I have a total of 1gb of ram. Two sticks of 512. But for some reason my computer is recognizing only 512 mb. Meaning each stick is only showing up as 256mb. What could the problem be and how can i fix it?

Is this an older computer? It may not support that much memory, if that's the case then the only way to fix it would be to get a different motherboard. Look in the BIOS to see if you have an option to support more RAM.

It's more likely that only one stick is being recognized, not half of each. If the second module is a result of an upgrade, I would recheck the clock speed or specifications (like pc3200) of each. I would go into CMOS setup and see what the clock multiplier for memory controller is and ensure that the module with lowest clock speed is accommodated for. The entire bank of memory should run at the speed of the slowest module. Are both modules DDR, DDR2, one channel, two channel, EEC, buffered, unbuffered, etc.... of all the types aforementioned, not only must both modules be the same, but the system chipset and/or processor must support it.
If this is a new system, I would inform the seller that they gave you a bad 512 module and claim whatever warranty you have.
If the system has been running with 1024 for some time now, and this just happened, you have either a bad module or port. Use only one stick in a port and boot the system. If it works or if it doesn't, move it to the other port to test the port. If it worked both times, there is no bad port. If it didn't, you have a bad module.

Some computers have problems with recognizing 'high density' RAM and may only show part of the installed. This might be fixable with low density RAM (more expensive).
1st check whether your motherboard recognizes either and quantity.

maybe someone bought and swapped the stickers and returned them, then you got them. take them back and hope for the best. also make sure they are not different speeds. also, try them individually to make sure they are both 256. also make sure your motherboard supports the ram you are putting in.
