GTA 5 Memory Errors Fix - ERR_MEM Solutions 2026

Common Memory Errors in Modded GTA 5

Memory errors are the most frequent crashes in heavily modded GTA 5. They occur when the game exceeds its allocated memory pools. Below are all major error codes and their fixes for 2026.

Error Codes Reference

Fix #1: Update gameconfig.xml

This is the most important fix. A proper gameconfig sets higher limits for all memory pools.

1. Download the latest gameconfig.xml for your game version from gta5-mods.com
2. Place it in: mods/update/update.rpf/common/data/
3. Choose the version matching your mod load (light/medium/heavy)

Key pool sizes to check:

• VehiclePool — default 128, set to 300+ for addon vehicles
• PedPool — default 120, set to 250+ for addon peds
• MapDataStorePool — increase for custom maps
• StreamingPool — base streaming memory allocation

Fix #2: Install Heap Limit Adjuster

1. Download HeapAdjuster.asi from gta5-mods.com
2. Place in GTA 5 root folder (next to GTA5.exe)
3. It automatically expands the game's heap from 500MB to ~4GB

Fix #3: Install Packfile Limit Adjuster

Required if you have many addon DLC packs (vehicles, maps, peds):

1. Download PackfileLimitAdjuster.asi
2. Place in GTA 5 root folder
3. Increases the limit from 3072 to 8192 RPF entries

Prevention Tips

• Monitor RAM usage — modded GTA 5 needs 12-16GB RAM minimum
• Use compressed textures (.ytd optimization) to reduce memory footprint
• Remove unused mods — each addon reserves pool space even when not spawned
• Keep gameconfig.xml updated whenever you add significant new mods
