I've got an iMac 450 DV+ with a non ECC SDRAM module in it. Can I add an ECC SDRAM module to use together with the non ECC one? Or Do I have to uset either type rather than mixing them?
In the old days ECC used to have a couple of extra pins on it, if that is still the case then you may not even be able to put it in. (This is PentiumPro era info so salt to taste.)
