512mb is the max memory amount this computer will accept.

Each memory slot can hold SDRAM, PC133 with a maximum of 256MB per slot. Two slots total. Hope this helps.

How to install memory stixs


In an Acer Extenza 5420 series of Notebook PC?

Well you came to the right place

Here have a seat, and let me show you;

1) Remove ALL power. Remove the AC adapter (Charger), and Battery.

2) Here is a Bottom view of your laptop,

http://www.ebay.com/itm/Acer-Extensa-5420-Case-Bottom-15-4-Black-Cover-Speakers-Original-Genuine-Laptop-/170983023419?pt=US_Computer_Cases&hash=item27cf61e33b

Bottom left corner shows the Battery has been removed.
Remove the large panel above it,

http://www.ebay.com/itm/Acer-Extensa-5420-5520-Hard-Drive-RAM-Memory-Bottom-Cover-Door-60-4T305-002-/190741766831?pt=LH_DefaultDomain_0&hash=item2c691862af

Looks to be 6 Philips head screws to remove.
The panel lifts up on the LEFT side. There are TABS extruded from this large panel, which go into the Base Enclosure, (Bottom Cover), on the Right side.

From the Specifications on Acer's Support website,

http://support.acer.com/acerpanam/notebook/0000/Acer/Extensa5420/Extensa5420sp2.shtml

,it states;

System Memory: -> Up to 2GB of DDR2 667MHz memory; upgradeable to 4GB using two SO-DIMM ram memory modules.
(Dual-channel support)

From what I can see, looking at the motherboard by itself; there are TWO ram memory slots,

http://www.ebay.com/itm/Acer-Extensa-5120-5420-7120-7420-TravelMate-5220-AMD-Motherboard-MB-TKP01-002-/350455821339?pt=Motherboards&hash=item5198cb741b

Towards the Top you see the White processor socket. Upper corners are cut off, and there is a single screw in the top/middle.
Right above it are two white Ram Memory slots.

EACH ram memory slot will support (Use) 2GB of DDR2 at 667MHz.

2GB = Amount
DDR2 stands for DDR2 Sdram, and is it SO-DIMM to fit in a laptop.
667MHz stands for 667MegaHertz.
The frequency rate ('Speed') that the Ram Memory operates at.

The TOTAL amount of ram memory for the laptop is 4GB.
That means you can use two modules, ('Sticks') of DDR2 Sdram at 667MHz.
Or also stated as PC2-5300.

Just make SURE it is SO-DIMM, or you will be getting the larger DIMM ram memory used in a desktop computer.
An example of SO-DIMM,

http://en.wikipedia.org/wiki/File:1GB_DDR2_SO-DIMM.png

Note the Side Notch on Each side.
The half-moon cutout.
Note the Locating Notch on the Bottom.

Also;
Everywhere on the Ram Memory module, EXCEPT the gold plated contact pins at the Bottom; is the BODY.

The Body is coated with a see-through protective plastic.
Handle the Ram Memory module by the Body.
Refrain from touching the gold plated contact pins.

[WORK on a table. {Or workbench} DO NOT work on a bed, couch, or directly on a carpet floor! High areas of Static electricity.
Static WILL fry out, (Short Circuit) computer hardware components]

If you have two Ram Memory modules, one will be stacked on top of the other one. You remove the top one first, then access the bottom one.

To remove a ram memory module, simply ease the spring clips on either side -> OUT.
Out away from the Ram Memory module.
This action takes the 'Bumps' on the Spring Clips, out of the Side Notches on the Ram Memory module.

DO NOT get carried away. Just ease one spring clip out, then ease the other one out. You can bend the spring clips if you are too rough.
When both spring clip 'bumps' are out of the way, the Ram Memory module will spring up slightly.

Remove AT THAT ANGLE.

Slide the Ram Memory module out, at the same slight angle, (30 degrees?), that it just popped up to.

IF you lift the Ram Memory module straight up, you WILL damage the gold plated contact pins on the bottom of the Ram Memory module; and the contact pins in the Ram Memory slot.

To install a Ram Memory module, look at the location of the Locating Notch on the Bottom.
This aligns with a Locating Lug, in the bottom of the ram memory slot.
ONLY goes in one way.

Locating Notch aligned with Locating Lug, slide the Ram Memory module in, in the SAME slight angle it came out at.
Make sure the gold plated contact pins of the Ram Memory module, are well seated in the ram memory slot.

(Ram Memory module is pushed in tightly, in the Ram Memory slot)
Then press down on the tilted up side, until the spring clips lock in place.

Here is a video demonstrating the above, but NOT your laptop,

http://www.youtube.com/watch?v=MbPaR1Ci-Ug

IF, you are ONLY installing ONE Ram Memory module, it MUST go in Slot 1. Also known as DIMM 1.

The Processor (CPU) reads what is in Slot 1 -> F-I-R-S-T.

Know this;
If you are using the regular Windows XP Home, or Pro; it is the 32-bit version.
If it is the Windows XP Pro 64-bit version, it will state so.
Either on the body of the laptop, or go to System Properties.

[Left-click on Start > then Right-click on My Computer.
Left-click on Properties at the bottom of the drop down list ]

Windows Vista 64-bit will state so also.

Point?
IF you have a 32-bit Operating System, your laptop will ONLY recognize about 3.2 to 3.5GB of ram memory; if you have 4GB installed.

