ASUS MATRIX Platinum 7970 overheating

Hello everyone
I have recently purchased ASUS MATRIX Platinum 7970 at a decent price and was hoping to put it to use.
the card however is overheating. temperatures got over 85 degrees, fans start to spin like a jet engine, artefacts come up on screen and everything crashes.
Started with driver crash but now the application crashes and goes back to windows.
been running heaven bench and some red spots started coming up on screen before it crashes at 86 degrees celcius.

Added new thermal paste and no difference, cleaned and dusted but no difference.
Tested another card on it and everything is fine.

running on PSU corsair GS700 with i7 4770 and Maximus VII mobo.

took the back plate off but not noticed anything unusual.

any tips?
 
It maybe be caused by a defect in the power delivery sub system, if one of chocks or vrms are faulty the power going to the GPU won't be clean. No amount of new thermal paste, dust removal or reseating the HSF will reduce your temps enough to compensate.
 
Thanks for your reply

the person who sold it to me said it was all working fine before sending. Max temps were reaching 70 at standard fan profile. Could something happen during transit?

Is there anything I can do
 
You say you have replaced the TIM - it is worth doing again, just to be absolutely sure. The reason I say that is previously when I was selling my 780Ti's that had waterblocks fitted I had to re-fit the original coolers. When I did so and tested, 1 of cards was fine temps wise, but other card was heating up far too quickly and getting towards 90 degrees very quickly. I had to re-do the TIM a couple of times. I had clearly used too little or too much. I always put it in an X pattern across the core, but what you have to remember is that unlike CPU's a GPU is a bare die - that means that every single MM. of the dies surface needs TIM or you will potentially have a hot spot where heat is unable to be dissipated to the cold plate surface.

I'm not sure if this will help but try running it with case door off. Do you have any additional cards under it that might be effecting airflow?

I always use a Gelid Spreader to get an even covering.

I don't like the various methods of applying paste like using an X or a pea shape as there is no guarantee of getting an even coating or even using the right amount of paste.

The Matrix Platinum is not a good HD7970 either as it under performs clock for clock against nearly all other 7970s.

They are also notorious for producing a lot of heat in badly ventilated cases.

I used to own 3 of them.:eek:

Yeah that is probably method I will be using from now on Kaap tbh. I always used an X pattern as that was what EK recommends in their documentation and had always worked fine, but seeing the results with that 780Ti kinda showed me that is perhaps wasn't always the best.

Yup my mate had one. It overheated even at stock and had artifacts because of it.
 
Thank you all for the replies. I have purchased the spreader and will try with new paste that came with it.
Case was open during tests. It is the thermal take core v21 so good ventilation and airflow. There is nothing obstructing an airflow either side.
Going to try one more time with the spreader tonight and will post the results.
 
I know it's only anecdotal and not much help but I owned a 7970 Matrix Platinum for a good 2 years and never had any issue with it at all.

Hopefully a good re-spread of the paste will help yours out.
 
Hi All
Just an update to close the topic. With a good spread I have managed to drop it down to 77 in Unigine Heaven with max HD settings and it didn't crash.
however I have noticed that under 16.10.1 drivers from October - the textures are all over the place at some parts of the benchmark, only doping down to 16.9.2 is fixing the problem. Not sure if it soley to do with the driver or has anything to do with the overheating issues I had.
I think I can also forget about any type of overclock with temperatures reaching 77 degrees at factory clock.


Nevertheless I learned few things:
- always use a spreader when applying thermal to the GPU chip :)
- AMD drivers and cards can be a pain. Saying that I owned a Gigabyte 7970 and never had these type of issues.
 
Congrats on getting a better result. I would say you have little reason to upgrade from 16.9.2 if it works!
