Windows – Should I overclock a dying PC

cpuoverclockingwindows 7

I have a laptop (Compaq Presario V5000). It's about 4 years old now. My dad bought it at Walmart on Black Friday for $389 (it only had 384MB of memory (now it has 2GB)). It has seen 3 Windows OS's and 4 Ubuntu's (I dual boot). The hard disk has begun to fail. I already have all the data backed up.

I wouldn't say my computer is slow, but I wouldn't say its fast either. The processor is a Mobile AMD Sempron 3300+ which runs at about 2.0 GHz. The current tempature after being on for about 6 hours is 43 C (or 104 F).

So I'm just wondering:

  • 1) Should I overclock it?
    • 1 a) If so, how much?
  • 2) What is the max temp I should allow it to reach?
  • 3) What kind of performance boost would I see (I do a lot of programming)?

Best Answer

Overclocking a laptop is a risky move, overclocking this particular laptop is more.

As you know, most laptop BIOS don't support overclocking and heat-dissipation will be a real problem as well. Moreover, a few more MHz don't mean substantially better performance.

I suggest for you to replace the HDD. A new HDD with higher RPM and a better cache would make a real performance difference, you could look at (for example) the WD Scorpio Black.

So responding to your answer:

  1. No, you don't; and probably you can't

  2. CPUworld says 95°C is absolute maximum temperature

  3. If you replace the HDD, you would definitely see a performance boost, especially boot times and file access
