Got kernal panic, ran Hardware test and got above error. I have the 2 factory chipsets in + 2 PNY 256mb chips. 4 total. I look at system profiler and the one labeled J14 appears to be the last of 4 causing the problem right? So, I went back to COMPUSA and got the replacement. Added it. Ran Hardware test and got this error; 2MEM/5/4

IMM3/J14. I thought; "there can't be anything wrong with the Apple RAM" so I swapped the two PNY chips thinking if I got an error it should be J11 this time right? Nope. After swapping the two PNY chips top to bottom and bottom to top and ran hardware test it showed; 2MEM/2/4

IMM3/J14. Have I been addressing the wrong chip the whole time??? How do I know which chip is which? Is the J14 bay bad? Will not any chip work there???
