Can I use non-ECC memory in a machine that already has some DDR2 ECC memory?

Can I use non-ECC memory in a machine that already has some DDR2 ECC memory?

I have a developer workstation that has registered DDR2 ECC DIMMs already installed. I'm planning on getting some more RAM. Can I add memory modules that aren't ECC and/or registered? I mean, does the machine work with both ECC and non-ECC modules installed? I guess registered ECC memory is at least more expensive?

"ECC and non-ECC can be mixed on the same motherboard if the motherboard does not require ECC. (Funny, I just tried it this morning.) Your BIOS also has to be able to force the ECC to operate in non-ECC.

Do you know if the motherboard requires ECC? What's the model?"

I have heard it will work if the motherboard is ok with it, but it is not advised or recommended by anyone. Using mixed RAM also defeats the purpose of using ECC Ram in the first place though.
