Why does my Asgard Thor DDR5 6400 keep stuttering in SM2 PC?
When zipping through Manhattan, I noticed these micro-freezes that totally kill the momentum. It was a nightmare. My Asgard Thor DDR5 6400 XMP profile was hitting random latency spikes of 18-25ns when loading massive city assets, which basically choked the CPU instruction queue. I tried switching the Windows power plan to Ultimate Performance, but that just pushed my core temps to 82℃ without fixing a single stutter—totally useless. I eventually dove into the BIOS Advanced settings and loosened the primary timings from 32-39-39-76 to 34-40-40-80, while bumping the DRAM voltage from 1.35V to 1.38V. Using HWiNFO, I saw the frame time variance shrink from a wild 22-45ms down to a rock-steady 14-18ms. To be honest, I black-screened twice at first because the timings were too tight, but it stabilized after I dialed back the tRAS. Temps stayed around 52-58℃. Ran a full AIDA64 stress test and the latency is finally flat. It's a bit of a hassle to manually tune, but it's the only way.
