Running Tomb Raider with the system set to either quad-channel seems to make no difference either. And yes, more of the same in Dirt Showdown. Read on for my conclusion. Give up half your memory bandwidth just to make a smaller system with six or eight cores?
I had the same reaction myself originally. The quad-core Core iK has an 8MB cache. Could going to an 8-core Core iX show the weaknesses of cutting system memory bandwidth in half? But if I had to choose a small box where I got six cores instead of four, and my workloads benefited from the extra CPU cores?
Encoding performance Synthetic tests measuring the theoretical performance is one thing, but just where does it show up in real tasks? Adding that new memory stick will make no noticable difference to that. Does dual channel memory make a difference? The others being the Mac mini and the new Mac Pro. You can upgrade the RAM in the iMac Pro but it involves cutting sticky tap holding the display to the chassis and a fairly lengthy disassemble process to get the motherboard out.
DIMMs are seen as distinct as they receive the same data through the channel memory provided for them. Hence, when one of these channels fails, the other channel is utilized by the memory controller.
Sparing mode may also be enabled in a dual-channel memory configuration. While in saving mode, one rank acts as a spare for the others within the channel. This specific rank is inactive in case an active rank fails to work. When a failure in another rank happens, the idle rank replaces it, and its memory capacity is, then, subtracted from the overall memory capacity of the whole channel.
The failed rank goes offline, and the new one becomes active. Because this process requires replication of data, the level of redundant memory involved in a sparing mode is far less than the one provided during a mirroring mode. Hence, for critical processes, the mirroring mode is the preferable option.
Modern computers are constructed with dual-channel memory capacities. However, it can be challenging to establish this when you do not know which item to look for in your motherboard. Nevertheless, modern motherboards detect the RAM chipsets that you insert into its slots. Bear in mind, though, that you need to fill in two parallel slots first. The numberings must also be followed, filling in the slots from the lowest number to the highest.
In a motherboard that supports dual-channel memory, memory modules must be inserted in pairs. Use identical RAM chipsets, both in the capacity as well as size. For instance, for a motherboard with two slots per channel, which are labeled A0 and A1, B0 and B1, install the first two modules in slots A0 and B0.
However, when you are not sure that dual-channel memory is enabled on your computer, check the information displayed on the BIOS screen during computer boot. You can download the software CPU-z as well.
It indicates whether or not dual-channel memory is activated. Is it possible to use only one RAM stick on a motherboard configured with a dual-channel memory capacity? Of course, it is. Almost always the memory slots will be color-coded to indicate the memory channel, as shown in the picture below.
The first channel is often slots one and two, and the second channel is three and four. When installing memory in pairs make sure to install them into the same colored slot to take advantage of the dual-channel platform. As can be assumed by the names, triple-channel architecture triples the available memory bandwidth and Quad-channel architecture quadruples the memory bandwidth.
