Overclocking

[Dan]

I'm a bit new to overclocking on the T-birds. (The last cpu I overclocked was a Pentium classic 75mhz to 100mhz) What I'm a bit confused about is the voltage setting. What is a general rule of thumb for voltage setting in relation to cpu speed?

I have a 700mhz T-bird on an MSI KT7 Turbo-R board, 256 mb pc100 sdram, 64mb Radeon, and a SB Live platinum. This is my fool around/mess around system, so I don't mind experimenting with it.

I currently have the cpu overclocked to 850mhz but without any voltage adjustment. I have a feeling that I might want to change the voltage setting. I'm sure I can overclock the cpu to 1ghz, but am afraid to since I don't know what voltage setting to use.

Thanks for any comments/suggestions.

Generally, it's best to adjust the voltage settings one step at a time until you find a stable setting. As long as you have good cooling, you shouldn't have any problems running higher voltage settings.

in general the higher you set the voltage the shorter the life of your processor will be.

what kind of cooling do you have? (your whole case, not just the cpu)

As long as you stay below .5V over stock, you are safe. In fact, some Thunderbirds work well DECREASING the voltage! (I'm not joking! Try it!)

Here's a sanity scale with regards to voltage, using a older-style Celeron as an example.

2.0V- No risk, it's stock, big deal
2.1V- Bring it on!
2.2V- Pfft...no sweat.
2.3V- Hmm...is it getting hot, or is it me?
2.4V- Feeling risky, are we.
2.5V- Okay, stop...STOP NOW!
2.6V- ARE YOU TRYING TO KILL ME?
2.7V- *Dead processor*

At 1.85V my PIII has only hit 58 degrees celcius-hot, but still in the operating tempertures. The stock is 1.65V My case is nice cool one (60cfm). Are Athlons that voltage intolerant?

58 degrees is way too hot for a Pentium III even under heavy load.

Bires,

That is INSANELY hot! What kind of cooler are you using? Even a average-poor one should to better. The cooler is probably not sitting on there right. You may want to use a copper shim.

...from the hardware to Asus PC Probe. The lowest threshhold that PC Probe will allow me to set for my CPU is 60 degrees. My airflow thermometer of the air out of the CPU cooler is only 37 degrees at a full load.

Also, I've found that Tribes2 taxes my cpu and video system more than 3DMark2001 and Prime. Isn't that wierd?

asus pc probe says my cpu temp is idling at 40c 104f, the loaded temp can reach 49c 120f, i am using a thermal take golden orb with artic silver thermal compound, i have been curious of these temps are too high... my voltage is currently set to 1.7v
my computer works a ok until i try to overclock my video card... my asus v7700 has not liked it recently when i overclock it

Asus pc probe is flaky and can give inaccurate readings.
