Bootcamp RAM help and HD partition questions

[lancer6576]

Hi everyone, first time post.

I have just bought a new santa rosa MPB with 4gigs of RAM. I have installed bootcamp and have partitioned 30 gigs of space NTFS for XP.

My 4 gigs of memory are working on mac os, but in windows xp professional only 2.98 shows up when i get info about the computer. Is something broken or am I unable to use all 4 gigs of RAM in windows xp? Has anyone gotten more than 2.98 gig to register in xp on the new MBP? Is this a driver issue, or something that i have done?

Also if i want to make a third partition, FAT32, to transfer files between osx and xp. can i use disk utility to do it with out erasing everything? If not other then ipartition, is there any free partitioning SW out there?

Thanks so much for the help, i have looked everywhere on the forums and have found no answers.

I had the same issue well kinda, I have a MacPro with 3 gigs of ram and when I used bootcamp with XP it only showed up as 2gigs of ram.

I tried Vista and then it finally showed 3 gigs of ram.


I just wanted to post that your not the only one.

Thanks for the tip jeff...

Has anyone else had these memory problems with bootcamp and xp professional?

I've got a Mac Pro with 4 gigs of RAM.XP and Vista both only show 1.98 gigs.

So I wiped Windows.It sux anyway.

Only 2 gigs max will show up in XP reason being because of the bios and limitations on them. Hopefully this will get fixed with a update or something in the future. XP (32 bit os has this 2 gig limit) I don't think the 64 bit Windows based OS's have this problem however.

I was baffled about this myself and after quite a bit of research I found this information out.

The system memory that is reported in the System Information dialog box in Windows Vista is less than you expect if 4 GB of RAM is installed

For Windows Vista to use all 4 GB of memory on a computer that has 4 GB of memory installed, the computer must meet the following requirements: • The chipset must support at least 8 GB of address space. Chipsets that have this capability include the following:
• Intel 975X
• Intel P965
• Intel 955X on Socket 775
• Chipsets that support AMD processors that use socket F, socket 940, socket 939, or socket AM2. These chipsets include any AMD socket and CPU combination in which the memory controller resides in the CPU.

• The CPU must support the x64 instruction set. The AMD64 CPU and the Intel EM64T CPU support this instruction set.
• The BIOS must support the memory remapping feature. The memory remapping feature allows for the segment of system memory that was previously overwritten by the Peripheral Component Interconnect (PCI) configuration space to be remapped above the 4 GB address line. This feature must be enabled in the BIOS configuration utility on the computer. View your computer product documentation for instructions that explain how to enable this feature. Many consumer-oriented computers may not support the memory remapping feature. No standard terminology is used in documentation or in BIOS configuration utilities for this feature. Therefore, you may have to read the descriptions of the various BIOS configuration settings that are available to determine whether any of the settings enable the memory remapping feature.
• An x64 (64-bit) version of Windows Vista must be used.
