    Memtest and Windows Don't See 4GBs Memory

    Is Memtest86 only seeing 3GBs?
    Why is CCleaner and DXDiag seeing 3GBs and Vista is seeing 4GBs?



    Thanks in advance.

    I too have seen this in some of my programs and from what i've learned, vista x64 can also run 32 bit programs. its possible that the programs that you're using can only see 3gb of ram and vista can see 4 is because most 32 bit programs won't see above 3, which is the xp and vista x86 limit.

    Hope that helps.

    had to set memory remap to enable.
    weird that that function isnt enabled by default.
    still not sure what it does but it fixed the problem.
