Hello! Thank you for checking out my article! The central issue here is whether the system should automatically select the RAM with the slowest CAS latency. In my BIOS settings, it’s set to 36-36-36-76, and CPU-Z confirms that. Does this align with expectations? I was expecting a higher number to mean slower performance, but I’m not sure if that’s the case. If this is incorrect, could it be contributing to the problems I’m experiencing? I’ve enabled XMP profiles, but I still feel uncertain about timing settings.

More details: I recently assembled a new PC and initially everything worked well. Then, after adding some RAM with RGB lighting, I began encountering various malfunctions—blue screens, freezing, crashes in games, and occasional graphical glitches. Despite running stress tests for hours, the system remained stable most of the time. However, occasional BSODs appeared, sometimes with error codes like "attempted to write to read only memory" or red graphical errors on my second monitor.

I recently reinstalled Windows 10 from a USB drive, trying to clear any software-related problems. It worked for a while, but yesterday I experienced crashes again without any noticeable changes afterward. I ran SFC and CHKDSK, which resolved some files, and a Windows memory test showed hardware errors once. After reseating the RAM and running another test, everything seemed fine—though I’m still unsure if the fix was permanent.

I’m currently on the latest BIOS for my motherboard, as newer versions have caused issues in the past. The BIOS is up to date, and I’m using the newest drivers for the GPU and other components. My specs include an Intel 13900k with 64GB DDR5 RAM (the pairs linked are shown). I’m also using a MOBO ROG STRIX Z690-Gaming WIFI system with cooling fans.

I’m hoping someone can help me identify what’s causing these strange crashes before I have to visit a repair shop. If you have any insights or tests you recommend, it would be really appreciated. I’m also planning to run more benchmarks and memory checks to ensure stability. Thanks for your time and support!

This situation is entirely your own doing. High-end coolers such as the upcoming Noctua NH-D15 V2 and Scythe Fuma 3 should manage it well. A regular 360mm AIO works if you adjust the power settings and undervolt it a bit. Hyper 212 isn't sufficient on its own. The 6xx series boards have decent DDR5 support, while the 7xx series performs better. Still, running four sticks in DDR5 remains challenging for both AMD and Intel at the moment. If you require more than 64GB of RAM, consider the new 2x48GB kit to reach up to 96GB, or check your board's specifications.
