RAM I have a 256 ram. want to upgrade. how much capacity ram can i upgrade to and what will be the cost

I cannot directly answer that question because you did not supply the motherboard model number. You will have to look this up yourself, here is the url for Mercury support

The model number is usually printed on the motherboard, find it and you can download the manual, specs and drivers.

You can upgrade your Aston Digital Passport RAM up to 1 gb maximum. It supports this kind of RAM. Thank you.

Please check in to your Bios system maybe share memory Video or capacity is setting

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.

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

Thanks,

You can upgrade to 2Gb ram. I dont think your notebook will support 4Gb ram. A 2Gb Transcend ram will cost you around 1500 bucks INR

You should check with the folks at Dell since whoever wrote their technical manuals for this machine can't do basic math. There are 2 memory slots and each can handle a maximum capacity of 512MB, yet they claim the maximum capacity for the machine is 2GB instead of 1GB. Using 512MB modules would probably work.
