You're dealing with a mismatch between your motherboard and the RAM modules you're using. The ASUS Z87-C supports up to 32GB of DDR3, but your setup is limited by the BIOS and the modules you have. Since the BIOS only sees 8GB of RAM, it won't recognize the full capacity of your sticks. You’ll need to either replace the modules with compatible ones or upgrade your BIOS settings to reflect the actual RAM size. If you want a better fit, consider modules that match your motherboard's specifications or check for newer BIOS updates.

Registered sticks aren't compatible. Unbuffered ECC could be an option, but only outside ECC mode. These usually cost more than standard models, so opt for desktops if needed.

Ddr3 is now incredibly affordable, making it worth considering even though registered ecc isn't reliable on consumer boards. It's also an x1x4 configuration, which means even high-end models like x58 and x79 might struggle with x4 RAM due to board limitations. If the RAM isn't OEM and you're using a regular board, mismatched configurations can cause issues. For safety, aim for DDR3 3200 or higher—those ASUS boards seem to handle it better, supporting 3200 or more with ease.
