Video Ram loss in Windows 7 64bit (bootcamp)

Hello Mac gurus.
I currently own the latest edition of IMac 21.5" 2.5Ghz Quad-core processor desktop. I had partitioned my HD with Snow Leopard and 32bit Windows 7. While running that, I showed the full 512mb Video Ram on my card. It even showed upwards of 1Gb whenever I did "tests" at canirunit.com.
I recently replaced the 32bit Win 7 with the 64bit version to increase Ram output, etc... However now whenever i run it through the same website it only shows 229mb of Video Memory. I also did the "dxdiag" on the start menu of Win 7 and got the same result.
After calling apple support they said to update the video card drivers, and run a hardware test. Did both (drivers on the win7 side not snow leopard). Hardware came back ok. 512mb as shown on my video card, however i still am only showing the 229mb available video memory when I run the same tests mentioned above. I am also noticing quite a bit more pop in and video lag/low resolutions when playing Arma 2. Graphical issues I did not notice before.
Any suggestions on how to correct this issue, if in fact I actually have one.
Thanks for your help.

Hi, I have same problem with my Sandisk 8 Gb Ultra. I've tried plenty driver but stil didn't work. Then I found this page: http://forums.sandisk.com/t5/All-SanDisk-USB-Flash-Drives/Sandisk-Cruzer-not-rec ognized-by-Windows-7/td-p/233208. They said Sandisk have problem with Windows 7, and you can try their method to make it works. I'm not yet trying it, but I've tried changing sd card with my other sdcard (micro sd actually, with adapter, branded V-GeN) and it works with original Apple broadcom sdcard driver (from bootcamp assistant). So the problem not with Apple or SD card reader, but with Sandisk and Windows 7. So, do above method, or change your sd card, or change your OS, til solution come up with this.
PS: There is other solution. Just open your sandisk card on Mac, then copy your file to Mac partition, then you can open it from Windows 7 (to modify, you have to copy it to Windows partition first). And vice versa.

Bootcamp Dedicated Video RAM

Hey guys,
I have a 2012 13'' inch macbook pro. This has the Intel HD 4000 graphics card. I have upgraded it to 16GB of RAM and and have windows 8.1 installed on a bootcamp partition.
Currently on my windows side it says that I only have 32mb of dedicated video ram. On the apple side it says I have 512mb. I would like to increase the dedicated video RAM on the windows side to fully use what my computer is capable of. Normally in a windows computer to change your video RAM amount you go into the BIOS section, but since this is on a mac it doesn't have one.
I have been through about a billion tech support calls so here is a list of the things I've tried.
What I've tried:
     1. Using Refind to access BIOS on this.
               -The new version doesn't seem to do much for windows as the only bootup option I am given is to bootup normally
     2. Force the intel HD graphics driver 15.33.30.64.3958 to download and install
               -Forcing it still doesn't have it run properly. I've contacted intell and they say their drivers don't always work on laptops
     3. Using parallels
              -Unfortunately parallels runs extremely slowly when you're trying to use 512 mb of dedicated video ram for some reason
Any help, or a direction to go in would be greatly appreciated.

You may not need to do all this. Please read http://www.intel.com/support/graphics/sb/CS-033984.htm .

Is it possible to use my ram as dedicated video ram on windows 8 bootcamp

i have a mid 2014 MacBook pro
8gb of ram
dual core i5
intel iris 5100 graphics
im using my mac for gaming and need some dedicated video ram, I saw other computers like asus or Toshiba that were able to boot into windows bios and change there ram as dedicated ram, bootcamp has no bios so im wondering if there any third party applications of something built into bootcamp that would allow me to change a setting like that.
thanks in advance

Windows video ram with bootcamp.

In bootcamp when I run windows 7 it tells me I have 188mb of video ram but in mac it tells me 512mb. Am I confused on something or is there a problem in Windows?
I have a macbook pro late 2011. Its a quad core, 16gb ram, and I have a AMD Radeon HD 6750.
I do not know that much about this topic so I might just be mixing things up.

