Has anyone measured the power draw of a Jupiter at the wall? I'm trying to see if a Seasonic X1250 is enough to power 2 of them.

I get 1W/GH/s, dependant on firmware that can be more, or less. Lowest I played with was 0.85W/GH/s in Atlanta, the most I've drawn has been 1.1W/GH/s. That's at the wall.

Personally I would stick to two separate PSUs in case for whatever reason you experience a fault with the PSU, or want to separate the units.

In answer to both yours and the guy above, the Coolermaster V850 is what's being used throughout the hosting, and in the lab, and has run faultlessly the entire time.

It's totally silent as well.

Im pulling on average 630-650w per at the wall all on firmware .98. I would go with what bitcoinorama said- get a PSU per.

Ah, all the new suckers about to sink their money into bitcoin hardware  Cry God bless whichever "you can print money" story which brought them here.

I think sinking fiat is OK at this point, I'm shaking my head at people using mined coins to pay for more rigs from KNC. Its like selling shares in a company to buy more shares in the same company.

I swore I was done with mining hardware. After this runup in BTC/USD, I wanted to take some BTCs off the table. So what do I do? BUY mining hardware.

If KNC is able to ship all by end of november, these should actually make +ROI, surprisingly.

The November delivery machines will probably catch the tail end of the next difficulty change and push it once again. The difficulty jump after that one will probably be in line with what we saw in the last few ~40-50%.

By the end of this month - mid December, Jupiters are going to be earning - what? 0.1 BTC a day? 10 days per bitcoin? 14 days between difficulty jumps? That's not good to be chasing.

And once any of the other asic manufacturers start shipping, we'll probably see more ~40-50% rises in difficulty and that's pretty much game over for Jupiter's. And don't forget KNC China. They did their demo on November 2nd and I don't see where their order numbers are being tracked so people can tell how many they are selling/sold?

Sure you can do the mental compensation "Well, if I earn back 10btc and the price rises to $500, I broke even". Pure gamlbing on btc rising and rising and rising. You might as well just wait for btc to crash a little and buy. But with bitcoin, you never know. But buying hardware pretty much always means you are chasing and chasing.

I don't know that anyone truly realised how much hardware KNC were going to ship in October and the same might be true of November.

40-50% difficulty rise would mean KnC delivers ~4ph worth of equipment in november. They delivered around 2.8ph in october. It will be closer to 25% jump more than likely.

Which will be around .3-.4 btc per day per jupiter

They'd also been taking October delivery orders since early June.

When did they close the window on October delivery orders?

When did they start taking orders for November delivery?

If you think that the network hashrate will be 20PH/s by end of the month you are delusional.

I have a payout from Bitminter that is still unconfirmed after 17 hours.
And I have no explanation why my previous 4 payouts (1 per day) have confirmed in less than an hour, but this one is being treated different.
What changed?

The maximum size of each bitcoin block is limited to 1 megabyte.  This is enforced by the client.

It's up to each miner (which means a pool operator or solo miner) to set their policy for what transactions get included in their blocks.  They can even choose not to include any.

It could be that there are a lot of competing transactions that keep yours from getting picked up, or a lot of blocks are being mined by miners with more selfish policies that don't choose to include [m]any transactions.

Also the network hashrate seems to have stabilized now, so the network is about back to the intended 1 block per 10 minutes, rather than 1 per 7 minutes or so that we saw as the hashrate was climbing.

(This issue would be a lot less severe if we could somehow get rid of SatoshiDice, which spams the blockchain with tons of useless transactions.)

Diversifying off of the big pools can only help... just saying... fellow miners...   Wink

KnC's gen 2 in March? As opposed to a more than half Gh in a few weeks?

AFTER the stragglers have finished delivering half a dozen Ph? As opposed to more than... in a few weeks?
 
maybe...

Wow, I really hope that is no true, because I was contemplating of sending my boards back.

It is a good advice to mark them though.

blockchain.info will refund to the sender after 36-48 hours or so if no miner is kind enough to include it in a block.

Troll much, or are you just misinformed?
You have a different answer?
Please utter it.
2 bashes now on Paladin69, (who was nice enough to answer)
...without ANY explanation....
**** Thanks guys...
I really feel informed now...

The easiest option is to continue to wait.  No, an "automatic refund" will never happen.

The only other option, which requires a good bit of technical skill, is for the sender to manually create a new transaction that spends the same inputs, but also includes a tx fee, and hope a miner picks that one up instead (which will then invalidate the original transaction).

Technically you could say the funds are still in the sender's wallet, but since the transaction has been broadcast, a miner could pick it up at any time and move the funds out to their intended destination address.
That makes sense...
Wish I could add that doggone fee...

Thank you for responding...



The same thing happened to me, but for much smaller amount. I took older copy of my wallet and it got "refunded", it doesn't show this transaction in my wallet now, but is still in the blockchain with 0 confirmations. So, I am not sure whether I have access to all of my balance shown in bitcoin-qt or not.
