Overclocking can have an impact, though its effects vary depending on the system and component being modified.

If you want to overclock your CPU to a higher standard, it may result in a better frame rate in games. However, whether you need to overclock your memory depends on the situation.
Using an unlocked CPU allows you to increase its speed independently. With a locked CPU, boosting the bus speed (BCLK) also leads to higher RAM speed. Having an unlocked CPU definitely impacts performance.

With an unlocked CPU you can simply increase the CPU speed independently.
With a locked CPU, when you raise the bus speed BCLK, the RAM speed also increases.
You have an unlocked CPU – yes, it will definitely affect everything.
As the CPU MHz goes up, the RAM speed follows suit.
But my RAM is limited to 2133 MHz, so I can't really overclock it.
Perhaps for my next system I'll buy in a few years.
I could get higher frequency components.
But I need to be sure that overclocking actually makes a difference.
When you increase the BCLK, your RAM performance will improve. If you only boost the CPU multiplier—something possible on K series processors—only the CPU itself will see a speedup.
I’ll share a few examples from older setups. They’re still useful thanks to overclocking.
LGA775 QX9650 unlocked CPU in a Dell T3400 workstation.
Base clock CPU score 41%

QX9650 at 4.15GHz OC CPU score 57%, above average. RAM timing remains unchanged.

Dell T 3500 X58 workstation with unlocked XeonCPU.
W3690 base clock CPU score 67%

W3680 with OC likely at 4.3GHz (OC in Windows) CPU score 82%

All these boards use locked BIOS motherboards, are 8–10 years old, and still perform well.
The DDR2 RAM in the T3400 is quite outdated, but the X58 models featured 3-channel DDR3 1333 which can still deliver solid results.
William P shares his thoughts on CPU and RAM performance adjustments. He explains that increasing BCLK can boost RAM speed, while raising the CPU multiplier—available on certain K series CPUs—will primarily benefit the CPU itself. He provides examples from older systems, noting that overclocking still offers relevance. Several unlocked CPU models are mentioned, including an LGA775 QX9650 in a Dell T3400 workstation, a W3690 with 67% score at 4.15GHz, and a W3680 with an estimated 4.3GHz under OC settings. He emphasizes that all these boards use older BIOS and still perform well. He also mentions the aging DDR2 RAM in the T3400 and the continued viability of 3-channel DDR3 1333 in X58 systems. He concludes by expressing gratitude for the advice, planning a basic setup due to GPU overclocking and uncertain component longevity, while aiming for smooth gaming at high resolutions with high settings.
Well, you wanted to know if overclocking is beneficial. It can actually prolong the lifespan of your current hardware for many years. Some individuals have created Overclocked Dell T3500 models for as low as $130, including a CPU and overclocking. This means you could achieve similar results at a significantly lower cost. If you're not in need of it or prefer not to proceed, then it offers no real value.
