Very Impressive Stilt!

I was running mine ~4.85 @ 1.475v and power consumption was pretty bad...
That's why I decided to try and find a nice balance between OC and power usage.

At stock VID (1.3375), I could get stability ~4.3 Ghz. I never considered underclocking because I use this machine for serious work.
After some tuning and checking bench scores this seemed like the best balance for my uses. Yes, power consumtion is still a little high, but these clocks aren't bad...

This seems like a decent sample (1244 PGT). Next time I get bored I'll see how low I can get it by underclocking.
If it'll get down to the numbers you got it may make a nice server/HTPC chip down the road...
