DDR3 RAM wrong?

Hello guys, what's going on?

I need your help, and (probably) somebody can help me :)

 

I have on my system 4GB DDR3 RAM which should run on 1333Mhz, but Piriform Speccy says something different.

My RAM are running (this is what Speccy says) at 665MHz, what you can see on the screenshot, and my question is, is that normal or does the RAM doesn't run at full speed when it's not under heavy load. Thanks in the advance for answers :D

It's suppose to be like this.

Because it's dual channel (double is one of the D's in DDR) it kinda means this 1333MHz is achieved with both sticks. Something like that.. I dont remember fully.

Either way, this is correct

Yes that's normal.  Fear not, it is running at full speed, it just reports like that.  You will also see DDR3 1600 shown as 800  for the same reason

Solve your own audio issues  |  First Steps with RPi 3  |  Humidity & Condensation  |  Sleep & Hibernation  |  Overclocking RAM  |  Making Backups  |  Displays  |  4K / 8K / 16K / etc.  |  Do I need 80+ Platinum?

If you can read this you're using the wrong theme.  You can change it at the bottom.

This is incorrect. RAM speed is double because it's double data rate. Not splitting up speed per stick.

Yeah, I knew I was not 100% right..
