Trouble overclocking ddr4 ram

[Hallowed_Thrall]

So I've decided to overclock my ram and everything is completely stable, it's just when I restart my computer it fails to boot once then succeeds after, this doesn't happen if I just shut the computer down then start it. Also, this only happens when I OC it over 2400Mhz. Running at 2933Mhz 1.35V.
Hope someone could help with this I can't find anyone else experiencing this.

put ram back to default settings then use cpu-z spr to see the fastest jedec settings you could use compare them to memory tab you could aslo activate the axmp in uefi bios to set them as fastest speed they could go .

DDR4-2666 Memory may run at slower speeds but higher speeds is not something that is a sure thing.

Running multiple kits have no guarantee to be compatible together and may cause the memory to be unable to operate at rated specifications and be unable to boot. That may explain why your 2666MHz memory won't run at rated speeds.

could you give use the full name and model of the ram .

It's in the pcpartpicker that i linked but here: 2x G.SKILL Ripjaws V Series 8GB 288-Pin DDR4 SDRAM DDR4 2666 (PC4 21300) Intel Z170 Platform / Intel X99 Platform Desktop Memory Model F4-2666C15S-8GVR

It'll boot just fine if I shut the computer down and start it, just not when I restart it. That's what doesn't make sense to me.

this ram is not even on the support list from is maker for you board and ryzen is picky on ram https://www.gskill.com/en/product/f4-2400c15d-8gvr

My opinion is i dont see any point in overclocking RAM, there is hardly much difference between DDR3 & DDR4. Its just more heat for a very small percentage in improvement of RAM performance