Takes a 64-bit Operating System to recognize all 4GB.

For additional questions please post in a Comment.

IBM T23 wont turn on after adding new RAM


Hi - according to memory suppliers your T23 has the following memory capacity / requirements:

  • IBM ThinkPad T23 maximum RAM capacity: 1GB
  • Your IBM has Two (2) memory slots or sockets
  • Module upgrade PIN count is: 144-PIN
  • The memory speed is: SDRAM 133MHz, PC133
  • The laptop DIMM type for the ThinkPad T23 is: SODIMM, SO-DIMM, Small Outline DIMM
  • Non ECC

If you are meeting these requirements, you may have a defective module.

Also, according to Lenovo's page on the machine:

Memory
The system has 128MB or 256MB of memory standard and can be configured for up to 1GB of addressable memory. Memory options up to 512MB SDRAM SO DIMMs each can be added in the two available slots for memory expansion. The standard 128MB of memory is expandable up to 640MB and the 256MB of memory is expandable up to 768 MB of addressable memory with 64, 128, 256, or 512MB SO DIMMs without removing the 128MB SO DIMM that is standard in one of the internal slots for memory. For customers that need the maximum 1GB to which memory can be expanded, it is necessary to replace the 128MB or 256MB card with a 512MB card plus add another 512MB card in the extra slot. Only 133MHz DIMM memory can be used in this system. The use of 100MHz DIMM memory is not supported in the T23 systems.

This means yo can trouble shoot the 512MB modules individually by installing one of the original 128MB modules and one of the new 512MB modules (for a total system memory of 640MB). If it does not boot, try again with the other 512MB module. This will help you identify a defective module that may be preventing the machine from booting.

I hope this helps & good luck!

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.

RAM upgrade is not working


A 200-pin PC-3200 SODIMM should work in your machine but it will clock down to 333MHz. Your computer has 2 slots with a max of 512MB per slot (1GB total system memory). For maximum compatibility you should stick with a low density (16-chip - double-sided) PC2700 DDR-333 SODIMM with a CL of 2.5. Link below to see an example:

Memory upgrade


We have the memory you need. Memory-Up is committed to provide the best memory and excellent services for all of our customers. We know that sometimes it is a bit confusing to buy the correct type, speed, and capacity of memory for your system. Therefore we hope that these tips below would help you for buying the new memory.
Memory Upgrade Tips

What is Compatibility and Memory Density Issue?

Memory module can be composed using different type of memory chips and therefore created different type of density for the module. For instance, a 512MB PC2700 DDR SODIMM memory can be composed using eight 32x16(High Density 512Mb technology) memory chips or sixteen 32x8(Low Density 256Mb technology) memory chips. As the laptops are equipped with different memory chipsets, some older laptop (chipset) would have compatibility issue working with the modules that is built with the newer 512Mb technology. Using the Not-Compatible memory will result the laptop to either not boot or only recognizing half of the memory modules. Thus that is not the correct memory for your system. Our Memory Finder and Memory Scanner will help to eliminate those problems and find the correct memory for you. We guaranteed the memory to work or your money back. 

How much memory do I need?

Here are some general descriptions for different type of users and the amount of memory they would need for their systems.

Normal User: The system is mainly used for checking e-mails, processing word/excel file, and web surfing. Suggestion: 512MB to 1GB of system memory. 

Power User: The system is mainly used for playing computer games, editing photos/videos, running database queries, or multi-tasking environment. (Surfing web/Processing Word/Excel File/Listening to Music). Suggestion: 1GB to 2GB of system memory.

Super User: The system is mainly used for running large number of database queries, professional editing of photos/videos, heavy multi-tasking environment. Usually a server or a workstation would be considered as Super User due to the multiple accesses from users. Suggestion: 2GB and above of system memory.

How much memory and memory slot do I have with my system? 

You can download our Memory-Scanner to find out the the amount of memory that you have and the memory slots that are available for upgrade. 

How many memory module should I buy?

It is recommended to purchase one module with bigger capacity than two modules with smaller capacity. For instance, if you can buy either one 1GB memory module or two 512MB memory modules for your system, it is recommended to get one 1GB and leave the other memory slot empty for future upgrade if necessary. 

Note: For systems that supports dual channel memory mode, although memory modules need to be installed in pairs to enable Dual Channel Memory Mode, we still recommended users to purchase one bigger module than two smaller modules since Dual Channel Memory Mode has only a minimal improvement in the actual system performance.

What if I want to mix different memory together?

Different sizes/speeds of memory can be used together as long as their specification are qualified by the systems. For instance, a laptop can use one 256MB and one 1GB of memory for the total of 1.25GB system memory. Mixing two different speeds of memory modules would result the system to run at the speed of the slower memory between the two modules. We recommend users to use our Memory Finder or Memory Scanner to find the correct memory for your system.

Upgrading acer laptop RAM


Hi,
You Can Actually Upgrade This To 2 Gig Memory.
Each Slot Will Take 1 A Gig Strip.
I,d suggest Buying another 256 mb Strip, To Put Into Slot 2.
Or Buy a 512mb ( Half Gig ) Which Will Give you 750mb With your Existing Strip Already In There. ** Recommend 1 Gigabyte Max** 2 gig of Ram in This Baby Would Probably Start Glowing.
You Can Buy DDR/266/333 In 256/512/1 Gig Strips. These Are Commonly Known As SD-RAM-Modules.
