512Mb - 1024Mb Memory upgrade problem

I am trying to upgrade my 512Mb of RAM to 1024Mb. I have removed the two 256Mb sticks that were fitted as standard and replaced them with two 512Mb sticks. However the system does not see the new RAM as 512 Mb sticks but each as 256Mb. The computer operates correctly apart from the RAM being 512Mb when it should be 1024Mb.
I have fitted 2 x 512Mb 200 SODIMM PC 2700 CL2.5.
I have removed 2 x 256Mb 200 SODIMM PC2700 CL2.5

The laptop is a Sony Vaio PCG-K76P

Can the LG Xnote RD405 laptop intially with 1gb RAM be upgraded to 4 gb using two 2gb RAM's ? Please help me by providing an answer clearly, Thanks in Advance.


Here is the memory specifications from LG.

Maximum Size: Each slot is 1024MB and can be expanded to 2048MB.
SO DIMM Type for Memory Expansion: DDR2 SDRAM SO-DIMM (256MB, 512MB, 1024MB)

It can take a maximum of 2 gigabytes of ram. It will take two 1 gb sticks. It uses DDR2 laptop ram. You need to check to see if you have one stick that has 1 gb or 2 sticks that have 512 mb each. That will tell you if you need to buy one or two sticks of ram at 1 gb each. You will be able to tell a difference going from one gb to two gb of ram. I think it would be worth the investment if you plan on using the computer for another year or more.

hello, here's a part of the spec from the hp website. It looks like you've got 256mb on board memory and one expansion memory slot in which you can fit a 1024mb card, giving you a max memory of 1280mb (1024+256).
Hope this helps!

Remove the "new" stick of RAM, and re-insert your "old" stick of RAM, and start it.
If it still beeps, how many times does it beep, and is it a "short-long-short" type of pattern?
The number of beeps is important.

Does the manual for the motherboard indicate that it supports a maximum of 256MB per stick?
512MB per stick? 1024MB per stick? What's the size of the "old" stick of RAM?

Check that the video-card is properly "seated" into its slot, because an improperly-seated card (knocked loose when you changed the RAM) could cause the beeping.

This laptop came with 128mb ram, you can safely install 2 sticks of 256mb for a maximum of 512mb with no bios update.
You need pc100 sodimms.
Amazon or ebay will be the best bet as this memory is expensive now from a retailer.
I found 256mb sticks for under $10 buy it now on ebay http://cgi.ebay.co.uk/256MB-SODIMM-PC100-SDRAM-256-MB-PC-100-LAPTOP-144-Pin-/190411543153?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item2c55699271

Ram memory Problem?


Go to http://www.memoryx.net and run the 'Identify my computer' bit, clicking on 'Scan my system' and follow instructions.

The other thing is that if the MAX is 512, you'd want low-density memory.
