Memory speed limited by CPU?

[CovidCid]

I recently purchased a set of crucial 16 gb 3600 mhz ram. I have an i7-9700f. I can't get it to boot normally with xmp setting the frequency to 3600 mhz. I have to use 2666. Is there a way for me to get a the ram to 3600 mhz?

Also I'm going to purchase an i9-9900kf soon

Then manually set it. Follow the speed and timing on the box, and set a higher voltage than what the box says.

I manually set 3600 mhz and CAS latency 16, however it would only boot into safe mode until I turned it to 2666. The box says 1.35 V, so how high should I turn the voltage?

You can go all the way up to 1.45-1.5V, but my tolerance for daily driving is around 1.4-1.42V.

My bios won't let me go past 1.4 V. I tried every single timing from 3600-3200-3000-2933-2800 and only 2666 mhz will let the system boot. Do you think it's a cpu issue?

What motherboard do you have..

 

CPU/RAM/BOARD are ALL co sodered a factor for attaining the Memory Speeds (XMP) You paid for...

I have an asus tuf b-365m

There's your problem.

 

B365 chipset based motherboards does not support DRAM overclocking.

You have a K-series CPU, but your motherboard is limiting you.

You need a Z370 or Z390 motherboard.

 

Intel changed their XMP / DRAM overclocking policy with 10th / 11th Gen CPUs with non-Z chipset based motherboards.

For any of the older generations, 9th Gen and older, you MUST use a Z chipset-based motherboard.
