Fixing the 7800X3D memory latency spikes in Manor Lords?
The simulation load in this game is just insane. My CPU basically decided to go on strike, which was just great. Even with the 3D V-Cache, the Ryzen 7 7800X3D was seeing memory latency swing wildly between 75-110 ns when processing thousands of entities, which triggered the game's memory protection and crashed it. I tried lowering the population cap, but that just made the game boring without stopping the crashes—a complete waste of my time. I headed into the BIOS, locked the FCLK frequency at 2000 MHz, and tightened the main memory timings from 36-36-36-76 down to 32-38-38-72. After 4 hours of TM5 stress testing, there wasn't a single error, and latency stabilized at 64-68 ns. I actually hit some WHEA errors early on because I pushed the FCLK too high, but dropping it by 100 MHz fixed everything. CPU is at 65-75℃, and RAM is between 48-54℃. Exported the latency curves to confirm the fix.
