    Is there a tool that will tell you what voltage the laptop memory is operating at?

    Sorry if this question has already been answered, but after hours of searching could not find an answer. I recently upgraded the memory on my Samsung laptop NP-355v (A10 4600m processor) from DDR3 (1.5v) to DDR3L (1.35v). What I would like to know is if the BIOS will automatically read the memory SPD and adjust the voltage to 1.35v? I know the chipset supports 1.35v, but not sure if the Samsung BIOS also supports it. Is there a tool that can tell you the operating voltage without resorting to a voltmeter? HWINFO, CPUz, just tell you the supported voltage on the SPD but do not tell you actual voltage.The BIOS options are very primitive so unfortunately there is no info there.

    Thanks for any help

    Unfortunately, CPU-z just reads the SPD info from the memory stick. It doesn't tell you what the actual voltage that the chip is supplying.

    HWINFO does give you voltage readings. Either checkmark "sensors-only" when you start the program or click on the "sensors" button on the top panel of the hardware info box (2ndary box that pops up behind the "system summary" box).

    Hope this helps.

    Tried HWINFO, it does give you voltage readings (from the ATI PM2 chip) but none for memory for the AMD trinity
