Title: WTS BFL Jalapeno's 6 chip Mods 25gh each (free shipping USA only)
Post by: terrapinflyer on March 27, 2014, 07:53:02 PM
Im looking to sell my two 6 chip modded Jalapeno's. Each pulls 25gh and about 100w from the wall (Typically the unit pulls around 10 watts and each chip pulls 15 or so. Thus a 6 chip unit would pull about 100 watts.).
I would like to get $235 usd for the two units, 700w psu and the avr dragon programing board.

Includes 2 6-chip jalapenos (https://bitcointalk.org/index.php?topic=336782.0), AVR Dragon programmer (http://www.digikey.com/product-search/en?x=0&y=0&lang=en&site=us&KeyWords=avr+dragon) (with USB & 10 pin parallel cable), and a thermaltake TR-700 power supply (http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=TR-700&N=-1&isNodeId=1).

All mods were done by Brassguy (https://bitcointalk.org/index.php?action=profile;u=59905). Replaced the resistor (R11) with an 8.2K to overclock the asics. Heatsinks are installed on all of the mosfets (top and bottom). Copper thermal shims cover all of the chips because the original heatsink doesn't cover the added chips completely. The original cases where used to create a wind tunnel to keep the mosfets cool (they are about 100F as I'm typing this). The original fans were replaced with higher airflow fans and actively cooled heatsinks were added to the bottom (not attached). Cool and stable  ;D

Price included ups Flat Rate shipping to the lower 48 (USA only)

I can offer you .35 if shipping to the EU isn't too expensive.
