It may not be supported.

The system memory that is reported in the System Information dialog box in Windows Vista is less than you expect if 4 GB of RAM is installed

Take a read on that.

The instances I have seen on the net about the same type of problem refer to the msconfig setting Zigsag3143 mentions. Since you say the boxes are not checked, maybe try checking the memory box and set it to a number around 3GB, reboot and see what happens. Then uncheck the box and reboot again.

All I can think is that a flag has been set to reserve the memory for some reason or something is wrong with one of your sticks. Maybe checking and unchecking the box would reset the flag.

Swapping the slots on the motherboard might help, if you can do that. Make sure the system is unplugged and ground yourself on the case before touching the memory.

Some MOBO's have a memory setting for installations. Usually it cuts the amount of memory used during an install. check your BIOS for that.

@saltgrass. Absolutely. Nice post. +rep

Still havent responded to where you are seeing the max memory and avail memory. In task manager, BIOS, etc?

If the BIOS is not detecting all 4GB at startup, you may have a hardware issue.


Have a quick read through my reply here:

Memory reserved after using nomemristrict in GTA4

Disappearing RAM during POSTing is not really a good sign

That would depend on whether the RAM itself is actually faulty or not.

If each individual stick of RAM passes memtest, then replacement RAM is unlikely to help. However, if one of the sticks are faulty, then yes it probably would.

Does your BIOS allow you to manually input all the correct and rated timings and voltages for your RAM?


I'd suggest trying to eliminate the RAM as a problem first, before rushing out to replace it only to discover the problem is elsewhere.

Most bioses also have an option for a quick boot or an extended one. During an extended one, the memory is tested and the total amount shown. If that number is different from the Windows one, it might be a clue to the problem.
