hello.
i have:
PC Specs:
- Intel Core i7 2700K 3,50 GHz BOX @ 4,20 GHz
- Asus P8Z77-V PRO
- Kingston HyperX DDR3 2x 4GB 1866 MHz XMP CL9 Genesis
- EVGA GeForce GTX 980 TI 6GB SuperClocked ACX

i need more ram. to be precise double that.

considering to buy only the one of this four sets:
- HyperX DDR3 2x 8GB 1866 MHz Cl9 XMP Savage
- HyperX DDR3 2x 8GB 2133MHz XMP CL11 Savage
- HyperX DDR3 2x 8GB 2400MHz XMP CL11 Savage
- HyperX DDR3 4x 8GB 1600MHz CL9 XMP Savage (i know its 32, not 16)

could someone please tell me, what choice will be better?
is there much difference between CL 9 and CL11 or even between 1866 MHz and 2133 MHz?
i think first option will be best, cause i have CL9 and XMP.
but notice please that i have OC my CPU to 4.2 GHz stable and dont know if i have to lower this value, or if i buy 2133 i can higher this value to 4.5 GHz for example.

it has to be kingstone, low profile ram, cause i have noctua nh - 14 d cooling system!

Hello Yawoor

It's not recommended to add/mix ram kits so what ever ram kit you go with set your current ram kit aside. I would choose the 2400Mhz kit although the 1866MHz kit with cl9 timings could be a good choice too.

If you're just gaming 16GB is plenty.

im selling old and buy new one. such retarded im not 😄
but the point is
which one will be faster ?

the 2400mhz.

the higher mhz the faster ram is.
BUT all over 1600mhz is considering OC, so it all comes down to what the mobo and cpu supports.

the more ram and higher mhz you have the more strain you put on the cpu memory controller witch is located on the cpu.

RAM HELP - need advice for existing gear