The HD4000 graphics in your Mac has a tiny amount of dedicated memory (the 32 MB you're seeing) and borrows what it needs from your system RAM. That's where OS X reports its 384-512 MB. Games should still work fine, just set your resolution and in-game detail options accordingly. Most games should run OK at the MBP's native 1280x800 resolution at low to medium details.

Windows 7 No 4GB (32bit) and in 64bit BootCamp drivers do not work!!!

Hello. I have a MacBook 3,1 (late 2007 model) with 4GB RAM. Under Windows 7 32bit, only 2.96gb Ram is useable and the Boot Camp drivers run fine. How do I get Windows 7 to recognize the entire 4GB? I have used bcdedit /set pae ForeceEnable and that doesn't do anything, still 2.92gb useable not 4gb although W7 recognizes the 4Gb as available? How to enable to fully?
Second, 64bit Windows 7 recognzes the full 4gb but the Boot Camp drivers do not install at all! Hence, no mouse, sounce is crap/unusable, and the rest of the Apple devices are crap. I have downloaded BootCamp 2.1 update but in 64bit Vista, when I run BootCampx64.msi it sells me "Bot Camp x64 is not supported for this model." Hence, the 64bit drivers do not install DESPITE a 64bit OS.
I went to the Genius Bar but the guy was an oaf and didn't know anything helpful. Help please!?!!!
Help please.

Windows 7 is not fully supported as it is not released yet. You might be able to find some Windows Vista 64bit drivers for it but there is no guarantee that it will work.
You are incorrect! I am UPGRADING from Vista 32bit which supports 4GB of RAM with SP1. If you read my original post, you will see that I already tried the Vista 64bit drivers in Windows 7 64bit.
Windows 7 is downloadable from Microsoft and also supported already by Parallels v4 and the latest Fusion.
Hence, my original questions stand: How can I enable fully enable 4GB in Windows 7 32bit? Or, install, with Windows 7 64bit, install the correct Boot Camp drivers?
As I said, when brunning the Vista 64bit Boot Camp drivers in Windows 7 64bit, it says "Vista x64 Boot Camp not supported on this model."
Anyone have any suggestions?

your video card have 64MB video memory and can then "borrow" the slower system ram and use it for video memory

Video Ram using windows

hy everybody i've got a question.
I recently bought a brand new iMac (27' 3,4 i7 4GB Video Ram 8GB cpu ram 1TB fusion drive). I need to install a win programm which needs at least 3 GB of video ram.
i tried with parallels desktop 8 but it said i can only virtulize 1GB of video ram.
i wonder if anybody got my same problem, should i use boot camp or any other program?
i can't stand to wait a mac version of that program or any other program, i've got 4 gb of video ram and i want to use them!
thank u very much and sorry for my not perfect english!
Apple rulez!

From what I know, that game doesn't require 3 GB of VRAM, so you should be able to install it on your Mac with Boot Camp.
First, get a 64-bit Windows 7 and 8 version, and follow these steps to install Windows > http://manuals.info.apple.com/MANUALS/1000/MA1636/en_US/boot_camp_install-setup_ 10.8.pdf Then, install the game

Mac system freezes on startup, but Windows in Bootcamp still runs fine

A few days ago I tried to turn on my Macbook Pro (mid 2010 model, 15 inch) but it only gave me a black screen and triple beeps. Thanks to this forum I found out it was a RAM problem. So I took it to a local certified mac repair shop and they cleared the RAM issue, but after I entered user name and password on start up, the Mac OS just boots to the desktop and freezes. I can't open any files or folders or apps. Strangely, the Windows in Bootcamp works perfectly--I can open local files and those on the Macintosh disk. The person at the store suggested that it could be a logic board problem or hardware failure. I'm not really buying that since Bootcamp still works (and also I'm reluctant to spend $500). Anyone has any idea what the issue could be?

