crossfire rx 580

[beetlespin79]

I am trying to test tom clancys the division using two powercolor rx 580s in crossfire! My problem is severe stuttering!

 

I have seen micro stuttering, but this is far worse! This is a continuous stuttering so bad that actual FPS drops by almost 70% on medium settetings!

 

And its not just the game, firestrike, unigine's heaven and superposition, GTA V, and any tomb raider verion! All suffer from this problem!

 

specs bellow

intel 4770k

16gb ram

crucial 512gb SSD

2 powercolor red devil rx 580

antec 1200 watt PSU

ASRock z87 extreme4

most recent amd drivers

Can you download GPU-Z and confirm it shows them in Crossfire?

 

Also what monitor, refresh rate, vsync on?  Freesync?

Reinstall the drivers. See if that helps

 

Or go back a driver revision

Also - did you run through Radeon control panel to launch the game with the correct Crossfire profile?

i have reinstalled the drivers, but i have not rolled back to an earlier version and i havent run the game through the amd "control panel", although i run firestrike through amd's contol panel with the same severe stuttering! 

 

so, i will try the two suggestions first! As a little extra info, with crossfire disabled, gpu-z shows both card as identical, the the memory vendor the only difference!

 

the odd thing is, when crossfire is enabled, gpu-z shows the second rx 580 very different! it shows the amount of memory with autodetect as the vendor and the memory bus as 32 bit and the core clock at 700mhz and the rest of the info is greyed out

 

i can verify this b/c when i open msi afterburner, the core clock is 700mhz instead if 1411mhz, but when crossfire is disabled both cards show the correct speed in afterburner, just only one being used!

1.) So GPU-Z is showing the first card in Crossfire at the bottom of the screen? 

2.) ULPS - I remember having issues with this at one time and having to disable this, its something about power delivery to the cards.

3.) You have to mate Crossfire Profiles under the GAMING tab of the Radeon software with the games you have and launch only from there to get the Crossfire

 

When not under load or not needed (or there is no profile) your second card wont be used.

ah, yes! well there could be my problem! im launching games right off of the icon on my desktop!!

 

my monitor is an old Asus! It does not have freesyn or g-sync as an option and vsync setting is off!

[beetlespin79]

OMG, I have found a problem and should be kicked in the a$$ for it! So, my pc has a 4770k right? Come to find out, when you fail to look or remember replacing my i7 with a celeron 1850, this usually and IS the problem!

 

i had forgot that i removed my i7 and put it in Asus motherboard, and put a celeron 1850 in this (ASRock) board! no wonder there was stuttering or really lack there of!

 

this is a HUGE bottleneck with the 2 cores running 100% usage constantly, even with no action on the screen, and the GPUs never reaching 30% usage!

 

it is AMAZING, what replacing a celeron with a core i3 4370 will do!
