512 MB memory boards do not work in my Fujitsu Lifebook S2020

yes you can put 512 mb of ram even 2 of it because the capacity of your board is up to 1024 mb of ram but make sure that it is an sdram and it has the same specification on whar is your manual indicate besides on the ram size.

If new processor supports your old motherboard then you will upgrade system with your old motherboard.

If its not supported to new mother board then you have to buy new motherboard to upgrade your system.

Thanks.
Happy to help you.

the RAM upgrade will depend on ur motherboard capacity and specification.
u need to check ur MB manual
if ur MB can have only SD RAM then only SD RAM upgrade is possible...DDR will not work....
so be careful while buying ur RAM

intelD845GLLy MB...the following details are from the intel website

http://www.intel.com/support/motherboards/desktop/d845glly/sb/CS-012825.htm

System Memory Features
The D845GLLY board provide the following memory features:

• Two DIMM sockets supporting 3.3 V (only) 168-pin 133 MHz Single Data Rate (SDR) SDRAM DIMMs with gold-plated contacts
• Unbuffered non-ECC DIMMs only
• Maximum total system memory: 2 GB; minimum total system memory: 64 MB
• Serial Presence Detect (SPD) DIMMs only
• Suspend to RAM

Caution Do not use ECC DIMMs with the Desktop Board. Using ECC DIMMs could damage the Desktop Board.
Integrator's Notes:

• Registered DIMMs are not supported on the Desktop Board.
• This Desktop Board has been designed to support DIMMs based on 512 Mbit technology for a maximum onboard capacity of up to 2 GB, but this technology has not been validated on this board.

Note To be fully compliant with all applicable PCI33 SDRAM memory specifications, the board should be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. This allows the BIOS to read the SPD data and program the chipset to accurately configure memory settings for optimum performance.
hope this helps

Hi,

Make sure that you got the right memory module with this specs:

Memory

• DDR266 (266 MHz) so-DIMM 200 pin
• 2 DIMM slots; upgradable to 1 GB total memory (512 MB x 2)

or better go to this link http://support.fujitsupc.com/CS/Portal/supportsearch.do?srch=GUIDES

there's a step by step troubleshooting for memory modules. Also make sure you purchase memory module from Fujitsu or Authorized Fujitsu Dealers .

Okay, first things first. IF the memory you installed is 1024 and you are using the on board video and it is 512 MB, you will only have 512 MB usable memory. This is because the on board video uses the installed memory to function. What ever the video memory is, subtract that form the total memory. If this is not the case, try re-seating the memory. If the numbers still do not add up then if there are four memory slots, make sure the memory is installed in the same color slots. Most desktops with 4 memory slots have two slots one color and the other two another color. Make sure both memory sticks are installed in the same color.

try to replaced memory card or clean it first the pin of the memory card by using dry clothes

there should be a setting in the bios to adjust the shared memory with video.

Hello,
Most likely your MB is too old for this upgrade although there is a chance you could flash your bios (reprogram your computer's brain to accept the new memory providing hp has a flash for it).
here is a link for the latest bios flash for your computer, use at your own risk.

good luck.

The motherboard you mentioned supports DDR1 RAM.

For windows xp and general application 512 MB is enough.
But if you use memory intensive applications like image/video editing then you can opt for 1-2 GB RAM.

hi,
The max memory supported by your computer is 1024 mb..
(1GB).
You can verify it here in this link
Also when you do this the already existing 512 MB may be gone without any use if they had provided you as 256+256 in seperate slots
