I have a rather old motherboard on my desktop, its an asus p5gd1 and max it can take is 4gigs of ram.
Presently i have two sticks of 512mb or ram thats **200mhz** (i got these values from CPU-Z)
I have taken the plunge and bought two more sticks (2 gigs) of ram of 1gig x 2 at *400mhz*
My question is can /should i keep the old ram there as well? or will it be better to just have the newer 2 gigs or RAM thats even running at a faster MHZ, because from my quick reading on google i think mobo's take the value of the lowest MHZ if you mix them... is that right?
I'm confused, is 3 gigs of ram running on 200mhz better than 2 gigs or ram running at 400mhz... or not?
