Thanks for verifying and creating more confidence for the OP.

You double it and you have the speed you get in the bios.

Simple, no?


That is not how it works.  Arakasi explained that above.  Running dual-channel just gives you more bandwidth, it does nothing to the frequency at which the RAM operates.

Here you go

http://www.hardwaresecrets.com/printpage/Everything-You-Need-to-Know-About-the-Dual-Triple-and-Quad-Channel-Memory-Architectures/133

Yes you are running at 1866

Your board is capable of quad channel, I would take advantage! As you double your memory bandwidth to 256 bits, while-as 2 Sticks of ram runs at only 128 Bits of bandwidth.

Its all in that article above.

Whether 1, 2 or 3 sticks or ram, CPU Z as well as as other software report it at half the speed. So whatever speed CPU Z shows multiply it by 2 to get your actual frequency.

Hey guys
I'm running my ram in tripple channel and in cpuz it shows 633
So what speed mine is running at?

@bmxmandan If you have 4 sticks installed already, and don't see "quad" channel in CPU-Z like below, then I would refer to the manual for your RIVE and re-order the RAM sticks, you want two on each side of the CPU socket, if it's anything like my x79-WS board.

That would be 1266Mhz.  That goes back to the whole DDR thing again.

Hello,

Again that is not the way it works. It just appears that every time we look at cpu-z , were looking at memory that is DDR. applaud.gif
Try looking at cpu-z with SD ram installed. Will be an old clunker probably. tongue.gif

Just to avoid confusion:

-Amount of channels and frequency are two completely different things

-DDR = Double Data Rate. To get the frequency of your RAM simple multiply the DRAM frequency seen in the CPU-Z memory tab with 2.

-The amount of Channels affects the bandwidth (=amount of data that can be read/written on your memory each second) of your memory. Dual channel memory will have double the bandwidth of single channel memory.

However more channels wont necessarily increase performance. Beyond 2 channels the bottleneck will in most cases move to the CPU, because it can't process the data as fast as the RAM delivers it to the CPU. That's why only the extreme CPU mobos have quad channels, anything higher than dual channel is pretty useless for quad core processors.
