What is the difference between unbuffered and registered memory

Only slightly, a few FPS. It will still run okay, just not optimal. Dual channel is better, but single channel will work fine. You may not even notice the drop in performance. If you have a third stick, it would go into Slot 3, which will actually be between Slot 1 and Slot 2.

For virtualization environments where memory, and memory bandwidth is key to achieving high consolidation and density metrics, Registered ECC memory is generally the way to go. In this article hopefully one can get a conceptual view of the difference between the unbuffered ECC memory and registered ECC memory to help inform selection decisions. This was not an overly technical article because memory modules tend to be items that people order with or add to their systems and do little work on until they need more memory.

There are other considerations like performance that come into play. Nils-H, The reason to go registered boils down to capacity and reliability. Speed is often the same, but can a negligibly slower when using registered memory. The main issue with having a large number of memory chips connected to a memory controller whether in a chipset or in the CPU is the amount of electrical loading.

Each chip takes a bit of electrical current from the memory controller affects the impedance memory bus. Digitally, registered and unregistered look almost the same to the memory controller, but electrically, registered memory looks like a single chip rather than a series of chips. This improvement in electrical load also improves stability and thus reliability. ECC will protect from random errors so reliability is less of a consideration when choosing between the two.

Is there any explanation for this? MagnOx Thats because Dell servers are not worth a shit, they want to make things so you have to use thier hardware and software in them and non else….. Only Dell would use un buffered in a server …What brain child at Dell came up with that? Use it for a boat anchor.. T is old school dump it….

I currently use 4xMB unbuffered-ECC, but wish to install some cheaply available ebay ecc-registered before I upgrade to a new system. Not a Dell fan but your statement was completely unfounded. Therefore, at the time of execution, the programs are loaded into RAM. The capacity of the RAM is a considerable factor in determining the performance of the system.

SRAM is a fast memory built using flip flops. It is also known as registered memory. This memory helps to place a less electrical load on the memory controller. It allows a single system to remain stable without using more memory modules than in a usual system.
