i am going to by some ram for my new computer and i need DDR ram. when i go to look at it on the internet it has what seems to be regular ddr, it has ecc what ever that is, and has ecc registered. please tell me what the difference in the three are b/c the "regular ram" is a lot cheaper, but i dont know how much better the ecc etc. is

thanks

If you don't run a MP board that "requires" ECC ram or you don't run a server don't bother with ECC DDR ram it won't do anything for you.

Just buy the best "regular" DDR 2100 ram you can affoard... Like Kingston.

Which mobo? You probably can use the regular "non ECC" ram & "registered ram" is usually for Servers.

i dont have the mobo yet but im getting a Microstar MS-6380 Raid K7T266 PRO w/ 1.2Ghz tbird

u think $63 is a good deal for a 256MB ddr chip?

Ok... then with your board don't bother with ECC ram because it doesn't support it and would be a waste of money.

ECC basically is an extra bit of info on your ram which try's to correct memory errors by storing memory info on the bit of info.

Its confusing but its only for MB that supports it which yours doesn't....

Hi cracked,

The term "registered" refers to how the memory module processes signals. Registered modules contain a register that delays all information transferred to the module by one clock cycle. This type of memory is primarily used in servers and was designed for modules with 32 or more chips on them to help ensure that data is properly handled.

ECC (error correcting code) modules have an extra chip that detects if the data was correctly read or written by the memory module. If the data wasn't properly written, the extra chip will correct it in many cases (depending on the type of error). Non-ECC (also called non-parity) modules do not have this error-detecting feature.

ECC and parity are not exactly the same. Parity modules detect single-bit data errors. Error correcting code (ECC) modules detect and correct single-bit errors, and they detect and report double-bit errors.

I recommend that you spend some time in Crucial FAQ section as it will give you a nice idea about all your memory questions ...

Here are some links i though it might help you and save you time searching :

And the Crucial.com banner at the top right of this page will take you directly to the Crucial website, where you can enter your mobo manufacturer and model to get a 100% RAM compatibility gaurantee.

Yeah, what Fingers said ^ ^ ^.

That's what I did when I went to Curcial.com and looked up the price. It was the exact ram for your mobo.
