okay, i'm going to be breaking down my current setup and putting in the new parts this weekend and have a question. I just purchased an AMD +4000, MSI Diamond Plus, 2x512 Corsair Value Select PC3200 and an eVGA 7800GT. Now i already have 2x512 Corsair Value Select installed on my machine now. I planned on installing it on the new board and then installing the other two sticks for a total of 2gigs with 4 sticks....all these sticks are the same by the way.

My question is will i have to run this in 2T instead of 1T? If so, will i see a performance loss or will it be a very small loss?

As well, do you guys advise me to build the machine with just 2x512 sticks at first, then after i find everything is stable go ahead and insert the other two sticks of RAM?...just looking for any opinions or if anyone has run into a similiar situation.

thanks.
