Is my RAM speed 2666 or 3200 MHz?
From my research 3200MHz runs at 1.2V, as per my voltage below, and 2667Mhz runs at a higher voltage of about 1.35V. I looked up the datasheet of the mikron 8ATF1G64HZ-2G6J1 chip, and it says 3200Mhz. However below it says the speed is 2667Mhz. My research also says that windows often miscorrectly reports the speed. So I am no tsure. I have a Dell Precision 7530 Laptop that I am trying to upgrade the RAM, and would like to match the speed (before I upgrade the OS to Linux, which may use the full speed). Is windows reporting 2667Mhz because its configured to that?
When I run wmic memorychip get from the windows cmd I get the following:

There seems to be conflicting clues (voltage vs clock speed) of what the RAM hardware speed actually is. So do I buy 2667Mhz or 3200Mhz RAM?
Also strangely enough the 3200MHz memory is cheaper, should I just buy the 3200Mhz and stick it in, and it will run slower at 2666Mhz?
