Voltage

[Guest]

Is there a way to know how high you can reach ( ghz)
with stock voltage?

Or buy how much to increase voltage if you are encountering stability problem with overclocking?

Also , what's the difference with the 5 different voltage?

does anyone know what they actually do?

Try pushing the CPU at stock voltage until you face stabiliy problems. Use prime95 stress test for stability test.

My Duron 1 GHz can do 1.1 GHz (220 MHz FSB) at stock voltage (1.75v). At 1.15 GHz/230 MHz @ 1.75v, it locks up within few minutes. 1.8v worked like magic in this case, now it can run prime95 stable for 12+ hours @ 1.15 GHz/230 MHz.

There's no specific need of overvolting. My Duron 1 GHz needs 1.8v (+0.5v from default 1.75v) to run stable @ 1.15GHz/230 MHz. But it's not stable @ 1.2 GHz/240 MHz/1.85v, locks up very quickly.

General CPU Knowledge updated ......... OK

A small voltage increase can cause a much higher temp. As you raise the voltage, you must keep a close eye on temps. You also reach a point where the leakage current becomes problematic. This will also show up as temp, but be much more dramatic. Heat will also affect stability. In other words, it becomes apparent very quickly when you are getting close to limits, so long as you advance slowly.

No problem with heat here , got a pretty good case .

I'm also planning on heating my room with my CPU alone this winter , save myself so electricity bills
