ECC Ram?

[rwest]

My sister-inlaw's computer wants more ram. Her MOBO supports ECC sdram. ECC is currently almost twice cheaper than non ECC. It is to my understanding that the ECC ram is slower and really only needed for servers. For about the same amount of money I can buy 2 stix of 128mb sdram non ECC, or two stix of 256mb ECC sdram. She's running WIN 2000. Which is the better choice?

It's a family computer, 3D games, internet, and word programs.

In order for the system to take advantage of ECC type memory, the motherboard has to support it. Meaning that CPU, Chipset and BIOS on the motherboard all must support use of ECC memory modules or "you're just spinning your wheels" as the saying goes!

Yes, ECC memory is slower but the advantage is that it lessens the probability of data errors or corruption. Again, you must make sure that your sister-in-law's system will support use of ECC type memory. By the way, you cannot mixed ECC type memory modules with Unbuffered type Memory modules.

Thanks Iptech,
Some of that I didn't know. I do know her PC will support ECC. What I'd like to know is how much slower is ECC. While 512mb is twice the amount of memory than 256mb, I'm wanting to know if 256mb of non ECC is better than 512mb ECC. Speed related to Quality.

A typical user won't notice any difference in performance.

Then it stands to reason for the typical user that:

1.512mb ECC is actually the better choice for the same amount of money.

and:

2.By increasing the size and going with ECC you get more stable ram without loss to speed.

Correct?

Correct.
