Yes, the CPU and memory share the BCLK, I said that in my last post. With the CPU Ratio (multiplier) set to Auto, you can't see the actual values on that screen.
Now your CPU speed is making more sense, but as we can see in your screenshot it was not 2600MHz, it was 3346MHz with your memory at 3600MHz. The Auto setting of the CPU Ratio adjusted automatically to compensate for the BCLK at 128.7 MHz, which is an unusual value.
The Auto setting of the CPU Ratio (multiplier) must have not changed for some reason, when you set the memory to 2400, which is when we see the CPU speed at 2600 in your screenshot.
Of course you can set the memory speed manually, as J Z is demonstrating in the video. I just hope your memory will cooperate, since G.SKILL does not list it as compatible with X99 systems. Check the QVL tab on this page:

Coz I did not venture into the CPU configuration which also had a setting for BLCK Frequency.  This is my memory specs: http://www.gskill.com/en/product/f4-3600c17q-32gtz My motherboard spesifications http://www.asrock.com/mb/Intel/Fatal1ty%20X99X%20Killer/?cat=Specifications Supports Quad Channel DDR4 3000+(OC) So I was hooping at least to get 3000MHz and to set lower timings. I know of some who has gotten G.skill memory on X99 with 3400MHz (but that was an Asus MB). |
