Topic: Tip: 270 "non-x" @ 490Kh/s = 0,33W / Khs - page 2. (Read 2917 times)
on my 270 from powercolor on windows i can take 475 max with same settings, except clocks 1150/1500 and th - 24000
I've lurking around for making my mining rig. Especially R9 270's have my interest.
Your topic + pics of the rig got me intriged.
I guess you undervolted the 270's. What made you do this since i saw this voids the warranty? Or can you just put the original bios back up there and they can't see it.? What where your steps here (vbe7 and cryptobadgers guide)? What voltage seems to be completely stable?
I was thinking of using 1 platinum 1200W psu on bamt, no hd, cheapest intel sempron cpu. Think this would pull it off ok?

280X still better price/performance
Stop talking nonsense. This card costs way too much and doesn't offer a performance increase by the same factor. In addition to the 270(and x version) being more energy efficient (plus only 1 cable). 280X still better price/performance
How is that? the 280x isn't twice as fast yet it costs twice as much.
280x MSRP is around 320 - 350. So not 2x as much as 270. Also KH/Watt is better on the 280x than the 270.
Not in the US. Cheapest 280x available at newegg is $499. There are some of the lower clocked 280x's at amazon for $469... vs. 270's @ $200-229
Last week you could've had most 280x's for $400 easily. This week the lowest I'm seeing is $449 from reputable vendors. Prices do fluctuate. But the KH/Watt is still much better for the 280x than the 270.

Just wanted to share my latest rig that turned out pretty well after some tweaks.
2940Kh/s @ 975W (Whole system)= 0,33W / Khs
Compare to my other rig with 3x280x
2160Kh/s @ 910W (Whole system) = 0,42 / Khs
I belive the 270's "non-x" are great value right now, u can squeeze almost 500kh/s (475-490) from them for ½ price (210$ in Sweden with BF4) of the 280x (385$).
My kill a watt-adapter measure's values from 940-980W @ wall on 100% load. I downclocked the CPU and no connected fans.

Settings? I can only get 423khash stable with my 2x 270x's
