Poor performance following GPU upgrade
Poor performance following GPU upgrade
I recently upgraded from an RTX 2060 to an RX 9060 XT with 16GB OC and noticed a drop in performance compared to before. The frame rate remains similar, but there are occasional drops and lower FPS. I mostly play Fortnite, BF6, Warhammer, and LoL, and the issue seems consistent across all games. My current setup includes an Intel i5 12400, RX 9060 XT 16GB, 32GB DDR4 RAM at 2400MHz, two 16GB SSDs, a HyperX 2TB storage drive, a 1TB M.2 SSD, and a Gigabyte B760 DS3DH motherboard. I've used DDU and adjusted settings without much success. It might be a RAM problem or the PSU isn't powerful enough.
You have three RAM modules: one 16GB stick and two 8GB sticks. Don't mix them. Use the 16GB stick and place the 8GB sticks in the right slots—often positions like 1 and 3 or 2 and 4 work. Make sure they support faster speeds through XMP settings. The PSU is sufficient, and the CPU handles the 9060XT well.
I think this setup might be contributing to the issue. Remove the 16GB stick, ensure your leftover RAM uses dual-channel by placing modules in the second and fourth slots. Then check the BIOS settings to confirm it supports 3000Mhz CL16. Finally, run a benchmark test to verify any performance gains.
It may be that your CPU is bottlenecking in the games you play. Unless the RAM is damaged or defective, I don't think you would see much performance hit from mismatched sticks.
Set up Intel PresentMon, turn on GPU and CPU busy tracking, and test a few applications. Observe if CPU busy exceeds GPU busy—this suggests CPU limits performance. Confirm XMP is active in BIOS settings. Ensure your RAM is installed in channel A (1x16) and channel B (2x8), which should enable dual-channel operation (verify with CPU-Z). If the system fails to start with XMP enabled, consider using only the 2x8 configuration.
I'm not sure if it was the two different types of RAM that caused the problem. It seems fixing it by enabling XMP helped, but I did both changes. I took out the 16GB stick and set XMP to run at 3200MHz, even though the RAM supports 3600MHz. It still doesn't work at that speed, but now I'm getting stable and good frame rates. Thanks for your assistance!
