How do I underclock my vid. card?

[Kitomaru]

Yarr, montag recommended me to post here and ask. Pl0x help me? =(

P.S. I need to UC for heat issues =/

Get coolbits, and just...underclock it. Coolbits opens an OCing option in the Nvidia control panel thing (if you didn't know). Just move the sliders to the left to underclock it.

personally, I'd look into an aftermarket cooler, like the Zalman VF700 for heat issues

...I dont really get how to use coolbits...=(

Download and install coolbits.

Downloading it should take less than 10 seconds. Installing it should take less than 10 seconds.

Go here in your Nvidia control panel.

Move slider along lines.

Test overclock.

Apply with startup.

*sigh* new problem, I underclocked my default 490/1350 to 200/500 even, and still froze up X_X

I believe it is a temp. prob, any recommended cooling systems?

Don't put the core that low... 200MHz is WAY TO LOW Underclocking can cause it to freeze too. Try it at like 400Mhz and see if its okay.

Either way I would send it back or get a Zalman VF700 or a NV silencer 5

In lieu of that, if it's still freezing, it's likely not a temp problem. RMA the card.

do you have enough juice feeding that beast?

what psu are you using?

make sure the 12v rail is dedicated to the card only

Doesn't underclocking void the warranty?

I think this sounds like a power supply problem.

Thinking the same.

i had problem with my sli setup when my 12v rails weren't dedicated to the 2 cards and the motherboard

How do you know if the 12v rail is dedicated to the video card? It isn't stated in my manual.

 

[biostud]

how high temps do you get?

I'd imagine make sure that the lines the motherboard and video card are plugged into don't have anything else plugged into them.
