My 2GB Crucial PC2-5300 SODIMM arrived today. Thanks, newegg!
I replaced the original 1GB SODIMM in my MacBook Pro with it. So now my MBP contains a 2GB Crucial SODIMM ($115) and a 1GB Crucial SODIMM ($25 after rebate, $45 before). Boy, does XP Pro run nicely in Parallels Desktop now!
The big reason I bought this extra gig of RAM was to run parallel XP Pro and XP Home virtual machines in Parallels. With just 2GB, my machine went absolutely nuts trying to do this. Now it works great — it’s one of the first things I tried.
