Thread: Solving problems in new HD4800 temps

As you know, the new Radeon HD4800 is a great VGAs with a price / performance than ever before and able to give you many headaches to Nvidia.

However, these new VGAs have a serious problem with the operating temperature, since the regulation of the fans that incorporate not just a marvel. In many cases, core temperatures ranging from 70-80 º C at idle and 100 ° C at load, and for system users in the crossfire situation is even worse, because the card receives the lower most of the fresh air of the box but largely blocks the air at the top.

While awaiting the departure of heatsinks capable of taming these beasts, I will teach you how to create profiles in the Catalyst Control Center (the CCC) that will allow you to control the rpm of the fans and improve the temperature of your brand new graphics.

Once installed the drivers and CCC, the first step we need to do is go to the tab "Overdrive." It is before us the parameters of the frequency of the nucleus and the memories of our graphics, a part of the operating temperature of the core. From this tab, if you wish, we can do to OC the card. Also you will see that while the core of the graph is at rest, the frequencies of core and reduce the RAM so that the graph consumes less power and less heat.


In the picture you can see that my top card (which is connected to the monitor) is a warm 82 º C in idle, while the bottom is at 73 º C.

The first thing we do is turn on the box that says Enable ATI Overdrive.

Then, at the top click on the tab "Profiles" and select "Profiles Manager".

In the new screen that will open in the first box type the name you want for our profile in the 'Composition', select the option "all Catalyst Control Center settings" and give to "Save".

Now that we have created the profile, we have to edit it. To do this, you look at the following address:

C: \ Documents and Settings \ your user name in WinXP \ Local Settings \ Application Data \ ATI \ ACE \ Profiles

The profile appears as an XML document that can open the notebook without any problem.

Once inside the profile, look for the following lines:

<Feature Name="FanSpeedProtocol_0">
<property Name="FanSpeedProtocolProperty" value="Percent" />
</ Feature>
<Feature Name="FanSpeedAlgorithm_0">
<property Name="FanSpeedAlgorithm" value=" Automatic "/>
</ Feature>
<Feature Name="FanSpeedRPMTarget_0">
<property Name="Want" value="0" />
</ Feature>
<Feature Name="FanSpeedPercentTarget_0">
<property Name="Want" value=" 24 "/>

The value that says "Automatic" is changed to "Manual" and where it says "Want" value = change for the figure you want, bearing in mind that this figure is the% of the rpm of rotation of the fan.

Users of Crossfire systems must modify a second series of parameters:

<Feature Name="FanSpeedProtocol_1">
<property Name="FanSpeedProtocolProperty" value="Percent" />
</ Feature>
<Feature Name="FanSpeedAlgorithm_1">
<property Name="FanSpeedAlgorithm" value="Manual" />
</ Feature>
<Feature Name="FanSpeedRPMTarget_1">
<property Name="Want" value="0" />
</ Feature>
<Feature Name="FanSpeedPercentTarget_1">
<property Name="Want" value="30" />

As you can see, changing the extension _0 (VGA primary) _1 a (secondary VGA).

Done all this, and keep the notebook shut, go to the CCC -> Profiles and actives your profile. In my case, a simple increase from the original 24% to 30% causes the temperature of the main VGA drop of 82 º C to 68 º C on the desktop, a notable decrease by more than a negligible increase in loudness.

Dread very good!

I hope to produce new graphics, like the ati you posted, but they consume much less and so the temps are lower. Still generated as these show that they eat as if nothing 300W are managed with the invoice xD.
What he would get these results:
Full load up to 100W
Range
50 ° C LOAD
It would be something phenomenal.
So where will the consumer ...
PS: In the winter, with everything closed, you get to play for a while and the computer to make you cooler. In summer it becomes skillet

Very good work as always dread ... segue asi.... Look I have no HD4800 but I am sure some day this will provide useful tutor

salu2

I have an h4850 and I do not give much temperature ... you mean these models target? Activate 0 to 50th thanks to this.

50th will give you because you've increased the rpm where the car left the VGA low of 70 º C.

Thanks Dread, as always, you are the salvation of many.

Nope, I came to these values and now I've put it in the range of temperatures, as ye see?

Terrific manual change of the revolutions followed him to the letter and gives a great result.

I have one card and you put what you call speed by 45 percent, if not be much. You tell me.

The case is that it is virtually fixed at 49 º, 50 º 51 º Celsius.

But this morning I happened to put the program Everest shows that practically all of the sensors and see that the revolutions of the fan are 4200, 4300 rpm. And suddenly it occurred to me that I do not know if it will be too.

Cooling Fan: 4269 rpm GPU at the moment,

It would appreciate if I could get out of doubt.

Thank you very much.

"A lot of" what will determine your ears. For me, 40% and represents a fairly sound, so 45% is not that I am raising. On the other hand, are not the same 45% in a 4850, which is quieter than in a 4870 which is quite noisy?

Still, better use the GPU-Z to check the rpm of the fan sink your VGA, a part of the time since the Everest not going to show all temp sensors that leads the chart.

Thank you very much.

La mea sapphire is the HD4850. Rioja noise and I realized that generates a little more but is under a desk because he had not done much, only looked at the temperature from time to time in the catalyst.

Then think to set up a 40 and although a little more temperature at 55 or 58 would be good, where below 60 at rest.

And this program tells me that since I'm going to try to give them a try, do not know.

Un Saluda.

Edit: I attached the picture that gives me the GPU-Z, the two screens to see what you think and I suggest that I change, I do not want humpback.
