How to handle out-of-memory errors in Civ 7 on DDR3 platforms?
Once your civilization grows to thousands of units, 8GB of RAM is just not enough. The excitement of expanding my empire was instantly killed by constant freezing. My HyperX sticks were pegged at 7.4GB - 7.8GB, forcing the system to rely on painfully slow disk caching. I tried closing every background app, but I only clawed back about 200MB—totally useless. I went into system settings and forced the virtual memory to a fixed 32GB and locked the frequency at 1866MHz in the BIOS. At first, this actually caused some weird stuttering, but after I disabled the Windows Search Indexing service, turn transitions sped up by about 40%. The memory chips were running at 45℃ - 51℃, and I could hear the old capacitors on the board making a faint whining noise. Checking the commit charge curve in Resource Monitor showed the pressure had finally shifted. RAM temps stayed stable at 45℃ - 51℃, though the load times are still sluggish compared to DDR4.
