Moin,

muss doch mal bissi meinen Trust hier erhöhen:

also biete ich 33x USB ASIC Eruptoren !

Insgesamt 33 USB Eruptoren mit 333-335 MH/sec für 3,5 BTC das Stück. Gerne auch einzeln.

Porto innerhalb von de übernehme ich. Versand als versichertes Paket bis 500€.

Bezahlung in BTC, Euro oder Paypal, gerne auch mit Esrow (WechselKurs gilt MtGox Weighted Avg €)

Bei Interesse bitte PM oder hier antworten.

8/36 verfügbar:
 - 25 x  anderweitig verkauft
 - 03 x für topvmax (bezahlt und versendet)

bzgl. der technischen Daten:

The first mass production batch (sapphire) has finished its PCB production and assembly today.

It has significant improvements in:

Heat reduction: 560mA (emerald) -> 500-510mA (sapphire).

Stability: We stressed it with 9 Block Erupter USBs in a row without heatsinks heating up each other in a very dense USB hub with 25C without active airflow. No unexpected (non-probabilistic) HW errors ever happen.

Speed: This comes after better stability. Now the hashrate converges to its theoretical value of 336MH/s.

Appearance:
  Manual assembly (emerald) -> SMT machine assembly (sapphire)
  Standard heat-sink (emerald) -> heat-sink front-case 2-in-1 logo-ed (sapphire).
  LED added.

Four types of front-case:


All of them are eager to be powered up and hashing!


Anleitung von yxt zur Inbetriebnahme:
Linux users should not need any help.
So here for the win users only:

  • download latest cgminer-3.1.1 :
    http://ck.kolivas.org/apps/cgminer/
  • install this driver:
    http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx
    no reboot required
  • plug in the usb miner, wait few seconds
  • search in the Device Manager for:
    Silicon Labs CP210x USB to UART Bridge (COMx)
    keep the COM number(s) in mind
  • start cgminer with the following arguments:
    cgminer-nogpu.exe --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S COMx
    for more than one device: cgminer-nogpu.exe --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S //./COMx -S //./COMy

happy hashing  Smiley
But be careful! they get hot during operation! I recommend cooling. Direct some airflow over the heat sink.
