R9 390 8GB Video Card

[tilted2]

This is my setup :
CPU: Intel - Core i5-4460 3.2GHz Quad-Core Processor
Motherboard: ASRock - H97 Anniversary ATX LGA1150 Motherboard
Memory: G.Skill - Ripjaws X Series 8GB (2 x 4GB) DDR3-1600 Memory
Storage: Samsung - 850 EVO-Series 250GB 2.5" Solid State Drive
Storage: Western Digital - Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive
Video Card: MSI - Radeon R9 390 8GB Video Card
Power Supply: EVGA - 750W 80+ Bronze Certified Semi-Modular ATX Power Supply

My video card is going at 94 C which is kinda high. How can I lower the temp? I tried afterburner but it doesn’t seem to work. How can I lower it and start mining for many hours a day?

Increase fan speeds, undervolt, open up your computer case for better ventilation.

If it still overheats, then check make sure fans are actually spinning.

How can I do all that? Any link to help me ?

Crimson or catalyst software, depends which one you installed as drivers for your graphic card, simply right click on the desktop and it's the first line of text with an amd icon in your drop down menu...
set fans to manual speed and undervolt your cards to your liking, I'm keeping my 390's at power limit -15~20% at about 63-65C at worst...

Good luck!

Any suggestions? Going at 88C seems high. Is it?

1) better case cooling

2) 1100/1250

3) trixx to downvolt more than -100mV

What do you mean with point #2?

Can I damage the card by lowering the volt like that?

Are the fans actually spinning? On the GPU. Are they spinning fast?


No you can't damage GPU by undervolt, worse case is you freeze your system.

- what is your environment temperature ?
- are the fans in the front intake fans (blowing fresh air IN the case) ?
- is the fan in the back an outtake fan (taking hot air out of the case) ?

I got a R9 390 in a gaming machine which never got over 79° C in mining-mode at 30° C environment (not mining with this any more due to high power costs).

Yea they are. I mean Idk if theres a program that will let me control the speed of the fans (not the GPUs) but they are spining. Also when I am mining I can hear the fans (louder than usual).

I guess i'll try lowering the voltage, that's what got me from 94 to 88C

Temp in room is 25 C atm
Yes the way they are setup, they are intakes and the fan in the back is an outtake. Amazing that you had 79C. I can't wait to figure out what the problem is....

Core 1100 (overclock) memory 1250 (downclock).

Afterburner - properties - fan, set a custom curve that works for you.

Afterburner lets you downvolt only -100mV, trixx does -200mV.

For a test run, set clocks to 1100/1250, volts to -100mV and fan to 100%. No, you cannot damage the card.

Dude you are a genius (look at pic)! Any way to be more efficient? Omg i might consider buying more damn... Does this mean I can mine 24/7 now?
