Only getting 675kh/s radeon 290 on 4.1.271
I get 875Kh/s on 4.0.0 same .bat config

These options are not working with SeriousCoins14 build.
sgminer is not showing the name/temp/fans of GPUs, just blank.
Accepted work unit stats not working, always 0, on both builds.

13.12 drivers Win7 no switch options just pool info.

Those charts watts include the cpu/ram/motherboard etc(system). Anandtech says system 383w full load. I'm guessing the 290 card by itself is 250-270watts.

MSI Z87-G45 Motherboard or GIGABYTE GA-990FXA, 8GB 1600Mhz ram, 8GB USB Linux(BAMT?). 2x Milk crates.

290s 250W/12V=21Amps x6=126Amps
6x 290 @ 250W=1500W
2x 850W PSUs?
Powered risers on cards 4-6
From what I've read here, the 280x and the 290 consume the same amount of power 250-270Watts.
Any gain in PSU efficiency using a 220V outlet?

290   840Kh/$500=1.68Kh/$
280x 750Kh/$400=1.87Kh/$

I've been running a single 290(stock 1 fan) 24/7 for a month now, getting 840Kh(1000/1500 OC) 79˚C 4500rpm in the garage(32˚F).
The better hashrate for slightly more $, seems to favor the 290s, but I can see how 2 fans are better than 1.
So should I get the 280x just because of cooling, having 2 fans instead of 1?

Anyone a reseller with Ingram Micro, Techdata, D&H? Are there prices any better than Pricewatch? Any other sources?
