Didn't know where to put this, so if this is the wrong place then i apologize. I just bought some ram and realized a slight mis-calculation lol .... the ram i have in my system now is 2x 512 sticks for 1GB but the ram i just bought is 2x 1GB sticks... NOT 2x 512 sticks, does it make a difference??? Other then that its the same ram type and speed. IF the sticks will work fine together am I able to still enable dual channel in all four sticks even tho two sticks are 512 and the other two are 1GBs?? thx for any info!
