Undervolting my Xeon X3350.

post #1 of 2
Thread Starter 
Just got my X3350 in mail today, and I installed it into my machine.

A few questions, though:

1. Why is the temperature on Core 0 so high? It's at least ten degrees higher than all the other cores, even at idle.

2. I am also trying to undervolt my X3350. I don't overclock, and since this is a quad-core, I am undervolting to conserve electricity and lower temperatures. I set the voltage in the BIOS two notches down from its default voltage of 1.175, at 1.0625. However, when I ran Prime95 to see if its stable at that voltage, CPU-Z tells me that the voltage is 1.04 volts! (This is my first time undervolting, by the way.)

I love my new X3350, though. Bad Company 2 shows the greatest performance benefit.

1. I had a similar case before where 1 core had a big delta compared to the others. I actually re-applied TIM (you need to make sure you are using the correct method for the type cooler you have, in my case I had to use the two line method on my HDT cooler) and re-seated the cpu cooler. This resulted in my cores being 2~3*C within each other. Also is your cooler completely flat and in contact to the cooler, there have been cases where the cooler is concave which made the CPU cores have different temps.

2. As for CPU-Z not reporting the actual BIOS voltage you set is something that is commonplace, no software can be 100% exact when reading temps but it does give you a good idea of where you're at. Have you also adjusted you TJ max values correctly?

Enjoy!
