I currently have 8 GB of ram installed in my system. But it seems like that only 3.93 GB of it is usable.

I tried solving this issue myself using common ways from the tutorials i found on YouTube. It doesn't really work for me after several attempts. It might be me making a mistake or the ways just doesn't work at all!

On my task manager, in the performance tab and in the memory section, the graph on the right hand side shows 8 GB on top of it, which i assume my system detects 8 GB of ram installed. In the resource monitor, it also detects 8192 MB of ram installed.

PS.
My ram has xmp profile enabled @ 2666 mhz automatically. The actual speed of the ram is also 2666 mhz. However, in the task manager, my speed is @ 1067 mhz

Anyone, please help me with this issue ASAP! REALLY APPRECIATE IT!!

Ok, so, starting at the CPU and going from left to right, with the DIMM slot closest to the CPU being 1 and the one near the edge of the board being slot 4, which slots are your DIMMs (Memory modules) currently installed in?
 
Did you recently add more ram? Did you go from 4 to 8 GB?

If so do a reset of the BIOS, copy setting if you must but a reset after adding more ram to the motherboard is a common overlooked issue when not reading the full amount of ram.

i didnt have any ram upgrades. It was 8 GB initially. In my resource monitor, 8192 mb of ram is installed, however from the task manager, i only see this : (amount of ram currerently in use / 3.9 GB).

In my system information (control panel), it says : Installed memory (RAM) : 8.00 GB (3.93 GB usable)

PLEASE HELP ME :((((((

Move the DIMMs to slots 2 and 4. Then do a hard reset of the BIOS. Then see if you are showing full normal capacity.


BIOS Hard Reset procedure

Power off the unit, switch the PSU off and unplug the PSU cord from either the wall or the power supply.

Remove the motherboard CMOS battery for five minutes. In some cases it may be necessary to remove the graphics card to access the CMOS battery.

During that five minutes, press the power button on the case for 30 seconds. After the five minutes is up, reinstall the CMOS battery making sure to insert it with the correct side up just as it came out.

If you had to remove the graphics card you can now reinstall it, but remember to reconnect your power cables if there were any attached to it as well as your display cable.

Now, plug the power supply cable back in, switch the PSU back on and power up the system. It should display the POST screen and the options to enter CMOS/BIOS setup. Enter the bios setup program and reconfigure the boot settings for either the Windows boot manager or for legacy systems, the drive your OS is installed on if necessary.

Save settings and exit. If the system will POST and boot then you can move forward from there including going back into the bios and configuring any other custom settings you may need to configure such as Memory XMP profile settings, custom fan profile settings or other specific settings you may have previously had configured that were wiped out by resetting the CMOS.

In some cases it may be necessary when you go into the BIOS after a reset, to load the Optimal default or Default values and then save settings, to actually get the hardware tables to reset in the boot manager.

It is probably also worth mentioning that for anything that might require an attempt to DO a hard reset in the first place, it is a GOOD IDEA to try a different type of display as many systems will not work properly for some reason with displayport configurations. It is worth trying HDMI if you are having no display or lack of visual ability to enter the BIOS, or no signal messages.
