ditchwater Posted January 10, 2007 Share Posted January 10, 2007 I've got Vista Ultimate RTM working just fine on a mac pro with 3 gigs of RAM. But oddly enough Vista reports I have only 2 gigs of RAM. It's not killing me, but I am curious: is there some sort of memory limit on Mac Vista machines, or do I need to install a driver for one of the four unknown devices that show up in Device Manager? (The Intel Memory Controller Hub appears to be installed OK, under System Devices.) thanks ditch Link to comment https://www.insanelymac.com/forum/topic/38202-memory-reporting-incorrectly/ Share on other sites More sharing options...
curlyboy Posted January 11, 2007 Share Posted January 11, 2007 Hi I dont know whats happening with your memory but you should try and install unknown devices tho Link to comment https://www.insanelymac.com/forum/topic/38202-memory-reporting-incorrectly/#findComment-273323 Share on other sites More sharing options...
alovhaug Posted January 11, 2007 Share Posted January 11, 2007 I have the same set-up and the same problem - 3 GB of RAM but only 2 available in Vista. (All RAM is seen correctly in OS X). I am only showing two unknown devices, however. One other minor problem I have is that my sound card seems to be unpowered or something. Again, it works fine under OS X. Under Vista, it works, but it is very, very quiet, and even with the sound maxed on my speakers I can barely hear it. Weird, huh? I am hoping that these are driver issues which will be addressed as Vista is released and more people attempt this configuration. but any thoughts or suggestions would be greatly appreciated (I miss my RAM!)

Tiburon Posted January 13, 2007 Share Posted January 13, 2007 try installing the 64bit version. Link to comment https://www.insanelymac.com/forum/topic/38202-memory-reporting-incorrectly/#findComment-274645 Share on other sites More sharing options...
ditchwater Posted January 14, 2007 Author Share Posted January 14, 2007 Thanks. I fixed two of the unknown devices, but I still have one unknown device and the "base system device" showing up as problems in device manager. Any help with that appreciated. But anyway the issue remains: a gig of memory is missing from Vista, compared to OS X. This might explain why I couldn't get the graphics working properly on Vista when the Mac Pro had only 1 gig of RAM: maybe Vista thought there was even less than 1 gig, and it choked. Now that I have 3 gig on the Mac, Vista is happy enough thinking there is 2 gig. I think I will just wait till Jan 30, to see if Apple updates its Bootcamp drivers. cheers john Link to comment https://www.insanelymac.com/forum/topic/38202-memory-reporting-incorrectly/#findComment-275424 Share on other sites More sharing options...
alovhaug Posted January 14, 2007 Share Posted January 14, 2007 Yep - that's exactly what I have: errors on "Base System Device" and "Unknown Device". I suspect that the 64bit version might solve things as Tiburon suggests, but I am going to wait for a while too and see if support improves. Is your sound okay? I wonder what the deal is with mine. As I mentioned previous, it works it is just very quiet (despite setting various Vista volumn settings to maximum). It works at normal levels in OS X, so I know it isn't a hardware problem. But no big deal... Link to comment https://www.insanelymac.com/forum/topic/38202-memory-reporting-incorrectly/#findComment-275492 Share on other sites More sharing options...
ditchwater Posted January 14, 2007 Author Share Posted January 14, 2007 You should be able to see up to 4 gigs of memory on a 32-bit operating system, though: 2^32 = 4,294,967,296. Why would there be a 2 gig limit on 32-bit Bootcamp Vista? Is there such a limit on Bootcamp XP? (I haven't tried the sound, since I use a USB headset, but I will give it a burl later today and get back to you.) cheers ditch Link to comment https://www.insanelymac.com/forum/topic/38202-memory-reporting-incorrectly/#findComment-275497 Share on other sites More sharing options...
alovhaug Posted January 15, 2007 Share Posted January 15, 2007 I agree that we should be able to see more than 2 GB of memory in 32 bit versions. In my research I found some info that suggested this was a reported problem in one of the Vista release candidates, but that it seemed to be fixed in the last release candidate before RTM. But then perhaps there was some kind of problem with the added memory and they removed support before the final version. That would suck. (That is just speculation on my part...but it does make me wonder...) If you have a chance to check the sound thing, it would be greatly appreciated. I've been looking at it some more, and I haven't really come up with anything. Everything looks in order. It is universally quiet regardless of the application. I've been watching audio play in the "Volume Mixer", and the speakers and the applications are all set to the maximum volume possible, but the audio that is playing maxes out at around 1/2 of that, and only if I set the application to the highest audio volume (and it rarely gets there, either). It doesn't matter what application is producing the audio, either. Bizzarre.
