Computer unplugged from power, open the computer case, observe Anti-Static Precautions, and install the Ram Memory module, or modules.

The Sony Vaio RC110 desktop computer uses DDR2 Sdram ram memory.

(Double Data Rate 2 - Synchronous Dynamic Random Access Memory)

The Maximum Total Amount is 2GB's of ram memory.

(2 GigaBytes.
Giga = Approximately 1 Billion
Byte = 8 Characters
Characters can be Letters, Numbers, or Symbols)

The 'speed' of the ram memory used is 533MHz.

(MHz = MegaHertz
Mega = Approximately 1 Million
Hertz stands for Cycles per Second.

'Speed' is a relative term that actually is misused.
It's actually Frequency Rate.
What Frequency Rate does the ram memory operate at.
It operates in Cycles per Second of Frequency Rate.

Ram memory for your computer can operate Up To, a frequency rate of 533 Million Cycles per Second )

There are two ram memory slots on the motherboard.
EACH slot can hold a Maximum amount of 1GB of ram memory.

This is what DDR2 Sdram at 533MHz looks like, (PC-4200, also referred to as PC2-4200),

DDR2 Sdram has 240 gold plated contact pins, on the bottom of the module.

(Ram Memory Module is proper speak for Ram Memory 'stick')

120 contact pins on each side.
There is a Locating Notch on the bottom of the ram memory module.
At a casual glance the notch may look to be centered.
It is Not.

At the bottom of each ram memory slot on the motherboard, is a Locating Lug.
The Locating Notch of the ram memory module, must line up with the Locating Lug in the ram slot.

Observe this close-up photo of DDR Sdram.
(DDR Sdram has 184 contact pins)

(You can click on the photo to enlarge)

Note that the Locating Notch is 40 contact pins from the Left side, and 52 contact pins from the Right side.
The above is just an example, to help explain the location of the Locating Notch.

Also note the Lock Notch on each end of the ram module.
There are two on the Left side, and two on the Right side.
Only one notch on each side is used.

Each ram memory slot on the motherboard has a Lock Arm.
This arm resembles an ear to me.

The Top of the Arm is brought out to the outside, to release the ram memory module.
The Lock Arm pivots.

There are two Lock Arms, each lock arm should be simultaneously unlocked. (Both Arms brought to the outside at the same time)
This action brings the ram memory module up out of the ram slot.

Once you have removed a ram memory module, you will note that each Lock Arm has a small slot at the bottom.
The outside bottom corners of the ram memory module, fits down in these slots.

You will also note that there is a protrusion, or 'Bump' on each Lock Arm.
This 'Bump' fits in the Notch at the end of the ram memory module.
(Sometimes the bump does not fit exactly in the notch. But it will fit in pretty close)

When you install the ram memory module;

A) Line up the Locating Notch with the Locating Lug

B) Make sure the Lock Arms are pivoted to the outside.
(Top of lock arm is pivoted out)

C) Line up the bottom corners of the ram memory module, in the slots at the bottom of the Lock Arms.

I use the thumbs of my hands to gently push down on the ram memory module's top, and my fingers to bring the Lock Arms up, at the same time.
When the ram memory module is seated correctly, you should hear two satisfying clicks.
The clicks, are each Lock Arm bump seating into the outside Notch, at the end of the ram memory module.

New ram memory may be a little 'stiff', when installing. Especially when you are installing into a ram memory slot on the motherboard, that has never been used.

You may find this video will help,

Anti-Static Precautions:

Your body carries Static electricity.
Static will fry out (Short Circuit) the hardware components inside a computer.

Computer unplugged from power, working on a table, computer case open, TOUCH the metal frame of the open computer case.
This action will relieve your body of static.

Should you get up, and walk away in the middle of working on your computer, upon your return be SURE to Touch the metal frame again.

(Best method is to buy, and use an ESD wrist strap, and connect the alligator clip to the metal frame. Average cost is around $6.
Electro Static Discharge)

To open the Sony Vaio VGC - RC110G desktop computer case:

The above is Sony eSupport, and the download page for documentation on the Sony Vaio VGC-RC110G desktop computer.

Under the bold type heading - Manuals, I would like you to click on
User Guide, in the list.

A small window will open to the upper left. It is the User Guide in PDF file form.
Maximize the window.
(Left-click on the Maximize icon. At the top to the left of the Red X)

Under the Bookmarks heading on the left, go down to the sub-heading
Upgrading Your VAIO Computer, and left-click on the + sign.

Now left-click right on the sub-heading - Opening and Closing the Computer.

Or alternatively,
A) Use the blue Down Arrow at the top, and go to Page 94


B) Put your mouse cursor in the page number box at the top, left-click once, type 94, and press the Enter key.

