Memory Voltages(Running memory at lower voltages) Tags: Memory RAM Last response: July 18, 2012 1:46 PM in Memory Share kroeger July 12, 2012 10:25:11 PM I just got a new Sandy Bridge based system a few weeks ago. i7 3930k/Dx79TO The ram that I had purchased is the following: http://www.corsair.com/en/cmx4gx3m1a1600c9.html After completing the build I found that running the ram modules at the factory set XMP profile 1600MHz@1.65v might harm my Cpu. So I dialed down the voltage to 1.5v using the Intel supplied extreme tuning utility. The modules now run at 1600MHz@1.5v The system is stable so far.I haven't had any problems using the Stress tests built into the Intel Extreme tuning utility. My question is that can I continue to use the system at this voltage without any harm to either Cpu or Ram or any other system components. Also can you tell me if the settings that are being used are optimal as per the 1.5v being supplied. The profile being used(similar to the XMP profile but at 1.5v)- http://i1247.photobucket.com/albums/gg632/jarpickle/Mem... Factory set XMP- http://i1247.photobucket.com/albums/gg632/jarpickle/Def...
