Is ECC Registered memory buffered?

post #1 of 6
Thread Starter 
the title is my question. is ECC Registered memory buffered memory or is it unbuffered ECC? im an idiot when it comes to server hardware. thank you.

here is the memory module in question.

The purpose of ECC Ram is to detect and correct single-bit (bit flipping) errors that occur in the memory.

ECC memory (Error Correcting Code) can detect and correct the most common kinds of internal data corruption.
The Motherboard, Memory and CPU need to support ECC to use it.

The purpose of Registered/Buffered Memory is to ease the electrical load on the memory controller (these days: IMC) when you have a lot of memory in the system (like with servers).

Registered (also called buffered) memory modules have a register between the DRAM modules and the system's memory controller. They place less electrical load on the memory controller and allow single systems to remain stable with more memory modules than they would have otherwise.
The register/buffer in between the ram modules and the IMC is located on the motherboard, so if your motherboard does not support Registered/Buffered RAM you cannot use it, and the other way round.

on my setup the IMC is built onto the CPU itself and im using a Xeon CPU for my build. just wondering the difference between ECC Registered and ECC Unregistered memory

Haha did you not read my post above?

Registered memory requires hardware on the motherboard to work. If your motherboard supports it, registered memory eases the load on the IMC for when you have large quantities of RAM.
Unregistered memory is what we have in most desktop computers (and usually also Non-ECC).

It is common to see ECC and Un/Registered/Buffered paired together with the labeling of these ram modules because they are designed for servers which are designed for the case of having lots of ECC RAM.

How much RAM are you planning on having in the system?

i dont really care if the ECC function doesnt work, all i really care about is if i can acquire more ram for far less $$$. i can get 24GB of DDR3 ECC Registered for $25 while the same amount of desktop memory costs $100. my board is a P6T but ive seen people run ECC Registered memory on it before since all i care is more ram for less money. if the ecc reg memory works like desktop memory on my board then fine by me.

Meh whatever dude, I'll leave you be and someone else can help you.
