What's better performance wise? 1.5gb/533mhz or 1gb/667mhz for a notebook computer?

Question

I have a notebook and plan on buying a 1gb of pc5300 667mhz memory. Is it better to remove one of my 512mb 533mhz sticks and run the laptop at 1.5gb@533(the lower & limiting speed) or pull both 512's and run the single 663 at higher speed but at only 1gb of memory? Is there a big difference between 533 vs. 667?

I have a dell e1705 that came with 553 but can run 667. I have 2 512s of 553, but want to eventually replace bith with 2 1gbs of 667 :D

Answer 1

I am going to say that 1.5ghz system, as it is 50% more powerful then the 1ghz system. Memory will play a large part of overall system preformance.

Answer 2

I would opt for 1GB/667 mhz, although it has a smaller amount of RAM, that can easily be upgraded in the future. Plus I dont think you'll notice much performance between the two, although 1.5GB is greater than 1GB, you get a better bus speed with the latter option.

Answer 3

I'd use BOTH strips at the slower speed. You gain more benefit by having more memory then you do by minor changes in the clocking speeds. Make sure you put the slower memory chip in BANK0 (first slot) to prevent BLUE screen due to bios clock syncronization.

Answer 4

This isn't being very specific. more front side bus is always better then less. Clock speed (1.5Ghz,etc) has little to do with the actual performance these days.
