You did not measure them while soldered in, did you? R1 & 2 are clearly marked 7500 and 2401, making it "750 with Zero additional Zeros" and "240 with one additional Zero", at least on that pic of V3 i found somewhere.

I don't know how you came up to 1.16? Datasheet tells Pin 4 is Feedback and should be around .8 V. Resistors R1 (750 Ohm) and R2 (2k4) seem to be the Voltage divider, R2 being the lower part. Calculation is .8V/2k4 * (2k4+750), makes perfect 1.05V for me.
You'll need to replace the 750 Ohms with 1k2 to get 1.2V, 1k giving 1.13V, 1k1 makes 1.16.
Crystal seems to be in 12SMX size, but i can't check, i don't have any Sticks yet.
Questions: - Which size is the Crystal? - Which frequency can be safely obtained (sufficient cooling necessary, but we want max hashpower) - Which voltage is needed for this?
Also, you don't Need two USB ports to power 1A. Buy a cheap hub, they usually have no fuses, just connecting all 5V from the Outputs, the power supply and the incoming cable(!), often making your Computer not shut down properly. All you need is a beefy psu. On the other Hand: if you can resolder the stick to hash faster, you also can resolder the hub to supply more. I plan to Bridge all Outputs and supply with a switching reg capable of 8A on a 10-porter Hub, that should bring enough power for overclocked erupters and maybe for backpowering a RPi.

Sorry, hatte das so verstanden, das 1,04 für Stick und Versand ist. Kann ich den Versand auch in BTC bezahlen, und wieviel ist das dann? Ich hab nicht so viel in meiner Wallet, von daher wird es mit 12 knapp, wenn Versand zuviel ist. Aber sachmal...

How much do i Need to spend for 2 or 4 Units to Germany? It seems a Little expensive at first, but size/power Looks better than any VGA Card. Also, do they work on CGMiner, and how much can be connected to a PC (not power wise, but for example there are only 24 usable drive letters so one can not connect more than 23 usb drives max.).

I have noticed my email adress is visible on the left, below my avatar. How can i hide that? I have checked "hide my email" in the account related settings, but that doesn't work...
Or is it because i am looking at my own account?

Are there problems atm? Hashrate is almost zero, few connected miners/workers, the webpage updates slow and unresponsive, and if it does, the numbers seem off. Although my miners are happily submitting to eustratum. Am i throwing away my shares, or is it a comms problem between web frontend and mining/database servers (again)? Srsly, i really like ozco because of "faith in humanity restored" after the recent troubles, but somethings fishy here... I'd really like a news or shoutbox post giving informations if there are troubles like ddos, even if it's only a link to here.
@veldrik: Those miners (the people, not the machines) have learned that it's best to set up miners and let them run, so they're not watching for weeks (like me) and not notice troubles. Also, i believe companies making good money with mining like asicminer do have an interest in that the pool runs flawlessly, and i think you agree that btcguild runs better than ozco, in terms of ddos-resistance, stats site showing live data and so on. It just feels smoother there.

@organofcorti Yeah, i have seen that. But website and minig machines had connection problems over the last days, so mining was ok, monitoring it was not. Now the site is hacked/defaced/vandalized/whatevs, but what is with mining machines? Do they work as they should, and all will resolve when website machines are back up, or is there a chance that idiot (not Graet) changed mining software and we all work into his pocket? I bet the few people listening to this thread are only a few percent of oz users, most will not see any changes, just because they don't check the website often.
If there is a risk, someone should take the mining servers offline, just like mtred did. So there is no risk anyone loses faith/money/work, and as soon as all is up again, workers will resume to this pool.

@DrG: Every member in the network downloads the whole blockchain. Wallet.dat contains keys, these keys unlock certain data in the downloaded data files, called the blockchain. So, no, you can't get any ip where the coins show up.
Also: My miners still submit to oz. Website seems offline from here, but mining servers seem running. Or am i at risk they mine for someone else??? I'd hate to drive there and redirect them on a friday evening, but if it's necessary.... I hate to lose my small incomes to an asshole more than driving.

@iddo: The amount of almost 100k USD will certainly allow to involve law enforcements, but as you stated: if the thief is in another country, you'll have no luck. And: BTC is no legal currency, so there is no real value connected, no one will help you regain it.
@rupy If you take the law of my country (germany), you as the receiver are responsible to check incoming money for legal problems. It's fake, your fault. You'll lose it to the police, but nothing more. In case of BTC, that is not a real value, so even if they see the thief they won't do nothing. And at least in level two (stolen -> converted, converted -> used) the receiver is totally innocent.
So your "all my further children, and their children, and their grandchildren, follow this mutual adress, find him in real life, kill him and eat his liver, so you will prosper from the thanks of the great Graet" is total bullshit. It's bad, and this dude is a total asshole, a thief, you're right. But you can't do anything.
Assume your wallet (not wallet file, your physical wallet) stolen. Do you have the numbers of your bills noted? Even if: will someone help you get them back? No. As is with those btc. They're lost, get over it.

@rupy: That would definitely kill the anonymity aspect. Who are you to blacklist any address? Law enforcement? No. Bitcoin Administration? Also, no.
So this feature can't be added, because it would let them asses in, blacklisting any publicly available adress from forum posts, "donate here please" and whatever. Would be a nice feature, but the only responsible person to blacklist any adress is the owner of it, and the only use to blacklist is when the wallet.dat gets lost/stolen, as to prevent someone spend the moniez. But then you do not have any information to prove you're the responsible person.
And also, you can't track where these btc's go. That's the way the system is defined. You may be able to see the target adress, but that's an anon value also, so no Name/whatever behind it, at least as long the receiving person doesn't decide to reveal its adress in a googleable way.
Only possible option would be to enforce a new version of any btc related software that allows pool operators to blacklist such transactions/adresses and basically not process them, either as target or source of any transaction. But there is the devil of "law enforcement person". Do you trust any and all pool operators to not blacklist some adresses just because "they're fuckers let's kill them"? I personally don't. Graet and some others are maybe "angels" ("faith in humanity restored" and the like), but i bet there are some bad dudes out there... And you'll only need one to kill the whole system.

Oh shi*, we're fucked. BTCGuild takes over, all Pools are being DDOSed, MTRed closes door, ozco hacked to steal payouts. The System itself has gotten attention of too much people, now some try to get our money out, then destroy it.
And the loss of ~1600BTC, jesus, Graet deserves a gold medal for taking this as a lesson and continue working. Most would have killed someone responsible for this.

Bitcoin / Mining software (miners) / Re: Slight problem with 2.11.3 coming from 2.8.7

... I did not change any settings, just updated the exe. ... What did change from 2.8.7 to 2.11.3 that causes this, and what can i do to stop it? ...
WRONG! Update all files, not only exe. Kill all .bin files. Yay, maybe i told wrong. I exchanged the complete folder extracted from the zip downloaded from ckolivas website. But my settings are stored in the cmd-file starting via autostart folder, not in any conf or the like. I renamed the old folder, extracted the new, renamed the new to not have a version in it, restarted the cmd, cgm ran. But a few hours after that it stopped.
