Answers to some of the questions that are most Frequently Asked.
Should I buy same capacity memory module for my upgrade, or can I mix a different size?
For systems employing SDRAM technology, mixing different sizes is allowed. There are some systems, however, that require modules to be installed in pairs. Typically, these are the ones that have the Dual Channel Mode. Check our Memory Configurator for the right memory configuration applicable to your system.
What is Dual Channel mode?
The dual channel mode was introduced when the DDR memory came about. This technology requires two matching pairs of memory modules to be installed so that that the system runs at optimal performance. In dual channel mode, the effective bandwidth becomes twice the standard size, that is, if you have a Dual Channel PC3200, the peak bandwidth becomes 6.4GB/sec instead of 3.2GB/sec. This is because the two sets of identical memory doubles the data paths that can be used simultaneously allowing data to move faster, minimizing time delays between read/write processes. Before you upgrade, consult your system's specifications to verify if your motherboard supports the dual channel function.

Norton memory test failed after installing new memory module
Norton Memory test does not work on systems with more than 256MB memory. This problem is caused by systems using Windows 95, Windows 98, Windows 98 Second Edition and Windows ME with 256MB or more memory.
Defining Maxfilecache settings in System.ini file solves this problem..
Please click on Start button and select Run.
Please type: SYSEDIT and click OK.
Please select SYSTEM.INI Window to display its content.
Please find the [vcache] section, add the MinFileCache= and MaxFileCache= lines to it, if [vcache] section does not exist then please create it.
The value for these settings are in kilobytes. For example, if you want to create a 50-MB cache that cannot exceed 55 MB, the lines would be as follows:
[vcache]
MinFileCache=51200
MaxFileCache=56320
Please save new configuration by choosing File menu and clicking Save

I have purchased UScomtek module and it doesn’t fit into the memory socket
You may be installing the memory module the wrong way. Flip it to the other side so that the notches on the module line with those of the socket. If the module is way too long or too short than the socket, or if notches don't align even after flipping over, then you may have ordered the wrong memory. Please contact our Technical Support for information on how to apply for an RMA (Return Merchandise Authorization).
