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.

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.

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 800MT/s 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.
