ATI 4850 TEMPERATURE discussion

Page 6 - Seeking answers? Join the AnandTech community: where nearly half-a-million members share solutions and discuss the latest tech.
Got my parts in last night and assembled everything. With an 80mm exhaust on the side of the case i was getting 71C idle and 80+ Load. Installed a Zalman VF-1000 and overclocked to 690/1100. Idle the card is at 38C and jumps to 50C under load. I am on the fence about using radeon bios editor to OC further. Seen a couple people with 800+ clocks on air cooling.

So now, this card has an Accelero S1 Rev 2 on it, with a 140mm Yate Loon fan to cool it. It even runs fine passively, it idled at 50c and loaded at about 68c. Still, I like to keep stuff cool, and a 140mm fan wasn't going to add to much noise, this thing is still quiet. I also purchased some Zalman ramsinks, for aesthetic reasons mainly. :thumbsup:

Nice work! The 140mm fan is quiet and the card looks great. With that setup you'll remain cool for sure. If you decide to, you'll be able to oc that card to 700 core 1100 mem no problem. Let's see what they do with 4850+. Wherever they take it, you'll be able to take yours too...

Yes, the 140mm fan really didn't make much difference in terms of noise. I'd already run it passive cos I knew it'd be okay that way, given the original temps on the stock cooler. So I was wondering whether to bother with the fan. Glad I did now. Just wanting some better overclocking tools to come now, as well as some newer drivers, although the 8.6's with hotfix don't do a bad job at all.

Wasn't comfortable with the original temperatures. I know AMD said that these chips can run at high temperatures, but surely they're more efficient when they're nice and cool.

It's overclocked slightly now, 675mhz on the core and 1050mhz on the RAM.

What a card. And what a cooler, great shit. 🙂
 
I was searching around Guru3D forums and found this great workaround from one of the users.

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 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.
Good Luck ,bretware


I set my fan to 55% and my idle temps drop from 74c to 49-50c! Anything above 60% is kinda loud though. But this is a great workaround until the fan gets fixed.

Amazing find - set my fan to 60% using this method, dropped my idle from 80c to 52c, load at around 60-62c

This works great. I created a desktop icon and put it in "start up" so far 55% dropped he GPU temp to 57 C at idle
 
That workaround for the fan speed issue is almost the same kind that was done initially for the 3850/3870 cards. Glad to see the same sort of edit is working for this generation of cards, too.

Great find indeed. No hardware mod necessary, perfect for those who are hesitant to do so. Good job friend..

 
I don't seem to have a C:\users file...

Windows is installed on my "D" so I looked there obviously. I must be missing something? I'm new to ATI and have the CCC that came off the driver CD with my MSI card. Are all of you using the "Hotfix" driver off the AMD website?

C:\Users is unique to vista I believe, if you are running XP it would likely be under C:\Documents and Settings\UserName\ etc. etc.

Been awhile since I've had to dig through XPs folder structure so someone please correct me if I'm wrong.
 
I have a question... is it possibile to put 2 x 4850 cards in CF, but with both of them having a Arctic Cooling S1, rev2 on them with a 120mm fan?

you are right. That is the structure for XP.
 
For fellow XP'ers it's under C:\Documents and Settings\"your computer name"\Local Settings\Application Data\ATI\ACE\Profiles.xml

I'll have to give this a try myself as idle temps of 77c bug me, but coming up from an 7950 GX2 with high temps too doesn't scare me.

EDIT: Changed the two setting with awesome results. It was set at 24 and I changed it to 50, rebooted and I watched the temp drop to 49c within a minute. The fan is a little louder now as I have the side panel off but during a game session I'm sure I won't hear it. Now I can try again the ATI Overdrive, I did it before with decent results but had artifacts all over the place so I reverted to default speeds. Highly recommend this for anyone concerned about temps!
 
I wonder how many RMA will be submitted if people are starting to flash their cards with the MSI bios??? This is a bit lame for manufacturers to be releasing cards like this.
 
Bah, thanks for the replies. I still can't seem to find the "Local Settings" folder even when I search for it on all my HDD's. What version of CCC are you all using?

Do you have to wander in and threadcrap all conversations that show positives about AMD/ATi?

And I seem to recall the 8800GT was released with an absolutely shitty fan that they had to change before the temps were brought under control, they couldn't just fix the BIOS + adjust fanspeed like with these cards.

@SteelSix:
Thanks for the great work here. I'm probably going to go the VF900 route myself instead of the S1 because it's a much smaller setup and I don't have to cut up the stock hsf (so I could still potentially take advantage of the lifetime warranty if something goes wrong down the road). I suppose you could also use an S1 with ramsinks on the PWMs instead of cutting up the stock hsf?
 
I have an x1950xt that has been getting worse as far as artifacts go; I tried using the manual fan speed setting per this thread but it's obviously still on manual control. It sure seems to be a temperature issue (mostly?) since Oblivion would lock up within minutes when it was hot the other day (~85F in here). Now that it's about 60F and the case cover is off it ran for a good 30 min before getting a bunch of artifacts.

There was no manual fan speed feature setting in the .xml file generated by saving a profile so I just pasted the whole block of text (from above) in there.

Does anyone know if this should work? I'm running on Vista Business x64 with the most recent drivers from ATI/AMD's website.

Oh, and I have a 4850 on the way to replace this thing... hopefully it handles better than this guy does.
 
You should be able to modify your bios with rabit and flash with ati flash. I did that with my x1900gt, back in the day.
 
I got in on the BB deal for 4850 a week ago; and from the onset, the card was running uncomfortably warm; at a sweltering 78C when idle, and 85+ when under load.

But I can attest to a solution that probably someone has already mentioned in the thread:
http://www.newegg.com/Product/...x?Item=N82E16835114024
This actually did a dramatic improvement on the card's cooling situation. Just adjust the fan speed on the PCI cooler to high, and you would see the temps drop steeply. Now it is running at 60C when idle, and 72+ under load; not bad at all for such a simple 30 second solution.
