still using btc guild and thinking should i change to Eligus
any idea?

idea - lets go to p2pool

Anyone mines on P2Pool?

many ones  

have i have some suggestion of P2pool? i have about 1500ghs atm

find some suggestion here - http://elizium.name/faq.html

KNC products don't work well with p2pool.  They didn't design work restarts properly, you will lose a lot of work and money.  If you have a KNC product, and want to use p2pool, contact them and ask them to fix it.

you're referring to this https://bitcointalk.org/index.php?topic=18313.msg3294238#msg3294238 right?

it is quite annoying also with normal pool that work with stratum. Everytime a block is found you got this on your cgminer:

Code:

 [2013-10-09 19:42:36] Stratum from pool 0 detected new block
 [2013-10-09 19:42:36] KnC running flushwork
 [2013-10-09 19:42:36] KnC: accepted by FPGA 1 works, but only 0 submitted
 [2013-10-09 19:42:36] Rejected 00815da7 Diff 506/326 KnC 0  (Job '26017' not found)

and your hashrate promptly decrease and it takes time to climb up again to normar rate.

it also happen with i use btc guild
but it wasnt decrease too many work i think

sure you're right it's not that the hashrate fall down to zero and stay there for 10 mins.

it's a lot less problematic than this.

the problem is that it happens not only when your pool find a block, but every time someone find a block, be it one of the million active pools or a solo miner. this happens quite frequently.

edit1: to get an idea on how frequently a block is mined look at https://blockchain.info/blocks

Got a tracking number this morning for my day 2 Jupiter paid on June 10th. Package has not yet arrived at the UPS facility but is scheduled to be delivered on the 16th to the US.

Whoa whoa whoa whoa. Wait, day 2 is not a June 10 paid order, someone correct me?

I paid the 9th and am not a "day 2 order" - on top of that i'm still sitting "in progress".

"Shipping in order of payment my ass."  

It has been said time and time again,

Day 1 and 2 are from the Original Queue, you get to hold your "Pre-Order" spots.

Everything after (and maybe some day 2 slots) are on shipped based on payment order.

This is not something new. Has been known for months now.

I just got my tracking number (label printed is the stage it is at). My order was not day one nor day two, but paid on 4th of June.

If you're not happy with your purchase, I would contact them and ask for a refund. Do not automatically file a charge back without first contacting them to resolve any issues you may have. As chargebacks can affect the merchant account negatively. It not only costs the company a chargeback fee but also it goes on your record.

They repeated ad nauseam: "no refunds!"

sure you're right it's not that the hashrate fall down to zero and stay there for 10 mins.

Actually this happens about every 10 mins, well more like 7 with the hashrates lately, on a regular pool or solo mining.  P2pool issues 30 sec work, so the effect is much greater.  It would still benefit all miners if they handled work restarts more efficiently, and every little bit helps with current hashrate increases.  I think it flushes when new diff work is sent also, so setting a static diff on the pool helps, instead of letting the pool adjust the diff.

got tracking number today, #16xx paid 10th June day 2

[Bargraphics]

Alright. So did Day 1 and Day 2 customers get more than 7 days to "hold their order" spot and pay later and still be ahead of others? (me)

This I am unsure of, I know they definitely had a set period of time to pay in order to hold that position. From what I recall there was a little drama over the way this was handled but that passed.

I believe it was only 7-10 days to make a payment (something about wire transfers etc...)

June 10th was the last day to pay and still hold your pre-order queue spot.  Once all "Day 2" orders are processed, it is strictly by pay date after that.  Order number are irrelevant btw.  People should be posting their "pay dates" as they get tracking numbers so we can see where KNC is at in the queue.

For the record:

Order #17XX - Paid on 6/9/13 - Status: In Progress (over a week)

With generic reply when asking about this (last week, reply recieved today)

We are working through the order queue as quickly as possible based on the payment dates of the orders. As soon as your order is fully produced and shipped a tracking number will be sent to the email address which was used to register for your account.

They held off shipping to fix the "Caps blowing" issue. Your unit was likely getting assembled when they made this call.

Haven't heard many more stories about the caps blowing other than Anti-KnC people claiming the boxes blow up and cause nuclear fallout (lol) so shouldn't be much longer.

I paid June 25 and went to "In Progress" several days ago. My guess is that they just set all orders that were supposed to be shipped out by the 15th to "In Progress". Does anyone know what the pay date is of the orders that are being shipped out now?

It appears they are still working on the pre-order queue. Once they are finished with the day 2 orders they will start working by pay date. No one has confirmed a tracking number past a day 2 order yet.

I have orders that are supposed to be delivered by the 15th but they are not even in-progress yet.  My guess is that in-progress means they are building your unit. They are likely building them in order by pay date.

With the skyrocketing hashrate, the need to have a huge miner farm to mine effectively, and the excessive cost of  miners, one might compare such an investment to buying a Segway to collect deposit soda cans off the roadside and expect to pay off the debt faster than interest on the loan needed to buy the Segway.

I have, my previous post. I am not day one nor day two, but paid on the 4th, and I got my tracking number now though its stage is only that the label has been printed the item is ready for UPS to go pick it up.

Awesome!  Looks like we are finally past the pre-order queue and working on June 4th pay date.

Borrowing money to buy a miner would be the height of foolishness.

Yes, and it's the power supply's fault - or is it?  Designed to have a motherboard connected to the motherboard connector; a simple 2 pin jumper is commonly used instead; startup current is ramped up until voltage is attained; capacitors charged from a voltage take 5 time constants and 70.7% of the voltage is reached the first time constant so it way not linear but charge a capacitor with a constant current source and you get a perfectly straight charge plot right up to full voltage so a constant current source is used to charge a capacitor creating a linear ramp that they track increasing the output voltage until it's at the required voltage.  That capacitor charged from a constant current source does not have to reach 12 volts or even 3.3 volts, it can be a ramp from 0 to 1 volt and can be tracked to control the ramping up of current on the 12 volt line.  If the ramp is a capacitor charged from a constant current source on the 3.3 volt line, which has no load output load on the 3.3v line because a jumper is used on the motherboard connector and only the 5 volt and the 12 volt power supplly lines are used, then when you shut down the power supply and disconnect the connectors from the miner, the 3.3volts might remain on the 3.3 volt line of the motherboard connector and it the discharge of the capacitor with the ramped voltage depends on the 3.3v rail going to ground to reset the power supply wake-up 12 volt ramp current, then it's possible to plug that supply back in, flip on the on/off switch and hit the miner with un-ramped current, full current at wakeup, on the 12 volt line and in that instant the voltage goes way beyond 12 vdc.

Depends on your expected return and the "strength" of your prediction.

They can take a power supply, a 2 pins jumper, and a test miner, add 3.3v to the 3.3v line on the motherboard connector with a couple of AA batteries, run the miner, shut it down, disconnect the turned off miner leaving the 3.3 battery volts between the 3.3v and ground on the mb connector, reconnect the power supply to the miner, flip on the power supply and look to see if a miner capacitor goes BANG.

Hell, if I were in the lab I say build a test rig with a peak detector on the 12vdc line and the battery 3.3v on the mb connector the test one of every major brand of power supply to see what the restart peak is on the 12vdc line.

Anyone amongst saturns owners  would mind to check beagleboard system load using uptime command from a ssh session?

I have a theory that implies that the lower perf someone get on jupiters configuration is also due to some "bugs" present in cgminer driver developed by knc that makes the system waste resources in I/O waiting.
