I am on PL9.
Yes, those DDR2-1300 result are bad, can't argue with that.
I will try a everest run on DDR2-1174 5-5-5-15, witch is exactly what you are running. So we can compare it better ok?

I am sure your x38 will still win, but lets see by how much... Also, if the score is close enough, you could lower your cpu at my speeds and run it again, that would be a perfect compare scenario. I am sure I can't push my 65nm B3 to 4.4GHz on air LOL!
