2  Bitcoin / Bitcoin Discussion / Physics in Bitcoin (Cyrptocurrency)? on: April 25, 2014, 05:20:10 AM
I was just wondering if there is anything physics related to Bitcoin, or cyrptocurrency in general, other than like the power requirements and such for the miners/GPU's.

3  Bitcoin / Hardware / U2 Antminer USB Hubs on: April 20, 2014, 07:00:49 AM
Hi,

I have looked through the forums and the Internet and couldn't really find a suitable USB hub that ideally won't waste too much USB ports for the U2 Antminer USB miner. While there are some USB hubs that can hold the U2's on all the ports, they usually require the U2's to have contact or have to be clocked at 1.6 Gh/s (I overclock them to 2.2 Gh/s)

I am currently eyeing this one: http://www.amazon.com/gp/product/B00BGT2AP2/ref=ox_sc_act_title_3?ie=UTF8&psc=1&smid=A1HDV7SBYVUV0I

I plan on putting the U2's on those swiveling USB ports and have a fan to cool them.

Since it has been over a month since the release of the U2 Antminer USB miner, has anyone found a suitable USB hub (preferably, USB 2.0, for RPI) for the U2's?

(Yes, I know I won't make a ROI with USB miners, it's more of a learning experience)

Thanks
4  Bitcoin / Hardware / My Antminer U2 default is 1.6 Ghash/s? on: April 09, 2014, 05:28:34 AM
Hi,

When I plugged it in, cgminer displays it as around 1.6 Ghash/s. I thought the default is 2.0 Ghash/s? Yes, I realized I could just overclock it to 2 Ghash/s, but the point is that I think this is somewhat false advertising.

This is where I got it from:
http://www.amazon.com/BITMAIN-ANTMINER-U2-Bitcoin-Overclockable/dp/B00ITD5NV6

Also, on the PCB, it says version 1.2, but on the forums, I read from somewhere that someone had a ver 1.3.

So, did I get a bad chip or is this how it works, that I need to overclock it to achieve the 2.0 Ghash/s?

(I know I won't get the ROI; I'm just doing this to learn more about bitcoin and virtual currency)

Thanks
