5850 GPU not downlocking?

So I'm currently using a friend's 5850. It's an XFX version, regular/non-OCed stock settings.

However, I checked in GPU-Z, and it always stays at 400MHz core, 1000MHz memory clock settings. It increases for games, but doesn't decrease when idle/on desktop.

I was looking through forums and 5850s usually idled around 150 core and 300 ish memory...

What is wrong with my current card?

Here is a pic of BIOS and GPUz:

Well maybe your friend has created a profile for it.
Go to this address
C:\Users\Your UserName\AppData(its a hidden file)\Local\ATI\ACE
And you have to see a file called "Profiles",open it with word pad and make sure its like this:
<Feature name="CoreClockTarget_0">
<Property name="Want_0" value="15700" />
<Property name="Want_1" value="55000" />
<Property name="Want_2" value="72500" />
</Feature>
<Feature name="MemoryClockTarget_0">
<Property name="Want_0" value="30000" />
<Property name="Want_1" value="100000" />
<Property name="Want_2" value="100000" />
The first line of both "CoreClock" and "MemoryClock" are the idle speeds(157/300)

yup that looks fine(mine was for a 5970 though)
Is catalyst control center reporting 400/1000 in 2D mode too ?

In CCC Overdrive, it says the current clocks are 400/1000...so ye, it says the same thing as GPU-Z



(btw OPEN-GL is enabled...if that means anything?)

Also, my old XFX 4850 would never (report at least) downclock in 2-D, however it still ran amazingly cool.

It says OPEN-GL enabled in GPU-Z (it has a check mark).

Yeh, the 5850 idles around 45-50'C (room temp of 77'F). I've seen posts of other people's 5850s idling around 30-40'C.

My main concern is why the memory doesn't downclock at all, and why my core doesn't downclock enough.

Yes the idle temps is around 30-40
Its strange really,can you test with other drivers too ?

I currently have the newest driver:
ATI Catalystâ„¢ 10.4 Suite for Windows 7 (64 bit)

I selected the options via the ATI website:
W7 64bit --> Radeon --> HD 5xxx Series PCIe


Should I try an older version?

Are you sure it isn't OpenCL?

Perhaps XFX changed the BIOS to improve 2-D performance?

Yep, I meant OpenCl. And it says the DirectCompute 5.0 is checked, if that means anything.

I think flashing another BIOS would solve my problem since other BIOSes seems to have more idle states, but that would invalidate my warranty... >_<

I don't think those (OCL and DC) have anything to do with it, just odd as OCL doesn't get checked on my 5850. I guess you have something else installed.

K, I'll try that tomorrow. Any recommendations?

And where can I find old drivers? I googled old drivers it but a bunch of them turned out to be unofficial user made ones.

Would Guru3d or techpowerup have the official older drivers?

Just google AMD 10.3 5850 drivers.

Mate, this is normal, you are using 2 monitors

When using 2 monitors , 400/1000 are correct rates to prevent monitors from flickering. Its same on nVidia cards so you have to sacrifice power to get your 2 monitors running :)

Yep. I googled this 2 monitor issue and you are correct...

I can't have my computer running at half GPU load all the time so I guess I'll have to manually set clock speeds...

Well, what I decided to do was overclock my XFX 5850 to 775/1100 from 725/1000.

This overclock caused the GPU to go back to its original underclocked state when idle (157/300) and not stay in constant moderate load at idle. Now my GPU idles at 33-34'C instead of 50'C.

My 2nd monitor now experiences the flickering problem.

The annoying flickering on my 2nd monitor is perhaps worth putting up with when I get an overclock + lower power consumption/heat overall???



EDIT: Nvm, I just watched a video and it flickers like every second...it's gonna give me spasms... >_<

How bad are the temps? 400 might not be that bad, and I don't think the ram runs all that hot.

^ Regular idle temps are around 30'C.

Dual monitor moderate load temps are around 50'C, so ~20'C increase by going from
157/300 to 400/1000.

For me,when i raised my 5970's clocks from 157/300 to 400/900,my temp raised by 10c(i was using one monitor anyway)
I hope ATI will do something about this though,so users can have the idle speed of 157/300 with 2 monitors

Yeah, something still isn't right. My measly 4650 runs at near the same clocks (165/250) and seems to have none of these issues.

What do you mean by Fix Maziar. Its not that its broken, its just that more power is needed to run the 2 monitors (more desktop area to work with). May be if you turn off the Aero it will be easier and wont flicker so much but still this is the reality

Do you think ATI made this purposely so you get hotter more power drawing card - NO. Its not a bug and it wont be fixed , saying it for the 10th time in the forums :)

I think the problem could be not just the 2 monitors, but something else. I have a XFX HD5850 connected to my vga monitor (dvi adaptor) and a LCD tv set, and i was running it with Windows XP Pro SP3 (x86). The stock clocks are always 400 and 1125, but when i tried to overclock or downclock to any value, the values go to 157 and 300, the flickering problem started, but the gpu temperature decreased about 20 degrees. Now i installed a fresh copy of Windows 7 Pro (x64) and the always still the same, except for the fact that when i try to overclock or downclock the gpu, the value that i set is the value that stays, so i can't downclock it under 400/565, which is a little ***, cause sometimes i would like to set my gpu in a idle state (like when the computer stays on just for downloading). I dont know why my XFX dont decreases anymore to idle state when i try to overclock it or downclock it (which is good, cause could be a bug), but for other hand i cant use something like msi afterburner to create profiles for 2D and 3D, cause my gpu stays always in stock clocks (excpet if a set 400/565, which are not enough for me).

Updating:
Just disabled the second monitor (tv set) and now i could drop clocks to 157/300 by setting any clock but the stock 765/1125 (that is visible as 400/1125, but i have too set 765 anyway).

Yeah, it's not about power. My 4870 could handle two monitors just fine and still downclock the core to its lowest values.

The problem is the 5x00 just doesn't downclock correctly with more than 1 monitor because it needs to keep the memory at a constant load-speed for some reason...

I have dual monitors and my 5850 downclocks just fine, problem is the only driver that will work (downclock in 2d mode) is the 10.4's. 10.5 and 10.6 won't downclock for me.
