So are there really more than one types DDR2 modules? I just got a pair of DDR2 modules titled "HP 4GB FBD PC2-5300 2x2GB Kit". I already have another 2GB module labeled PC2-5300 already working in my machine, but these new modules do not fit in the slots. The cut position in the module is about 3-4 mm away from that of the slot. Any insight?
BTW, my machine is DELL Optiplex 755. CPU-Z tells me that my chipset is Intel Q35 if that is of any help.
UPDATE: Adding a pic of these new modules.
