it seems the computer may support one sided memory modules . I'm using 2 x 128mb 2 x sided modules and the Setup shows 131072K of memory . Would you think I could go ahead attempt to install Windows NT anyway ? dumb-b_m

There's no harm in trying to install Windows! I don't actually see what the problem is: does the computer only recognize a particular type of memory or is it only seeing half of it? Free PC Help forums

Your memory is reporting correctly. remember 1MB is actually 1024KB. Do the maths :-) AMD Athlon XP 1.8GHz 1GB RAM 120GB HDD SATA GeForce 4 Ti4600 128MB Nvidia nforce2 chipset w/ soundstorm Pioneer DVD/RW ABIT NF-7S Rev 2 Motherboard

If you have two 128 MB memory sticks in your board, then one of them either isn't seated correctly, or isn't working...If they were both working, you'd show 256MB, not 128 upon POST. Or maybe I misunderstood, and you're using 2 64MB modules? Soylent Green is PEOPLE!!!

Bad seated memory at this point . I had to take the memory out to take the floppy disk drive out and now the memory test shows varying amounts of memory each time the computer boots up , sometimes the full amount . The floppy light comes on twice throygh the bootup process and the number lock key stays on . Maybe the memory needs reseating again . I have the Award Bios postcodes here and will look at those , reseat the memory and make sure all the cables are in as far as they can possibly go . dumb-b_m
