All the follwing questions are base don memory CAPACITY that can be installed not how much is installed when it is produced and sold.
What controls the memory capacity for a given computer, the chip set used, the motherboard used or something else?
For instance, if a given chipset, say an Intel xxx, is isued on different motherboards will all of the motherboards using that chip set have the same memory capacity ( I relaize that the motherboard may have less slots than the chip set will support, but assuming both boards have same slots on it)?
Next step, assuming that you have the same motherboard, will all computers using that same board have the same memory capacty or can the computer manufacturer control the memory capacity during the assembly process or during programing?
Next step, assuming that all the computers have the same motherboard and are in the same brand of computer, will they all have the same memory capacity or will that vary with model?

Re: What controls memory capacity?
The maximum amount any computer will work on is 4 gigabytes. You may see some specialty models with 6GB but that is a waste of money because programmers write programs for a maximum of 4GB as that is the industry standard. The maximum memory capacity depends on the motherboard setup. For instance, any desktop can take up to 4 GB but some smaller laptops cannot. It depends on the company selling the product as they decide which motherboard to install. Netbooks, 7" to 10" screen can only hold 2 GB, while all 15" and above laptops can hold 4 GB. So basically 4GB max or less. Obviously 4GB will run faster than anything less. Memory is fairly cheap so always go with the 4GB. Second part of your question,manufacturers decide which motherboards go into which computers and the larger dealers like Dell, HP, Compaq, etc will always offer 4 GB. Inexpensive computers like Emachine cut cost by not spending the money for the best motherboards so they may only hold 2GB. Hope this answers your questions.

checkout this first - check the speed of the processor (above 2.2 ghz core 2 duo and above) - the harddisk capacity (250Gb and above) - if the operating system is geniune - if the cd/dvd drive can play n write both cds and dvds - check tha memory (Ram) capacity (2Gb and above) - check the functionality of both keyboard n mouse Then if all is well your good to go
Memory Upgrade for IBM ThinkPad R32 2658-xxx Laptop, the IBM ThinkPad R32 2658-xxx Laptop takes the PC2100 DDR SDRAM SODIMMs Memory Type, and comes installed with 128 or 256 MB (removable) of Memory. You can upgrade your IBM ThinkPad R32 2658-xxx Laptop to up to a maximum of 1.0 GB Memory, the system has 2 sockets to install Memory, already with 128 or 256 MB (removable) standard Memory installed. For best Laptop performance use the maximum amount of allowed Memory per slot for your Laptop.
good luck and do rate the solution if helps.
Your netbook should read SDHC(over 2 GB capacity) memory cards. The problem might be either the card slot driver, Which you should download if a newer one is available. Or in case you format the SD as DOS then it will only have around 2GB of space, You should format it as DOS32 or NTFS so you get the full capacity for the SD card. Some pirated rather cheaper memory cards have a lower actual capacity. With some compression technique the capacity presented is higher than it actually is. If you format it then it will show the real capacity. hope that is not the case!
According to the specs of this laptop model, it supports up to 4 GB of DDR2 533/667 MHz memory using two soDIMM modules. This means that you will have to replace the 512 MB memory module already installed in your laptop, & replace it with 2 soDIMM DDR2 533/667 MHz memory modules, each of 2 GB capacity.
visit vaio manual in ftp://ftp.vaio-link.com/pub/Manuals/Notebooks/ You can do this in two ways: opening your
notebook and taking a look on the memory modules already installed (we
will explain more about this later) or running a program like Everest (available on our download section).
We ran Everest (going to Motherboard, Chipset, Memory Slots) on our
notebook and found that it was using two 256 MB DDR-SDRAM PC2700
(“DDR333”) modules, for a total of 512 MB. click to enlarge Figure 1: Checking your current memory configuration with Everest.
If your notebook has an empty memory slot, just go to the computer
store and buy a new SO-DIMM module with the same technology (SDRAM or
DDR-SDRAM) and speed of any capacity you want – of course you need to
know the capacity limit of your notebook. You cannot install a 1 GB
module in a notebook that only accepts modules up to 512 MB, for
example. Our notebook – a Sony Vaio PCG-V505ECP – accepts modules up to
1 GB, for a total of 2 GB RAM, since it has two memory slots.
For example, if your notebook has one 256 MB module and an empty
memory slot, if you buy and install another 256 MB module, it will have
512 MB RAM. If you buy and install a 512 MB module, your notebook will
have 768 MB.
If your notebook already has two memory modules, you will need to
remove one of the installed modules in order to install the new one. If
the two modules have the same capacity, it doesn’t matter which one you
will take away, but if they have different capacities, remove the one
with smaller capacity. The new RAM capacity of your notebook will be of
the capacity of the remaining module plus the capacity of the new
In our case, our notebook has two 256 MB modules. So we will remove
one of these modules and install a new one on its place. We bought a 1
GB-module, so after installing it our notebook will have 1,280 MB RAM
installed (memory math is tricky, since 1 GB equals to 1,024 MB not
1,000; so 1,024 MB + 256 MB = 1,280 MB).
Good afternoon, mikieat! Yep! That should work. After installing the memory modules, the 3000 should come up and automatically detect and configure your added memory.

This is the link for the drivers for your laptop, Cut and paste it into the address bar in your internet browser and it will bring you right to the download page. It will also have the manufacturers contact info so you can get in touch with them directly for free and get the driver for your card reader. If it is not showing up it is not installed(driver). I do not see it in the list of drivers but customer service will be able to send you the link for the driver you need. Once you install the driver you will be able to use your reader. Also, The reader may not be capable of reading High capacity Cards. Any card over 2Gb is considered High capacity. This is the problem if you are trying to read HC cards in a standard capacity reader. The manufacturer will tell you whether or not it is a High capacity reader or not. If this turns out to be the problem you will just have to use an external USB HC card reader to read cards greater then 2 Gb. Hope you found this info helpful. And save the website in your favorite folder incase you ever need to download and install the other driver for your notebook. Thanks George Feel free to contact me if you ever have any other questions.
