I've been experiencing random freezes and crashes while gaming, often related to "dx12" or "gpu_hung" errors, about once a day. There were also weird memory read/write errors when shutting down my PC. I was using a 5070ti with a Ryzen 5 7600 CPU. Despite the crashes indicating GPU issues, the graphics card performed well when it wasn't crashing. Games like Ready or Not would crash when loading multiplayer, Cyberpunk would crash unexpectedly, and Battlefield 2042 would crash right at the main menu. Even Witcher 3 caused a complete system freeze, necessitating a hard reboot, and Red Dead 2 showed an "out of memory" crash, which seemed ridiculous with 64GB of RAM and 16GB of VRAM at 1440p. The Ryzen 5 7600 seemed to underperform, only giving me 50-60fps in RDR2 when it should be much higher. However, for GPU-heavy games like Cyberpunk, I would see 90fps initially, but performance dropped the longer I played. Temps were always fine, but eventually, I faced POST issues necessitating a CMOS reset, especially after trying any EXPO memory profiles. The read/write memory errors happened leading up to my CPU replacement, which prompted me to buy a 7800x3d on sale. Since upgrading, my fps in every game has basically doubled—Tarkov from 60-70fps to 140fps, RDR2 from 55fps to 135fps, Cyberpunk from 90fps to 120fps—and there haven't been any crashes or errors at all. I have an ASRock A620MC motherboard with 64GB DDR5 6000 EXPO RAM. Was my old CPU failing, potentially causing the GPU and memory errors? I'm concerned that the previous board may have sent too much voltage to the CPU's memory controller, damaging my old CPU, as the crashes persisted even without EXPO.

Just a heads up, I’m not an expert or anything, but I had some similar issues on a new build with an Intel CPU. I faced various crashes too when running my RAM at XMP speeds. In my case, reseating the RAM fixed the problem. If AMD memory controllers aren't as robust, it’s possible your old CPU couldn’t handle the EXPO settings, which might’ve led to those errors. You might have gotten a chip with a hidden defect, especially if it failed relatively fast.
Memory issues can really be tricky! It sounds like your 7600 might have had problems with its memory controller or channels, which could definitely lead to all those crashes you experienced. Sometimes a failing memory controller can manifest as errors in other components, like your GPU.
Yeah, unstable RAM overclocking can definitely cause those kinds of issues. Your new CPU might just have a more stable memory controller compared to the old one, allowing things to run smoother now. Still, it’s odd that the old setup crashed with EXPO enabled even on components that were said to be compatible.
By the way, do you have 2x32GB or 4x16GB for your RAM?
I’ve got 2x32GB G.Skill RAM.

Right? I checked compatibility too, and it should’ve worked. I also tried different RAM kits and configurations with no luck. Never touched the CPU overclocking or timing settings myself, so that was frustrating.
