Asus P8P67 Only using 25% of my RAM

post #1 of 11
Thread Starter 
Got my 1155 setup yesterday still working stuff out but i just want to know if there is a way i can make my board use all 4Gbs of my ram if i run the RAM test in prime95 it uses 50% and then my computer is like 100x faster so i want to know if there is a way to make my mobo use 100% of my RAM.

Read somewhere about enabling memory remap feature in BIOS for systems x64 running over 3GB of memory.
Quote:
For a 32-bit OS with more than 3 GB of RAM, it should be off.
For a 64-bit OS with more than 3 GB of RAM, it should be on.

You have to select 'Custom' and enter in the amount of RAM you want to utilize. Open up Task Manager and determine how much is currently available, and then type that into Prime95.

How can i enable memory remapping on my P8P67 so that Windows is always using my full 4Gbs of RAM.

For stress testing a system with 4GB of RAM:
Set P95 to "Blend". But don't hit start yet. Next, set it to "Custom". This forces "Blend" tests to be ran, but you can change them manually. Now, set total RAM usage to 3072-3200 (3072 is your total amount minus 1GB, which is what I always suggest).

EDIT:
Windows will use all 4GB of your RAM when it needs it. Check in task manager, you should show (under "Physical Memory") that you have 4096MB Total RAM.

The amount of RAM a program uses depends on the programmers. For example, firefox uses more ram than most of my games before 2007.
