Acer Aspire 1640

I am going to upgrade memory to 2GB. I have 2X1GB DDR2 667 MHZ memory sticks. Unfortunately the FSB is 533MHZ. My question is will the new memory sticks will perform with lower speed or it will not function at all.
Crucial scan described the system will not take dual channel but the sticker on the laptop shows that it will support dual channel. CPUZ also described the fitted memories as dual.

I am not sure about this. Can anybody through some light on the situation please.

Thanks for your quick response. I was thinking to install these sticks but had second thought to seek some expert advice.
Will do it now and post back.

The exercise was not fruitfull. I installed the memory sticks. No beeps. Windows loaded but after a minute lappy froze. I tried to reboot 3 times the same poblem. BOIS was showing the total mem as 2GB but have to reinstall the old sticks which performed perfacl.
