What voltage do you run? I'm at 1.4Vcore with 433*8 for 3.4Ghz(1600FSB) on my e8200. I've set the FSB strap to 400 MHz and run it at a dropped rate. Some peeps say to set the FSB strap to 333 for a 1:1 ratio, but I cant replicate this.
You should be able to run 3.8GHz easy with a minimal Vcore bump. Whats your ram's voltage @?
