Short checklist for that builds on the replies from , , and but avoids risky steps up front.

First, check for an OS-level limit that can make installed RAM appear much smaller. Open the System Configuration tool (Run → msconfig) → Boot tab → Advanced Options and make sure “Maximum memory” is not checked (leave it blank). Also run msinfo32 (System Information) and, if available, Task Manager / Resource Monitor to see if a large amount is shown as “Hardware reserved” or otherwise unavailable.

If software settings look normal, isolate hardware/firmware without flashing anything. Power down, unplug, discharge the system, then:

  • Test each module alone in the primary DIMM slot (one stick at a time).
  • Try the known-good 512MB stick in every slot to rule out a bad slot.
  • Reset CMOS / load BIOS defaults (use the jumper or remove the battery for a minute) to clear any odd firmware settings.

Run a bootable memory tester (for example, memtest86) from USB/CD to detect bad DIMMs or incompatibilities. If the motherboard firmware/BIOS lists only 512MB but the modules are good, the board may not support those DIMMs or the modules could be incompatible (density, registered vs unbuffered, etc.). Integrated video or large reserved regions can also reduce usable RAM — check onboard VGA/shared memory settings in BIOS.

Do not flash the BIOS until these steps are done; as suggested it can help, but as warned it carries risk. If the problem persists, post the exact motherboard make/model, BIOS version and the exact RAM part numbers so others can check compatibility.

You are going to give us more information. Give us a full system spec.

the motherboard model number and brand/make is most important. You motherboard may not support anymore.

Do you notice the amount of RAM during POST? (you may have to press something like ESC or tab as soon as you turn your pc on)

sometimes doing a bios flash helps. Go to your motherboard/manufacturer and download and install the latest bios update.

i would hold off on that for now ,do as Xlphos says first ,flash as a last resort because if you flash wrong you will be looking for new board or bios chip

Are You using 32bit OS and is it the second ram you are installing then in 32 bit os there are limitations in detecting ram, if your bios detects the rams or ram if you have only one then there is a problem.

if all the things in bios is correct, are u using a 64bit os if not, change to it
