I can't use full of My RAM (3.25 Usable from 4.00 GB)

[ Edited ]
Product Name: ASUS P5LP-LE Leonite2-GL8E
Operating System: Microsoft Windows 10 (64-bit)

I think I must update my BIOS from 5.20 to 5.23, right?


My PC is  HP Pavilion a6188d Desktop PC

Hello GoldThin


A BIOS update will not solve problem.


Your Motherboard will only support four GB's of RAM.

The Intel 945G chipset (found in that computer)  has a limitation of 4GB under a 32bit OS.  That limit is not fully addressed by the chip.  It has no relation to the BIOS.   This 3.25 GB limit is a universal limit of the chipset.  Source.
