The HD 4870/50 Thread

[Rich'[ard]]

i read on techgage that a new revision of the 4000 series may be coming out soon . they will have a revision of the core, which will allow higher core clock. this may then allow the current core clock to run at lower temperatures.

it says this right above the picture of the Asus 4850 fan picture.

anyone heard anything of this kind?

PS: "rumour" it says.

shamelesly stolen for another forum

if you make a profile in catalyst after turning on Overdrive( make sure clock and memory settings are correct). You can then go to the file "C:\Users\yourname\AppData\Local\ATI\ACE\Bretware. XML. the xml file will have the same name as the catalyst profile you saved. right click and hit edit.

<Feature name="FanSpeedAlgorithm_0">
<Property name="FanSpeedAlgorithm" value="Manual" />
</Feature>
<Feature name="FanSpeedRPMTarget_0">
<Property name="Want" value="0" />
</Feature>
<Feature name="FanSpeedPercentTarget_0">
<Property name="Want" value="65" />

Change the value to "manual" and Want value to "65"

Save the file then reload your profile in catalyst.

65% seemed perfect for me, 70% was loud but you may need it if your case has poor air flow.

You will may have to select the profile everytime you start the computer, but it will work until there is a fix or better info so i can figure how to change the auto target temp.

I sold one of my 3870's to get a couple 4870's. But I'm broke again, any word when the 1GB cards are to be released?

Well I got my Sapphire 4870 earlier this week and had to send it back to newegg as RMA due to card overheating within a few minutes of running Win XP. I could not even install the 8.6 drivers it came with before shutting off due to overheating. The entire PCB became so hot to touch that I thought it was going to melt. Obviously mine was defective. I will post reviews as soon as the new one gets here. I still use my Sapphire 2900XT daily and never had any issues with it, but this 4870 was disappointing.
