Possible to OC the 64GB DDR4 G.Skill 2133 to 2666 ?

[hunterx2210]

My spec:
i7 5930k 3.50GHz already OC to 4.5Ghz
64GB G.SKILL Ripjaws 4 Series DDR4 2133, already OC to 2400
Motherboard: Asus X99-DELUXE/U3.1
PSU: EVGA 120-G2-1300-XR 80 PLUS GOLD 1300 W

My question is it possible to push my RAM more to 2666 ?
Is there will be any problem ? Like too fast that causing crash ?

Your going to be looking at instability issues going past the XMP profile and you would not see any major increase in performance for gaming, if that's what you want. It also depends on the strength of the IMC and not all Intel chips perform the same. The MB also has a MAX frequency support.

For the sake of science, try it and see.

Yep, except...

I do NOT recommend pushing it further.

Not only would the benefit be minor or nothing depending on the application but stressing 64GB of memory is worse than stressing less memory so you can cause problems. Problems that may not be obvious at first, but over time cause data corruption of various files until suddenly things start not working right and you do not know why.

*to be clear, you CAN damage the CPU by overclocking the memory (especially changing the voltage)

It is very possible and capable to overclock G.Skill DDR4-2133 modules to 2666. You will need to raise timings or Voltage, depending on which you prefer to boost performance. Once the proper settings are input, the system should be perfectly stable.

The motherboard and CPU is very capable as well, as long as you scale up accordingly, you should have no problems. Harm can only be done if you decide to input random high Voltages in hopes the system will just magically become stable.

For a starting point, you can try:

DDR4-2666 16-16-16-36 1.25V-1.30V

Then test and see whether you would like to keep Voltage higher to maintain lower timings, or keep timings higher to maintain a lower Voltage. Using a memory benchmark test, you can determine which setting is faster/better.