You COULD have the bad GPU found in some 15" mid-2010 MacBook Pros... you'd have to take your computer into an Apple Store or an AASP to find out.
Mid-2010 15" MacBook Pros - the bad NVIDIA GPU
If you're having frequent kernel panics with your 15" mid-2010, or intermittent screen problems, the problem is, more than likely, the faulty NVIDIA GPU found in a number of those machines.
Here's just a sample of a kernel panic log that points to the faulty NVIDIA card:
Kernel Extensions in backtrace (with dependencies):
         com.apple.GeForce(6.4.0)@0x82ac4000->0x82b7afff

            dependency: com.apple.iokit.IOGraphicsFamily(2.2.1)@0x8301b000
Here's the "official" Apple take on the issue - but the very real kernel panics need not be preceded by 'Intermittent black screen or loss of video'... in fact, you might not experience any video problems at all. Although video problems can certainly be a portent of things to come…
So what can you do? Print out a copy of your kernel panic and a copy of the Knowledge Base article and take them, along with your machine, to your local Apple Store or an Apple Authorized Service Provider. They should be more than willing to install a new logic board at no cost. I have no idea why this faulty GPU is making the headline here on the MacBook Pro forum so often now - could it be because Mountain Lion is just bringing the issue to a head more readily? I don't know - I only know that we're seeing more and more of these kernel panics of late.
Good luck,
Clinton

Dedicated Video RAM (64 MB?!?!?!)

Could someone explain me what dedicated Video RAM is, please? I have the better MBP 13'' with the Intel HD Graphics 4000. Behind that information it say "512". I thought that meant I'd have 512 MB VRAM! True?
If I check a game on canyourunit.com (I have Bootcamp Win 7 64 Bit) it always says my dedicated Video Ram would be too low. I would only have 64MB. According to that website I wouldn't even be able to play Age of Empires III, well I can play that game perfectly...
Can someone help me out?
Thanks! Passer

The video memory (Vram) on any Intel integrated graphics is dynamic meaning that the amount allocated is dependant on :
The amount of total memory installed in the machine ie 2Mb, 4Mb etc
The program being used and how graphically demanding it is.
Thus the machine will allocate anything from 64 Mb upto 768Mb, you as the user can not normally change this.
(This is the same for Windows machines with Intel graphics)

Allocating more video ram?

ive read the bootcamp only emulates an integrated video card which allows 64MB of video RAM. is this true? im trying to run a game that requires 128MB, my macbook pro is 256MB.
is it dueable?

VMs like Parallels may limit video, but Windows Vista maps VRAM to system memory and so rather than showing the video card only, shows much more, even with 64-bit and dedicated graphics (8600 GTS PCIe).
As graphics cards get bigger and games hit 2GB application space, games are hitting the 32-bit walls.

Can not reboot into OSX from Windows using Bootcamp assistant

I'm having a bit of a problem with rebooting into OSX from Windows on bootcamp. Clicking on the icon in the system tray produces a message that Windows can not find the OSX disk. Trying to open the Bootcamp preferences also generates an error. I have no problem getting back into OSX if I shut down Windows and restart the MacPro while holding down the option key. This is with a Windows 7 install on Bootcamp, but I had the same issue with a previous install of Win XP. I nuked and paved OSX and the WIndows disk between installs so my current problem is not carry over from the XP install.

My bad I should have been more clear. The problem is actually with a XP install via bootcamp, my Win 7 install is in VM Ware Fusion.
The XP install is on a second drive. Since you asked about this I'm assuming it may be the reason Im having problems.
The error is I get when trying to access bootcamp via the Windows control panel or by right clicking the sys tray icon is - "An error occured while trying to access the start up disk settings. You may not have privileges ...blah, blah, blah. I only created one account and I have enough privliges to change admin stuff in windows so I cant see privliges being the issue. I reassigned the OSX partition a new drive letter and rebooted windows but this didn't help.
The only drivers I installed, other then updating the video driver, are the bootcamp drivers
Sys tray icon - small diamond shapped icon in systray for accessing bootcamp functions.

