Can I use 667MHz DDR2 chips along side 533MHz

[vulcanman]

I bought a Core 2 Duo machine from Dell (Precision 390) .. its on its way here. Came with one 512MB 533MHz (PC4200) chip.

Can I add a 677MHz to it ?

Also ... does anyone know if Dell Precision 390 machines come with buffered memory ?

Thank you.

No replies ... hmm, I take it this is a really dumb question that does not deserve a response ?

1. You can mix 533mhz and 667mhz memory, however, all installed memory will run at the lowest speed.

2. You can NOT mix ECC and non-ECC memory.

3. The Prec 390 comes with either ECC or non-ECC, you will need to look at the BIOS and see what is installed, or look at your invoice/order details online or in your email.
