Only four gigabytes are available for use despite having eight gigabytes of memory.
Only four gigabytes are available for use despite having eight gigabytes of memory.
The topic is clear, thanks for the update. I attempted several changes: swapped RAM, updated BIOS, refreshed Windows, installed new drivers, turned off memory limits in msconfig, enabled memory remapping (though not available in BIOS), reinstalled the PC. Before updating BIOS, the system had 3.98 GB usable, now it's 4 GB. My motherboard is ASRock N68-GS4, the graphics card is AMD Radeon R7 360, CPU is AMD FX-4320. I also added two 4 GB RAM sticks.
The issue lies in the hardware allocation. Running with just one drive can affect performance. If you boot using only one stick, does the system allocate 2GB to hardware reserved or does it completely disable it?
Yes, one of those sticks has broken. For a budget, you can purchase another 4GB stick. Aim for one that matches the previous model in speed and timing. Alternatively, if you can afford it, buy a new kit and keep the working stick as a backup.
