All Ram is not created equal. I found this especially true after my Mac crashed for about the ninth time last night, now refuses to restore my iPod, and won't save anything in Photoshop. It used to be slow as hell, then everyone told me to just upgrade to 4 gig of ram from Fryes, now it just doesn't work at all. I'm totally pissed off.
I'm taking it into the Mac store tomorrow where I'll probably just end up having to fork over $300 on their brand ram. SO PISSED OFF!
