Title: 6x Sapphire R7 240s ... why not? 635k/hash for under 250w - upcoming BBT Episode Post by: alumar on February 22, 2014, 04:25:38 AM So for an upcoming BBT (Bits Be Trippin) Episode we decided to check out some R7's and see what they could do. These sapphires can be picked up for 35-40 bucks on ebay... for folks with limited power and want to hedge on some doge or other alt coins might be a cheap solution to enter the game.
Machine Build: MB: ASROCK H81 Pro BTC (57.99) ~ at microcenter if in stock, otherwise 150+ on ebay CPU: Intel G3220 Haswell (49.99) MEM: (1) 4gb Cosair Ballistix 1600mhz (37.00) HD: PNY 120gb SSD (Microcenter for 39.99 after rebate) Risers: 5x 1x to 16x (any work, happened to get 5 of them for 40 bucks on the bay) PSU: Corsair CX600 (39.99 microcenter deal) GPU: Sapphire R7 240's (35 each on ebay) ... OC'd to 950/1000 Total system AC via Killawatt - 248w from wall Bottom line: 635k/h @ 140w (just cards) for 35x6 = 210 bucks http://s27.postimg.org/9dkc9pzlv/IMG_1432_1.jpg http://s16.postimg.org/ykwat4p9h/IMG_1434_1.jpg http://s30.postimg.org/hdu1kgr6p/IMG_1435_1.jpg Title: Re: 6x Sapphire R7 240s ... why not? 635k/hash for under 250w - upcoming BBT Episode Post by: NameTaken on February 22, 2014, 04:35:14 AM Will you also be trying Nvidia Maxwell cards in the future?
