CPU overclocking causes crashes in games, yet not during stress tests.
CPU overclocking causes crashes in games, yet not during stress tests.
I didn't say you have to, but it's just a thought for later, especially with the new GPU.
If the system stays stable while running both CPU and GPU at the same time, the PSU isn't the issue.
Your setup should use around 200-250w during gaming.
The lack of crashes at 4GHz suggests the problem is related to overclocking.
Components wear down over time, so stability can drop even if settings were fine before.
Try adjusting the voltage manually—find the highest stable frequency up to 1.3v (ideally between 1.2 and 1.275v)—then reduce it slightly.
That's generally the best approach for long-term overclocking.
To achieve 144FPS, an i7 CPU would be more suitable for many games. When reviewing CPU/GPU usage, you’ll likely notice the CPU is at full capacity while the GPU remains significantly lower (especially at low settings). Auto voltages are not a good solution. Each application utilizes different CPU components—multiple cores, cache, memory controller, I/O, etc.—so an overclock might cause instability under game load, even if stress tests succeed. It’s advisable to test games and use the system to confirm stability. If you encounter BSODs like “WHEA_UNCORRECTABLE_ERROR,” reduce the overclock. Look for a CPU that remains stable at around 1.3v. Also, many games gain from RAM overclocking. Keep in mind that memory overclocking affects both speed and latency (timings). The crash issues during games could also stem from the power supply unit, especially when stress tests are applied. Try running AIDA64 and FurMark/Heaven together to observe the effects.

Keep in mind that memory overclocking affects both speed and latency (timings). The crash issues during games might relate to the power supply unit—especially when running heavy loads. Try running AIDA64 and FurMark together; good temperatures and no crashes were observed at over 140fps on FurMark at 1080p with my Overwatch session (not CPU-heavy) and around 85% usage for Battlefield. I lowered my OC to 4GHz and it remained stable, even in the old rig. I might consider updating the chipset driver since I switched to SSD storage on Windows 10. While an i7 isn’t ideal, my i5 performs well without GPU bottlenecks.

Notes:
I didn't insist you must do it, it's merely a recommendation for later. Particularly with the new GPU. If the system remains stable without crashes during simultaneous CPU and GPU stress, the PSU isn't the issue. Your setup should use around 200-250w while gaming. The lack of 4GHz crashes indicates overclocking is likely the cause. Components wear down over time, so stability can drop even with settings that worked well before. Please consider adjusting the voltage manually. Aim for the highest stable frequency up to 1.3v (ideally 1.2-1.275v), then reduce it slightly. That's a common approach for long-term overclocking. I'll give it a shot, thanks.

Also, updating your BIOS might improve stability, especially since your current one is two years old.
It seems beneficial to update the BIOS for better performance.
Avoid using AUTO, as it increases voltage beyond what's necessary.
Probably it would be wise to install the most recent BIOS. It could improve stability. Just avoid using AUTO—it raises voltages much higher than necessary. Thanks for all your assistance!
Merged version:
The user reports that their overclocked CPU causes game crashes. They mention previous stability at 4.5 GHz, but after changing PC cases, games freeze and the system slows down significantly. Despite stable stress tests and temperatures in the mid-60s under load, performance drops to the point where manual restarts are necessary. They note no issues with stock settings, but struggle to run most games at 144fps. They’ve adjusted voltages and clock speeds without success and suspect excessive thermal paste application.
I faced a comparable problem while working on my OC. I set my RAM and NB too high, which affected the bus frequency (this was for FX 8370, though it might differ for Intel). During bench tests it worked, but it failed after a gaming session got hot. Good luck.
