Thanks Jan.  I gave about 50 demonstrations of sending bitcoins at CES and I used your app the majority of the time.  It's very simple and very fast. 

it is also included in the deposit card video demo.  I gave this same demo in person to people all last week at CES.  it is pretty cool when the phone goes "cha-ching" with the text message alert a few seconds after I send the money from your client. Thanks for fixing the 1 BTC minimum.  I had to keep reloading my wallet at the show so I wouldn't run out of money during the demos!

whats this about a "ka ching"?  i just received 1 btc and didn't hear anything.  is it only for sending?

... they're currrently below 90 C...
I have a strange feeling they're not exactly at 50°C...

Anything above 80°C is going to impact the life span of those cards.
What is the "lowest setting"??

Suggestions...
(1) Increase case air flow.
(2) Undervolt those cards as hard as you are able to. This will prolong their life, increase power efficiency, and decrease heat.
     Undervolting is best done one small step at a time, say 0.020 V. If the card is still stable a few hours later, repeat until you've found minimal stable voltage. It will likely differ from card to card.
     I tested each undervolt level for a whole day before going further though it may have been going overboard.
     On my 6770s I've been able to decrease power by about 0.090 (from stock 1.2 downto ±1.110) while keeping the high OC levels (995/300, stock was 800). That shaved off 4 to 6°C per card.
  

sorry to be such a noob about this but i really just got started.

ok, in the AMD vision engine control ctr, there is a Power Control setting slidebar % w/o any units.  i can decrease to a negative %.  would this be the undervolting you're describing?

Overdrive minimum memory clock speed setting is 1375 Mhz. Undecided
That's precisely why I said give MSI Afterburner a try. It's a better alternative to Overdrive, free of charge.
Another widely-used and highly-regarded program is Sapphire TriXX

but cgminer would be your first choice?

what is undervolt anyway?
16064  Bitcoin / Mining support / Re: 6970's on: January 22, 2012, 12:10:53 AM
i'm using AMD Vision Engine Control Center and Overdrive:
GPU clock 900
temp 89C
fan speed 100%
memory clock 1375 Mhz-lowest possible in Overdrive

just started mining so i'm not sure i'm ready to switch from guiminer to cgminer just yet.  i will try to adjust the setting you've recommended.

Some work will surely need to be done:
That temp is dangerous in the long run.
100% fan speed will wear the fans out fast.
1375 MHz @memory is just a waste of energy. Lowering the clocks to 300MHz should drop the temps significantly all by itself.
You might wish to upgrade your PC case with a few good fans. Which case are you using BTW?

I strongly suggest you ditch AMD Vision Engine Control Center and Overdrive and give MSI Afterburner a try.

Yeah, I agree that using cgminer requires putting the thinking cap on and going into the full-nerd mode (also known as text-mode)  Grin
Once you get it working though, it's extremely handy.

They're not supposed to be 50°C, I was just being sarcastic at your vagueness  Grin
Keep'em below 80°C at all cost. Underclocking will help here. High 60s - low70s would be optimal.

If possible, avoid fan speeds exceeding 70%, though.
Higher speeds yield diminishing returns and you'll wear out the fans in a few months.

You said your memory was at the lowest setting. Can you tell me exactly what speed that amounts to?

My previous post has been updated with some general undervolting tips.
All my miners are running Linux and I'm using cgminer for the undervolting. Not sure how it's done on Windows.
I suggest you give cgminer a try. This miner is capable of dealing with multiple-pool mining, overclocking, undervolting, and temperature control all by itself. Not bad for a single piece of code.
If cgminer fails to change the voltages, try AMD's CCC.
If CCC doesn't provide an option to undervolt, you're gonna have to use software like trixx or afterburner.

how do i undervolt?

