5850 always downclocked

Recently after removing my crossfire configuration (from two 5850s to 1x 5850), my single GPU remains at a constant clock speed of 400MHz, 900MHz memory (goes up to 1000MHz memory during games).

However, the core still remains at 400MHz even during 99% load during gaming. It never goes to the 725 default core MHz according to GPU-Z, and my games are laggier than before.

The card worked fine before so I'm not sure what is wrong. I've reinstalled ATI drivers and recently installed the new 10.7 drivers.


Btw, I'm using two monitors, so the proper speed should be 400MHz -1000MHz during idle instead of 400/900, and 725/1000 during load.


specs: i7, windows 7, 750watt PSU, 10.7 driver, xfx 5850

Make a profile in CCC and then open it(from C:\Users\yourusername\AppData\Local\ATI\ACE) and post your Core and memory clock.

It's weird because in that profile, all my memory numbers are at 1000MHz, yet my memory still runs at 900MHz in GPU-Z

ie.
<Feature name="AutoTuneSupport" />
<Feature name="CoreClockTarget_0">
<Property name="Want_0" value="40000" />
<Property name="Want_1" value="55000" />
<Property name="Want_2" value="77500" />
</Feature>
<Feature name="MemoryClockTarget_0">
<Property name="Want_0" value="100000" />
<Property name="Want_1" value="100000" />
<Property name="Want_2" value="100000" />
</Feature>

It seems a bug with 10.7 drivers,because now that i checked mine,i idle at 400/900 whereas it should be 157/300,even changing it from the profiles didn't help! If it stays like this i revert back to 10.5, which showed correct 2D clocks.
EDIT,i decided to log-off after i made my changes, and when i logged in again, the clocks were correct(157/300).So make a new profile and edit it, here is how in case you don't know it
1_Open CCC and choose Overdrive tab,unlock the settings
2_Go top options,profile and choose profile manager.
3_In the composition tab,choose "The following settings" and in the "ATI Radeon HD 5800 series"make sure only ATI overdrive is checked.
Then enter a profile name,then save and close it(Do not activate).
4_Go to C:\Users\Your UserName\AppData\Local\ATI\ACE\Profiles (Its hidden so make sure you unlock hidden files and folders)
5_Open the profile with wordpad and do this edits:
<Feature name="CoreClockTarget_0">
<Property name="Want_0" value="15700" />

<Feature name="MemoryClockTarget_0">
<Property name="Want_0" value="30000" />


Save the changes and close.

6_Open CCC,in options tab go to profiles,profile manager and choose the profile that you saved before and then click on Activate and close.

7_Reboot and it should report 157/300 now as your 2d clocks.

same here, reverted back to the 10.4's which are the most stable on my end. This jumping back and forth between drivers is driving me nuts.

Well 10.4 wasn't good for me,(had 2D problems),10.5 was excellent,10.6 still gave me 2D problems so i kept 10.5 till now.
10.7 has been good so far, haven't had any 2D problems yet.

Hmm, no luck.

I'm using two monitors, so my default idle should be 400-1000 instead of 157/300 anyways.

I tried your suggestion and my idle is still 400-900, and refuses to go to full speed in GPU load applications.


It's weird, nowhere in my profile application does it list memory at 900MHz - it all states memory should be at 1000MHz (since I have two monitors). Yet my memory in GPUZ just shows up as 900MHz.

I once ran into this problem, after messing with the default profile. I ended up having to remove the drivers, do a complete clean sweap of ATI drivers, while in safe mode, then reinstalled in safe mode. After all that, it started to perform correctly again.

Right,i forgot you had 2 displays and your card should run @ 400/1000.
Well try installing older drivers like 10.6/10.5 or 10.4 and see if it helps(try to do a clean install of 10.7 first though)

I have the same problem on CCC from 10.4 to 10.7. The clock on GPU is 500Mhz and on memory - 600Mhz. Its in idle 2d mode, and my videocard (5850 asus) is heating up to the 60*C! Its not comforatble to let PC running 24/7 with this temps :pfff: 
I tried using profiles in CCC but this method doesnt work too. I spent 3 days trying to make my card runnig 157/300 re-installing different CCCs, but nothing helps :cry: 


p.s. My card was in service center for a month (had some problems with noisy cooler). Maybe some "evil genius" flashed my card with other BIOS... I know, that sounds silly, but i dont know now what prevents my videocard downclocking to 157/300 in idle mode. Maybe it is bios (or the wrong angle of the Moon :sarcastic:  )? I have BIOS Version 012.011.000.006 with BIOS Date 2009/09/25

I wouldn't be that concerned about 60C 24/7. Most the nvidia cards have been idling at 70C for years and they have not been having issues.

I tried to do a clean driver sweep/reinstall in safe mode...no luck. I guess I'll try older drivers next

I reverted back 10.5 because i had problems with 10.7,i hope 10.8 will be better and will get rid of this 2D clock issue.

Ok, I found the problem. Apparently firefox's plugin-container.exe causes my GPU to downclock to 400/900 even during gaming. Turning it off solves the problem...weird.

The root problem is the Adobe Flash plugin... grrrrr

Yep, I am using 3.6.8

Apparently the problem is when I have any video, quick time, silverlight or adobe programs open in firefox. It screen flashes and causes my card to be at a constan t 400/900.

Shutting down the application fixes the issue.

hmm,never had issues with FF but something similar happened to me.When i sometimes open Photoshop my VGA goes to 400/900,and doesn't come back to 157/300 even if i quit PS,i have to log-off/reset and it goes back to normal.
