Memory is an important component of your computer, and selecting and managing it properly is vital to keeping your system up and running at peak efficiency. If your computer is an older model or if it lags or freezes, you may not have enough memory.
Upgrading is easy when you choose Kingston® system-specific memory. Designed and tested to meet the exact specifications of each brand name system, Kingston memory is easy to install and can improve not only your performance but your system’s lifespan.
Kingston’s Memory Finder makes it simple to find the exact memory you need.
If your existing memory is failing or already dead, rest assured that Kingston has the ideal replacement, customized to meet the exact needs of your system. Memory comes in a wide variety of models and speeds; choose yours based on your computer’s motherboard and the types of tasks you perform in a typical day – just make sure you choose ultra-reliable Kingston memory. Plus Kingston has all the tools and expertise to take the work out of selecting and installing the ideal module for your needs.
To ensure your peace of mind, Kingston memory is guaranteed to be compatible with the system for which it’s designed.
All Kingston memory for Acer is backed by a lifetime warranty and the legendary reliability that makes Kingston the world’s independent memory leader.

It may be due to chip density, especially if you have an older DDR3 based system. Your system may require 2Gbit (Gigabit) density DRAM chips and the memory you have installed uses 4Gbit density chips, which are not compatible. Not to be confused with the term Gigabyte, which refers to memory capacity, DRAM chip manufacturers are no longer producing 2Gbit chips. Therefore we're unable to manufacture compatible modules.
In Windows, click on the start button and open "Control Panel".Use classic view for Vista and 7. Then open "System". This will display basic information about the computer including the amount of RAM installed.
In MacOS, select "About This Mac" or "About This Computer" from the Apple menu in the upper left corner of your Desktop. This will provide information about your Mac's total memory (built-in memory plus DIMMs or SIMMs installed).
In Linux, open a terminal window and enter the following command: cat /proc/meminfo
This will show the total amount of RAM as well as other memory information.
First, make sure you have the correct memory for your notebook. Refer to Kingston's online Memory Search at www.kingston.com for assistance. After confirming that you have the correct memory for your system, do the following:
Note: Kingston is in no way responsible for any problems resulting from flashing the BIOS. Flashing the BIOS is merely a troubleshooting suggestion. Customers who flash the BIOS do so at their own risk. All instructions on how to upgrade the BIOS will be provided by the computer manufacturer or the 3rd party BIOS manufacturer and not by Kingston.
Additional memory will not necessarily increase the performance of your computer. It will allow you to run more programs or processes at once or more memory intensive programs. There may be a performance increase if the original amount of memory installed was close to insufficient for the programs and processes you use the computer for.
For desktop computers, shut down and unplug your computer and open the case. Please note: The higher capacity memory should be installed in slot 1 followed by the next lower capacity memory in slot 2 and so on. Please refer to your motherboard manual for proper slot identification.
Remove the memory module as shown in Fig 1. Push the tabs (1) outward and the module will gently pop out of its slot (2). Remove it completely from the slot.
To install the new memory module, see Fig 2. Push the tabs (1) that are at the ends of the memory socket outward and align the memory notches with the key of the memory socket (2), then push the memory down FIRMLY into the socket so the latches lock the memory in place (3). If the memory has been properly installed and you have the correct memory but it is still not being detected, you should make sure you have the most up-to-date BIOS from your computer manufacturer's website.
For notebook computers, please note that you need to shut down the unit and remove the battery pack and power cord before you remove/install memory. Push the memory into the socket FIRMLY so that it makes good contact (it is important to push the memory in FIRMLY) before pushing it down to lock it in place (see figures below) . Once the memory has been installed, put the battery back in your unit and supply power using the power cord and not solely from the battery. If the memory has been properly installed and you have the correct memory but it is still not being detected, you should make sure you have the most up-to-date BIOS from your computer manufacturer's website.
BIOS - Basic Input/Output System is installed on the computer's motherboard. It controls the most basic operations and is responsible for starting your computer up and initialising the hardware. It is data that is usually held on a ROM chip and can be updated by "flashing" the BIOS. BIOS upgrades may correct errors, support new CPUs, and support new hardware including memory. BIOS updates are usually obtained from the computer's manufacturer's website.
*NOTE: Kingston is in no way responsible for any problems resulting from flashing the BIOS. Flashing of the BIOS is merely a troubleshooting suggestion. Customers who flash the BIOS do so at their own risk. All instructions on how to upgrade the BIOS will be provided by the computer manufacturer or the 3rd party BIOS manufacturer and not by Kingston.
Parts sold in kits (denoted by "K2" or "K3"in the part number, e.g. – KVR400X64C3AK2/2G) are specifically packaged for use in Dual or Triple Channel motherboards. Although Dual and Triple Channel technology resides on the motherboard itself (inside the chipset), the memory modules need to be installed in pairs or sets of three for Dual or Triple Channel mode to function properly. Identical modules packaged in a kit work best because the motherboard will be accessing all the memory modules as a single memory location with a wider bandwidth. Kingston suggests the use of modules sold in kits for Dual or Triple Channel enabled motherboards.
Yes. In most cases if the computer supports a slower speed, it will clock down to a slower speed as long as it is the correct memory type (DDR, DDR2, etc). However, be aware that the clocking down function depends on the computer and it isn't guaranteed to work in every case.
In many cases, the BIOS or a diagnostic program will report the memory bus frequency, which is half of the frequency for DDR type memory. As its name implies, DDR (Double Data Rate) data rate provides twice the memory bus frequency. So if the memory bus speed is 800MHz and you are using DDR3-1600 memory, the RAM is running at the correct speed.
ElectroStatic Discharge, ESD is simply the discharge of built-up static electricity. ESD should not be taken lightly as this is one of the few things that an individual can do to damage or destroy their computer or hardware components. It is like when you rub your feet on the carpet and you touch something metal. ESD can occur without the user feeling a shock and will occur when only working on the inside of the computer or handling hardware.
How to help prevent ESD
The best method of preventing ESD is to use an ESD wrist strap or an earthing mat or table. However, because most users do not have access to these items, we have included the below steps to help reduce the chance of ESD as much as possible.