16068  Bitcoin / Mining support / 6970's on: January 21, 2012, 09:16:22 PM
i'm new to mining but have 2 machines each with 3 Radeon cards, one with Sapphire 6970's, and the other with Powercolor 6970's.

the Powercolors run consistently lower Mh/s than Sapphires.  the only difference i can see physically is the 2 fans vs. one fan.  am getting in the high 200's for Powercolors vs. the low 300's for Sapphires.

what Mh/s should i expect optimally from these cards?  optimal temp? (they're currrently below 90 C).  memory at lowest setting.

using GUI miner, Win7 Ultimate.

am using the recently updated ATI Control Center with Overdrive.  any suggestions?

ok, i understand where you're coming from better.

and in the case of mtgox, where the identity of the owner is known and the fact that he appears to have large sums on certain addresses, what you say does seem prudent.

however, in an individuals case who has taken the time to make an offline wallet and whose address with the large sum can't be traced to him, i think he is fairly safe.
16070  Bitcoin / Bitcoin Discussion / Re: What is the single largest transaction of bitcoins on the block chain to date? on: January 21, 2012, 05:22:18 PM

Likely gox shuffling their reserve around ... odd that they let
it all hang on a single key. Strikes me as a security disaster
in the making.




Or a testament to the security of the bitcoin network.

My comment was not about the security of the bitcoin network,
but about the fact that holding 500K BTC on one key in one physical
location is inherently less secure than breaking it down on - say -
100 keys holding each 5K and kept in separate physical locations.



is it really though?

if only one address gets broken into today, then the whole Bitcoin concept is finished, done, nadda.  yes, as the years grind along, and as faster and faster computers get developed, like potentially quantum, the odds go up that one address can be hacked.

however, this assumes the devs all go on vacation and don't keep up with modifications to the algorithms.  this won't happen hopefully and assuming it doesn't, then its a continual arms race. if you believe the devs can stay ahead of the hackers then you believe in Bitcoin.  if you don't then you'd better just quit now.

in this sense, i believe that one address is just as secure as one hundred.

Jessi,

Loving the tool every day. Alarms have been working like a charm, and gives me a little
more confidence in trading, in being able to properly monitor my trades.

After looking at the calculators I thought of a possible reconfiguration that might be more useful
for everyone. I find myself using the "Last" price-based calculator only. I use it as a gauge to see
what my current trade is worth at any given moment. For now, I do not see any use as of yet for
the Buy / Sell version calculators.

I think what would be handy is having both a "Last" calculator, and a free-form btc calculator,
to compare total dollars at most current BTC price with total dollars based on user-entered BTC price.

That way, one could get an instant comparison between dollar totals based on the live BTC price
and where they think the BTC price might be going, up or down. Also, you could enter in the free-form
calculator, the price at which you bought in at, and then always get an instant  comparison of how your
trade is doing, making money or losing dollars, and by exactly how much. Of course there are many other
uses for the free-form calculator as well,like figuring out BTC trading fees, or re-investing additional BTC
and doing cost averaging, etc.

And the nice thing is, in terms of updating the Alert Tool,  you could simply leave your calculator
entry fields exactly where they are, but make them horizontal equations, with each row being a
calculator.

The Calculator top row would be the "Last" calculator, with the BTC amount entered in the left field,
the "last" BTC price always shown in the middle field, and the totaled dollar amount shown in the
right field.

The second row for the Free-Form calculator works exactly the same, except the user decides and
enters the BTC price in the middle field.

And to make the design even easier, you could simply remove the Bitcoin and Dollar symbols in
between the calculator fields and simply replace them with "X" for multiplied by, and the "=" sign
for equals to, representing 2 horizontal equations, instead of vertical ones. Then on top of the first
calculator column place the "B" bitcoin symbol, the 2nd column maybe "P" for price, and "$" symbol
over third column for total dollars.

Let me know what you think of this idea.

Stew


i use only the last price alarm and calculator.  the rest is just wasted white space for me.

You can use ChangeDetection for email alerts when a blockexplorer.com page changes.

May as well just start doing this and advise others to do the same, it might just catch on.

nice!
16079  Economy / Speculation / Re: Rally starting at 4 pm EST on: January 20, 2012, 07:03:46 PM
Essentially, nothing has changed since January 5, there have been no new net dollars coming in. I see no reason to be anything but neutral in the short-mid term. But if you are long term bullish it is a great time to buy on the dips.

do you measure net dollars based on the mtgox order book?
