Since overclocking is defined as pushing a processor beyond it's normal safe limits by making certain modifications, overclocking can prematurely decrease the performance capability of the CPU. This is known as "CPU degradation". Overclocked systems can and often do naturally lose their overclock over the life of the system. As the CPU itself continues to operate, degradation of the overclock is not a cause for RMA. An overclock on a system is not guaranteed to remain. In fact, it is guaranteed to degrade over time.
How can you get it back? It is possible at times to tweak the settings of some systems to regain some lost overclocking. But this is rare and only delays the inevitability of further degradation. The most efficient way to restore an overclock is to replace the CPU with an identical CPU.Due to company policy, we do not offer overclocking instructions to customers.
