Memory does not add up! 3

[honeybrown]

I have had 512mb of memory added to my quantex pent.3 computer. It only shows I have 384mb of memory. I have 3 memory slots and 256mb of memory in 2 slots. Reading the book that came with my comp. I was told I could hold 512mb of memory. How can I get the full 512mb?

Hi,
There can be a number of possibilities for this.
1. Bad Memory.
2. A bad memory slot-try changing the slots.
3. Perhaps its needs to be set up as 256-128-128(check the manual to see how it needs to be set up.
Where are u being told that there is only 384-in the BIOS or in the operating system itself?

To add to kippy13's notes:

. A lot of PC133/100 memory chips will only report half their true density. If your motherboard uses PC100 RAM, return what you bought and ask for true PC100 modules. I am sure the package said it was PC100 compatible, but in many motherboards it is simply not. Be sure to do this soon, as PC100 is getting hard to find. Look at your original memory modules: what you want to buy in higher density is modules with chips on both sides of the circuit board rather than just one side.

. Memory slots themselves can be tricky. It might be, as kippy mentioned above, that you need to use slots #1 and #3, or some other variation. It might also be true that if slot #1 has 256, you need to populate #2 and #3 with ram densities no higher than 128 in order to reach 512 total.

Perhaps your missing memory is being used as shared memory on your video board. My system's BIOS allows me to set the memory for video up to like 64 meg. When I check the memory on my system by right clicking My Computer then Properties. It always shows less memory than I actually have. Also, try going into your System BIOS to check the total memory installed on the system. Entering into BIOS varies from system to system, but on my system I have to press the Delete key.
