Amount of available memory limited to 256MB during boot poweredge1600sc dell server

I suggest you copy the school papers, and photos to disk/s, or flashdrive/s for safekeeping.
Then work on getting your computer to be faster.

1) A computer starts slowing down in performance once the Harddrive reaches 50 percent full.
You won't really notice until the Harddrive is at 70 percent full, but the computer has been slowing down all along

Remove unnecessary programs you do not use, and applications.
DO NOT remove Windows programs.
Just one's you have loaded from disk, or downloaded from the internet.

Go to Add/Remove Programs, and see if there any that can be deleted.
(Start > Control Panel > Performance and Maintenance > Add/Remove Programs)

2) Defragment the Harddrive.
Start > Control Panel > Performance and Maintenance > Free up disk space so programs will run faster

3) Clean up the Registry.
Every time you visit a website cookies are put on your harddrive. Tiny pieces of software, but after a while they add up, and take up harddrive space.

There are also fragmented files left behind after you have removed programs, and/or applications.
There are a lot of 'bits and pieces' left behind that are of no use, and take up harddrive space.

Using a Registry cleaner removes these fragments, and helps to speed up your computer's processes.
(Makes the computer faster)

I suggest CCleaner.
Why?
1) It works, and works well.

2) It's FREE. Works as well as paid for versions, and better than some paid for versions.
Don't let the fact that it's free fool you.

3) I have been using CCleaner for about 2 years now. Haven't had problem 1, and use it every time I'm off the internet.
Not advertising. Wouldn't do any good, lol! It's Free!

If you decide to use Ccleaner, come back, and post in a Comment, and I'll step by step you through using it.

4) Maximize the Ram Memory. Of course we all have to watch our budget constraints, especially with the world economy the way it is.

The Maximum Amount of Ram Memory is 2GB. (2 GigaByte)
There are two Ram Memory slots. EACH slot has a maximum amount of 1GB.
Uses DDR Sdram at 333MegaHertz. (333MHz) [ PC-2700 ]
It is the SO-DIMM style of ram memory.

Documentation for the Dell Latitude D600 Notebook PC, from Dell Support, indicates the standard amount of ram memory that is installed, is 256MB.

[256MB + 256MB = 512MB
512MB + 512MB = 1024MB or also stated as 1GB ]

http://support.dell.com/support/edocs/systems/latd600/en/ug/specs.htm

Scroll down to the bold heading > Memory
Look at the sub-heading in the chart at the left > Memory module connector.
Indicates > Two user-accessible DDR Sdram connectors.

In plain English > Two Ram Memory slots.

Look at the sub-heading > Memory module capacities
128MB, 256MB, 512MB, 1GB.

Plain English > Can use just one 256MB ram module, ('Stick'), or two of them.
Same with each amount listed.

Look at the sub-heading > Standard memory
256MB

Plain English > Comes from the factory with one 256MB ram memory module.

[Maximum memory = 2GB ]

With 256MB of ram memory, a crude comparison is that you could kick a football down the football field, and have to wait until next month for the other team to bring it back.
S-L-O-W!

512MB of ram memory?
Umm, next week.

1024MB? (1GB)
Now you're talkin'.
Return ball at the speed of a normal game.

2048MB? (2GB)
You'll think special effects are happening because the football game is almost over!

An exaggeration I'll admit, but the performance increase is worth it when using programs, and applications.
On the internet? You'll see an increase in performance, but nothing to really write home to Mom about.

'Optimizer', or 'Performance enhancer', or some other dribble advertised as the 'flavor of the day'?
Naa, I find them costly, and full of beans.

Just use the free software available, and tune your computer up through steps 1 and 2 above ,using what Windows has available.
Keep your money in your pocket, unless more Ram Memory is an affordable option at this time.

Hi,
From BIOS, change

Dell Dimension XPS M

Largest HDD Shipped 4.3 GB (Max HDD likely 20GB)

I assume you installed another 128Mb of RAM to give you a total of 256Mb.
It is most likely the 2nd RAM module is not compatible with the other RAM module. Try using the same make.
OR
Purchase and install a single RAM module 256Mb or 512Mb these are not expensive.

Shared RAM this is a term use to tell the customer that the size of video will defend on the amount of RAM that the computer has, for example almost all laptop now is just using a shared RAM for the video card meaning if you have 1GIG or RAM and the video card can be set to 256MB so the 1GIG ram will be deducted with the 256MB that was allocated to the video RAM......

In the bios there is an option to install OS, make sure this is flaged as off, when you reboot you will have access to the full amount of onboard ram.

you have a bad memory stick.

Turn off the option n the bios where it says OS Installed make sure it says os not installed
The Bios will only use 256 ram

You need to go into the bio and update the memory there and the Yellow ! will go away. Boot the PC, select the F8 key during post, go into the setting for Memory and accept the change and you should be good to go. Let me know //D

reinstall your server it will resolve your porb.
