1GB Kingston only shows 512MB

Hello. I have a problem with RAM. i had before 512mb(2x256mb) and when i put 1gb kingston ddr400 and now only shows total 1GB.. What could it be ?

 

Please provide the make and model number of your motherboard and the make and type of the new Ram you are trying to use.

 

Motherboard Name MSI KT4AV (MS-6712)

and RAM

Memory Module Properties
Module Name Kingston K
Serial Number 90305D39h (962408592)
Manufacture Date Week 21 / 2005
Module Size 512 MB (2 ranks, 4 banks)
Module Type Unbuffered
Memory Type DDR SDRAM
Memory Speed PC3200 (200 MHz)
Module Width 64 bit
Module Voltage SSTL 2.5
Error Detection Method None
Refresh Rate Reduced (7.8 us), Self-Refresh

 

Not my area of expertise but from pcupgrade.co.uk

This would imply that each slot can only use 2 banks, hence 2 of your 4 are missing.

 

Thanks. Any solutions?

 

Go to your supplier and try to exchange for the correct type of memory (nb your motherboard supports a maximum of 1GB per slot).

Crucial is a great place to start when thinking about upgrading your computer's memory.

Short of exchanging the stick or living with 512Mb there's nothing you can do.
