I just saw a hand full saying that myself...
Regardless, I would recommend always manually setting the RAM voltage, timings and speed in the BIOS.
It is very simple to do (takes about a minute) and it will insure that you have no issues with your build.
If you have concerns about modifying anything in the BIOS, perhaps you should look into a different set of RAM.This OCZ Gold
set will save you $10 and there are no reports of it using a voltage higher than 1.65v at stock.
