Dram frequency

[Atom1002]

Soo, I was messing around in the bios and I noticed my dram frequency was pretty low. So I bumped it up to the memory frequency thinking that was the memory frequency menu. I clicked save and now my system won't post. My Memory frequency is 3600 mhz so I'm guessing dram is that times 2 so yeah I don't what to do now

i doubt in the bios would give you true frequency, most give the effective frequency.
