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

Kingston HyperX Fury 4GB (2x)

Windows 8.1 SL OEM 64 Bit

This is a problem I've seen a time or two. Let's start at the top.
Memory remap issue: Do you have the latest version of your motherboard's BIOS? If not, update it and see if the issue resolves itself.

Download CPU-Z from www.cpuid.com and see if your memory is recognized.

A problem like this can be any of a few things, so we'll keep throwing suggestions out there. One of us will guess it eventually. Before we get physical (popping DIMMs and checking for bum slots), we'll keep focusing on software configuration.
Now that the BIOS is up to date, check the memory remap option in the BIOS. Toggle it to the opposite of whatever setting it's on, restart and see if it brings you luck.

Your BIOS may not have the option at all. Some of the AMI BIOS boards, like your ASRock, keep it as an adjustable options, while others do not.
You can try adjusting your DRAM frequency in this BIOS from Auto to it's rated speed, which has sometimes worked.
At this point, the fastest solution might be to swam your RAM to the opposite slots on your motherboard.

alright, i will put the sticks on the first and third slot now.
UPDATE:
Still no luck, the sticks are on the first and third slot and i've also manually changed the DRAM frequency on the BIOS but it still uses 4gb out of 8
also i've just noticed that the debug monitor on the mobo showed "AA" when i updated the BIOS i think this is normal

ive lowered the frequency and yes i have also looked at the compatibility for memory, my GPU isnt even compatible (i think thats the reason the driver always crashes) but its still 4gb useable, any last resort?
To the guy above me, Ive already checked and it was unticked in the first place and I HAVE WINDOWS 8.1

Still trying to find a solution for that "hardware reserved" since imo that is your problem.
No setting in the bios that does anything,like under "Advanced" -> "Cpu Configuration"-> "Secure Virtual Machine" -> @ disabled?
Just to try out.
Was wondering about settings in the register,but am not sure where to look,found this,
open Regedit->
Hkey local machine->CurrentControlSet->Control->SystemResources->ReservedResources ...What is the value there for you?
Btw have you tried with the ram @ 1333mhz for instance? With the settings (voltage/tmings) accordingly like displayed in cpu-z.From what i can tell are you now at ~1866mhz.

Go into BIOS and try raising the DRAM voltage to + 0.05 (1.55 - maybe even to 1.6) and the CPU/NB voltage to 1.2
Problem may be incompatibility here as the Fury's are PnP where most all DRAM uses XMP to put their profiles in the SPD of the DRAM and the chipset isn't compatible to PnP (according to Kingston)

Run Memtest86 from http://www.memtest86.com
Read the instructions carefully. It takes several hours to run. Any single error in the test and REJECT that RAM, send it back for replacement.

Alright, I am back.
I have replaced my PSU and I asked the vendor to replace my sticks because of the problem (this was my last resort at this point) and they worked! The PC used all 8gb of ram! I guess the sticks were broken or something...
Thanks for all the help tho, guys!
Solution:
If any of the answers above doesn't work, Go to the vendor, where you bought your ram (bring with you your receipt and the ram sticks) and tell them the problem and they will most probably replace the sticks with new (but similar) sticks.
