Trident Z Neo 32GB (2 x 16GB) F4-3600C16D-32GTZN Won't Run Properly with R7 5800x

I upgraded from a R5 3600 to a R7 5800x. I changed no other parts. XMP profile on motherboard worked just fine using R5 3600. Now computer won't even boot if set to 3600 MHz clock or using XMP profile. The maximum the system will boot is a manual setting of 3533 MHz.

There was one single instance where I could get it to boot at 3600 MHz, but timings were like 26-26-26-??. After this, it never booted again at 3600 MHz.

Any ideas on a fix?

Motherboard - ASRock x570M Pro4 running latest version of BIOS 3.40

Are you able to get one module running at DDR4-3600? Do you have memory in slots two and four away from the CPU?

So DDR4-3533 with XMP CL16 works fine? Try adjusting DRAM Voltage and/or CPU SoC Voltage to see if it can improve results.

Thanks for the prompt reply. I do indeed have both sticks inserted into slots two and four. I will try removing one to see if it runs at DDR4-3600. I think it will be a big pain in the butt with the CPU cooler sitting right on top of the DIMM slots lol. I'll report back in once done.

Forgot to acknowledge your other question - yes, it appears to run at DDR4-3533 CL16, but not via XMP. I got this to work via manual tweaks in the BIOS:

I'm running my system with 1 stick of memory in slot 2. I made sure to run the XMP profile in BIOS before booting. It's not running at DDR4-3600, and the timings are odd. See below screenshot

*UPDATE*
I reinstalled the second stick of memory and set the BIOS to run the XMP profile (XMP sets DRAM voltage to 1.35v). At first, I tried setting DRAM voltage to 1.36v - this failed. I then tried 1.34v - this also failed. I set it back to 1.35v, but then changed SOC voltage to 1.1v. This worked! System is back to running dual channel @ DDR4-3600

Thank you, GSKILL TECH!

I ended up getting a 5950x lol. Love it. Insane CPU.

But I sold the 5800x to a buddy, and he's running Ripjaws 16GB (2 x 8GB) DDR4 3200 (PC4 25600) Model F4-3200C16D-16GVGB. They are in slots 2 & 4 on his Gigabyte Aorus x570 Elite WiFi motherboard w/ most recent F33g BIOS.

He's experiencing almost the same problem as I was. Memory will only run at 2133 MHz, and XMP profile will not work. We've tried numerous different combinations of DRAM voltage (1.30V - 1.38V) and SoC voltage (1.00V - 1.1V). No other adjustments on the system are being made; it just restarts, displays the Aorus logo with BIOS options, shuts off, and repeats.
