Sorry, didn't mean to be hasty. In _my_ experience with ~150 transactions, it's never taken more than 30 seconds. In fact, I'd bet 1BTC it's never taken more than 10 seconds, for me.

With that said, I am sitting on a 20M downstream connection on a dedicated bitcoin machine running no other processes.

Your mileage may vary. Results represented here are not typical. Stunts performed on a closed course by professionals. Do not attempt. No animals were harmed during these transactions, blah, blah, etc. 

In most cases you are correct. However twice I've had it just sit there and do nothing after restoring a different wallet to a machine that had been using a different wallet from what I just restored. Rescanning fixed the issue in both cases. They didn't write the code and implement the command switch for nothing!

30 seconds, if that.  Of course, it shows up unconfirmed and took a while to get confirmations and my balance to reflect the deposit. But the transaction itself should show up almost immediately.

ITT: People who have no idea how markets work, but came here after reading mainstream media and thought they could print money.

A lot of you should invest in CD's or just regular savings accounts with a set interest rate, so you're guaranteed a return on your investment. With BTC, just like stocks, you could wake up tomorrow a millionaire or flat broke. It's the risk you take playing the markets.

Open a command prompt, and change the active directory to where bitcoin is installed, which varies by OS. For example, on Windows 7:
then execute bitcoin with the rescan command line switch:

At this point the bit client will open just like you clicked the icon, except it will start downloading the block chain and your transactions will start to appear and be confirmed.

It's not OS sensitive, at least between Windows and OSX. I routinely move my wallet between the two with no problems. You just need to download the block chain again once you restore the wallet on a new machine, which may take an hour or so, depending on your connection speed.

If I move my wallet from OSX to Windows, I simply run "bitcoin.exe -rescan" and all my transactions start appearing as the chain is loaded.

He asked about the risk, not about how to recover from said risk.  But you're right, so I'll rephrase...

The risk is rendering your card useless unless you have the appropriate hardware on hand to overcome a bad flash.

Hey, if you and your boss have conspired to steal your employeer's power and you both can sleep at night, more power to you (no pun intended). No need for you to worry, the rest of us tax paying citizens will surely make up for the losses your company write's off each year.

Current is delivered upon demand. a 450W PSU doesn't always draw 450W. That's just the max it can deliver under load. 80 workstations running full-tilt for a sustained amount of time will add a noticeable increase on next month's power bill. If you're the one ultimately in control of those 80 machines, all fingers point to you.

I'll still have a job on Monday.  You jelly?

Best post today.  Check your wallet!

Over 9,000 Ghash/s.

MSI Afterburner allows you to select each card, and make changes to that particular card independent of other card's settings.

I'm running a 5850 and 5830 on Win 7 64 bit and have no problems setting each card independently.

You will need either a dummy plug, run both cards in crossfire, or connect both cards to a monitor in order for Windows to recognize each card as active.  On my particular miner with this setup, I have one monitor with both VGA and DVI inputs, and just have each card going to each input.

Hope that helps.

No.

There are several threads in this forum on it using various ways; Using WINE, using FreeDOS on a bootable USB stick, etc.  Just poke around.

The risk is bricking your card if the flash fails for whatever reason.

More or less, yes.

Browse through the first 2-3 pages of threads in this forum. This issue is hashed out almost daily.

Mineing requires pure computations; theres not a lot to store in memory. Under clocking your memory reduce heat, which allows you to over clock the GPU even more without your temps rising further.

As far as flashing, the quick answer is you'll need windows. You can install WINE, the windows emulator, and run a windows application within Linux, but it's risky. If it fails during a flash, you can brick your card. There's a thread here somewhere about booting off a freedos USB stick, grabbing the bios, putting the USB stick in a windows box to edit the bios, then reflash via freedos again to flash the card. probably your best bet.

It's over guys, it's all over. By midnight it'll tank and be at $0.

Please send all your BTC to the account in my sig. All I want is a huge cache of worthless BTC to give to my kids in 20 years as a keepsake reminder of the first run at a decentralized cryptocurrency. If the market happens to rebound (and I promise it won't), I swear I'll return al your BTC. Scouts honor!

Exactly.  Mining needs raw GPU computations and doesn't need to store a lot of data in memory.  By downclocking the memory you reduce the heat, which in turn [may] allow you to increase the core clock a few more MHz and stay at the same heat levels.  It's all a balancing act of gpu clock, memory clock, temperature, and Mhash.

I could be wrong, but I believe the 6870's consume more power than the 5830's. So they may preform about the same, but you'll pay more in electricity for the 6870's than the 5830's if that's the case...

Agreed, but there are the loyalists out there...
