Hi, i'm new to these forums, as you can see, i registered a few minutes ago for the sole purpose of resolving this issue with my G.Skill RAM sticks.

I recently built my first AMD PC (i'm new to all of this) and had many problems along the way. Many were resolved but i'm still a long ways to go before this completed build becomes optimum for any demanding tasks. My problem as of right now is with the 8GB of G.Skill memory sticks, in that it is only "using" or recognizing 3.95 gigs of the 8192 MBytes that are currently installed. The thing is when i check the Bios it shows the full 8 gigs, but in the Windows Index area it shows "8.00 GB (3.95 GB usable)." Also, when i open Task Manager>Performance>Resource Monitor>Memory it tells me that 4147MB is hardware reserved. Any help would be appreciated!

My specs:

AMD FX-4130 Zambezi 3.8GHz Socket AM3+
MSI 970A-G46 AM3+ AMD 970
G.SKILL Ripjaws Series 8GB (2 x 4GB)
SAPPHIRE 100358L Radeon HD 7770 GHz Edition 1GB
Western Digital WD1002FAEX Caviar Black 1 TB
Windows 7 Home Premium SP1 64bit (OEM)

Or you could update the latest version of motherboard BIOS, and check out the thread below:
TR Forums • View topic - Hardware Reserved Memory (http://techreport.com/forums/viewtopic.php?f=36&t=74319)

Also there are a few things you can try:

#1: Go to Run and type msconfig. Once you do this a box will come up and then go to the boot tab. On advanced options on the boot you will find two options, number of processors and max memory. Select the box max memory and it should automatically put the amount of memory installed. Once you reboot it will allocate more memory to your sytem but still hold a bit back for hardware requirements.

#2: You can try Memory Remapping through the BIOS.

#3: Reinstall Windows.
