Question

motherboards

There was a RAM

Became

I wanted a larger number of RAM in the PC. 16 GB works (2 those or 2 those) OR (one that and one that)
And immediately 4 are not. What's the matter? Stupidly the bios does not even start.


I tried to change while CL is working - it does not help.

Answer 1

Answer 2

Disable XMP profile
