i have a P5WDH- deluxe and in the bios it detects my full 4GB but allocates 800MB to other recources and said that only 3.2 is usable.
everest also says that the 4 banks are in use and it shows 1024MB on each bank.
as you see from the title i use vista ultimate x64
can someone please help as this drives me crazy.
i do not find other threads with this problem so sorry if i didn't found one.
i also tried google but it only gives me the x86 related 4GB problems(which i know does not work) but this is the reason i use vista 64 so i could use the full 4 GB
More aboutvista shows
You need to enable memory remapping in your BIOS. In some BIOS's, you need to go to the advanced settings, sometimes via CTRL-F1. What motherboard do you have?
Note that you will want to make sure you have installed the vista-64 patch BEFORE changing your BIOS settings. I forget which one you are looking for but it's the one that prevents blue-screening when you have 4 GB or more of RAM in Vista-64.
Where are you getting the amount of memory figure from? Is it saying there is 3.2gb free, or do you mean you actually have about 2.7GB free in vista?
1) I would first remove sticks to get less than 4GB. 2) Reboot and install the patch. 3) Restart Windows. 4) Shutdown. 5) Install RAM. 6) Reboot.
in vista i have 3.2GB available. i have a asus P5WDH my bios said that it allocates 800MB to other recources and i dont find this memory remapping. i will also try the patch
Look again, that motherboard definitely has a function to enable memory remapping. Take a look in Advanced - Chipset or something. If you can't find it, search Google. Vista64 won't show all 4 GB until you enable this and it is definitely there.
Yes, I have this MB too. Look at all possible places. Can't remember where too.
ok, installed the patch and enabled the remapping.
i have full 4GB now
thank you all very much
You can also try to reduce your Virtual Memory (Swap File) to something like 512MB. It's what I did and working fine. No need to slowdown your experience by using the HD! 4GB is really great!
