DDR4 Memory clock speeds tinker

Hi everyone,

Long story short, I am trying to troubleshoot what is wrong with my PC and I think RAM clocks would make sense to be overlooked as of what is best to have it set as.
When I say troubleshooting, it restarts randomly without any warning, sometimes (rarely) it gives blue screen and in logs nothing is pointing that would give any information taht would help.

In the process I have replaced:
GPU, PSU, tested RAM with Windows memory diagnostic (test came out with no errors) and PC is still restarting randomly. Usually it happens when giving it just a bigger load. This makes me thinking if it is Motherboard or CPU (I know it is VERY rare that they break). But before I would be looking to swap CPU I thought I can have a look to RAM timings and see if it will be any help.

So, currently I am having:

  • AMD 5800x
  • MSI MAG X570 TOMAHAWK WIFI AMD Motherboard
  • 2x of Patriot Viper Steel 16GB (2x8GB) 4400MHz DDR4 Memory Kit
    Voltage: 1.45V
    Latency Timing: CL19
    Speed: 4400MHz (PC4-35200)
    2 x 8GB DIMM Dual Channel Kit
    Intel XMP Profile Support
    non-ECC Unbuffered Memory

Initially reason why I bought this RAM it seemed that it is a great win of the item, great CAS Latency (CL19-19-19-39) and it can be downclocked with getting more room in latency that could be worked out in lower CL. Taht is what I have initially thought but now I started to think that I was wrong.

Just to mention, PC worked fine when it was first assembled and load tested, I was even able to get stable clocks on 3600MHZ CL14 and CPU set accordingly to match (half clock).

Wonder if you could help me to get to safe and stable clocks for RAM and CPU to be alligned?

Any other advice is appreciated in advance!

you won’t get much benifit out of anything past 3800mhz ram, you might get it to 4Ghz but after that you’ll have to de-sync your fabric clock

you might be able to lower the latencies to take the place of the unfilled freqency headroom

Yes, Taht was the idea of purchasing them. However, looking to “best practices” to be stable, of what exact clock timings to use to have stable system.
