I recently bought an unlabeled set of ADATA XPG RAM and I wanted to find out any information about it. So installed the ram, booted into windows, and ran these commands in command prompt.

> wmic MEMORYCHIP get >data.txt

>start data.txt

The text file gave me this information

ConfiguredClockSpeed: 1333
PartNumber: DDR3 1866
Speed:1333

Why is the Part number different and which one is correct?

CPU-z didn't give me too much information on the RAM but I checked out my motherboard specs online and it only supports 1333/1600 RAM. Now I'm not sure why it's not running at 1600 MHz but I'm selling the motherboard anyways so I'm fine with it.
