help rx480 crossfire problems

[wethenation1]

ok so my problem is when in crossfire mode when ever i start a game like black ops 3 right away you can hear the card rampping up as if theres a heavy load on them and it gets so loud and bam screen goes black and computer bricks up. anyone have any clues?

the main problem is that you went with multi GPU (CF/SLI) instead of buying single card like GTX 1070/1080.
you may have faulty card: try to remove the second card and see how it works with each card as single one.
if above works, you might have problem with MB - check that single card can work in any slot. that will 90% eliminate the faulty MB.
of course it could be that your power supply is not able to hold the system - a minimum 650w good quality PSU is required assuming you are using some 100watt CPU.
and finally, it can be drivers issue. try to reinstall the drivers/windows whatever.
after you solve the above problem, you will still have following unsolvable issues: noisy system, stuttering in games, high input lag, crashes and micro freezes. not to mention that no all games will support CF.

There's nothing really wrong with multi GPU setups. Yes there are cases where they do not perform as well as a single card, but there are also other examples where SLI / CF perform nearly double the speed of the single card, matching higher end cards.

I suspect the problem is being caused by your power supply not having enough wattage to run your components. Testing with each GPU individually is a good place to start, to see if the problem is the power supply. And yes, you should plug both monitors into the single GPU.

Did you overclock the CPU/GPU before hand?

What you are hearing, is the result of a lack of power being able to be supplied to your cross fire setup of two RX 480 cars.

Just to check.

Post the brand of the power supply in the system, it`s total peak output in watts.
And also the total amp output of the 12v power rails of the PSU.

Electrical components draw power from a PSU.
Draw being the Key word.

multi GPU for gaming are only viable when there is no single card that can provide acceptable performance.
multi GPU has to many performance and stability issues to be seriously considered for serious gaming.

i tested both gpus separately and both work fine.

 

[wethenation1]

well the psu is seasonic 620w

try to reinstall the drivers.
uninstall with DDU, and do clean install.
otherwise the most probable is the PSU.

 

[wethenation1]

reinstalled the drivers i played longer then 5 min like half a game of cod but the fans were 100 percent the whole game but when it shuts off the fans just kept getting loouder and louder

I think you need a more powerful PSU, remember you have an unlocked CPU and probably Overclocked already.

i just found out my pc draws at least 576 watts and my psu is only doing 580 so yeah im going to get a new one before i blow up

Frame times and their variance are more important than avg frame rate.
it's pointless to have 200 FPS with stuttering/freezes. it can (and often does) make the game unplayable.
and of course higher input lag that inherently can't be solved on multi GPU. Today, there is no single monitor that can't be handled with single card. so CF/SLI is for those who are interested in FPS numbers more than in games or just uneducated crowd that has no idea what is high quality PC gaming.

RX 480 Crossfire, especially the GTR could use up to 500 watts under loadon Its own but those are stress testing numbers. I wouldn't say you're constantly using more than 550 watts for your system overall. As others mentioned, see if one RX 480 works fine or not.
