Always needs to reinitialize CMOS before starting after installing additional RAM modules
Always needs to reinitialize CMOS before starting after installing additional RAM modules
I just upgraded two RAM sticks, which filled four slots. Now the monitor stays black during startup, forcing a CMOS reset each time. Need a permanent fix?
verified if your BIOS is current; updating it could resolve this strange issue. If no update exists, consider resetting BIOS settings to defaults before fully erasing everything. Another aspect to review is whether your RAM supports DDR5—after any changes, the system may require memory training, causing a brief pause before startup. This doesn’t seem applicable here since you haven’t specified your PC’s specifications. Based on what you mentioned, it appears you’re likely using DDR4.
When using mixed kits, pairing DIMMs often improves performance. The IMC maintains identical capacity per dual channel, avoiding the need to switch between different module capacities. For example, combining a 16GB stick with an 8GB stick in dual channel works well. Most users place the DIMMs in the sets they receive.
Even when purchasing identical RAM modules, compatibility isn't guaranteed. I encountered this issue once—same brand, speed, and type didn’t always match. You usually need to buy multiple sticks together (such as a pack of four) or two packs of two at once. Keep in mind that if your motherboard only supports dual channels and not quad, enabling XMP mode with four sticks might cause instability, leading to crashes or error messages. For gaming or performance-intensive tasks, ensure your system has a quad channel motherboard to unlock full potential. If you mainly use it for editing or similar tasks, XMP may be unnecessary and won’t hurt.
