Please return the memory and request single-sided modules with the same density.This article discusses an issue where Microsoft System Information (Msinfo32.exe) tool reports incorrect Adapter RAM values under Components > Display.Īpplies to: Windows 7 Service Pack 1, Windows Server 2012 R2 Original KB number: 2495801 Symptoms 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.(This is not an error - some systems must do this to update their CMOS settings.) If you get a memory mismatch error follow the prompts to enter setup, then select save and exit.Some systems go in reverse order, so if this doesn't work, try reversing the procedure. 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).Using EDO or SDRAM in a system that does not support it will not work, often resulting in a blank screen and no POST (power on self test), or a BIOS/CMOS setup error.
FPM/EDO/SDRAM, parity/non-parity/ECC, buffered/unbuffered). Make sure that your new memory is the same type as your old memory (i.e.Remove and reinstall the modules to make sure that they are seated securely in the socket.To update your BIOS, contact your system or motherboard manufacturer and they'll direct you to where you can download the software for free. Don't worry - updating your BIOS isn't as difficult as it sounds. If your computer is older, it may need a BIOS (Basic Input Output System) update in order to work with today's technology. Make sure all cables are firmly lodged in their sockets. We get multiple calls about memory not working when the computer just needs to be plugged in! Double-check internal cables.ĭid you accidentally bump one of the wires or cables inside your computer while you were installing your modules? A loose hard drive cable can prevent your computer from booting up properly.
Make sure all your power cords are plugged in. It could be your operating system, because there's a maximum amount of memory that a Windows-based operating system (OS) can accept. The problem may not be due to your hardware. If installed properly, the clips on the side of module should snap into place on their own and a thin portion of the gold pins - 1/16th of an inch or less - should be visible (about the width of a line of pencil drawn on a piece of paper).
While this may seem like a lot of force to use on a small module, it's necessary to properly "seat" the module. Make sure the notches in your module are lined up with the keys in the slot, then press down using 20 to 30 pounds of pressure. Press harder when inserting modules into the memory slot.
