1.5vv

Hi.
It was always my understanding that, unless you were overclocking, you should run memory at stock speed.

Auto detect features are rarely perfect. I have a 1.8v module that loves to run at 1.9v even though the MB detects the default correctly. As soon as I manually set the voltage there's no problem. It passes memtest, prime95, and linpack at the right voltage so it's not like the MB is compensating.

I would double check your memory to make sure that 1.5v is the correct voltage and then set it to defaults if that's what you want to run at.
 
If it is indeed the 1.5v version of the memory then you should be able to set the voltage to 1.5v in the BIOS. You can run memtest to check whether it works or not. Within your operating system environment you can run something like Prime95 and choose one of the blend tests to verify stability.

I've had issues with a couple Gigabyte boards that I used in builds not recognizing the memory speed/timings correctly when set to "Auto", but after figuring out how to set everything manually to the rated specifications they worked just fine. It would seem that sometimes motherboards do not properly detect all of the memory settings properly. I would imagine it has to do with the sheer number of memory manufacturers and the massive amount of different memory models that they sell...
 
I know that my Asus Z68 board defaults the ram to 1.6v to ensure that if you are using ram that requires 1.6 volts it will POST. You just have to adjust it down to 1.5 volts in the BIOS, or if your board supports this, have the BIOS load the XMP profile from the RAM which will set the timings to 9-9-9-24 and the voltage to 1.50 volts.
 
Could also be that the memory profile (XMP) is somehow wrong. I would just manually set the memory settings to what you want if it is bugging you.
 
i just having a concern about the board is this normal for bios to detect higher voltage...??

From what mrcaffeinex and Ghiedo27 have said, the auto-detect features rarely work perfectly.

Have you manually set the voltage to 1.5 and the timings to 9-9-9-24 ? After that, if you feel inclined, run memtest, prime95, or Intel Linpack.

If you experience stability issues THEN it would be time to question your motherboard or memory.
