Crucial/Micron DDR - ECC or not?

Well, here it goes.
I'm running an ABIT KG7-RAID with a T-Bird 1.4. 512MB Kingston ECC-Registed memory. Looking at the Crucial PC2100 512 module for it's stability & overclock ability. Does it matter if I use the ECC/Registered memory module? Will I get better performance with the unbuffered memory?

ECC RAM is slower then normal RAM
it is not made for speed, but rather stability, and reliability.
You may have problems running ECC memory with non-ECC memory... either way you will have to disable error correction in your BIOS once you have a stick of non-ECC in your rig.

Personaly i would stay away from ECC RAM as it is more $$$ and a tad bit slower.... That is unless you really need ECC, but if you dont... dont waste your time with it.

I asked Crucial about 512 MB DDR (I have a message on this board waiting for an answer).

Crucial replied that there are compatibility issues with 512 MB ECC and ABIT boards. I specifically asked about KR7A so you might want to send them an email. They replied within the day on my question.

If you OC, I suggest non ECC/Unbuffered.

ECC isn't really meant for overclocking, as was said, it is made for stability and reliability at stock speeds. Unless your running a serious server there is no need for it, especially in a home box. I wouldn't recommend mixing the two if you plan to overclock, I doubt you'll get very far.

I think its the other way around, you can run regular memory with ECC on in the BIOS but you have to turn it on with ECC RAM. I know that sounds backward but that's what I read.

I wouldnt recommend ECC either. As far using the Abit KG7, if you will fill all three slots with memory, you will need registered ram, so plan ahead.
