Most of the 128 MB SIMMs sold in last 5 years here on Amibay are with 3.3V chips and just recently someone made HOAX about it. Of course it worked well in Rainbowat's B1260, just like mine 3.3V SIMMs in my B1260 and BPPC. Please STOP spreading this hoax, most of 128 MB SIMM owners has 3.3V version and I never heard of any problem caused by SIMM voltage.
