I've been running into some serious issues where specific applications like Chrome and Fortnite keep crashing on me. I've also seen Edge and Firefox crash occasionally. When I run an OCCT test for CPU and memory, I get errors on physical core 5 and logical core 11 after about ten minutes. Is there any way to resolve this without needing a complete CPU replacement? Could I disable those problematic cores temporarily? If so, how would I go about doing that? I'm also curious if this could be related to voltage issues. I tried using testmem5, and it didn't show any errors the last time I ran it.
To give you more context, I swapped in three different combinations of RAM, including two older 8GB sticks, but still got error messages. The only time I had a stable setup was when I used a single 16GB stick on my old motherboard, which is why I thought I needed a new one. However, even with my new motherboard and two RAM sticks, I'm still getting errors. Could my CPU be to blame, or might it be something entirely different? I'm really running out of options. When I was testing with the old motherboard, errors occurred, but I can't recall the specific combination of RAM I used then.
Here's my build:
- CPU: AMD Ryzen 7 5800X 3.8 GHz 8-Core Processor
- CPU Cooler: Noctua NH-D15S 82.52 CFM CPU Cooler
- Motherboard: MSI B550M PRO-VDH WIFI Micro ATX AM4 Motherboard
- Memory: G.Skill Ripjaws V 32 GB (2 x 16 GB) DDR4-3600 CL16 Memory
- Storage: Intel 660p 2.048 TB M.2-2280 PCIe 3.0 X4 NVME Solid State Drive
- Video Card: PNY OC GeForce RTX 5070 12 GB Video Card
- Case: Corsair 3500X ARGB ATX Mid Tower Case
- Power Supply: Corsair RM850x (2024) 850 W Fully Modular ATX Power Supply

You might want to look into your memory as well. Sometimes, even if the cooler is doing fine, memory instability can cause similar issues. Have you tried running your RAM through some diagnostics?
Have you tried different configurations with your RAM sticks? Sometimes mixing brands or speeds can lead to instability, so being consistent with your RAM might help.
Have you checked your CPU temperatures? Sometimes overheating can cause OCCT to throw errors. If your CPU is getting too hot, that could lead to the crashes you're seeing. It helps to keep an eye on those temps. Have your readings been stable?
Yeah, I feel you on that! My CPU started throwing errors when it overheated too. I thought my CPU cooler was malfunctioning, but it turned out one of the screws was loose. A quick remount fixed the overheating, and the errors stopped.
I checked the temps, and they’re good—never exceeded 65°C. I’ll run another test to be sure, though.
Yeah, I've tested memory before. I did testmem5 before and got no errors, but I’ll run it again just to be safe.
