The tests were performed in a controlled air conditioned room with temperatures maintained at a constant 25c – a comfortable environment for the majority of people reading this.
Idle temperatures were measured after sitting at the desktop for 30 minutes. Load measurements were acquired by playing Crysis Warhead for 30 minutes and measuring the peak temperature. We also have included Furmark results, recording maximum temperatures throughout a 30 minute stress test. All fan settings were left on automatic.
When we started Furmark the temperatures would rise at 104c after 30 seconds and cause the system to shut down. We removed the cooler and applied our own high grade thermal paste and assembled again, checking for adequate mounting pressure.
The results above are what we achieved with the card after applying new thermal paste. 99c under Furmark load and around 90c when gaming. These are not great results and we aren't sure if there is a problem with this particular board, we may have received a faulty sample. You can also see that the fan is spinning at 100% which explains why it was so loud with our acoustics testing on the previous page. VDDC current is showing an intake around 79A which seems high to us.
We chatted with Powercolor before going live, delaying the review for several days while they had time to investigate and they said that it was not common for these cards to run so hot. We would therefore assume that this particular sample is slightly faulty.
Nice looking cooler indeed. weird about the temps, that seems very high. the A on the furmark and GPUZ seem VERY high though, I wonder is the bios messed up?
They are making some great cards. bummer you got a dodgy sample. it happens. at least they arent cherry pickin them
Hey, can you pass over my details to powercolor? I have the same card and the same problem. I dont think its your specific sample, perhaps a faulty batch with too much voltage?
Score is too high, the card is faulty, you review what you are given. 6/10 max
Fumark is too much of a stress test now. its like prime. its useless nothing ever stresses out hardware this much. something like crysis is fine. all you need
This is why Sapphire get such a good name, because things like this just dont happen for them!
6870 isn’t a good seller for AMD. its one of their worst sellers. the lower end boards get them their gravy.
optix what do you mean? i think this deal about sapphire being perfect is stupid.
I have had sapphire cards fail before years ago. most of them are made in the same factories anyway by palit.
You scored it too high, even if it is a bad card, you needed to score it lower. Cant take powercolors word on it !
I found another review and theirs seems ok. I think this one might have a different bios with more voltage. the Amps look higher than even most OC’d models ive seen in furmark.
