im building a system and im looking at memory at newegg. what is the difference between 32X64 and 32X72?? price difference is $13.00 the 32X72 is more expensive.

1. CRUCIAL MICRON 256MB 32x64 PC 2100 DDR RAM - OEM 184-Pin, CL=2.5-Unbuffered 2.5V,6-Layers CT3264Z265.16T. Requires DDR supported Motherboard - Lifetime Warranty. OEM

2. CRUCIAL MICRON 256MB 32x72 PC 2100 DDR RAM - OEM 184-Pin, CL=2.5-Unbuffered 2.5V, ECC, 6-Layers. Requires DDR supported Motherboard - Lifetime Warranty. OEM/ NOT RETAIL BOX

I will be putting it in a Epox 8K7a+ MOBO.

The 32x72 is error correcting modules (ECC). You have to have a mobo that supports it to use it.

Cool thanks. the prices at Crucial.com are cheaper and free shipping.

ECC is not the choice of RAM for a home system. It's mainly for network servers because ECC is Error Correcting Code RAM. It's more accurate than non-parity RAM but it's also slower because it actually checks the data for errors.

Yea i know all about ECC RAM. I wont get it for my home system but since i am in denver and closer to the sun every server in my farm has it.

Yup that's the parity chip.
