<br />
Please contact the hardware vendor and upgrade your BIOS. It will show full memory automatically.<br />

If you boot into the BIOS what does it show as available memory in there?<br />

I think processor is not detecting more than 4 gb. &nbsp;Please check this<br />

How much RAM does the system show when it posts (before OS loads)? I suspect that the hardware isn't recognizing the memory module. It could be of the wrong type, or in the wrong slot. This really sounds like a problem for your hardware vendor to resolve.

It is showing only 4GB before the server OS loads

It's certainly not an OS problem, but between your hardware and the RAM module. My guess is that the RAM you added isn't physically seated properly, or isn't compatable.

I tried changing slots with no luck<br />
<br />
I am sure there is some settings to be changed as there is 8 RAM slots and I used only 4 out of that

If what @kevinhsieh suggest doesn't solve your problem.<br />
what is the exact model number of your server and what slots are you putting the memory in.<br />

@D_Vante<br />
My server is Fujitsu Siemens <br />
Primergy RX300 S4<br />
<br />
1nd and 2nd &nbsp;2x2GB<br />
<br />
3rd and 4th I tried but it did not work.<br />
<br />
now additional RAM is in 5th and 6TH slots (2x2GB)<br />
<br />
So it should show 8GG

make sure in the BIOS under advanced Memory Redundancy is disabled<br />
<br />
When I look it up it shows you should only have 6 slots if a single processor and 12 if a dual processor

Physical memory not showing in system properties

Windows Server 2008 and Windows Server 2008 R2, based on the Microsoft Vista codebase, is the last 32-bit server operating system released by Microsoft. It has a number of versions, including including Foundation, Standard, Enterprise, Datacenter, Web, HPC Server, Itanium and Storage; new features included server core installation and Hyper-V.

Windows Server 2008

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.

Server Hardware

An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. Examples of properties typical of embedded computers when compared with general-purpose ones are low power consumption, small size, rugged operating ranges, and low per-unit cost. Modern embedded systems are often based on microcontrollers; the processor(s) used may be types ranging from general purpose to those specialised in certain class of computations, or even custom designed for the application at hand. A common standard class of dedicated processors is the digital signal processor (DSP).
