CPU and GPU overclocking issue
CPU and GPU overclocking issue
Through numerous tests, I've observed that I can only reach maximum CPU or GPU overclock. After trying to overclock both, the system would crash. However, when only one component is overclocked at its peak, everything works properly. My question is why I can't do both at maximum. My initial thought was insufficient power, but I believe the 650W power supply should be sufficient for a GTX 460 and an AMD Phenom triple-core CPU.
It is a single core that can be unlocked to a dual with 4 logical and 2 physical cores. Your CPU is low binned, partially functional, and may be warped or deformed at the nano layer. This means it is only rated by the manufacturer to operate at stock speeds and cannot exceed its factory specifications.

heat, heat, heat, heat and more heat.
I don't think so. According to nvidia's site the gpu's max temp is 100C and mine mostly sits at around 55-60 under load. Right now I'm with running only with max cpu overclock and it reaches 70C with prime95 but it is stable. I've had it run for 10 hours a couple of times and it didnt crash.
power supply isn't just about wattage. If you push it to its limit, it won't deliver a steady flow of clean power to both the CPU/GPU, which could cause crashes. The same applies to the motherboard phases. If you share more details about components, temperatures, and clock speeds, we can assist further.

Please list full PC spec including make and model of PSU. 600w is meaningless without knowing the quality of the unit

Couldn't locate much information about that PSU, but it supports the common trend of these unidentified brands. It seems to be a low-quality unit. Avoid trying to overclock low-end PSUs, as failure might harm other parts. A higher-tier model would be better for overclocking, though a tier 1 unit is preferable if possible.
