post #1 of 2
Thread Starter 
Hello

Sorry for bad English.


Hey all!

I am a really beginner at overclocking Only like heard of it etc.
So i did get a new Grahpics card Cooler By my Girlfriend and it looks really good, it is Akasa Freedom Force Cooler or something Like that.

The Grahpics card i have is ATI HD 4890.
and i am gona install the New cooler later too day.

So here is my question

Do you think whit that cooler i can overclock the Grahpic card alot more? then it is supposed too be.

Not sure How mutch i can i Push it, But i am thinking 10 or 15% extra Speed on everything?

have been checking some guides But i dont understand Mutch, any Hints on that hehe?

thanks alot

Kristian

I think you require a good vrm cooling, that means thermalright vrm r1/2. If akasa freedom force has enough room to accomodate that vrm cooler underneath, then go for it; otherwise I think your card may suffer instability issues due to overheating.
That was my previous experience, maybe yours will be much better though I doubt it. The card succumbs to overconsuming electricity if the vrms are hot, that results in cooling solution insufficiency easily. That means after a temperature point, you will need increasing fan speeds just to keep the card running; the problem is at the vrms not the gpu temperature.
