I't not so much a phantom chip, but the specs just aren't right for the mac it reports to be. Because, well... it's not a mac. When my much loved 2008 MBP needed replacing last year i decided to go with a hackintosh, as much as i would love another MBP their just way out of my price range
It's really a Acer E1-571, It's a nice enough laptop but the build quality just isn't the same as the MBP (about one year in i have already replaced the DC socket, i'm on my second charger (but thats about the same rate as the MBP went through chargers) and last week i had to epoxy the left hinge mounts back in)
