6970 Powerconnector problem - Page 2

post #11 of 42
Thread Starter 
Received my new PSU today. Installed without any problems and did a fresh install of windows 7 home 64-bit. Updated motherboard BIOS and using all latest drivers. (ATI 11.9)
Still the same.. But I think I know the problems. Guess there's something wrong with the sensor. In Furmark the temps rise quickly to 100+ C.
Then when I stop Furmark the temps lower quickly to 50-60 C.
That doesn't sound like it's overheating or such. Also the card cooler isn't getting hot.
What should I do? Just RMA it or is there something else to try / test?
Would testing the card in the PCI-e x8 slot work?
Where on the card do I find the sensor? Really hope this is fixable.
First the problem with the 6950 and now this. Will it ever stop? Please help!

I am sorry, but I tried to tell you that getting a new PSU wasn't necessary.

Anyway, at this point I would RMA the 6970 because I think you're right about the sensor being faulty.

Or, you can just ignore the temps.

Well if I could I would ignore it but the fans just go berserk +40-50%.
Also while playing a game like Rift the GPU usage goes 100&.

Oh that's right, the fans go nuts too. I think that if this were happening to me, then I would probably RMA it (over the phone, using the word "defective").

..could be a warped chip..not making good contact with the heatsink..i'd rma it.that's my suggestion for you..if it was me..i'd check out what's under the hood..sand the ihs down.with a small,square piece of glass.reseat the cooler..bios flash w/fan fix..etc..

Open GPU-Z under the sensor tab, what are the temp readings for core, #1, #2, #3 and Vregs?

Edit:

That's a good sign of serious throttling.

So,

I've opened up GPU-Z while doing Furmark.
Furmark readings say 100+°C (104max. I guess that's when the videocard shuts itself down)

GPU-Z readings at that moment were:

Core 1: 54°C max
Core 2: 48°C max
Core 3: 49,5°C max

So something should be wrong with the sensor I guess..
Is there any way to fix this by myself without sending the card back?

I believe those are the idle temperature readings. What you need to check is the fullload temperatures. There are 4 temps in the GPU die, Core, #1, #2 & #3. If one of those temps is hitting 90-100°C, the core/memory and voltage will downclock to prevent damage to the card.

When one of the temps is hitting +100°C, you will see stuttering, graphical glitches and texture flickerings. These are the signs of throttling, overheat and memory/clock instability.

This is an easy fix, re-apply thermal paste, MX-3/MX-4 is great paste. Get some extra 0.5mm thermal pads in case you need it. Get the EK 0.5mm pads from www.frozenCPU.com.

Check with Technical Support you will not void the warranty by removing stock cooler. I never asked them, I just do it. But that's me.

Ok, let Furmark run for 5 minutes (long enough?) Settings: 1920x1080, Extreme burn-in & 4x AA..

These should be the 4 highest temps in GPU-Z:

GPU temperature: 74.0°C
GPU Temp #1: 74,5°C
GPU Temp #2: 71,0°C
GPU Temp #3: 69,0°C

Are the temps from GPU-Z to be trusted?
Temperature readings from MSI Afterburner, ATI Catalyst & Furmark itself reach 90°-100°C after 4-5 seconds and the fans go berserk.

Didn't have a single stutter, artifact nor glitch..

You have two conflicting readings. Make sure you select to show MAX, not current or lowest in GPU-Z. You have to find out the actual fullload temperatures, not after you close Furmark, it won't show you the temps in the past, unless you select show MAX.

Nevermind, just re-apply the paste and try again.
