Underclocking a reference AMD 6950 (2gb)

Voting troll.

In all seriousness, can't see why anyone would want to do this with a high end card anyway, if it wasn't being used for gaming then fair point, but you'd be best off just selling it for a 5770 or similar.

Any further on the underclock?

Wait, I dont get this thread.

....Wtf.

News on the underclocking guys.

I've just spent the last 8 hours trying to underclock this whilst keeping a good temperature. I actually hit 52*C at one point, but managed to get it to run at a cool 38*C. Again though, the fan had to be ran at 100%.

But heres the results..

100% fan speed at 200mhz clock speed. What pointlessness is this? Still that is a much better underclock. I assume this is in full 3D mode?

Go even lower. You might even get it running sub-ambient

Modding might help. Try removig 1gb of ram with a flat head screwdriver.

deusexlumina · 10 Apr 2011 at 10:44

This is ridiculous. Buy a 4350 if you want those clocks. If you want to lower power consumption, you should be undervolting

Steves1982 · 10 Apr 2011 at 10:48

No need for 100% fan speed, especially if underclocking.

Why are you doing this again?

PapaLazaru · 10 Apr 2011 at 10:51

Surely there is NO point in underclocking a GPU? What am I missing? I sometimes underclock my CPU, but it is a painless one button process which just makes my web surfing silent, as it turns all the case / cooler fans off.

sjcf1 · 10 Apr 2011 at 10:52

You do know these cards can go close to 100 degress without any problem whatsoever? 52 degrees isn't hot.. why are you doing this again? Just to see how cool the GPU can go?

Surely if the card has a large change in temperature quite quickly, your underclocked mode to the normal mode which will make more heat that can't be good for the card either.

If I had to describe this thread with an image this is what I'd choose

powelly · 10 Apr 2011 at 13:59

confused.com?

i don't get it, why would underclocking a card make it hotter? surely it would be a lot cooler, and you wouldn't need the fan on even 20%? :confused:

mind = blown :confused:

You know that underclocking is really risky right?
If you run it underclocked without changing the stock voltage it can fry the card...
Thats why the temperature hasnt scaled with the underclock. Your pumping the same volts through transistors that are changing on/off states at a reduced rate (75%).
Be careful or you may end up with performance degredation or even worse a dead card.
The warranty is also voided by underclocking, because of the previously mentioned reasons.

The Asgard · 10 Apr 2011 at 16:16

Why would you underclock and run the fan at 100%. The person either does not have a clue or it's a complete windup.

My money is on it being a windup.

Awahwah · 10 Apr 2011 at 20:41

I don't get this thread, I must be missing something - I'm told that all time by the Mrs

SeeknDestroy · 10 Apr 2011 at 21:05

Have you tried putting 2 of those underclocked cards on crossfire running both fans at 100% every time the garden seems overwhelmed by leaves

?

Seems like a good idea!

ahenners · 10 Apr 2011 at 21:45

Careful. Any further underclocking and you might need to put it under water or LN2 :rolleyes:

drifting · 11 Apr 2011 at 13:23

Should probably add how you reduced the voltage in order to reduce the temperature as well

This thread made my day lol

Thallium · 11 Apr 2011 at 18:56

Have i got a gas leak in the house? or is the OP saying he has UNDERCLOCKED his card. lol

Hay 25! i have your next unclocking challange... Buy a 990x and see if you can get it down to 100mhz.. That will be so cool. THEN send it to me when your done and i will see if i can beat it.

You must have the biggest waste of time post i have ever seen.

Can you please explain to us all WHY you would want to spend £200 on a card and make it run like a £40 card?
