Corsair 32gb dominator platinum ddr3 2400 Mhz with Intel i7 4960x and Asrock x79 extreme 11

post #1 of 5
Thread Starter 
I am planning my build, and want to make it .... well, beasty smile.gif

Planning on using 32 gigs of RAM : Corsair 32GB Dominator Platinum DDR3 2400 Mhz,
with a high-end motherboard: ASRock x79 Extreme 11,
with an Intel i7 4960x extreme processor.


Intel says the processor supports the following memory:
DDR3-1066, DDR3-1333, DDR3-1600, DDR3-1866
ASRock says the motherboard supports the following memory:
- Supports DDR3 2500+(OC)/2133(OC)/1866(OC)/1600/1333/1066 non-ECC, un-buffered memory
- Supports DDR3 ECC, un-buffered memory with Intel® Workstation 1S Xeon® processors E5 16xx/26xx/46xx series in socket LGA 2011

So the question is, can it be done, and if yes, how?

It depends on the IMC on your processor. The motherboard may support 2400+MHz speeds, but the IMC has to be able to support the higher speeds as well. It's mostly chance whether or not the IMC will go higher than the rated speed. Only way to find out it to get the components, assemble the PC and test it.

Great, but whats IMC? Also the equipment is kinda expensive, so I'd rather not jump in buying them without knowing they will work together.

IMC = integrated memory controller

This is what used to be part of the northbridge before it was placed on-die in the CPU, it reads and writes the data from and to the RAM. Since it's in the CPU the quality will vary, meaning some CPU's IMC can reach speeds of 2400MHz or higher while others can't work more than the specified/rated frequency. There is no guarantee beyond the rated frequency. (You are technically overclocking the RAM if you run it beyond the specifications.)

In the case of the 4960X the maximum rated speed is 1866MHz. So intel is guaranteeing that it will function up to 1866MHz provided you have RAM that is tested and validated. Any frequency beyond 1866MHz is not guaranteed, but it is very doable provided you have a CPU with a good "IMC".

Like with any overclocking it's just chance as to what kind of CPU you will end up with. Some CPUs are strong overclockers while others can't go beyond what's specified.

I hope this helps, good luck!

Many thanks for explaining iatacs. I did some more digging and found that 2400 mhz does not provide that much effective advantage compared to 1866, so I'll just stick with that smile.gif
