Ram High Speed (DDR4)

Recommended Posts

Posted · Original PosterOP

I need somebody to explain to me how it could be possible to take advantage of 4000 MHz ddr4 RAM in an actual working system or build ?!?

 

I know a lot of Motherboards supports 4000 and above but when you look at the Specs of the CPU Intel or AMD  brand it does not support that speed! 

e.g. i9 9900k = 2666  or     Threadripper or ryzen 7 =2933 , I couldnt find any CPU that support even the 3200 MHz!!

 

my understanding is that the 3 components RAM &CPU & Motherboard  should support the frequency

so if the motherboard supports that high ram speed and the CPU does not it will work at a lower speed like 2666 or 2400 or whatever the value may be

 

I hope you get my point exactly ?

the ram is installed in the board and they are compatible but when it comes to the ram to interact with the processor at maximum Speed and the ram manufacturer make 4000 or 3200 MHZ module but the CPU specs lower memory bandwidth 2666 , what is the benefit of getting high speed ram such as hyper x predator 3200 kit or 4000 ??????

how would the system as a whole reach that level of speed ?

that's what we call overclocking....?

Google XMP or DOCP.

 

It's how a motherboard overclocks memory to the speeds that are supported by the manufacturer of the RAM (listed as RAM Speed).

overclocking the CPU or the Ram ?

 

could you please link me an article about this matter ?

Overclocking is the general term.  For RAM, CPU, GPU, any pc part really.

 

Easy enough to hit Youtube and search for them.
