I have been having problems with my memory. I can only get it to work at 800mhz instead of 1066. I am thinking that I got some bad memory or something along those lines. How does getting it replaced work? Do I send mine in and then wait for the replacements to come. Or, do they send me the replacement and I send mine to them when I get it. I think that it would be the first one but I hope for the later. It would suck to have to shut my computer down for 6-8 weeks while I wait on the replacement.
