Universal 3.3V VDIMM Mod
@ 2004/08/16By default, conventional DDR SDRAM operates at 2.5V. Most motherboards max out the Vdimm voltage at 2.9V. Abit’s AN7 and high-end DFI motherboards are just a few of the exceptions. However, most RAM modules can withstand voltages over 3.5V. To find out if your RAM can withstand such high voltages, simply visit the RAM chip manufacturer’s site and look up the datasheet of the particular chip you are using




simple pictures just won't do without any detailed explanantion.
