Lately, whenever my computer reaches 50% memory usage (8/16GB), I will get all kinds of glitchieness and application crashes. I'm running a game and a web browser simultaneously. I've booted the computer with both sticks individually, and run the windows memory test, as well as memtest86+. Neither revesled any errors. It's a laptop with both an integrated and dedicated GPU. Game on dGPU, everything else on iGPU. Any ideas? Thanks!
