AMD R9 280x hitting thermal limit at 70 degrees

[rajivrkr]

My Gigabyte Windforce R9 280x card will for some reason hit its thermal limit at 70 degrees while under load. When it reaches the limit, it underclocks from 1100(stock out of the box OC) to 1000, and will not go above 70 degrees

 

• Windows 8.1 64 bit
• CM storm Trooper(to show i have good airflow)
• MSI Z77A-G45
• Intel i5 3570k (overclocked to 4.2 GHz, probably not the problem)
• 4x4GB Corsair Vengeance RAM stock (2 high profile, 2 low profile)
• Gigabyte Windforce R9 280x OC (1100MHz out of the box)
• Samsung 840 250 GB (windows disk)
• WD 2TB HDD Storage drive
• Antec 650W Earthwatts Platinum PSU

 

Shown above is a benchmark done with MSI kombustor and GPUz to check the temps and clock speeds.

 

Previous to this, i had a Sapphire Dual-x R9 280x which also had a Throttling issue so i sent it back under warrenty and Sapphire sent me back this Gigabyte model. The issues before was that it would underclock from 1020MHz to 870MHz whenever it felt a bit of continued stress. Now this "new" card has a slightly different issue where it gets under laod and goes down to 1000MHz at 70 degrees.

 

Does anyone know where the problem lies? If it is my system or my MOBO or even the "new" card they sent me?

pretty odd. I had the Sapphire Dual-x R9 280x and it would get up to 80 degrees without throttling like that... I don't think I even ever saw it drop below its boost clock when gaming. fans would get pretty loud though.

You might need to re apply the thermal paste but I dont really know thats kinda odd B)

POWERTUNE- A DRIVER DEFAULT of using less than 100% capabilities from your card under load.

Thanks AMD /sarcasm

Available in the CCC or Msi/others

Power limit at 0% is kind of like 80% tdp allowance.

Use +20-50 and it won't declock.

This does not void warranty. Its Amd powertune a software feature.

Still set as 0 default but you have to use power limit as a positive value to reduce your clocks dropping. Normal stuff most ppl do not get taught in videos. Happens on all Amd cards I think currently sold... bar the super low end.

Always have it at +50 if wanting to maintain stock clocks and then overclocks.

Use the drop down in power target on msi afterburner for temp target, is it set to 70?

why did Sapphire send you a gigabyte model

Use the drop down in power target on msi afterburner for temp target, is it set to 70?

Power is a slider. And on AMD cards is -50 to +50.

OP should have +20 or higher to not declock.

thanks for all the help guys. 

since i am not at home, i will have to wait till i get home to make any of these changes, but i will respond when i have done so and tell you if increasing the power limit works

 

cheers

nvidia has this same thing, but the limit is at 80 degrees, in the EVGA precision X has a temp target, you can use that and change it to whatever limit you want
