Ram of 1333 mhz with 1600 mhz ?

That's ok, thanks. Scotch seems to help. :)

Scroll down on that last page you posted. It will show all the voltages for CPU, chipset, etc. Look for one called DRAM. What does that one say.

I don't know about CPU-Z other that it just reads the info off the module. It's probably not setup (programmed) for variable voltages. The same for Speccy but it has never has been very accurate from my experience. The flexible voltage modules must be relatively new to cut down on production costs vs. separate voltage modules. As I mentioned, it's the first one I've seen. What's important is the compatible speed. The BIOS will set both modules to the slowest compatible speed.

Open an elevated Command prompt (Run as Administrator). Type the command winsat mem then post an image of the results. This will test the speed of your memory and show it as MB/second.

16GB/s is about average for DDR3. Even better than many. I wouldn't worry about the voltage. I think you're good to go.

but why Cup-Z and Speccy didn't show 1.50v with 1.35v ? they only show 1.35v


I looked up by the Module Part Number and I found this

Because I think CPU-z only shows the advertised voltages and not the actual used.

Look at the bios for actual.
