Just built a new PC and I'm having a problem with my operating system (win7 x64) only using half my memory. I have 32gb (4x8gb Kingston HyperX) installed in my Asus Maximus VI Hero motherboard, but when I run msinfo32 this is what I get:

Installed Physical Memory (RAM) 32GB
Total Physical Memory 16GB

In msconfig>Boot>Advanced Maximum Memory setting is unticked

CPU is i7 4770k

If you're using Windows 7 Home Premium 64bit then that's your issue, it's limited to 16GB

Windows 7 Ultimate, Windows 7 Enterprise and Windows 7 professional (The 64bit versions) allow anything above 16GB

Gah you're right guys, I never came across any info on this when I was researching my memory! I suppose the cheapest way for me to get Pro is the Anytime Upgrade feature. Do any of you know whether the upgrade is permanent: ie - if I were to re-install windows at a later point in time (on the same PC), would the upgrade still be usable or would I have to buy a new upgrade?
