I need someone to clarify something about RAM for me.

Go to solution Solved by Hieb,

So I have a doubt here:

 

If I buy a pair of memory modules and it says the frequency is 1600 MHz does that mean that both run at 1600 MHz or does it mean  that they each run at 800 MHz and they sum up to be 1600 MHz?

 

 

 

P.D: Sorry if the question sounds stupid, it's just to make sure.

 

The internal rate is 800MHz, but with DDR (double data rate) its effective speed is 1600MHz.

When you run in dual-channel, the effective speed is 3200MHz.

DDR = double data rate ,so they run at 800mhz internally but have an affective speed of 1600

Hi Mcmacker4,

 

It doesn't sound stupid, i asked the same question a while back. Each module will run at 1600 MHz, just don't forget you have to change the profile of the kit in the BIOS to make sure they run at the right speed or you might not be getting the performance you pay for.

 

Hope this helps

Can you link the RAM modules in question?

It means that each memory module is rated to run up to 1600MHz.

This is the RAM I bought, they're Kinston HyperX Fury 2x8GB running at 1600MHz (the website is in spanish).

The thing is... CPU-Z says the DRAM Frequency (it's a screenshot of CPU-Z) is 799.6MHz and that's what made me think.

Also in the bios, as far as I know, the frequency is set to auto.

Most likely when you plug it in it will run at 1333 (for some reason a lot of 1600hz memory does this) and you have to set it to 1600. I had to do this with mine. Tried xmp but my mobo doesn't have any profiles for 1600hz.

 

It should be fine.

The rated speed of the sticks are the same as written on their box. Frequencies do not add up.
