Thanks Chiropteran. I didn't realize there were so many coins haha. Is Feathercoin really the most profitable right now?
Asicminer USB sticks are down to 0.45 bitcoins in at least one groupbuy. With the new entry of avalon in the usb miner sticks, maybe they will get down to a reasonable cost.
I'm really, really glad I sold most of mine right before the big price drop (for $150!).
I've seen a lot of used 7970's saying its used for bitcoin mining, does bitcoin mining put that much stress on these GPU's that it shortens their life significantly?
Not a direct answer to your question - why not look into middlecoin or multicoin and save yourself some headaches?According to the Where to mine, Memecoing seems to be profitable. Anyone what I can do once I have a bunch of Memecoins?

While I have had very few bitcoin related GPU failures, I've lost two USB hub power supplies already from running multiple USB ASIC on them. Going to cut down to 8 per hub instead of 9, see if that helps.

look at the current requirements on each USB miner. multiply that by the number per hub, then take a look at the DC out amperage available on your transformer. Odds are you're way overloading power brick.
Learn how to follow and read a thread.
The OP specifically asked twice if there was other situations where one hardware vendors cards showed superiority like AMD's apparently do in this.

I love how entire countries like Thailand are outlawing the use of Bitcoin, yet the currency is rallying
what hubs?

Not at all. I did a lot of research, there are dozens of cheap hubs where this is a big issue, but the anker branded hubs are supposed to be fine.
The power supply is rated for 12v 4amp, or 48 watts. USB power is at 5v, and each USB ASIC Miner device uses .5 amps, or 2.5 watts when multiplied by the 5 volts. Even with a full 10 devices on a hub it should only be drawing 25 watts, compared to the 48w maximum.
Interestingly enough, the new hubs have 12v 5amp power supplies, so a little extra breathing room. But based on my calculations even the 12v 4a supply isn't being overloaded. If I can find my kill a watt device I'll confirm power usage.
12V for a USB hub is a very strange number. USB runs on 5V.
I took a look at the manual for the 12V-5A version. they recommend no more than 8 Amp total draw on the USB hub. (8*5 = 40 watts) This is a fairly conservative efficiency estimate of 66% on a 60 amp power supply (12v -> 5v)
Your 25 watt draw is plenty low compared to the equivalent 12V4A version (probably recommend no more than 32 watts pulled)
yeah but I think the psu's are not that good not 12v x 4 as rated but less.
Also I think he has older sticks pre july 8th pull .55 not .5 amps.
Chiropteran when did you order the sticks? pre july 8th? iirc
my sticks are post july 8th they pull .5 amp = 2.5 watts
20 are from the first batch offered at btcguild, ordered July 1st I think?
The other 30 are from later batches. They all look identical, so I am not sure which are from each batch. They all say Rev 3.00, is there a different Rev for the new ones?
How are you planning to run those 50? Are you doing linux/raspberry pi, or are you running windows?
