how important is the yellow wire?

[Sojuuk]

well i just noticed that at some point the yellow wire that feeds my 9800xt had not been plugged in. appearently it came out of the connector and didn't say anything. i assume this happened when i was installing my silencer3 prolly about a week ago. computer booted up and ran fine the only reason i noticed was because my intake fans which are also in the same chain as the 9800xt seemed to be going a bit slow. opened up the case and there was a loose wire i was like wtf!!!!!11

now it seems i am able to overclock an extra 15mhz.

did i do any damage by not running with that wire plugged in?

how important is the aorta to your body? what happens when you "unplug" it?

 

[starhawk]

owch.

 

[bpimmerman]

isn't the yellow used for fan speeds? arn't the red/black wires the important ones?

well me i would die, however, since my computer didn't die im assuming that corrilation is slightly erronious.

and im assume the yellow provides some voltage but not the large portion of it since all that was noticable was a lower overclock and slower fan speeds.

if the yellow wire (+12v) is unpluged and if it is used for the fans then if you remove it the fan should stop working... in a system that generates heat that must constantly be removed then it would be similar to a severe fever. One should try to overclock a card while disabling the cooling system.

i'm really suprised your card ran at all. if your card is working fine now i really doubt you damaged it.

The yellow wire is +12volts. This extra connector is used to supply extra current to the processor because of limitations of the AGP bus. I don't think it would hurt your card to run with the wire unconnected. It would still get 12 volts from the motherboard directly through the agp slot. However when using your card under a heavy load such as high resolutions and a very GPU dependent game you may have stuttering or lockups because of the lack of power. Also the amount of power used when overclocking is increased and that is why giving you card back the extra power allowed you an extra 15Mhz on your overclock. Your card is 100% fine and should not be damaged in any way.

isnt the yellow wire ground?

or maybe it is the 12 volt...

i rmbr when i was sleeving my psu, i had to take the molexes off, put the sleeving on, and then had a little trouble remembering which wires go where..... then i plug it all back in, turn on my comp, and smell burning plastic..there went my 120 gb.

inorder to prevent the yellow pin coming out from the molex, put it back and bend the little metal shoes, that way it tightens it up =D

Mos video cards pull mainly from the 5V rail, that is why this happened how it did.

 

[phaelinx]

The yellow wire is the +12 volt rail. All molex fans, hds, cdroms rely on that heavily. Although the devices *MAY* work without it..you are starving them and they may die ALOT quicker.

... they may die ALOT quicker.

What makes you think that? Unless it is affecting the cooling, it wont die any faster.

 

[phaelinx]

Not getting sufficient power.

@Talonz
There are two ways for the card to get power. If you cut off one of them, the other one will have to shoulder twice the load it was designed for. Worst case, you could burn out your mobo.

 

[Sojuuk]

well that didn't happen so im happy

 

[Grahxen]

Umm..

Yellow = 12V
Black = Ground
Red = 5 Volt

The video card draws off the 12v line not the 5volt. I dont even know how it posted without beeping? You sure mabey it wasnt just loose, but still plugged in?

 

[Sojuuk]

oh im quite postive it was floating around inside my case not attached to anything.

im surprised it didnt short out on the case itself.
