AMD Athlon64 4000+
9. Overclocking
In order to overclock the CPU, we manually started step by step to increase the HTT, beginning from the default 200 (2400MHz core speed), without messing around with extra CPU voltage. We checked the stability of the system with Prime95. When Prime95 started giving errors, we increased, by small increments, the voltage in order to stabilise the system. The highest value that we could get with no errors reported from the CPU was 227MHz HTT/ 2724.5MHz core speed.
- The Tests
Way above the FX-55. For some enthusiast gamers, overclocking this CPU to levels above the more expensive FX-55 CPU is very tempting. And overclocking it will surely improve the performance of the system, but we strongly advise against doing it unless you really need to.
Increasing the core voltage was necessary, and by doing this, the temperature also increased. Always check the temperatures that you get if you want to overclock this CPU. We used the Thermalright XP-90C cooling system and we got 57°C under heavy load, with the CPUs threshold being at 72°C.
