Overclocking core 2 quad q9300
Are the temperatures monitored by Prime95 or another application or game? Prime95 can strain your CPU more than other programs. Do you have adequate airflow in your case?
If Prime95 delivers the results you expect, other programs will suffice for you.
Salman Soomro asks about increasing overclocking further. He explains that to achieve higher frequencies, adjustments to the build are necessary, such as improved cooling solutions. He notes the distinction between CPU temperatures—Tcase and Tjunction—and mentions that a 5°C difference exists between them. He clarifies that if the RealTemp reading is lower than expected, it indicates a cooler Tjunction, providing some flexibility. He also inquires whether the Vcore was altered during the overclocking process.
Barto:
First of all, overclocking is a process that requires trial and error. When you increase the clock speed, you test it and adjust accordingly. It’s not something you can simply set and forget—it demands patience. The main constraints are temperature and stability. Personally, I avoid temperatures above 70°C, which is a reasonable threshold. High heat can harm components, and usually, when temps rise too much, the motherboard will automatically slow down the CPU and eventually shut down the system. Instability, like erratic clock speeds, can also lead to crashes. Also, don’t expect your processor to perform at superhuman levels; each chip behaves differently. Just because someone else managed 3.8Ghz with the same CPU doesn’t guarantee the same result for you.
You’ll need a temperature monitoring tool. I recommend RealTemp—it works well and can be found here: http://www.techpowerup.com/realtemp/ I also suggest CPUZ, which provides core clock and voltage information: http://www.cpuid.com/softwares/cpu-z.html
It’s important to note that the Core2 processors differ from newer i-core Intel chips. You’ll need to adjust the Front Side Bus (FSB) when overclocking a Core2. The i-core processors change their multiplier settings. Your CPU typically has a default FSB of 333 MHz with a multiplier of 7.5. Multiplying these gives the core clock—so 7.5 × 333 ≈ 2497 MHz, which is around 2.5Ghz. A good starting point for overclocking would be about 3.0Ghz. If you aim higher, you’ll need to learn more about the process.
Regarding memory, avoid overclocking it either. The standard speed for DDR2 modules should be used as your maximum setting. For example, if your RAM is 800MHz, halve that number (800 ÷ 2 = 400 MHz). This is because memory performance is tied to the FSB. So a DDR2 at 800MHz can only run up to 400MHz on that bus. If you think you can push it to 533MHz with your current multiplier, you’d need a clock of about 4GHz (7.5 × 533 ≈ 3999 MHz). That’s quite ambitious and would require special conditions like water cooling or luck.
Now, considering the CPU’s FSB—some sources say it’s 333MHz, others 1333MHz. I’m not sure if that’s correct. Could you confirm your CPU’s actual FSB value?
