What is the difference between ecc and registered memory

Bit flips can indicate faulty memory, but can also very occasionally be due to cosmic radiation. Registered memory is a mechanism for optimizing memory transfer to the computer by adding additional circuitry.

That doesnt tell me if they're both achieving the same thing. Improve this question. Because of the PLL and Register chips, the server memory capacitor can be made very large, it can better meet the endless requirements of the ever-increasing software for memory.

RECC has one more register. We can understand the function of the memory as a book directory. When the memory receives a read and write command, it will retrieve this directory first, and then perform read and write operations, which will greatly improve the efficiency of the server memory. The Register memory that can be used at present also has ECC function, and some motherboards require the memory to support Register.

In fact, all registered memory is ECC memory. The use of ECC memory requires the support of other computer components, such as the motherboard and cpu, and may also need to be set in the BIOS before it can be used on most server CPUs and motherboards some non-server CPUs and motherboards also support.

In addition, when purchasing ecc memory, you need to pay attention to whether it is ecc udimm or ecc rdimm or ecc lrdimm or ecc 3ds rdimm or something else. Because your computer configuration may not support some types. The data densities of the HDD push the edge where need to keep up with track integrity.

All the ones that store the data encrypted 'at rest' basically have to if going to be competently implemented. Get feral when you answer to the greatest interview in history Share your philosophy. Error correction code memory ECC memory is a type of computer data storage technique. It is more expensive than ordinary memory sticks because of its higher tech and larger capacity.

Directly connected, unbuffered RAM vs. They just have different trade-offs in terms of how many memory slots you can have. In most cases where you need as much memory as possible, that extra memory more than compensates for the RAM running at a slightly slower speed. How much depends on the drives. At use both draw more. Multiply that by Double-ish that for in use.

It can be great. Many of its more advanced features e. Sign up to join this community. The best answers are voted up and rise to the top.

Improve this question. Hennes Asking on SuperUser will get you SuperUser answer. Ask on ServerFault will get you ServerFault answer. Get my drift? The FAQ states hardware questions can be made on superuser Sry, I thought that was assumed.

Was only making mention that from the OS side there could be different considerations in how ECC is addressed because this will utlimately become a server application. Most of the time the chipset will handle ECC correction if any. You do not need to tap into those from the OS at all. Add a comment.

Improve this answer. Thank for your quick reply. But I though 16GB was kinda the limit Anyway it's strange No drawbacks on ECC here.

Are you sure that ECC is not needed??? The fact it is the defacto standard doesn't necessarily mean that it's reliable enough. And more memory CAN make your system faster, even if latency increases.
