I pulled out the old computer chip which I thought was stock but I don't think it is. I put in a red93 chip and it had RN engraved on the plastic, the one i pulled out did too. It also has JT8(G)/p, under that LFIVE 242 under that AF14 these are on the belly of the chip and on top it says APXB with the numbers 3897 under that
