Stable Overclocking Settings [kinda solved]

[Roman_Gruber]

Hello.

I hope it fits here.

I have those components.
Ryzen 3700x
Crucial Ballistix red DIMM Kit 32GB, DDR4-3600, CL16-18-18-38 (BL2K16G36C16U4R)
B550 MSI Gaming EDGE WIFI

I only use 3600MHZ with a bit lower timings and a bit more voltage on the RAM.

When I understood correctly anything more than 2666MHZ for the RAM for a 3700x is already considered overclocking.

Can I assume the overclocking of the memory modules is working when the box can generate code? Portage does not fail?

Roman_Gruber,

No. How do you test that the code is correct?

The code generation may be OK but more complex operations may still produce the wrong answers.
You could have the self induced equivalent of the FDIV bug and not know it.

While running memory at 3600 is overclocking, the manf has declared that it is safe to run at that speed, with the voltage they recommend and the CL settings.

I have a 3700x w/3600 memory and it runs fine (I use the stock XMP settings in the bios) been running stable for quite a while now.

You could run memtest for a few hours. That has always seemed to correlate strongly with a stably operating system for me.

There is a bit of bureaucracy involved in DDR4 "overclocking": Part of the standard is the voltage, but many manufacturers design memory to run over the standard voltage to achieve faster speeds, and as long as you stick with the published* settings for your hardware you'll be fine.

*That obviously includes channel/freq limits set by your CPU docs too.

I hope someone does not mind when I bump my old post.

I managed to find a process on how to determine "useable" "stable" "overclock" settings for a Ryzen 5800x with a Gaming EDGE WIFI B550 Mainboard from MSI with Crucial RAM.

My particular platform does not generate any WHEA errors with infinity fabric clock 1866MHZ. I check in windows with a hardware monitor software. Any IF Clock at or over 1900MHZ generate no POST or a lot of WHEA. Usually unstable settings generate quite quick sound glitches when playing sounds, or WHEA or system freezes in combination with my USB keyboard.

I could find some settings which are WHEA error free for quite some time while "windows 10" gaming.
These settings were set in UEFI bios.
these settings could generate in my personal point of view "error" free gentoo compiles.

In my point of view with the same mainboard and 3 different cpus I could never reach the internet claimed high infinity fabric clocks. I doubt it is cpu related as two fresh out of the box 5800x and one used 3700x could not bring any results.
I also used beta Bios and different official bios for the mainboard.
I could tweak a lot the primary and subtimings of the DRAM.

It is very important when using windows for determing stable settings to stress a lot the DRAM to find issues.

In my point of view a B550 mainboard is not worth in regards of overclocking. The hardware nearly runs at its limits except the DRAM.

I wanted to share my experience. Maybe someone find the information shared here useful.
