How CPU Overclock works?
How CPU Overclock works?
Hello, I have some concerns regarding my overclock on an AMD Athlon II X4 620 (2.6 Ghz Stock). It was increased to 3.00 Ghz using FSB. The processor is locked with the highest multiplier of 13, and the stock FSB is set at 200 Mhz (I added 31 to a total of 231Mhz), while the stock voltage is 1.404 Vcore. There is a multiplier for the HT Link, which I reduced to 9x = 2080 Mhz, but there is no multiplier for the NorthBridge; it only has a fixed speed, even when set at 1800 it still runs at 2300Mhz. I have observed that other users with similar Athlon models use much lower voltages on this chip. I attempted to undervolt it, but it seems my motherboard doesn’t support that option; I can only increase the voltage (Foxconn A88GMV AM3). I tested Prime 95 for two hours, and it remained stable. I have been using it for the past two weeks without any stability problems while gaming and surfing. I am using a tower cooler LC CC 120, and the CPU temperatures never exceed 40°C. I also have one fan directly on the VRMs and MOSFETs.
Now, the question:
Could this affect the motherboard or CPU if it remains stable at stock overclock settings?
I understand that increasing voltage, especially on low-end motherboards without a heatsink on the VRMs, can be harmful. However, at stock voltage, are there any risks for the motherboard or CPU?
Thank you in advance.

It's related to heat. If your VRMs become too hot, it can cause problems regardless of the voltage applied. Higher voltages also raise the chance of overheating the part, even if you use standard settings. Just because you're using regular voltages doesn't guarantee safe temperatures. You can purchase small heatsinks or attach thermal tape to the components to reduce the risk of damage.

Thanks for the clarification, that made sense given my previous thoughts. Regarding the heatsink, I plan to craft a custom one using an old GPU cooler, and I’ll attach thermal tape to secure it to the MOSFETs or VRMs as part of a side project.
