Scrypt-Based Mining now is just generally dead. I don't see the point anymore, even if you have Mh/s, you're still losing a LOT with electricity costs.

Some people have access to really cheap or even free electricity.

True, however my single card rig (303KH/s) uses 240W solid when mining. I have it on for 9 hours each day during the night since mining scrypt is so unprofitable ~ at least for me anyway. Its around £9 a month now that I'm doing this minus a couple pound due to my solar panels which are grid tied.

Pick up an R9 270 yo! Coupled with a Sempron 145 you can have a low power single rig pushing 430+ Kh/s and fairly low temps...should be under 175w! Also GOLD rated PSU or better helps a bunch.

Sounds like a plan! Cheers! Cheesy

I had just checked my 3x 270 scrypt rig with my watt-meter and it was pulling +/-550W from the wall (3x 270, Sempron145, 4GB ballistix sport, 2.5" 500GB 7200 WDD Black and a single 140mm case fan) roughly 1.25 Mh/s with sub 70 degree temps and almost no HWE

What PSU are you using? Are they undefvolted or overclocked?

Currently they are on a Corsair TX750 but I am debating which PSU to upgrade to next since the TX750 is only bronze rated...I was running a Raidmax 850AE on my first scrypt rig that I sold and I run Corsair CS750M's on pairs of Antminer S1's.

No voltage changes on any of my cards (as of yet) and only slight overclocking (+100-150 mHz) and NO changes to the memory clock.
