Hey everyone! I recently upgraded my friend's GPU from an RX 480 to an RX 9060 XT. I installed the latest optional driver (25.6.1) that worked well for my setup, but now his games are suffering from terrible lag spikes, especially noticeable in the 1% lows across all titles. I had a similar issue previously, which I fixed by only using the 2x16GB RAM instead of mixing them with 2x8GB. He has 48GB of RAM (2x8GB and 2x16GB), so I'm concerned that's the issue again. Also, I noticed that the Wi-Fi module was turned on after using DDU to clean the drivers. Do you think the problem is due to the drivers, or could it really be the memory configuration since his old GPU was fine with games like CS2 and L4D2? Here's his build:
- R 7 5700X
- RX 9060 XT 8GB
- B550M Pro
- 48GB RAM (2x8GB & 2x16GB)
- 650W PSU
- Playing on a 1600x900 monitor (hasn't upgraded this yet).

You might want to ensure that the previous GPU drivers were completely uninstalled. Using the AMD Cleanup Utility could help clear everything out before reinstalling the latest drivers. Here's the link for reference: https://www.amd.com/en/resources/support-articles/faqs/GPU-601.html
I'd love updates on this! I recently upgraded to a 9070 XT from a 1660S and I'm also seeing some frame stability issues. It'd be great to know if and how you solve this.
I think the RAM mix could be a big issue. It's not recommended to mix different RAM kits, even if they look the same. You should definitely remove the 2x8GB sticks and see how that goes.
I wouldn't say mixing RAM is the worst thing ever, but it can lead to problems, especially with performance.
Don't forget to tweak some BIOS settings! Disabling CSM and enabling Re-Bar could really help. Also, make sure those games are running off an SSD or NVMe drive instead of an HDD.
Thanks for the tip! I actually disabled CSM already but will check the storage next.
At that resolution (1600x900), it's likely that your CPU is bottlenecking the performance since the RX 9060 XT can push those frames easily. Keep an eye on your CPU and GPU usage while gaming to check.
I agree, that's the best first step. It's crazy how sensitive RAM can be with different setups!
