I am building a gaming pc I had 1 stick of 8g ram which works I tried to upstage to 2 sticks of 8g (completely new ram different from the first stick I had) and it didn't work the pc power light would come on but nothing on the screen so I put in the old stick then bought the same exact stick to double it to 16g and it still isn't working
Hi Ethan
Mixing different RAM kits as you describe is not a good idea and can cause issues.
It is during the manufacturing process where slight discrepancies regarding latency and Timings can differ and that's why the manufacturers bin modules into kits to ensure compliance.
Sometimes they do work with tweaking Primary Timings and voltage in Bios but no guarantee.
If the kits you have work...
