The memory chip I got is still wrong. The problem now is that the center notch is off by 3 or 4mm, however the voltage notch is OK.
The 2 notches in DIMMs are for voltage, and for buffering.
The one on the far end is a 3 position key. RFU(??), buffered, or unbuffered. The middle key is the voltage. It is either 5v or 3.3v. Perhaps you got the wrong voltage DIMM?
Further research reveals it is MAC memory, ie; DIMM's used in several of their server lines. We took the original unit out of the ARC (which had an IBM part number on it) and cross referenced it, came up with the MAC compatibly listing.
That actually makes sense, since the ARC is a PowerPC 603e... So, not proprietary, just obscure. :) (Apple on the other hand uses standard PC100 and PC133 dimms now, I have some acme generic PC100's in my G4...)
