5850 Overclocking unstable? by even 5 core clock?

post #1 of 5
Thread Starter 
So when I try OC my 5850 i get a massive screen flicker on my second monitor even going from 725-730mhz coreclock, I dont get flicker when using only one monitor though, why is this>?

Because it interferes with the 2D cloks for multi-monitor.

 

Solutions;

 

1. Edit the profile  http://www.techpowerup.com/forums/showthread.php?t=117633

 

2. Or create 2D and 3D profile using Afterburner.

okay so im only wanting to go for 775mhz core clock and 1125mhz memory clock(max that the control center will allow)

I found where you do 2d profile and 3d profile, what should my 2d be set at? stock? and my 3d at the OC?

Use MSI afterburner and update to the newest driver.

I get 840/1300 on stock voltage on my 5850.

Leave your 2D alone and only overclock your 3D.

The multi-monitor problem was supposed to be fixed in newer drivers, no? What driver are you using?
