perroboy Posted January 5, 2012 Share Posted January 5, 2012 Bear with me, because I'm gonna talk first about a dual-installation thang before coming to the point. I have a working Lion installation on a z68x-ud3h-b3 and decided I needed Windows. So, I popped in a new SSD, unplugged all the Mac drives and installed Win 7 64b pro. Hurrah. Plugged the Mac drives back in, Chimera immediately recognized the new system and it boots successfully. However, it was taking 20 + min. to get to the login screen on a Vertex 2. Long story short, I eventually hit on something and it fixed the boot problem entirely. The suggestion was to reduce the memory allocated to the onboard graphics card to 64MB. I have been running Lion with the onboard graphics maxed out at 482MB which shows up as 512 in system profiler. The Windows forums say that this is only for the initial boot phase, and that Win 7 makes us of the graphics memory as needed when it boots. My question is, do I have to set the memory high in the bios for Lion or does it manage memory in the same way that Win 7 does (perhaps explaining the 512MB of memory displayed in system profiler) ? If not, then I guess I'll have to swith between bios settings everytime I want to dual-boot? pato Link to comment https://www.insanelymac.com/forum/topic/274280-hd-3000-graphics-memory-allocation/ Share on other sites More sharing options...
