Troubleshooting Tips

Before you do anything, you have to take these precautions: Make sure that you are working in a static safe environment. Remove any plastic bags or papers from your work space. Touch an unpainted metal part of your case before touching your new modules or any other components in your system.   Are you having trouble installing your new memory? Don't worry, Hopefully you can fix it going through the following steps.   1. Remove and reinstall the modules to make sure that they are seated securely in the socket. 2. Sometimes the connections are not set properly. All you have to do is press the memory in a bit hard. Please be careful. Just press it hard, but don't knock on it as it may damage your motherboard. Make sure the notches in your module are lined up with the keys in the slot, and then press down hard. It can take 20 to 30 pounds of pressure to install a module. The clips on the side of module should snap into place on their own. If you have to move the clips into place by hand, your module isn't installed properly. 3. If that doesn't work, please try cleaning the connectors. You can do that by rubbing nail polish remover across the connectors with a soft cloth. This removes possible carbon deposits from the connectors. You can try pushing the memory in firmly making sure the clips snap in automatically. Make sure that your new memory is the same type as your old memory (Non-ECC/ECC, Unbuffered/Buffered/Fully Buffered (FB), High Density/Low Density, FPM/EDO/SDRAM). Using incompatible memory would often result in blank screen and no power on self test or a BIOS/CMOS error. 4. Fill your slots starting with the largest density and working to the smallest (put the largest module in slot 0, and the second largest in slot 1, and so on). Some systems go in reverse order, so if this doesn't work, try reversing the procedure. If you get a memory mismatch error follow the prompts to enter setup, then select save and exit. (This is not an error — some systems must do this to update their CMOS settings.) 5. If your system is only reading half of the new module's memory, and the module has chips on both sides, then your system probably will only recognize single-banked or single-sided modules. Please return the memory and request single-sided modules with the same density. 6. Update your BIOS. If your computer is a little bit older, it may need a BIOS (Basic Input Output System) update in order to work with today's technology. Don't worry — updating your BIOS isn't as difficult as it sounds. You just need to contact your system or motherboard manufacturer. If you need an update, they'll probably point you to a Web site where you can download the new software for free. It's usually very easy. 7. Last, but not the least, the problem may be with your operating system. Some versions of Windows® do not recognize memories above a certain limited, especially if you are using a 32 bit Windows®.
