If the center notch is off center, it means that they are not 3 V DIMMs.  I would suspect that they probably look like this...

                                                              5 Volt
UUUUU____I^I_UUUUUUUUUUUUUUU_I^I____UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU
Which would probably make them older unbuffered 5V FPM Dimms.  it's probably a 440FX Chipset.


whereas buffered EDO Dimms look like:
                                                              3 Volt
UUUUU___I^I___UUUUUUUUUUUUUUU___I^I___UUUUUUUUUUUUUUUUUUUUUUUUUUUUUU

and most unbuffered (unregistered) SDRAM looks like:
                                                               3 Volt
UUUUU____I^I_UUUUUUUUUUUUUUU___I^I___UUUUUUUUUUUUUUUUUUUUUUUUUUUUUUU
