ECC or non-ECC + high/low density PC133 RAM

[phuongtran]

Hi all,

I have a question for you guys.

For a 512MB PC133 RAM module

How do you know it is a ECC or non-ECC?
How do you know it is a high or low density?
What is the difference between high and low density RAM?

thank you,

"How do you know it is a ECC or non-ECC?"
It will say ECC or registered. If it doesn't its not. This is a selling factor, companies will put it all over if it is, usually.

"How do you know it is a high or low density?

If I remember correctly it has to do with the way that it is address in the system. Higher density should be faster, but not much I wouldn't worry about it (<1%). Just by good RAM.
