Configuring 2D Clocks (Asus HD7850-DC-1GD5)

7 posts in this topic

Recommended Posts



I have an hd 7850 video card and it causes horizantal flickering when used with dvi to vga converter. I read somewhere that it's caused by conflicting 2d and 3d clocks, so with windows, I'm able to fix this problem by setting 2d clocks to at least 500 mhz. (with ubuntu the problem doesn't exist untill I install "fglrx" drivers)


is there a way to set my 2d clock to 500 mhz using os x?

yeah but it can't change 2d clocks. I kind of fixed the problem by using a hdmi to vga converter. the quality should be lower but it isn't really noticeable.


I used vbe for overclocking but it doesn't seem to work with os x. With windows I can play WoW with 50-60 fps with ultra settings and 8x multisampling but with os x i can hardly play it around 30-50 fps with medium-high settings and 1x multi-sampling

thanks! :)


for people with the same problem, I just copy pasted all of the codes else rampage wrote and I used 6819 as the device id for asus hd7850 1gb.


is there any program that can monitor my gpus temperature? I couldn't find anything


I was wrong. It didn't really do anything. When my pc booted up without a problem, I assumed it worked but the fps for recent games is still low


maybe it's not working fully because I have an amd processor?
