E8400 and Rampage OC - 1st Time

[sbrown2410]

As the topic says, I want to jump into my first overclock. I am not looking to be overly aggessive, I would be happy to take my proc to a nice and stable 3.6ghz-3.8ghz from the stock 3ghz. I am using an Arctic Pro7 for air cooling. Again, I do not want to risk upping the voltage to high, so that is why I am asking for help here. Can you guys give me some advice on safe settings? So far I have upped my FSB to 400 and raised the voltage to 1.25. My OC is at 3.6ghz I believe. Everything seems stable so far. Also, when i applied my setting, my Ram spped went down from 1066 to 967. Is this normal?

Thanks in advance!

YEs the ram speed dropped as teh divider and strap was changed when you upped FSB, perfectly normal. Try these, leave the settings missing here as auto.(from maximus bios, same board, different chipset, bioses are interchangable)

You can also try to set 5-5-4-15 for ram, some will work 5-5-3-15, test with memtest 2.01.
