can't run ram in their full speed

For some reason, I had to enable XMP in my Gigabyte BIOS twice before it actually took.  But it did.  Otherwise, "what they said".

i have :

i3-4150

avexir 8gb of ram (2x4) 1600mhz

so when i run cpu-z i find the ram running in 800mhz

so i activate the xmp profile

Long story short: your memory is running at the right speed, if CPU-Z shows 800Mhz.

 

Long story a bit less short:

Your memory runs at 800Mhz, which is (millions) of ticks per second. Per tick it can do two transfers (which is why it is called DDR = Double Data Rate), so it is running at 1600MT/s (millions of transfers per second). Manufacturers of memory/motherboards call this 'MT/s' unit 'Mhz', thus 1600Mhz.

CPU-Z reads it out the right way, thus 800Mhz.


I apologize for the way I am. If my post seemed rude, that was not my intention. Just my ineptness in forming a nice coherent message.

DDR stantds for double data rate, so 800Mhz x 2 = 1600Mhz

thanks

There is no right or wrong... only popular opinion, political correctness, and government edict.