After upgrading to mountain lion i keep getting an error message saying my startup disc is full. it shouldnt be full because there is barely anything on there and i was running windows with bootcamp prior to this with no issues

after upgrading to mountain lion i keep getting an error message saying my startup disc is full. it shouldnt be full because there is barely anything on there and i was running windows with bootcamp prior to this with no issues. my computer now freezes and programs close randomly. The usual command for opening windows with bootcamp doesnt work. once in restarted my computer after it froze and it rebooted in windows automatically. i really just want to know if there is a way to take the upgrade off my laptop because it is very annoying.

Hi Memalyn
Essentially, the bare issue is that you have a 500GB hard drive with only 10GB free. That is not sufficient to run the system properly. The two options you have are to move/remove files to another location, or to install a larger hard drive (eg 2TB). Drive space has nothing to do with SMC firmware, and usually large media files are to blame.
My first recommendation is this: download and run the free OmniDiskSweeper. This will identify the exact size of all your folders - you can drill down into the subfolders and figure out where your largest culprits are. For example, you might find that your Pictures folder contains both an iPhoto Library and copies that you've brought in from a camera but are outside the iPhoto Library structure. Or perhaps you have a lot of purchased video content in iTunes.
If you find files that you KNOW you do not need, you can delete them. Don't delete them just because you have a backup, since if the backup fails, you will lose all your copies.
Don't worry about "cleaners" for now - they don't save much space and can actually cause problems. Deal with the large file situation first and see how you get on.
Let us know what you find out, and if you manage to get your space back.

For the 2013 versions of macbook pro should I purchase 32 bit windows or 64 bit version to be able to install it on macbook and use windows with bootcamp?

for the 2013 versions of macbook pro should I purchase 32 bit windows or 64 bit version to be able to install it on macbook and use windows with bootcamp?

Then you might check at any of the other university book stores or software stores or any computer store in town for the 64-bit version.
If you want to use the 32-bit version from the school (you probably get it for free or very cheap) then you could purchase Parallels and run it as a virtual machine concurrently with OS X. There are some caveats:
1. You have to purchase Parallels (there may be an academic discount.) List is $79.95.
2. Your computer needs minimally 4 GBs of RAM, but realistically 8 GBs would be better.
3. Parallels creates a pseudo-drive on your hard drive. It could easily require 50 GBs of disk space.
Accommodating these might be more costly than buying 64-bit Windows 7. And, if you look online you may find them with an academic discount (or may be able to order it through the school.)

Trying to install Windows with Bootcamp

Hello. First, I do know this has been a recurrent trouble for a lot of Mac user who have tried to install Windows using Bootcamp. Believe me, I've looked it up both here in the Apple Communities and in saint Google. My situation is, however, that I have replaced my optical drive with a SSD, and now my optical drive works externally, via USB. Everytime I try to install Windows in a dedicated partition in the SSD, it just stays forever in a blank screen with blinking cursor.
Apple's troubleshot won't work for me, and I'm beginning to think that the issue has more to do with the optical drive itself. I tried:
To install Windows on the HDD instead of SSD.
To unplug every USB (even mouse), except for the optical drive with Windows 7.
To install it via USB stick (creating a bootable .iso with Disk Utility). In this case the usb stick does not even appear when holding option key.
To try another Windows 7 version (32/64 bits).
I have even read it might be because of a bad installation of the RAM memory... this makes no sense?!
If anyone has encountered this same situation, I'd appreciate some help. Hope I can get this done, because Steam's Age Of Empires won't ever work in OS X :S
Thank you all for reading and helping!

If your Mac was originally configured with a built-in Optical drive, and it was later replaced, Bootcamp knows your original configuration and will not work properly in the modified configuration, because it uses your Mac's model string (found in About This Mac -> More Info -> System Report -> Hardware) for example, MacbookPro 11,3. The only supported method to install Windows is to restore the original HW configuration and install it and then move hardware around.
