Just today I noted that one of my RAM sticks was off-colored. I checked my task manager only to find out that I had half the memory that I normally would have running at half the minimum speed for DDR4. I tried using sysdm.cpl and msconfig, as well as tweaking things in my BIOS, all to no effect. This issue happened to me about a year and a half ago, and I resolved it but soon forgot how to. The issue is stick specific. Swapping their locations results in the same stick not being detected. However, I'm almost 100% sure the stick is not dead, as it is still appearing to be powered on. Any help will be appreciated. Thanks!
