ECC vs. non-ECC memory

Yes, I read the memory FAQ. Very Good!

However, what I would like to know-- can ECC memory be used in place of non-ECC memory? Or does ECC require specific support for it by the motherboard or what ever? I have a Chaintech VFN4 mb with 2x512 Kingston value RAM. If I go to 2x1024 I'd like to know if I can go the ECC route. But then the question arises: is ECC memory worth it?

Overclocking is not in my plans.

in an older PC I used a couple of 512MB ECC ram (SDRAM lol)
in a normal mobo (no ecc) and they worked fine...

dont know about new mobos however...
maybe it depends on each mobo...

ECC is mainly used for servers and other mission critical applications that requires extra security and stability. Non-ECC are for regular use like for gaming and home pc. ECC rams are a bit slower since it works with extra steps thats prevents errors and are a bit expensive in most cases. You can use both in a Non-ECC motherboard, but you have to use an ECC supported motherboard to use the ECC feature of the ECC rams.

ECC requires support from the motherboard. If your looking into building a gaming rig, don't buy ECC ram. It generally had higher latencies than non-ecc. ECC (error-correction code) was developed for servers and workstations and have no benefit in desktop PCs.

I have seen ECC ram cause problems in non-supported mobos... and infact, many manuals now states: "supports 2/4 sticks of non-ecc DDR1(2)".

Ah. So ECC does require motherboard support to have ECC actually work.

Well, that ends that idea.

Thanks, folks.

Also, almost all available ECC RAM is also "registered". Registered RAM will not work on typical MBs -- they require "unbuffered" RAM.
