Frequently Asked Questions

1) How can I tell that my machine is recognizing the new memory?
The easiest method is to watch the computer count up the memory when the machine is turned on. If you do not see the count, or you have a Mac, you can check it once the operating system is loaded. Mac users can check the "About This Macintosh" option under the Apple menu. Windows PC users can check their "System Properties" control panel (the last item listed on the right side of the "General" tab).

2) What do I do when I get an error message when I boot that says "memory size mismatch"?
You should be prompted to enter the Setup menu or system BIOS. Enter the BIOS, then immediately save changes and exit (usually by using the F10 key). That should solve the problem.

3) My computer only recognizes part of the memory that I installed. I checked to make sure this part met the specs for my computer. Did I get the wrong item?
Possibly. Memory modules can be built in a variety of ways. Consult the owner's manual for your computer, to insure your computer can recognize the size of module you installed. Also check our product configurator to make sure you purchased the correct item. If you are uncertain, please contact us for further assistance.

4) Sometimes my computer locks up after I install my memory. Could the new memory be the problem?
Possibly. Remove the memory and see if the problem persists. Reseat the memory module into the socket and see if that solves the problem. Try rearranging the order of the memory in the machine. Some computer power supplies don't output enough power (or other components may pull too much power), either of which can deprive the memory bus of the appropriate amount of power. If the problem persists, try the module(s) in the system alone. If the problem goes away, it could be a compatibility issue with the existing memory. If this occurs, or the problem persists, please contact us for further assistance.

5) I need help installing memory into my machine. I cannot find the owner's manual, I cannot locate the manual on the manufacturer's website and you don't have the manual available on your website. What can I do?
Most computers have a similar memory installation procedure - notebooks and desktops alike. Notebook computers usually have a compartment located on the bottom of the unit where the memory is installed. After unplugging your computer from its power source, check the bottom of the machine for a small door a bit larger than the memory module. If you can remove the case from the outside of the desktop computer, the memory sockets are normally located near the location where the internal ribbon cables connect to the motherboard. If you need further assistance, please contact us or give us a call so we may walk you through the installation process.

6) I have a machine with RAMBUS memory. I have a single module and a continuity module installed. Can I install a larger module in the continuity slot or must it match what I already have installed?
Unless your computer's owner's manual says that is a valid configuration, you cannot install mismatched memory modules into the computer.

7) I have a machine with RAMBUS memory. I have a matched pair installed and two continuity modules installed in the other slots. Can I install a single module or do they have to be installed in pairs?
No. RAMBUS based systems with memory installed in pairs must always have the memory installed in pairs.

8) The notches on my memory module don't line up with the socket. Did I get the wrong item?
MEMORY MODULES INSERTED BACKWARDS WILL SERIOUSLY DAMAGE THE MOTHERBOARD AND MEMORY. If the notches along the edge with the gold connectors are off, then you probably have an incorrect module. Make sure you are orienting the memory module correctly to the socket. Check to make sure you are inserting the memory into the correct socket. If the notches along the sides are not lining up, the module is probably not fully seated. Notebook memory should be inserted into the socket until the gold leads fully disappear into the socket before pushing it down into the support arms. Desktop DIMM modules should be pushed straight into the socket until the arms on the side move into place and lock on their own. Desktop SIMM modules will only fit into the socket in one direction and will not properly latch into place unless properly oriented.

9) Is it normal for my computer to take longer to boot up after I install additional memory?
Yes, but no more than a second or two longer. The computer has to address the new memory installed, which can take a short time longer, depending on how much new memory was installed. If it is taking considerably longer, remove and reseat the memory module. On a Macintosh, try resetting the PRAM. If you continue to experience slow start times, please contact us.

10) If my computer doesn't recognize the memory I installed, is there anything I have to do to tell the computer that it is installed?
No. RAM is a basic system component and you will not have to do anything to tell the computer the RAM is installed. First, reseat the memory. Check to make sure you have the correct module for your computer. Try reordering the memory in the sockets. On a Macintosh, try resetting the PRAM. If you need further assistance, please contact us.
