AMD R9 280x CROSSFIRE ISSUES WITH GTA V

aaron3238 · Oct 17, 2015

I can't seem to get gta 5 to use my second graphics card on gta. I have catalyst 15.10 beta. It works in other games.
Also, no gta profile shows up in ccc.
I have two monitors but I only play on one.

SPECS
8320@4.2
2x Asus r9 280x
16gb ram

Is there some kind of tool you can use in the ccc for crossfire to make sure you are using both cards or it tells you.

Geek Jed :

I open two instances of gpu z, the second gpu doesnt clock up to its highest speed and doesnt have any utilization.

Did you try restarting the PC, see if thats it.

Geek Jed :

Believe me I have

Is the other card working at all?

Yes it works in other games.

some games do not support having gpus in sli or crossfire, thats why its recommended to get a single strong chip instead of 2 weaker chips, i run into this all the time with my crossfire config

cdabc123 :

But other people seem to have the same setup working?

Geek Jed · Oct 18, 2015

aaron3238 :

Thier crossfire works with the same game?

aaron3238 · Oct 18, 2015

Geek Jed :

Yeah plenty of people have crossfire working with the game. Some might have stuttering issues, but mine wont use the second gpu at all.

Geek Jed · Oct 18, 2015

What CPU do you have?
Oh I see it.

aaron3238 · Oct 18, 2015

Geek Jed :

In the original post it says I have an 8320 @4.2

Geek Jed · Oct 18, 2015

Ok first do a complete uninstall of the drivers then reinstall.

aaron3238 · Oct 18, 2015

Geek Jed :

I have twice and ive tried 15.7 and 15.10 beta

Geek Jed · Oct 18, 2015

Then go to the registry and disable Ulps:

[HKEY_LOCAL_MACHINE\\SYSTEM\\ControlSet001\\Control \\Cl ass\\{4D36E968-E325-11CE-BFC1-08002BE10318}]

and change "EnableUlps" to 0 under the 0

I got this off another forum, see if it helps.
