I don't know, it's your RAM
Depends on whether or not you want to overclock it or not.
250HTT x 11multi = 2.75GHz and using a 166 memory divider your RAM would run at 196MHz sooooo that's using the basis that you want to stay as close as 200MHz as possible, but like I said that's entirely up to you if you want to keep it to 200 or try overclocking it yourself.
If your ASUS there has a lot of memory dividers, then be sure to click the DFI checkbox, all that does is enable the memory dividers that you'd normally see in a DFI bios. A lot of non OC'ing boards though, will only have the options you see in there.
