      @connorsoliver said in Understanding PC Memory - CompTIA A+ 220-901 220-902 Video Training by Prof. Messer: 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 said in DELL PowerEdge T410 - Memory Configuration Issues: @PhlipElder said in DELL PowerEdge T410 - Memory Configuration Issues: As a rule, the primary slot in each channel should be populated. So, 4 sticks per CPU. Make sure Memory RAS settings are default and not stripe or mirror. That may be part of the problem. Make sure the sticks are in the primary slot for each channel which is usually a different colour than the secondary and furthest from the CPU. T410 is old 5500 series chipset which is triple channel, so I don't think you gain anything with 4 per CPU. Yeah, that era was three or six.

      @BRRABill said in Linux: Using Top: @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?

      Thank you, I'll investigate from here.

      @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'.
