The Secrets of PC Memory: Part 3
 

Generally, raising DRAM voltage allows for faster memory speed, “ but that also depends on the architecture of the chip too” explains Brett Williams, Senior Marketing Manager in Computing at Micron Technology.

“ If the voltage is designed to be regulated, then increasing the external voltage might not do anything for the chip because you have got a regulator on the chip that is keeping the core at a specific voltage. If the chip is unregulated, when you increase the external voltage, it goes right into the core and increasing the core voltage allows the part to operate faster.”

As enthusiasts, we often enjoy the power of having various DRAM tweaking configurations exposed in the motherboard BIOS. While they may be useful, average users at home do not have an intimate understanding of most functions in order to establish a basis to make effective performance improvements.
