Question : Problem: Slow memory clock speed.

I have an AthlonXP at 333mhz.  I also have 256MB DDR RAM at 400mhz.  My mother board supports DDR 400 memory and FSB but my memory only runs at 333mhz.

Is this because my CPU has max FSB at 333mhz? Can it be fixed?

Would over clocking the memory only do bad things?

Answer : Problem: Slow memory clock speed.

It is always best with AthlonXP's to run the memory synchronously with the cpu bus.

There are some motherboards that allow you to clock them asyncronously, as you've tried to do, but some don't.  Even on those that do allow asyncronous operation, it's been proven in many benchmark tests that the performance actually WORSENS if you run asynchronously.

Also of note, many people with boards that do allow asyncronous operation have noticed more errors / crashes trying to run this way.

So #1 problem is performance worsens, #2 problem is more frequent crashes/errors and #3 is some boards just don't allow it.

All - in - all, it's just not a good idea.

If, however, you get a 400MHz cpu, you should have no problems running both at 400MHz.
