Hey guys - is there anyway to change the VRAM on the ati x1600 on my 20" iMac - i would prefer it to be higher.

Can you also tell me how i find out how much vram is currently assigned - i think it is 128mb which is really low especially considering the size of display!

Apple Logo > About this Mac > More Info > Graphics/Displays should tell you how much Vram you have.

Follow the "path" that "MacDude121" mentioned. Your iMac probably has 128meg of vram...but special configurations (custom ordered) could have 256meg.

Ahh - yeah it is 128mb only.

Is there no way to turn this up then?? Most intel integrated cards can grab vram off the normal RAM thats all.

Key word integrated and they are also limited but no on every Mac but the Mac
Pro you are stuck with the video card and vram you bought.
