CPU Voltage ?

post #1 of 15
Thread Starter 
My CPU will run @ 3.5ghz with 1.28v but it wont let me run 3.5ghz with 1.35 volts. I thought CPUs always wanted more voltage. Would i need to increase or change something else. The reason is without my CPU taking more volts i cant gt a higher clock.

Any ideas?

More voltage = more heat and there comes a point where the voltage demand for the chip is outweighed by heat, or other limiting factors.

You may also need to play with CPU vtt and/or GTL voltage levels.

What cooling are you using?

Is it stable at 1.28? If so, what did you use to test it and why would you want to use more voltage for the same clock speed? Have you tried other voltages too?

Its Game Stable 100% (crysis) but Prime 95 crashes it. My main drive is that i can boot 3.6ghz or higher with 1.28v so i was wondering what was going on. And if i can do 3.5ghz @ 1.28v i should be able to do it at 1.35v no?

The more appropriate way is to see how much voltage is required for your CPU to be Prime95 or Orthos stable @3.5 and then see how much you need to get to boot andthen stable respectively at 3.6. There is no rule as to what voltage a CPU may need @3.6gGhz since each CPU is unique in relation to response in voltage increases.

it takes me 1.4v (after vdroop) to get 3.6GHz stable.

These chips take voltage safely up to 1.5... Just keep an eye on your temps! And yes, run stability tests that stress all 4 cores!

If it works with less voltage, I don't see why you would be complaining... LOL I mean I would love to be able to run that voltage and get that clock. The fact that more voltage doesn't work wouldn't even concern me if you happy with what your getting now.
