Terrible RAM Speed Ryzen 3700X X570-F Gaming

Hello,

 

I hope one of you guys can help me with my problem, I have for sticks of Patriot Viper RGB in my System, advertised as 3600Mhz CL17, but the RAM Speed is just terrible.

I set DOCP in BIOS and choosed the XMP Profile but that has no effect at all, the meory is still at 2133MHz CL15, when I manually set the Frequency to 3600Mhz the system works, but if I leave timings untouched it Auto sets them to CL26-30-30-44 or something like that wich is very bad. So if I manually set all the timings to values that are advertised in the XMP profile DRAM Voltage to 1,42V and Chipset to 1800MHz, I can barely boot the system, it's very unstable and crashes after about 3mins of idle. The memory doesn't even run CL18 or CL19 stable, it even sometimes crashes in games on CL26.

 

So my question is, what am I doing wrong, and why is XMP on Auto Settings not working at all.

BIOS is newest Version, Drivers all up to date. The Memory is listed in QVL but only for 2 DIMMs but can that have that much of an impact, I've never had such problems with my old DDR3 system.

 

System:

ASUS X570-F Gaming

Ryzen 3700X

ROG Strix 1080Ti

650W EVGA Platinum

4 Sticks of PATRIOT Viper RGB

no one ever said that 1800MHz FCLK is stable in all CPUs

First find what is stable to your Fclock and then mess with ram.

It's 4x8 Sticks (32Gigs) If I have Infinity fabric on 1800Mhz and RAM on 2133, prime95 keeps running without issues so I assume it's a memory problem.

mix of two kits right? Viper RGB only come in 2x8GB config

 

higher capacity and more sticks hurts overclocking potential. They arent rated for 4 stick operation either, so don't blame the sticks for not working.

Lower memory speed = less data waiting to pass through Infinity fabric = More stability.

That's just awfull how big of an issue can that be? I just should have gone with the 4x8Gig G.Skill Kit :(

What do you recommend than 3600MHz bad latency or lower Frequncy and better latency.

Also how much Voltage will a DDR4 usally take 1,5V still safe?

 

EDIT: What I'm still not getting, why does the XMP Profile have absolutely no effect at all? It stays on 2133MHZ CL15 when I choose XMP in BIOS

 

EDIT: Well, after a whole night of tweaking trying and crashing, I got it all stable at 3600MHz 18-19-19-19-42 that's a latency about 72ns, That's about 5ns about the sweet spot of the ryzen I am fine with that, thanks for your help anyways.
