Your 4790k performed well at 4.8GHz with 1.275V and rock stability. After installing a new GPU, it became unstable at 1.26V but stable again at 1.325V. No other settings were changed—just the GPU swap. The temperatures stayed within safe limits, never exceeding 80°C.
It might have remained unstable at 1.275V, yet the weaker GPU didn’t provide enough power to trigger it. Alternatively, the issue could have developed gradually, and together with the first factor, it’s only appearing now.
Unstable when subjected to gaming demands? Check how near you are to your power supply limits. A stronger GPU might push it past its breaking point. Over time, parts like the CPU, motherboard, and PSU wear out—could be more than 10 years old. The 4790 card is likely quite old now. What about the rest of your gear?
We conducted various stress tests to verify the CPU's stability. This included normal operation and gaming scenarios, as well as specialized software that pushes all cores to maximum capacity. The goal was to determine if the CPU maintained performance under demanding conditions.
Prime 95 small ffts with AVX disabled worked well initially. After testing at 4.8GHz and 1.26V, I adjusted to 1.275V for extra stability. At that speed and voltage it remained rock-solid. The GPU changed from an RTX 2060 to a GTX 1070 Ti—still a minor step down—but it paid off with profit. My PSU is a solid 80+ Gold 600W unit, and temperatures stayed perfectly normal; the CPU never exceeded 80°C in Prime 95.
The most likely cause seems to be a power supply issue. It’s possible an unstable or overheating PSU could trigger clock watchdog timeouts and blue screens, even though your GPU performance looks normal.
It refers to a power supply unit rated at 80+ gold certification with a 600W output. The specific brand and model can vary, but common options include brands like Anker, Belkin, or Cowboy Power. The age depends on the manufacturer's specifications, typically listed in the product details.
