Hello Members,

I have a Sony Vaio Computer

• 1.5 GHz Intel Pentium 4 Processor
• 128 MB RAM Rambus Installed - Max 512 MB
• 60 GB Hard Drive
* O/S ME

I want to add more memory. so I purchased
( 2 ) 256 MB Rambus sticks, so I removed the old 64 MB sticks from slot 1 from left to right and slot 3 and add the new 256 MB to slot 1 and 3.
slot 2 and 4 have the dummy sticks installed.
when I try to restart the computer, I don't hear the one beep when the computer restarts up and the monitor screen doesn't turn on. anybody know what I'm doing wrong?

also I noticed on the new memory sticks from samsung that I purchased form a memory store. on one of the sticks it has a silver cover plate on both sides, is this the ECC? and the other one it only has the silver cover plate on one side only. I think this is the Non-Ecc? If this is correct that maybe the problem because I believe they can't be mixed. On the old 64mb sticks that sre being replaced it only has one silver cover plate.

thanks for any help...
