Adjust performance settings on a Core 2 Duo processor.
Adjust performance settings on a Core 2 Duo processor.
Consider starting with "ai overclock." This method attempts to automatically adjust a stable overclock. You'll need to upgrade your HDD to an SSD for better performance. What type of CPU cooler are you using? Have you refreshed the thermal paste?
Probably that stock cooler limiting the overclock then. There needs to be thermal headroom. Be careful with temperature with these old CPUs as they aren't nearly as good as protecting themselves from overheating as modern ones. I had an i5 2500k that fried itself to death when I forgot to plug in the CPU fan during troubleshooting.
