Looking to boost performance on Core2Duo E7500?
I need guidance on overclocking my Core2Duo E7500. My motherboard is an MSI G31TM-P21. I'm unsure how to proceed. Additionally, what's the highest clock speed achievable with the stock cooler? I have it and don't want to replace it.

What are the risks of overclocking? Warranty is well gone so no need to worry about voiding warranty.
A mild overclock hás little risks. You May have to jumper reset your MB if the overclock fails... Your system May become unstable...etc.. Older processos showed more risks (they could just fry without any warning). If anything Góes wrong, just reverr to standart settings and try again... If the CPU geys too hot it will reduce its clockspeed and you will LOOSE performance.. MY fathers Pentium was overclock for almost 2 years, and só is the xeon now. 24/7...
A simple way is to increase the base clock. Base clock * multiplier = CPU clockspeed. RAM will also overclock, so you must set it to on slower frequency beforehand. (eg 800->667mhz). I was able to push a pentium dual core e5400 (2700mhz) up to 3200mhz (13,5*237mhz) with the stock cooler. Above that it got too noisy.
Another way is to increase the multiplier.
Both can be used at the same time.
A shot of your BIOS options would be helpfull.
Also, since it is a dual core part, the performance may still be limited depending on the workload. I'd go 4C if you really want to keep this platform.
There are numerous helpful guides for overclocking. I ran my E7500 up to 3.4Ghz on a CM 212 EVO. The stock cooler didn’t perform well, usually dropping below 3.2 before I felt too hot. To increase it, you’ll need to access the BIOS and find an Overclocking or manual setting in the CPU configuration. The E7500 supports a maximum multiplier of 11 and a FSB speed of 266Mhz X4 (1066Mhz). Keep your RAM at its present frequency—possibly 800Mhz, though it might be higher—and adjust the FSB to 333 (1333) while setting the multiplier to 8.5 for around 2.83Ghz. Make sure your RAM speed remains unchanged before saving and restarting. After that, shut down, return to BIOS, and tweak the multiplier in half increments until the system boots without crashing. Then revisit BIOS and raise the CPU core voltage by 0.25 volts in steps until stability is achieved. You can try going up to 1600FSB, but be aware it widens the range of possible speed adjustments per multiplier and may limit performance at 1333 as reaching 3.66Ghz is likely the upper limit for an E7500.

Regarding the temperatures, I don’t want to fry my chip. I’m not planning a processor upgrade either. I’ll stick with this.
I understand you’re not interested in upgrading the CPU, even though we’re unsure why. If there was a good cheaper option available, would you think about it? You could get a lot more computing power for around $30 with a 4-core processor running at 3Ghz, then upgrade later.
The average temperature under load and while idle at normal clock speed should be specified in the documentation.
The expected average temperature changes based on location, room conditions, motherboard quality, and case setup.
I received my father a modified Xeon L5420 2.5GHZ with a Pentium cooler. It reached 7.5*400 MHz using an inexpensive HSF2 two years ago. The memory required a microcode update, but the overall performance improved significantly compared to the Pentium. I agree and would recommend it as well—I've installed many E5450 771 to 775 mods, and most didn't need the update either. The board is also compatible, making it a solid budget upgrade option.
