I have 4 sticks of 1gb corsair memory (ddr2) but only 2,94 GB is useable.

First i looked it up on YouTube. I have tried to set maximum ram to 4096MB but that doesnt work. (Msconfig)

Secondly i tried to reseat the ram. Didnt work either. The pc just got stuck in a boot loop. Just loads to Windows for some seconds, then reboots.

Any thoughts? :)
 
Solution
This behavior is the expected result of certain hardware and software factors.

Various devices in a typical computer require memory-mapped access. This is known as memory-mapped I/O (MMIO). Memory-mapped I/O uses the same address space to address both memory and I/O devices. To accommodate the I/O devices, areas of the addresses used by the CPU and other hardware must be reserved for I/O and must not be available for normal physical memory.The reduction in available system memory depends on the devices that are installed in the computer.

Solution
Are you running 32-bit Windows? 32-bit Windows has a 4GB address space and hardware like graphics card memory will need to be mapped within that space, meaning you might end up with only around 3GB accessible unless a 64-bit version of the operating system is installed.
