The software shows it as CL14 instead of 3600C16 because of the imported XMP file from TP. You should adjust the voltage setting to 1.35V manually.

No, this wasn't calculated from scratch. It matches the input provided by Thaiphoon.

I'll test these settings on a TCL16, but the system still won't start.

It seems there was a concern about Ryzen favoring even timing values, such as 14 instead of 15. For this to occur, the original timing settings needed to be odd numbers. Clearing the CMOS and setting the DRAM voltage to 1.35V might resolve the issue.

I attempted to adjust it to 1.35v but it won't start.

Have you checked if the XMP preset actually functions first? For example, turn on XMP and verify the DRAM voltage is set to 1.35V. The XMP specification details are 16-16-16-36-(2T), 1.35V. EDIT: You pressed the 'Calculate SAFE' option. Those timing values aren't the exact XMP import settings. I can confirm this based on...

Only secure calculations function properly when you bring in XMP data from that burner.

Open DRAM Calculator and press the 'Import XMP' option. Make sure you're using your laptop, then retry once I'm back from work on my desktop.

Could you check if an older version works? I'll attempt 1.35v, but it doesn't start up.

Version 1.7.3 is the most recent release. The laptop didn’t require it. XMP profiles typically need 1.35V, which is standard for DDR4-3000+. JEDEC guidelines specify 1.2V for DDR4-2133, though some kits support 1.2V at lower speeds like DDR4-2400 or DDR4-2666. Could you share your motherboard details, BIOS version, CPU type and model?
