I own a ASUS PN52 Mini PC (barebone version). I contacted ASUS support because system uses to hang. They told me the 3200 MT/s memory module i installed was not in the QVL (Qualified Vendor List), so i should replace it by another one within the list. I found out the QVL is outdated and there is no 3200 MT/s module option available in the market (!). So they are trying to convince me to downgrade to a slower memory module. That's not serious.
