I just overclokced my CPU. Need advice.

Hi everyone,

I have the following system specs

Intel Core 2 Duo 2.0 GHz
DDR2 800MHz 4x2Gb RAM Memory
Nvidia 9800GTX+ 512Mb GPU

with the above specs I had a Vista experience index of 4.8 which was capped by the CPU. Core 2 duo didn't come cheap when I built my PC then as it was just released.

CPU : 4.8
Memory : 5.3
Graphics : 5.9
3D gaming : 5.9
HDD : 5.9

Now instead of buying another CPU I overclocked my CPU from BIOS.
So now I have an equivalent of Intel Core 2 Duo 2.4 GHz CPU. That is a 20% increase.

This boosted my Vista experience index from 4.8 to 5.3 out of the maximum 5.9.

CPU : 5.3
Memory : 5.3
Graphics : 5.9
3D gaming : 5.9
HDD : 5.9

My question is: Is it safe to overclock my CPU for as much as 20% without installing additional cooling hardware?

Thanks

Doh after further testing it seems the overclocking was not that stable. I revert back to default clock but set the enhance performance in BIOS setting to extreme and got the same Vista index of 5.3.

Hmmm I don't think I want to spend money on getting a new CPU for now. This will have to do until I decide to get a new rig in some distant future.

while overclocking I monitored my CPU and GPU temperature.
with overclocking CPU temperature at idle is about 50-55.
Without overclocking CPU temperature at idle is about 37-42.
So there's a big difference there and not to mention I use my PC in a tropical climate in a room without aircon being turned on most of the time.

Anyway I'm getting the same Vista index increase by just changing a BIOS setting without having to resort to overclocking and without having to worry about the increase CPU temperature so for now I say no no to overclocking.

Thanks anyway.

Try running Super Pi on the highest setting and see if any errors come up, if its clean ur stable and clear

Any overclocking may cause the system unstability and deffinetly will shorten its lifetime..

I don't dare to give overclocking a second try after I found out that without additional CPU cooler, the temperature would go at least 10 degree celcius hotter. No way. And I can't add a CPU cooler since I've used all the power cables!!

Thanks to that 9800GTX+ which needed 4 power cable plugs!!!

Anyway I'm not planning to start WWIII from my PC or to launch and track a space shuttle so...it will do just fine

for a couple years.

Just remember - vista maxed out initially at 5.0 - then with the sp the max is 5.9

5.3 aint shabby on that scale.
