[SOLVED] 3600MHz RAM won't run at 3600MHz (Intel) ?

[Creadoris]

I recently purchased a 32Gb G.SKILL RIPJAWS DDR4 3600MHz RAM kit which I am using to upgrade from 16Gb of Themaltake DDR4 2666MHz.

Swapping the sticks out went fine. However, windows indicated the RAM was still only running at 2666MHz which I believe is the default for my ASUS board.

A quick bit of googling revealed I would need to go into the BIOS and pick an XMP profile in order to tell my PC to run the RAM at the specified 3600MHz.
There there were 2 x XMP profiles to choose from, but unfortunately both resulted failures to load into Windows. Either because of boot loops or blue screens.

I have attempted to further search for a solution to this issue, but it would seem the majority of RAM overclocking discussions are predominately geared toward Ryzen chipsets.
I am not overly keen to go manual and experiment with voltage or clocks speeds; perhaps someone with some Intel chipset overclocking experience who could offer some advise.

My Specs:

CPU: i7-9700KF
MOBO: ASUS Prime Z390M-Plus (BIOS recently updated)
RAM: 32Gb G.SKILL RIPJAWS DDR4 3600MHz (2x16 RAM Kit)
GPU: RTX 2070 Super
OS: Windows 10 Pro

Hi Creadoris 👍and Welcome to the Forum


The i7-9700KF officially supports up to 2666Mhz so you will have to try and manually program your Bios SPD for them to work. There will be no guarantee you will reach 3600Mhz frequency (even tho your MB supports up to 4266Mhz 0C RAM)as that will rely on the strength of the IMC (Integrated Memory Contoller) on your chip.

There are a few things to try: Do this with just one DIMM in the slot meant for single channel mode.

1. Loosen the Primary timings by 1
2. Increase DRam Voltage in .01 volts steps (not more than 1.4v)
3. Change the Command Rate from 1 to 2.
4. Try working at 3200Mhz and work up.

Should these steps fail then return what you have for a single kit at a frequency the CPU and Mb support and chosen from the MB QVL and that way you know they are tested and known to work.

Thank you for the prompt response.

I will try what you have recommend.
