problem about ram
 

dear sir,

i have an asemble machine with mercury motherboard, intel p III 850 Mhz, and 256 mb of ram. my problem is my ram memory is shown 192 mb instead of 25 mb. i change the slote but problem remains. then i test individual ram, and one of them shows 64 mb instead of 128 mb. what should i do to fix this problem?
thanking you

It depends on what type of RAM you are using. I'm assuming PC100 or PC 133 SDRAM. Are they Single or double sided. The double sided or highest RAM is put in slot 1 (nearest to the CPU Processor) Check your Motherboard specs if you can for the configurations. If you have two sticks of 128mb = 256mb Windows will use some of that Memory for Graphics, so you will never see the full 256mb RAM in a System view.....192mb RAM sounds about right. You can always change how much Windows uses for Graphics in the BIOS, but I wouldn't set it below 32mb.
Hope this answers your question

Raja, try to find your motherboard manual as sometimes in a lot of boards it depends on single or double sided ram and which slots they go into,also check BIOS for total RAM ,If this says 2oo-256 then windows is not recognising 1 stick fully.check that they both have the ESPD chip on the top ,if 1 hasn't this can cause conflict.A good site for links and info is http://www.motherboards.org/tools/moboidtools.html.
