Clock speed drops to 0.5 under heavy usage
Clock speed drops to 0.5 under heavy usage
I recently purchased a 5900x motherboard, fresh from the box, and installed it into my PC. It runs a 4060ti with 16GB DDR4 RAM, a B450M-A PRO MAX II motherboard, and a 550W power supply. From what I’ve read, everything should function properly together. The system operates smoothly until gaming sessions start—especially titles like Marvel Rivals become extremely difficult to play. Frequently, the game stalls after just a couple of minutes, dropping to around 1 FPS for ten seconds before the clock speed rebounds to 4.2–4.5 GHz and then crashes back down to 0.5 GHz. This pattern repeats across many games, including Kingdome Come, Spiderman, and GTA V. I also ran Cinebench under heavy load; it performed similarly after about thirty seconds, returning to 4.5GHz afterward. My suspicion is that insufficient RAM might be the issue. While I’m comfortable with basic PC tasks, overclocking and advanced configurations are beyond my expertise. If anyone has insights or solutions, I’d really appreciate your help. I’ve spent a long time trying to fix this and feeling overwhelmed.
Please note: The temperatures stayed within normal limits (under 75°C) during heavy usage. The photo below shows the RAM stress test results, and here’s the link to the video for reference—though it’s quite large to upload: https://streamable.com/kv6535.

The mainboard is the central component. The 5900X is the most energy-intensive AM4 processor. Have you updated the latest BIOS?
A great Strix B550 would handle the 5900X nicely, particularly when you plan to adjust it later.
