Bits Be Trippin Episode 27 covering multiple mining rigs in 4K Follow on Twitter for up to the day progress on builds: @bitsbetrippin Episode Agenda: AMD Pro Duo review 6x R9 390x Sapphire Nitro/TriX 8x R9 390 XFX DD (twin 4x rigs) with newer case design 6x R9 270x MSI Twin Frozr (12" high) 6x R9 280x Sapphire Toxic rig rebuild (Ultra Custom Vertical - BBT) Thanks for watching and subscribing! Please comment if you have any questions! AMD Pro Duo performed amazingly for gaming and rendering, however due to drivers (suspected) it was less than idea performance. We strongly believe this is a 65m/h card if drivers/bios are altered. R9 390x rig featured in episode was a custom rig designed to push 180+ without stressing the cards to hard. Most R9 390 builds that maintain 170-180 have to do it with a high likelyhood of being unstable. With the 390x you get stability at peak speeds, but at a cost of nearly 100.00 per card. Stable settings were 1160core / 1625mem Power usage was 1140 primary PSU, 780 secondary running above clocks; will peak 1200/900 power if 1225/1875 settings used (194m/h) and not fully stable (reboot required hourly) (2) identical build 4x R9 390 XFX DD build in the review is part of a longer term pool payout review, pointing both rigs as individual contributors to different pools, what is the result. R9 270x MSI Twin Frozr rebuild was to test out 12" lengthen on tower struts. Additionally showing old cards still rule on Ethereum both from power to hash ratio. The R9 270 and 270x still do very well. R9 280x Sapphire Toxic rebuild is one for the record books, these crush PoW Ethereum against other R9 280x with the rig averaging nearly 130m/h (common 280's hit 119-121). In addition the custom vertical design/paint and texture are all BBT custom. This rig will go down in the history books as one of the most popular crypto (youtube) viewed single rigs (at least the first most popular). BBT recognizes that and pays homage to building this rare bread of a rig. Settings they are comfortable with 1160core 1675mem Preview of the up coming episode for the R9 390x2 Devil 13 Rig that takes the meaning of bad ass rig to another level. This beast is painted in Crimson Red and boast 12GPU in a single frame. Should be an amazing episode!

BEST VIEWED IN 1080p HD In this episode the BBT quickly covers what were dubbing as the best Cost/Hash/Power combo card out there. The MSI Twin Frozer R9 270 (non-X) This card is a absolute BEAST ... mid 450's scrypt hash for 209 bucks, uses only 145-155w of power and only has 1-6pin connector! You can save a fortune when placing 6 of these in a mining rig by only using one PSU! The advantage of only needing 1 single 6pin Rail is monumental!
