Can I install DDR2 PC2 -6400 in place of DDR2 PC2 5400? Tags: Memory DDR2 RAM Memory Upgrade Last response: June 24, 2012 10:27 PM in Memory Share Anonymous a b } Memory April 4, 2012 11:48:59 PM HI all I have been posed a problem with a memory upgrade, I have a 1GB strip of DDR 2 PC2 6400 ram that if possible will replace 512mb of DDR2 pc2 5400 ram. I am aware that I could not run the two strips together, however I am not sure if the increase would cause problems. The Laptop is an "LG M1 express dual laptop" and as I am aware the 512mb ram is original. would any one know if this was possible or would it cause problems ?
