I have been trying to upgrade my Packard Bell Multimedia R515.  There are 2 DIMM slots and the info I have on upgrading is that it will take 66 MHz SDRAM unbuffered DIMM's  OR 60ns EDO (not ECC). No info on m-board jumpers for different voltages.  Currently has a 32 MB NEC MC-454AD645F-A10 DIMM.

Would a EDO DIMM run at 5 v and require a m-board jumper change?  Are there any that run at 3.3?
Tried a 64 MB SDRAM and was reported at 16MB.  Is there a voltage difference between unbuffered and buffered SDRAM?

Thanks
Dwight
