XFX RADEON HD 5850 Black running HOT!

Fahim · Dec 5, 2009

Hi everyone,

Basically, I was monitoring temp. between two RADEON 5850 that I have:

SAPPHIRE RADEON HD 5850 1GB (725,4000)
XFX RADEON HD 5850 Black Edition 1GB (765, 4500)

And the SAPPHIRE card stays at 42-46C idle, varying between these temperatures, but the XFX model is idling at minimum 50C, varying between 50-54C. Both card idles at 157MHz Core and 300MHz Memory. Both have reference coolers with different stickers on them.

I have both card's BIOS saved, and I was running two instances of RBE loaded with two bios, and the fan settings look exactly same on both cards, only the clock area is a bit confusing.

But since both cards are running at same idle frequency, temp. shouldn't differ, unless the thermal paste is not making proper contact with the GPU surface and the heatsink surface. Would it void the XFX warranty if I change the thermal paster or flash a modified bios?

I was wondering if anyone can have a look at the bioses and tell me whether there is a difference which might be triggering the higher idle temps. of XFX card.

Thank you for your kind help.

Show a screenshot of GPU-Z's temp/voltage tab. What does it say for the value marked VDDC when the cards are idle? (Usually at the bottom)

Many things can make your XFX card idle higher than the other 5850.

Heat from the other GPU.
Lack of direct airflow.
Higher clocks.

You put all these together and I think you have found why your card is idle at the higher temperature.

So long as your load temps are acceptable its nothing to worry about. :toast:

Hi,

I ran the card seperately, so they are not affecting each other.

My case is Antec 1200, with 3 x 120mm at front, 2 x 120mm at the back and 1 x 200mm on top. CPU is cooled by Zalman CNPS9900NT. So airflow is not a problem, its the same airflow for the other card as well.

Higher clocks when you go to 3D, but in 2D, both card runs at 157 core, 300 mem.

Are you having other issues? If not, don't worry about it. Very few cards will have the same temps...it's the nature of silicon.

Thanks erocker, That could be the source of heat. just checked the VDDC of both cards, and the SAPPHIRE got a lower value. The screenshots are below:

XFX HD 5850

SAP HD 5850

The first time i put the XFX in my pc, i did run msi afterburner to put the fan to 100% just for couple seconds to hear the noise (very noisy), then when I clicked on the reset button, i remember that the voltage slider on top of core speed went down as well as the fan slider. Then I went somewhere and when I came back, the screen was black and the gpu fan was running at full speed. I reset the pc, everything came back ok, so I uninstalled and then re-installed the catalyst to make sure msi afterburner settings gets erased. After that no problem at all. Maybe this incident will give you an idea of any voltage settings that might be different in the bios, and msi afterburner couldn't detect or something.

Anyway, why this card needs more voltage to run on same idle clocks as sapphire with lower voltage?

Could you please have a look at the bioses for me? I checked them with RBE, and clock table is different on both cards. Thank you very much for your help indeed. I really appreciate it.

Can you confirm 1.65v? That's not right... :confused:

Fahim · Dec 5, 2009

Thats what the screenshot says....

is that a problem with the card???

CrackerJack · Dec 5, 2009

WOW 1.65v yeah that's high

If that's the top card, you can assume some of temp difference would because the top card drawing alot of heat off the bottom card. But yeah that volt is really high or some bad reading.

edit: it must be a bad reading, your bios looks fine from what i see... and wth is with your amp. your sapphire is only 3.5 and xfx is 12.2 :wtf:

overclocking101 · Dec 5, 2009

um yep that voltage is incorrect it is enough to kill a 40nm pu thats not being xtreme cooled. im thinking something is wrong with the xfx card. it will not void the warranty if you change the thermal past with XFX BUT if you mod the bios it will for sure try the thermal paste if its still messing up then rma it man you paid a lot for that gpu and should not have to settle for a messed up card. just my 2 cents

I don't see anything weird here. Temperatures are normal for idle (even HD4870 runs 15°C higher in idle with aftermarket factory cooler). And since you have 2 cards inside, you cannot expect both to act exactly the same. There is simply spacing involved, air flow, thermodynamics.
The card in upper PCIe slot will never have the same temperature as the one below it.

Swap them around and observe the temperature again. If the patttern is similar when they are exchanged in slots, you're seeing exactly what i said.

Fahim · Dec 5, 2009

I just tried someting....and it is even weird now...

when i posted the GPU-Z, just after that ran furmark stability test with extreme burning mode, and GPU-Z was in background. The test temp. went to 92C with max current of 144W...

I just restarted the pc and repeat the same thing, and the temp was 82C with a max current of 61W...

FPS was same on both occasions....and also GPU-Z is showing a completely different info now...

Don't know whats happening.... :confused:

cadaveca · Dec 5, 2009

12.2a correlates with 1.65v. It might just be running that voltage, which scares me... Please verify with everest, or something...I'd not run a single bench, game, or change thermal paste if that's the case.

Simply send to XFX for rpelacement. They need to re-flash it with good bios if 1.65v is correct.

EDIT: we cross-posted. Seems maybe software error there? something odd is going on.

I am running one cards at a time for testing purposes...

Everest and GPU-Z screenshot...

cadaveca · Dec 5, 2009

Looks fine now. SHall we say software, and cross your fingers, and hope it does not happen again? Stay away from afterburner?

:laugh:

Fahim · Dec 5, 2009

I just ran furmark again with gpu-z background. I ran furmark in window mode this time to monitor gpu-z. furmark was showing 56-60w consumption as long as it was below 80C. As soon as it reached 80C, current consumption shoot up to 140W and gpu-z was showing 1.65v again.

cadaveca · Dec 5, 2009

Dude...STOP DOING THAT!!!!

:laugh:

Do you have the game, GRiD?

Damn, XFX :nutkick:

WTF!!!

EDIT: seriously, don't do that. You might kill the card. For reals, yo! :laugh:

I'm jumping up and down to see the card still alive though, TBH. :nutkick:

to everyone saying 45nm can't take 1.6v+, if that there card survives. :laugh:

And now that I think about it, you are not the first showing 1.65v. :laugh:

Just found something here...

http://forums.extremeoverclocking.com/showthread.php?t=331964

sounds like GPU-Z issue, let me check and verify....will post soon...

cadaveca · Dec 5, 2009

So, uh, use everest for a while, see what's up, if true.

EDIT: This is a very nice bug for overclocking under LN2. Very nice indeed. Please verify that gpu-z is the cause.

Could just be furmark that is the problem though. It uses so much gpu, hardware OCP/OTP may fails to get proper reading, causing the boost. 5xxx throttle is hardware, not software as previously.

Fahim · Dec 5, 2009

Looks like GPU-Z is to blame here.....

FurMark with MSI Afterburner and Everest.....

FurMark with MSI Afterburner and Everest.....and GPU-Z

Looks like GPU-Z does have a problem. Somehow its not only reading values, but also make every other monitoring software thinks what GPU-Z is detecting is right....

I think that solves my problem of temp. issues....was looking for something....now found something else...

GPU-Z is the problem, verified.

That is the reason of using FurMark, if a card stands the stress of FurMark, that means it should stand almost every other test...