(Should you not be familiar with PDF files, and wish to save this User Guide to your computer, please state so in a Comment, and I will state how.
This way you can burn the User Guide to a CD disk, and have it for future reference, and not have to download it again.

You can also delete it from your computer after saving to CD, and have more space on your Harddrive)

    Should also like to add:

    1) Observe Anti-Static Precautions BEFORE you take that ram memory module, out of it's anti-static protective bag.

    2) Handle the ram memory module by the body of the module. (Where the Black rectangular DRAM chips are)
    Refrain from touching the gold plated contact pins on the bottom.

I need to ask if you're comfortable working inside your case,and also whether you've done any other upgrades already.
The computer was originally configured with 1GB of RAM and can take a max. of 2,so it's not a huge job if you're willing and able.
If you've had the case open in the past,do you know how many open RAM slots you have now?
Post back and I'll see what I can do.

First you need to find out what Memory ( Ram ) it requires as there is DDR DDR2 SODIMM but seeing as it is a newish computer it could be a DDR2. Way to find out is looking up on the internet. Unplug everything from the computer , then look on the back. With the computer front facing you remove the 2 screws on the left side and then pull the side panel back and away from the tower. Look inside and you will see a silver box with a fan on it ( thats the Chip fan ) and next to it you should see some Sticks that are green and have black squares on them, what you do is note what slot is free and make sure you grab the new stick on each corner and push it down onto the free slot ( as long as the 2 tabs either side of the socket are pulled away, then it will jsut clip into place with a little pressure.

Thats a Ram change, but make sure you know what type it is.

Hi there. I am a RAM rookie. I have GAteway MX7118. are there two memory slots or one. It comes with 512 does that mean there are two slots and I can add a 1GB for A total of 1.5GB ?

Hi, defending on your cpu board usualy there are two slots, also if your board capable to 1 gigabytes memory, if your memory is DDR u can add 1 GB up . if your memory is SD you cannot add higher than 712 MB. if your memory is 512 and you want to add 1GB the total should be 1.5 you are correct in your calculation. thanks

I want to add 4GB of DDR3 memory, what further info to I need to know about the memory?

Newegg has a great site to find the correct and most compatible memory for you Here.
To maximize your ram speed, use the same speed and types of ram

For example, if you have a 1GB right now, add three more 1GB than putting in a 2GB and 1GB.
If you have a 4GB ram stick right now, add another 4GB and not 2x2GB. Also make sure the MHz on the ram is the same, (1333, 1600, 2000)

Enjoy upgrading your computer!

I have 512 mg of memory. Would there be a big difference if I add a 1 gb stick and keep the 512 mb , as oppose to removing the 512 mb and replace with two 1 gb sticks?

The performance of your laptop will improve if similar memory is placed in each of memory slot.If 1gb memory and 512mb memory are placed in available slot you will only get the performance of a single 1gb memory.but two 1gb memory are used performance will be similar to a 2gb ram or more.

Can I add 1GB memory chip in 2nd slot with a 512MB chip in 1st?

You can upgrade by inserting a 1GB PC2100 DDR SDRAM DIMM. I would put the 1MB in the first slot and move the 512MB chip to the second slot.
The 1GB should cost around $40.

Upgraded Dell Dimension 3100 memory to 2 Gigs - Windows XP fails

Did you add the two sticks with the 512 or remove the 512 and add the two 1gb sticks? Try booting the machine with ONLY the 1gb sticks in.

Your machine supports 1gb modules but they can't be higher than 533MHz. Check that the memory you purchased was either PC3200 (400MHz) or PC4200 (533MHz) and is 1.8v. If you post the part number off of one of the modules I can look it up for you.

Hard disk and ram

Hello Kevin Shaggy...

Let me see if I can help you out a bit...
Adding a 160gb to a 40gb does give you 200gb. BUT!!! you will loose a little bit on each one after formatting the harddrive. The new drive will wind up being about 157 or 159gb give or take a little.
ANY harddrive partition, whether it is a c:, d:, DO have to format EACH drive letter.
If you partition your 160gb harddrive into 2 parts, (2) 80gb drives, then they would get two drive letters and both of them get formatted.
IF the 40gb drive is C: then the new 160gb partitioned in half would be D: & E:.
CDROM Drive would be F: and so on....
Floppy Drives, CDrom Drives, DVD Drives, you do not have to format like a hard drive...

If you add a 1gb stick of memory to your existing 256mb stick of memory then you WOULD have 1gb + 256mb. If you remove the 256mb and just add 1gb, then you would just have 1gb.
