Mixing Unbuffered and Registered DIMMs

[fightcancer]

According to the manual, this mobo:

Supports four DIMMs of unbuffered DDR SDRAM for a maximum of 3 GB....
Supports four DIMMs of registered DDR SDRAM for a maximum of 3.5 GB....

So what happens if I have 3 sticks of 256 MB unbuffered and I add a fourth stick of 512 MB registered?

Thanks!

I dont have this board.. but typically you can't mix the two.. it'll beep and say no.. but they could have design around that..

I'd be happy to buy it (assuming it will work). Send me the link for your auction please and I'll read your return policy in case it doesn't.

TIA!

Registered is electrically different, I highly doubt you can mix them.
