Should I switch memory modes for Asgard Thor DDR5 6400?
Right in the middle of a sandstorm fight, my FPS would suddenly tank from 80 down to 40, which is an absolute rollercoaster of frustration. It turns out the default profiles for the Asgard Thor DDR5 6400 have some compatibility quirks with certain boards, causing the memory controller to jump wildly between 5600MHz - 6400MHz. I tried lowering the in-game settings, but while the FPS went up, the game looked terrible, and that was a compromise I wasn't willing to make. I went into the BIOS, locked the frequency at a steady 6000MHz, and bumped the voltage from 1.35V to 1.38V for absolute stability. Monitoring with RTSS, the frame times tightened from 18-38ms to a smooth 12-16ms, and the drops disappeared. Interestingly, locking it at 6000MHz actually cost me about 2 FPS at first, until I fine-tuned the secondary timings to get the performance back. Memory temps stayed stable between 52-58℃. I verified the frequency lock in the driver panel, and temps held at 52-58℃.
