Memory Shopping, what is the difference?

[Thawk]

I was looking at memory on crucial.com and I don't know which of these to buy. I am buying two to go on a ASUS A7N8X Deluxe with a AMD Athlon XP 2600 processor.

256MB $42.99 (USD) CT3264Z335 DDR PC2700 ? CL=2.5 ? Unbuffered ? Non-parity ? 6ns ? 2.5V ? 32Meg x 64

256MB $52.99 (USD) CT3272Z335 DDR PC2700 ? CL=2.5 ? Unbuffered ? ECC ? 6ns ? 2.5V ? 32Meg x 72

Thanks!

The difference is one is ECC & one isn't.

Get the non-ECC.

Viper,
thanks for the reply and advice. What is 'ECC'?

Error checking correction (or something like that)

Basically the ECC memory is slower because it checks over the data. It's good to have for mission critical servers, but in home computers, there's no point in checking over every piece of data that goes into ram.

Less $ for faster ram = deal

What he said. Mind you, I ran four sticks of ECC in a home rig once at CAS2. Ran like a dream, and rock stable too.

That processor comes in 266 & 333 Mhz FSB versions. Your mobo supports 266, 333 & 400 I believe. You may want to look into getting PC3200 memory that runs at 400. That way if you ever decide to upgrade your processor to one with a 400Mhz FSB you won't be out buying memory all over again. In the meantime while you have the slower processor you'll be able to run your memory that has some leftover performance at more aggressive timings.

Just a snack fer thought.

edit: another confirmation of the guys above - if you don't have a specific need for ECC, stick with non-ECC / non-parity.
