      What exactly does registered memory do?

      Wikipedia has about the best explanation of this. Mostly we ignore this, IT people really don't think about registered vs non-registered memory, that's something bench people worry about or your server vendor, but not IT. CompTIA mentions it because it is a bench exam.

      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. When compared with registered memory, conventional memory is usually referred to as unbuffered memory or unregistered memory. When manufactured as a dual in-line memory module (DIMM), a registered memory module is called an RDIMM, while unregistered memory is called UDIMM or simply DIMM.

      Registered memory is often more expensive because of the lower number of units sold and additional circuitry required, so it is usually found only in applications where the need for scalability and robustness outweighs the need for a low price – for example, registered memory is usually used in servers.

      DDR2 uses a clock speed twice as high as the bus speed. So DDR2 is double the speed of DDR given the same bus. The clock that the computer provides to the RAM is the same speed. But the memory clock speed in these cases as either 1x or 2x the bus speed from the computer. So the clock speed is double.

      @pete-s how does any of this make my sense at all??? Did anyone even read any of this thread before posting???

      You say he CANT use 16gb sticks which he has CLEARLY done already and have worked but instead of giving good answers you guys pressure people to move on because the people commenting on here either can’t read or don’t know enough already...

      This is aggravating because every post about the T410 gets cut off with nonsense like this crp...

      He used 16gb sticks so remove your comment, or don’t make one and move on if you didn’t have the answer to the question you just made the question more confusing

      If you read more carefully next time, you might not become aggravated. What is supported and what works are two different things.

      Reason to move on from old hardware is because for companies IT is a business, not a hobby. Spending time on something costs money, so the potential benefit has to outweigh the cost.

      I automatically ignore Fedora and CentOS warning about that.

      I ignored it also. just pointing out the default behavior.

      @scottalanmiller

      But "respecting it" means nothing.

      In WIndows, pressing a key for a function only does that function, or nothing.

      I am taking about, for example, in top where

      m

      and

      M

      do two totally different things.

      Right, an in WIndows it always does two different things. If you keep using it in places where both do nothing, you can make ANYTHING into "not sensitive". But that logic, nearly every letter on the keyboard does the same thing - nothing. So you just told me that WIndows isn't "key sensitive". See why that makes no sense?

      @Dashrender This is only moderate density DDR3, no where near 128GB. Every color is another layer of copper. Check out his grid size for scale! 4 thousandths of an inch!

      Now consider that each trace from the chip to the pin needs to be the same length or you start to induce latency errors. That should blow your mind sufficiently 🙂

      Ran through a few things, and happened upon the uninstall / repair option.
      I ran the repair, which subsequently required a reboot (no surprising on a system service).

      Currently the system performance has increased back to 'normal'.
