Can it be Ram Bottleneck?
Can it be Ram Bottleneck?
Hello, While playing games I notice the GPU consistently runs at 97-100% but occasionally drops to 50-70% for a brief moment. I also experience occasional low frame rates around 0.1%. Could it be related to RAM limitations? Your system specs are: CPU - Ryzen 5 4500, GPU - RX 480 with 4GB RAM (recently added an 8GB stick), motherboard - MSI A320M-A Pro, power supply - Super Flower 500W Eco King 80+ Bronze. SSDs and HDDs are used for different games, but I haven't noticed any performance impact. Anyone have advice?
It's likely the poor power delivery on your motherboard is restricting performance or you're facing a CPU bottleneck. Verify your CPU usage in-game by installing MSI Afterburner via Rivatuner and note the percentage while maintaining 50% GPU utilization and your CPU's power draw.
Checking the CPU power consumption. Usage between 10-70% varies with the game.
You're using a single RAM DIMM, which means you're operating in single-channel mode. I recommend testing with two DIMMs first, especially when RAM is running in dual-channel. For Ryzen processors, this setup can impact performance. Your CPU should maintain 100% for an RX 480 in games that match your expectations. Which titles are you experiencing this issue with?
Other titles I haven't played are uncertain since I haven't tried them.
Core clocks perform adequately with the CPU in the attached image, though power consumption may increase slightly at 80% load. Updated March 15, 2023 by filpo
