FSB voltage question?

post #1 of 13
Thread Starter 
Alright well in my 780i bios theres the fsb voltage. Im only slightly familiar with this.

Question is, will a higher fsb voltage raise cpu temps?
I have my fsb voltage @ 1.4v right now and im pretty shure thats too high for a q6600 at only 266mhz. Ill overclock later but for right now what should i set it too?

The higher voltage will raise temps. Right now, ive got a tiny OC on stock, and i actually lowered mine (voltage) to lower temps.

Alright thanks so the FSB voltage does raise cpu temps?
Cool..

Any suggestions on what i should have it running @?
Ive seen people say that they have it at 1.4v when overclocked so im assuming that i really dont need 1.4v.

Im just trying to figure out a increase of a few Degrees that has taken place ever since my 780i.

Im not sure how your bios is set up, but all my voltages are displayed in toggles. Just for a ref cause im a little fuzzy on what i set it to, but i think i lowered mine to around 1.2 v. Stress 'think'. If you have toggles, try lowering it by one (toggle) and run OCCT or StressPrime etc.

OH! 780i's run fairly hot. What mobo did you have before, or what are you comparing the temps to?

Yeh i figured.
Before i had a p5n-e sli.
My q6600 ran at around 38, 38, 37,30.
Yeh the fourth core is much cooler..... need to lap.....

Now with the 780i the temps are @ 41,40,32,39......still need to lap.....

When i lowered the volt, i went down to the low mid 30s. On a cold day sometimes a couple of the cores hit 28, idling of course.

Yeh its on auto, and its givin me 1.4v.

My vcore is currently 1.25v, and my temps should be much lower.
I dont wana oc till i can get them to idle a bit lower

If you do go down in volts, take small steps. I've been told that undervolting can damage components.
