You won't see much benefit going from 3200 to 3600. You now have the RAM working
so you can feel free to experiment with timings and frequency. Google for a good
guide, there are plenty out there. You can start by simply selecting XMP and then
3600 from the dropdown menu. If that doesn't work you can clear CMOS and try the
next setting down until you get your maximum bootable frequency. If you really want
to get the most out of your RAM then you can follow a guide. I honestly don't think
it's worth it from a practical standpoint but to each their own.

I personally wouldn't follow chat GPT advice for anything, it's too easily influenced
by bad data. ]]> Wed, 16 Jul 2025 00:40:12 +0000 https://forum.asrock.com/forum_posts.asp?TID=17463&PID=198426&title=cant-run-ram-over-2667mhz-on-z370-pro4#198426 https://forum.asrock.com/forum_posts.asp?TID=17463&PID=198423&title=cant-run-ram-over-2667mhz-on-z370-pro4#198423 Author: colin538a

I managed to start in 2 and 4 slots I don't know why the first time I didn't wait maybe I was afraid of reboots and black screens)
I chose xmp profile in which voltages 1.45v and set frequency 3200 and started from the first time all good start from the first time before this voltages were auto 1.352 there were problems if higher than 2666.

I think it can be better here is the merit of Samsung and not mine, but my hands are crooked and the shoes are weak one cooler on the inlet so I will stop.

gpt chat advised 13-13-13 timings and called cl14 slow.

and reduce TRFC to 320 but I'm not an expert who knows if this is good advice?)))

overclocked system agent, and FCLK was about 2700mhz but the system does not start from the first time and makes 1 reboot so was from Kingston Praetor at 3000mhz

Dear Noob3000,

Thanks for posting!

Let's see, when two memory modules are installed, it is recommended to install the A2 and B2 slots.

If the problem remains, kindly try the following to troubleshoot.
1. Install only one RAM to the B2 slot and XMP to 3200MHz.
2. Try the same with the 2nd RAM on the B2 slot.

If both of the RAM work at 3200MHz on the B2 slot and also on the A2 slot, if possible, please try with a different CPU to see if it will work.

With thanks,
ASRock TSD]]> Mon, 11 Jan 2021 15:50:17 +0000 https://forum.asrock.com/forum_posts.asp?TID=17463&PID=83004&title=cant-run-ram-over-2667mhz-on-z370-pro4#83004
