32gb Installed (16gb Usable??)

[SyrumX]

So let's jump into my specs:
-ASUS Sabertooth Z77
-Intel Core i7-3770k
-Corsair Dominator GT (4x8) :: http://www.newegg.com/Product/Product.aspx?Item=N82E16820233271&Tpk=corsair%20dominator%20gt%2032gb
-Geforce GTX 670 4gb sc
-Thermaltake TR2 600w
-Windows 7 Home 64bit

I recently upgraded my ram, and the ram i chose was from the QVL on ASUS site for this motherboard. So what i dont understand is, why wont it use all 32gb of ram?

Are you saying that windows reports seeing only 16gb of ram? Not the full 32gb.
That means either the motherboard is faulty or you have some bad ram.

 

[SyrumX]

No. it does report all 32gb of ram. But then is says 16gb usable. Even though this ram is qualified by my mobo.

Installed memory (RAM): 32.0 GB(16.0 GB usable)

Are you using Win 7 home Premium? That version only supports up to 16GB physical ram, whereas 7 Pro and Ultimate support up to 192GB of ram.

Oh.. well that answers everything. Yes its Home Premium. Is there any reason for that though? Why is home limited to 16gb?

Because microsoft decided that 16gb should be enough for any home user and anything past that should require a "business" OS like professional and above.

Does Win 8 support 32GB?

Does Win 8 support 32GB?

"32-bit versions of Windows 8 support up to 4 GB of RAM. The 64-bit version of Windows 8 Pro supports up to 512 GB while the 64-bit version of Windows 8 (standard) supports up to 128 GB."

Taken from: http://pcsupport.about.com/od/windows-8/a/windows-8.htm

So yeah, you could use 32 gigs just fine on 8
