RAM Upgrading - Different Speeds
Hi,
My collegue and I are both having a disagreement regarding RAM.
I have a laptop with 1GB of RAM - I have bought a 2GB RAM module as well.
1GB 333MHz
2GB 667MHz
I personally think that as the 1GB would bring both modules down to 333MHz that we may as well take the 1GB stick out, so we have the following:
2GB running at 667MHz
Rather than:
3GB running at 333MHz
Can you guys please give us your input as I'd really like to prove him wrong!
Cheers,

the speed will be as the lowest speed (MHz) is, in this case 333 MHz

Yes - so would you recommend 2GB 667MHz or 3GB 333MHz?
What is the FSB speed of the systemboard? If the laptop was provided with RAM already running at the fastest speed the board can handle then your 2GB stick won't run faster than 333 MHz anyway.

The FSB is 667MHz.
Out of principal, which is best?
3GB of RAM running at 333MHz
or 2GB of RAM running at 667MHz?

2GB running at twice the speed as 3GB would be the better choice, in my opinion. Even though it isn't a processor, you can think of it that way when it comes to speed. Which is better a single processor running at 3 Ghz or a dual core running at 2 Ghz?

ok 1 for, 1 against...anyone else?
I won't speak about technical stuff as the other comments were good and complete.
But on my personnal experience I wouldn't mix RAM with different speed.
Some laptop have trouble to manage mix of speed and some even had blue screens and unexpected reboot.
In your case I would prefer to keep 2 GO and losing 1GO that having an unstable laptop.

It's not a question of "for" or "against". To determine which is better, you need to confirm whether or not the higher speed module actually runs faster; whether the chipset supports dual channel; and finally whether your particular set mix of applications is generating a significant number of page faults with only 2GB installed. I outlined how to do all that above.
Gary and I are essentially in agreement, so I don't see how the count is "1 for, 1 against". You might also consider how many questions have been answered by each "expert" - opinions are not always equal, like votes.
