How to fix memory overflows in UE5 on ASRock A320M-HDV?
The detail in Nanite is absolutely mind-blowing, but the software crashes were just as frequent. The logs showed the memory controller on my ASRock A320M-HDV R4.0 was hitting serious addressing errors when handling geometry data over 16GB. I tried the 'Auto OC' in BIOS first, which was a huge mistake—it sent me into an infinite boot loop. Lesson learned: don't push old platforms too hard. I manually loosened the timings from 16-18-18-36 to 18-20-20-40 and bumped the virtual memory to 32GB. After four passes of MemTest86, the error count dropped from 12 to zero. I lost maybe 3 FPS because of the looser timings, but at least I can actually finish the demo now. RAM temps are 45-52℃ and the CPU is stable at 62-68℃. I also switched the rendering from Lumen to simple lighting in the engine settings to keep things fluid. The input response is finally snappy and feels natural under my fingers.
