been assigned, and there should be two, the one assigned to your computer and one assigned to the Jupiter.  Open putty on the computer, input the address assigned to the Jupiter, open, sign into the Jupiter.  You're home free.

So... 3pm and still no tracking number for my day 2 order. Bitcoinorama, as a spokesperson for KNC I want a statement regarding vouchers and/or early access regarding future orders as an apology for everyone whose order has been shipped late more than 7 days from you, since your customer support seems unable to give non-standardised answers.

I agree an all points.

What I'm saying is unrelated, thou.

Every time your pool stratum request to do the "flushwork" KnC cgminer driver instead of flushing it finish old work and submitting it, this lead to a prompt decrease of your hash rate. And it takes 10 secs at min to climb up to normal level. This happens every time a new block is found (not only blocks found by your pool). The damage get worse when your your pool find a block within a few minutes/seconds from the last "flushwork" request.

Since every reward system is based on the number of shares you submit, independently from your particular reward sys you'll get less btc in the case described above

That was my post on the KnC Forum,

http://eligius.st/~wizkid057/newstats/userstats.php/1FscNBYzd5CqDzUVQ9YapLQNtLbswkM4NL

I had it running for a while on there and didn't touch it until the 12:00 mark.

As you can see it's not looking good.

I've moved them to BTCGuild for now (Just for testing purposes) and it appears 1 of my jupiters is completely dead as well. (Thankfully this was the one that was only pulling around 82GH)

I have emails and phone calls into KnC and they are looking into it. When I get more information I'll let you guys know.

The machine may have been powered on or rebooted just before taking that reading, or maybe its located in a other room or rack.
Whatever the cause, 10 out of 11 (or 11 out of 12 if we include your unit) is not an isolated incident.

The fact that he has one unit actually achieving over 500GH is what is throwing me off and making it hard for me to think it's a data center problem.  It is entirely possible that there are 10's of other customers happily hashing away not participating in the forum.  Without being able to see the error logs, or SSH into the unit I really can't do anything to troubleshoot (other than change pools, which I have done).

Seems unlikely. In the thread you posted on KnC forum, it wasnt like you were the only one. To quote someone else:


Either its a software problem somehow, or they are having serious problems cooling their datacenter and its doing double duty as a sauna right now.

Nah, he's surreptitiously trying to connect to a neighbor's router to run his Hawaii Jupiter.

I've tried both Eligius and btcguild.  I'm currently mining @ 177GH/s (the highest I've seen), without access to error logs I can't confirm that this is my issue. If it was a flushing issue then 1) why are people with physical devices in hand achieve over 500GH when I'm only getting 177? and if it is a data center issue, why does bargraphics have one hosted miner (out of 11) achieving normal 500+ rates?

I really don't think that this is part of a larger problem... I think I just have a bad unit and someone at the data center needs to look at it.  I just got off of the phone with their customer support, heres to hoping that they are able to get ahold of someone to look at it.

most probably that is because of PPLNS reward system. Using this system you must know that max payouts will be reached after 24 hours. thats resist of pool hoping
Also PPLNS means that sometimes it can find a few blocks a day, other time no for a day. Yes, that is more variance accordingly to other reward systems, but in more long period PPLNS miners has higher payouts

And of course it is better to use p2pool to avoid centralized pools fee that is usually 3-7%

1,3,4,6

But depending on which port which hash card.... Good to play with it

mine is mining @490 GH/s and I got about 1.3 a day (it depends on pool's luck)

How many btc per day per Jupiter?
