Question: 1 / 690

After installing two memory modules, what should you do if only one is recognized by the BIOS?

Update the BIOS software

Ensure both modules are seated properly

Ensuring that both memory modules are seated properly is crucial because improper seating is a common issue that can prevent a module from being recognized by the BIOS. Memory modules need to be firmly inserted into their slots with the notches aligned correctly to make a proper connection with the motherboard. If one module isn’t seated correctly, it might not establish contact and thus will not appear during the BIOS memory check.

Additionally, while updating the BIOS or running memory test software can be helpful troubleshooting steps, it is more logical to first check the physical installation of the memory modules. Replacing the unrecognized module should be considered as a last resort after verifying that both modules are properly seated. Therefore, checking the seating is the most immediate and practical solution to address the issue of recognition by the BIOS.
