Hot damn I miss that chip!
With regards to efficiency, you're going to seem quite a bit slower than other i7 chips at the same frequencies because you're running dual channel. Triple channel makes a significant difference in 32M.
Try a run with Themes turned on in that XP. Sometimes that helps with efficiency. Also, set Pi to run realtime if you haven't. With wazza... I'm still trying to figure that stuff out lol. Once I do, I'll share.
7 X64 is pretty necessary for Sandra. In XP 32, my bandwidth was 18 GB/s. In 7 X64 it was 28 GB/s.
Interesting, I'll try with themes...
Damn, that sucks because I only have two sticks why is the competition limited to dual channel for x58 then? Is that for latency tests, I could see a single stick pulling ahead there?
I'm still trying to figure out wazza too...
I think if I get really lucky, I get wazza to work, tighten my timings (which are gnar loose in sub), and theme's gives me some effeciency...I might be able to crack 7m while still on water
