CPU/Ram Question

[HectiKCookiE]

I'm planning on buying a X99 Xeon (E5-2620 V3) but it only support DDR4 1600/1866 what happens if i try to use 2400 ram?

It won't clock as high?

DDR4 starts off at 2133. I'm running 2666/2800 in my X99 machine.

but will it still post or just give me a ram error code?

yes i know this is my problem

I think it should work because the 4790k lists max supported memory speed at 1600 but it's well known that it can uses well above that. I think it's just down to the board.

The frequency of the Ram doesnt matter for the system to work. If the frequency is lower as the clockspeed recommended, it will run at a lower clockspeed as recommended. if it runs at a higher clockspeed it will be clocked down automatically, but you'd have a more stable overcklock if you overclock your RAM together with your CPU

thats it

lmao no - if it uses DDR4 and DDR4 starts as 2133, it will work just fine. They put wuss ram speed specs on the CPU so that they're not liable for a poorly binned chip. My 5820K handles 2800 just fine.
