1) AMD E350, 2GB, 500GB HD, XFX 5870
2) Currently at 407 Mhash/sec @ 970/300 clocks
3) Average 213-215 Watts when mining
Wow that's pretty darn low for being overclocked. The rest of your system is pretty efficient though!
1) AMD Athlon II X2 5200+, 4 GB RAM, 500 GB HD (SATA 7200 RM), 2 x Radeon 5870 @ stock speeds but with memory down to 300 Mhz
2) 702 Mhash/sec @ 850 / 300
3) Average 425 Watts
This is the only machine whose power consumption I've measured.
I've got my main desktop which has a 5970 clocked at 850 Mhz / 300 Mhz memory but for that one I've only measured it's power consumption way back when I had the memory at stock. At the time it was eating up over 500 watts.
I am thinking of taking out 2 gb of ram from the machine mentioned first. I duno if it will make a huge difference in power consumption though, maybe 5 to 10 watts? Maybe not even that. It's DDR2 800 btw.
Neat, I thought my dual 5870's would be consuming more power, but your measurements say otherwise. I don't think memory would make much of a difference, but if you're just leaving that rig to mine you could take out 2gb of ram and it probably wouldn't affect your mhash/s. Though definitely test it out.
