Hello. I have a MSI P6N SLI Platinum mobo with 2x 1GB Corsair CM2X0124 PC 5400 RAM, running in dual channel.
I have recently felt the need to get some more memory, but since I won't be upgrading my mobo for a while, I was wondering what would be best to do.
My question is, can I put another 2GB of memory (2x1GB) on the other channel but of a different spec? That same memory above is becoming a little hard to find around here being old and all. So I was wondering - if I put in some corsair pc6400 memory running at native 800mhz on those 2 slots, would it work? Or would there be memory incompatibility and they'd be gimped running at 667 like the other 2?
Personally, I would retire the old ram and get a 2x2gb kit. The price difference between 2 gig and 4 gig sets is $20 on newegg. You mention that you are not upgradingnthe mobo anytime soon, so why not max out sooner than later? The memory will run slightly slower with 4 sticks in versus 2, and may also affect your overclocking (if you do).
Indeed I was thinking about it. The only problem is that I'm down here in Brazil, so the price for 4 gigs of pc6400 is around 190-230 local.
And it looks like I can't find the pc5400 anymore, so I'll probably retire that memory and stick with this mobo and memory for another 2 years or so. So far the bottleneck of my system is my graphics card, but I can still replace that and stick with processor and decent memory.
