Microstuttering in the entire PC?
Microstuttering in the entire PC?
Capacitors on MoBo deteriorate over time, which also affects performance. Identifying the problem often requires a trial-and-error approach by swapping parts. From a software standpoint, you've likely addressed most issues with a clean OS installation. Replacing the DP cable eliminates display cable concerns. If your GPU is being reseated, try it with a different one—known to work—and this helps rule out GPU-related problems. Apply the same principle to other components: CPU, MoBo, and RAM. For RAM, verify there are no errors by running memtest86.

A full pass (15 tests) is the minimum; two passes are better, and four are acceptable. It may take time, so running it overnight is advisable. Each 8GB RAM test takes about an hour per full pass, totaling around 4 hours for four passes. Two 8GB units take roughly 2.5 hours per pass, adding up to about 10 hours for four passes. Four 16GB units require around 5 hours per pass, totaling approximately 20 hours for four passes.
If no errors appear, your RAM appears intact. You mentioned having a second MoBo; testing it could reveal improvements, though its limited VRM phases are a concern. Determining the exact cause of stutters is challenging due to the PC's diverse components and varying build quality.
