Sony Vaio not detecting 512Mb sticks as 256Mb

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

    Thanks. Believe BIOS is auto/self detecting. It only appears as 512Mb in there also. Is there any way of "forcing" it to see 1024Mb? I have run Everest and it see's two 512Mb sticks of RAM installed

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.

I have a Tecra 8200 bought as used fitted with 256MB of ram. If I buy an extra 256MB which brings the total to the maximum allowed of 512MB is it likely that I will need to upgrade the bios to allow the...


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

make sure they are compatible with your computer, there are alot of electronic stores (circuit city) was the worst at it, but will sell you the wrong ones and say they are backwards compatible.. usually P4 2.8 can run PC2700, some run PC2100, which im hoping yours is PC2700... if so, make sure they are NON-ECC also... i would just get 2 1 gig PC2700 DDR 200pin sticks and stick em in... good luck

Adding RAM


If it has 4 slots and supports 2Gb max with 2 slots currently populated with 2 x 256mb chips you'll need to remove both those chips and install 4 x 512mb chips to reach the max of 2 Gb.
