I have a compatibility question regarding memory. last year I had purchased geil 2gb (2x 1gb) model #GE2GB3200BDC and now I wanted to add more memory. I went to newegg.com and found geil 2gb (2x 1gb) model#GE2GB3200BDCK. All the specs seem to be the same, but the model numbers are off. I wanted to know if I can use the new memory even though the numbers are not the same. I know that you always want to keep memory the same, so I am a little unsure about doing this. Any help would be appreciated. Thanks
