Is clearing the CMOS on the motherboard the same as loading default settings?

[chainers]

Hello all,

I have been having motherboard issues lately, and curious to see if removing the CMOS battery (or clearing by pressing 2 pins) would be the same as resetting the default settings in the BIOS.

My PC won't fully recognize my memory. It will see a single stick in either DIMM slots, but when both are put in it will only recognize half the memory on each stick. I am hoping that removing the battery and re-adding it in will reset to factory settings, and might fix the issue. Is this a hopeless dream, or is there some merit to what I am trying to do?

Yes a CMOS reset will restore all BIOS settings to their default configuration.


Are you 100% positive the board and RAM are compatible?

Hi

No, if cmos settings get corruped , cpu& motherboard may not power on
After clearing cmos ram you gointo bios or uefi, reset date and time
Reload the defalt settings
This can cause problems if you have RAID, or made changes away from defaults

Eg sata controller to ahci or pata or RAID
Mbr or gpt hard disk access
It helps to note important settings before clearing cmos ram

If changing cpu usually best to reset cmos afterwards

100%. I checked the board and RAM before buying, and when the issue started to arise.

The RAM posted just fine for the 3 months I have been using it, but now will not post OCed at all, and am having the memory issue I mentioned prior. Memcheck won't show all 16 gigs, and last time it did it failed the test hard.

I am hoping reseting the CMOS will help, because unfortunately MSI has the worst RMA support, pretty much telling me to take apart my PC, send them the board back and just hope the CPU doesn't get damaged while they fix it. Def will not be making a purchase with that company again.

Thank you for letting me know. I have not done any RAID settings on this, and the only changes I have made would be to enable Memory OCing (through XMP profile). Sadly I am not confident that resetting the CMOS will work, but hey it is at least worth a shot right?
