Does this mean the 400GH/s kit can made to easily go up to 640GH/s? What's required to do this? Changing some resistors and crystals?
1382  Bitcoin / Mining speculation / Re: Will August bring an additional 200TH? on: July 19, 2013, 12:21:31 PM
What about BitFury devices not destined for 100TH? I remember seeing at least 60 units of Megabigpower 400GH/s August delivery kits available for sale at one point.
1383  Bitcoin / Bitcoin Discussion / Re: U.S. bank closing all of my deposit accounts because of bitcoins on: July 14, 2013, 10:38:26 AM
I recently spoke with someone who works as a compliance officer at a large bank (in the US) regarding this issue. She basically told me that accounts that move a lot of money in and out of the country automatically trigger alerts that put them into the so called high-risk category. These accounts then need to be kept under closer tabs, as in someone needs to manually track subsequent suspicious transactions and either file Suspicious Activity Reports or record down the reasons why the bank thinks that the transactions are not suspicious after all. (This could be as simple as someone from the bank calling you and asking you what these wire transfers are all about and then adding your response to the file.) Failure to do so could result in heavy fines against the bank. This is a lot of work for the bank, so at some point the bank just closes these troublesome accounts if they feel that the revenues that these accounts bring in do not justify the costs required to maintain regulatory compliance.

This is true for both personal and business accounts, but the handling of each is different.

Is there anyone who tried except with watercooling to mod their unit to be less noisy? Maybe like try other fans or such? The noise is driving my kids crazy and I didn't think they could get crazier. Proofed me wrong...  Embarrassed
My batch 2 unit was definitely noisier than my batch 1. It seems to me like my batch 1 unit was dissipating a lot more heat through the bottom aluminum plate of the case, thus requiring less work from the fans. The bottom of the batch 2 case was a little warm whereas the batch 1 case was almost too hot to touch.

The batch 2 heat sink is of a different design and has small ridges on the surface that mates with the case. This reduces thermal dissipation through the bottom of the case.

I made my batch 2 unit a little quieter by applying Arctic Ceramique 2 between the heat sinks and the case. I needed 3 x 2.5g tubes - one per hasher.

Edit: I used Ceramque because it is non-conductive. It is easy to make a mess while screwing the heat sinks back to the case because the holes are not easy to align.

Thanks for clearing that up.  I hope Tom didn't rub off on him. 
If you were a credit card customer of bASIC, you'd probably have no qualms placing an order with Dave. No SSL cert? Just use a virtual account number and close the account once the transaction posts.
1386  Bitcoin / Hardware / Re: 3D Printed Block Erupter Coffee Cup Warmer on: July 06, 2013, 01:30:55 PM
I had an old USB-powered soda can cooler, exactly like the one pictured below:

http://www.ign.com/articles/2007/08/09/coolit-systems-usb-beverage-chiller-review

Under the cold plate is a peltier device and a heatsink. It did a poor job at cooling soda cans.

I have since gutted the peltier device and heatsink and replaced those with a Block Eruptor. I also had to replace the cable with a proper USB cable. Let me tell you that it does a worse job at warming coffee mugs than the original cooler did at cooling soda cans.

Sorry I don't have pics as I left it at the office.

In any case, this experiment convinced me that 2.5 W is not sufficient to adequately warm a coffee mug. Maybe 2 or 4 Eruptors might do the trick?

There are lot jala box and labes pictures you can check if they got CE
The only CE logo that came with my US-delivered Jalapeno is the one that appears on the power supply.

If hardware can not be bought off the shelf for next day delivery then it just makes the entire mining game and ELITIST business just like the banks.
And if hardware could be bought off the shelf for next day delivery, then most people would not bother to mine because they would only be earning pennies on top of ROI.

Don't worry though, the day will come when ASICs become a readily available commodity. Once that happens people will be spending their resources searching for other things, such as cheap 0.02 cent/Kwh electricity.

That argument is so flawed - so no one was mining bitcoins until ASICS became available? So what were people mining with back in 2008? I think you will find a great deal more people were mining Bitcoins with off the shelf hardware than they were with ASICS for the past 5 years.

When ASICs become readily available you will have to spend $100,000 on hardware just to have any kind of decent profit. I don't know many people accept for large businesses that will throw $100,000 at hardware so kind of putting it in the elitist territory.
I am willing to bet that are more people mining with ASICs today (including USB block eruptors) than there were CPU miners in late 2010.

That wasn't my point though. Mining will always be competitive and the so-called "elitists" will always control the hashrate. For example, in early 2011 when GPU mining was very profitable picking up ATI 5870's and 5970's were is short supply. People like Vladimir who had direct access to a hardware distributor cornered all the available high end GPUs and built his giant GPU farm. Other people like myself were left with low-end 5830's. (I still manged to mine over 1000 BTC with 8 5830's in the spring of 2011).

Why would you buy paper metals?
The analogy is not correct. The AM shares pay dividends in real BTC. As far as I know, paper metals do not pay you any real dividends (though some generate taxable artifacts and report those as dividends).

Wiring to BTC-e is easy now, but it's prohibited for US sitizens.
I was not aware of this. Where exactly can I find this information?

What about wire out to the US?

I bought a bunch of these to support the p2pool network - at a loss, but so what? It is my BTC, not yours.

These actually run p2pool very well with not too many stales. So does the Jalapeno, but these aren't readily available.

My Avalon cannot run p2pool as it generates a shitload of stales.

Careful, the PCI-e riser is only rated by Dell for 25W or 35W, depending on the configuration.

A year ago, I shoehorned HD 7750's into some Poweredge R710's and I burnt out one of the PCI-e risers. These were rated for 35W.
1396  Bitcoin / Hardware / Re: What USB hub should I get for USB miners? on: June 28, 2013, 01:50:42 AM
For me cgminer 3.2.x and higher (running in raw USB mode) has intermittent problems with USB block eruptors on the Anker hub. A device would randomly zombie out, and suddenly reappear as a new device. Shortly thereafter cgminer would crash.

However, cgminer 3.1.x which still communicates with Icarus devices in the serial-USB mode seems to run just fine. I am guessing that it is only a matter of time before this gets sorted out.
1397  Bitcoin / Hardware / Re: [ATTN] Is there anyone still not receive your batch#2 machine or tracking #? on: June 26, 2013, 12:46:35 PM
For what it's worth I've just received an email with a tracking number for my Feb 03 order. There is really no point in aggravating yourself if there is little more that you can do about the situation.
1398  Bitcoin / Pools / Re: [POLL] Why don't you mine in p2pool? on: June 25, 2013, 11:47:32 PM
ASIC manufacturers seem to only consider p2pool as an afterthought. They seem to like coming up with optimized designs that achieve increased hashrates by delaying the reporting of shares by a few hundred milliseconds or even a few seconds.

And by the way: is store-avalon-asics.com the same as store.avalon-asics.com?
Can anyone check if you can login with your verifying credentials at both sites?

I wouldn't do this if I were you. It might also be a phishing site. The last thing you want to do is give them your credentials to the real site - they might then try to change your delivery address.

Firmware with overclock binary:

http://downloads.qi-hardware.com/people/xiangfu/avalon/next-testing/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory-20130622.bin

It is not exported to the web interface so you will have to manually edit the /etc/init.d/cgminer configuration

Thanks!

changed this -> in /etc/init.d/cgminer

Heh! Just remap the 256 MHz and 270 MHz labels with the 325 and 350 params. It is not like anyone was using the 2 lowest speeds anyway.
