does otp406 support ddr3 1333 memory

[asjank]

I have Dell studio xps420 q9450 4 gigs ddr2 667 latest ao7 bios.32bit vista home premium.
Am planning to upgrade to windows 7 home premium, 64 bit, add some storage and increase memory to 8 gig.
Getting conflicting messages as to which type of memory is fully compatible with proposed system.
I know that staying with ddr2 either 667 or going to 800 will be fine. My confusion lies with whether I can upgrade memory to ddr3 1066 or 1333 ( strictly for future proofing purposes) and still get that memory's full functionality? I have seen conflicting info - some saying ddr2 800 is upper limit, elsewhere that ddr3 is ok. Most recently a Dell techie was telling me to upgrade my memory to 6 or 8 gigs using ddr3.

Looking forward to your input(s)

thanks, AJ

It can't be conflicting as you just can't use DDR3 memory in a system designed for DDR2. Maximum speed is DDR2-800.

Thanks - this is what I thought, but needed to clarify

If interested, you can use CPU-Z to verify what memory modules are currently installed. They most likely are DDR2-667 (333 Mhz).

sorry to step inside but I have the same pc and wanted to up grade it so I wonder if it will be possible to change mobo and if yes with what? I know my mobo is OTP406 with Intel X38 chipset
