I know most generic Ram Expansion packs have 2 chips. This one has just one . Looks exactly like the Official one. You can get them from Ebay real cheap.
I have one that's made by Yobo. It has pins for a second chip, but there isn't one there. Can't see if it's a nintendo chip because there's silicon paste on it for the heatsink but you could easily just trim off the top
Interesting. Did they rip those chips off old N64s? More likely they are clones, but why the "Nintendo" labeling? The only people who would open them are modders, and they most of us wouldn't be fooled.
