I know that on a non-duel channel board the memory speed will always run at the speed of the slowest memory module installed. My query though is this the case with duel channel boards?
I ask because I have just ordered a duel channel board (an Abit VT7) which initially I plan to get up and running using 2x256Mb sticks of PC2100 from my current motherboard which will be installed in duel channel configuration.
Once all is running well,I plan to buy 2x256 Mb sticks of PC3200 which will likewise be installed duel channel.
However to come back to my question If I leave the PC2100 installed after fitting the PC3200 will this slow my memory speed as it would with a non-duel channel board?
I guess it's a case of 'no one knows'. After all if i had just bought a new Mobo, i might use the old slow memory from the last PC, till the wallet was full again, but ASAP, i would get new fast memory, and ditch the old slow stuff.
