It is a limitation of how memory calls are made and limits to individual memory calls per application. Most individual programs won't use more than 4GB of memory at a time. More memory won't necessarily help unless you are nearing capacity of your current memory. You would probably see better gains from utilizing dual channel rather than higher speed memory modules. As to whether either of those will help your video editing, not likely. Most likely this is a cause of how programs call or utilize memory, they just aren't optimized to use that much bandwidth.Īs to whether you should get 1866 or 1600, I would suggest 1600. Also, most benches I have seen show minimal gains past dual channel.

You should definitely see speed improvements though. You do not always operate at that rate however, so you probably won't usually see 2x/3x/4x the speed in prolonged use. When you use dual, triple or quad channel you are essentially providing enough bandwidth to move double, thrice, or 4 times that amount which gives you 128, 192, or 256 respectively. Which means it can move 64bits of data at a time. This means you have a 1066 Kit that has an Overclock setting of 1218 apparently.Ĭhannels as mentioned above deal with how much bandwidth can be used. 533 is the max speed rated for the type of RAM you are using, but it is saying there is an additional setting of 609 as well. SPD is saying what profiles are available on that RAM. So as he stated above, if it lists the current frequency at 486MHz, your actual bandwidth is 972MHz since it is running twice the data at 486MHz.

Doubling the amount of RAM you have only would in the case that you're actually utilizing close to all of your current RAM.Īnother thing to keep in mind is that if you're using Windows 7 or Vista, you have to have at least Professional or Business in order to use more than 16GB of RAM.īut to expound a little bit, DDR stands for Double Data Rate. A lot of times (at least in the past) the BIOS has to be explicitly told what settings to use in order to run high-performance memory at its advertised speed.ġ866 vs 1600 would probably not yield any noticeable increase in performance.

If basically just tells the BIOS how to setup the memory controller to be able to use the memory. The 380-457-533-609 listed by CPUz is just the profile data that the manufacturer loaded into the modules before shipping out to retailers. So 486MHz is effectively running at 972MHz. I have DDR3-1333 ram, and Speccy is reporting my system as running DDR3 665MHz, which pretty close to what it's expected to be). If you're using DDRn (where n is 1, 2, or 3), the the data frequency is double the clock frequency regardless of how many channels you have (e.g. (Note: this has almost nothing to do with your CPU being 64-bit or 32-bit). single channel is 64-bit, dual channel is 128-bit, and so on. Multi-channel just increases the how much data can be handled per transfer. You don't multiply the frequency by the number of channels.
