can you run a 400fsb processor and and memory at ddr370mhz

I was wondering about upgrading in the future to a athlon xp that has a 400fsb.I have nforce 2 mobo(nforce 2 ultra 400 chipset)and 2 sticks of kingston hyperx 256mb(x2) pc-3000 cl2.I was wondering if I my cpu fsb is at 400 can I run my memory at ddr370(pc-3000) and have it work that way?I know that you can run out of sync,but can you run it that way?

You can run it that way on an Nforce2 MB but it will actually run slower than if you run the CPU synchronously the fastest your memory will go. AMD CPUs/MBs do not run well asynchronously.
