Hello, my XMP settings make my computer act up. I want to fix it by changing voltage, speed, and timing manually. But a friend told me that if I want to overclock both RAM and CPU at the same time, I need to start with just the CPU first (making sure RAM stays at its normal, non-overclocked speed), wait for everything to get stable, and then finally go ahead and overclock the RAM. Is this right? What should I do if I only want to lower the CPU's idle temperature instead of overclocking it? Should I undervolt the CPU before trying to overclock the RAM? Here are my computer details: CPU is an AMD Ryzen 5 3600X, with 2x8GB of Corsair Vengeance LPX running at 3200MHz. My motherboard is a Gigabyte B450 Aorus Elite (version 1.0, BIOS F52). I have an EVGA GeForce RTX 2060 GPU and two hard drives: a Samsung EVO 970 Plus with 250GB storage and a Western Digital Blue 2TB drive spinning at 5400 RPM. My power supply is a Corsair TX650M

Yes, you should do that so you don't accidentally hurt your RAM while testing CPU stability on the Ryzen platform. Limit the variables when doing this. Also, the DRAM Calculator for Ryzen v1.7.3 helps with overclocking your memory on AMD's platform.

I found that setting the DRAM voltage manually makes my XMP profile stay stable. Maybe just my motherboard causes trouble, but if you only want XMP settings to work, try it out! If you want to run your RAM at higher speeds than the XMP clock speed, use the DRAM Calculator as a great tool to figure out what times and voltages will make it work.

@drea.drechsler and @tennis2 Even though I gave you all the right info, DRAM Calculator didn't give good RAM settings for both FAST and SAFE modes. In fact, in SAFE mode it gave times lower than my RAM needs when running overclocked. But there is hope! I found a forum post where another user had this same problem too, and they got help to make their RAM work with XMP. It didn't work because the tRC timing value used by the XMP profile was wrong. Changing it to the correct number fixed the issue and Memtest86 ran perfectly.
