Is this normal? if not then how do I use ALL of the memory?
It detects that I have 8gb of ram but it only uses 4gb of it
I saw that 4gb was in hardware reserve and i dunno how to allocate more memory for use

I have Windows 8.1 SL OEM

AMD FX-8350 8-Core @ 4GHz | Cooler Master Seidon 120v Liquid Cooling System | AMD Radeon R7 250 2gb DDR3 with Boost | ASRock 990FX Extreme4 | Kingston HyperX Fury 4gb (2x) | ThermaTake 700w LitePower| WD Caviar Green 2TB HDD | Corsair Carbide 300R Windowed


1. BIOS is updated
2. I can only change the DRAM Frequency in the BIOS, I currently set it to 1600 in hopes of fixing it
3. Msconfig > Boot > Advanced > Maximum memory unticked
4. I have also put both sticks in slot 1 & 3 but no luck
5. Kingston HyperX Fury is not on my mobo's compatibility list
6. Regedit-> Hkey local machine->CurrentControlSet->Control->SystemResources->ReservedResources -> No Value set
7. I tried to boot my pc using each sticks themselves, still no luck but:

8. There are no programs that are hogging the ram yet
9. I have contacted the Kingston representative over at tomshardware.com
10. for more details: 8GB of ram installed but i can only use 4GB of it? - RAM - Memory

Will be adding more information when asked!

Thanks in advance! :)

Hello there photoshoplol,you think you could check in BIOS,if you have a "memory remap feature" or something similar,to make your memory usable?

Go to Run...

  • Type in "MSCONFIG" (without quotes)
  • Click on the Boot tab,
  • Click Advanced Options
  • Make sure the Maximum Memory: box is un-checked. (you might also make sure the Number of processors box is also un-checked as well).

If the boxes were checked, this should solve your issue. If the boxes were not checked, we need to look elsewhere.

Please let us know.

Download speccy from Speccy - System Information - Free Download and post the URL that comes up after you run the program. With Windows 8.x.x x64bit, it should be using all 8gb. I am gambling also that it is a bios issue. Others have had RAM issues with this same Motherboard. See AsRock 990FX Extreme4 won't run 32GB DDR3-1866 at more than 1600Mhz [Solved] - DDR3 - Memory

Run Memtest to check all RAM. If you have an extra USB pocket stick. Install Clonezilla on it. It comes with Memtest as a part of the software. Clonezilla live It can be ran as a USB or DVD install.

Looking at the spec's on this motherboard. Depending on what CPU you are using. Limits the RAM installed, that can be used. ASRock > 990FX Extreme4
