Ryzen 3950X Build Help

with my CH8W mobo i noticed even with the power off the RGB LEDs and other LEDS are running, does that seem normal for modern boards?

Yes, specifically Asus boards do that my Maximus XI code does the same thing you can turn it off in the bios though.

If you unplug your HDMI/DP cable they should switch off. At least they do that on my system

Phew, managed to order one !!!!

Were you able to grab one? They sold out before I could even click on the page lol.

Oh I have 0 interest my 3900X/9900k combo is already pretty overkill.... I was more curious about how fast they would sell out.

Congrats on being able to pick one up.

Seems like NewEgg had very little but Micro Center has a whole bunch

Micro Center now sold out Online as "AVAILABLE FOR IN-STORE PICKUP ONLY." now

How do i get my ram to work correctly? it's not doing 3600 MHz or even close ....

Looks correct to me.... you double the 1800 to get the 3600MT/s. Seems like your Fclk is running properly as well at 1800mhz

Looking good man.... I'm excited to see it all finished and cable managed.... also use R20.... R15 is not a great fit for 8+ core CPU.

need a new HDD ... mine just kicked the bucket

So I might have a number of bad components already... not sure which it is... memory, cpu, or mobo? seems to always land on CPU: "24" so far ...

Another pass:

Wonder if Memtest, as newly released as it is, would be good for testing that chip?
This version was released Nov. 22nd 2019.

Have you tired any other testing? AIDA64 maybe? LinPack?

Another pass:

How does it behave when you relaxing your timings or frequency - will it pass at DDR4-3200 or looser timings?
( Remember Zen2 spec is DDR4-3200 anything over that is OC )

AMD Ryzen Memory Tweaking & Overclocking Guide

Memory overclocking has a significant impact on performance of AMD Ryzen-powered machines, but the alleged complexity of memory tweaking on this platform, largely fueled by misinformation and lack of documentation, has kept some enthusiasts away from it. We want to change this.

i'm running prime95 "Large" test stressing memory and memory controller and basically i'll get some issues with chrome and black screens temporarily

i already swapped the ram chips that was the 2nd test you saw

I have a feeling you just need a little nudge somewhere to get stability since you only have a few errors.

Can you provide a screenshots of Ryzen Master showing it's detected memory settings and SPD chip details from Thaiphoon Burner (http://www.softnology.biz/)?

i bumped SoC to 1.1V and DRAM to 1.360V

How many sticks do you have installed?

 

[Deleted member 185158]

Wonder if tRFC isn't loose enough at 630 clocks. You could try looser say 700 clocks.

Looks like your tRC is really loose in comparison to your XMP profile. Should be 58 not 85. Take that off auto, and set this manually.

It was 2, I’m trying with 1 now as we speak

 

[Deleted member 185158]

Testing on single channel to run 2 sticks may help if you can test both sticks properly, you gotta set up your memory timings the best you can manually. Don't forget the tRC timing should be correct for proper XMP functionality.

Also, the memory controller may not like the Cas 16-19-19 either. IMC can be picky that way.

Make sure they are installed in slots A2 and B2.

tRC does seem high as ShrimpBrime pointed out. One simple thing you can try real quick is to change your timings to match the Thaiphoon Burner output for 1802Mhz as from your screen shot and set everything else to AUTO but keep your SOC and DRAM voltage. Also try PROC ODT to 60 ohms. (set all in BIOS/UEFI - NOT via Ryzen Master)

Can you use HWiNFO64 to output your DRAM data. I want to see if it provides the XMP timings in nanoseconds for your ram. Since the tRC was off maybe something else if off too and we can calc a reasonable value in particular for your tRFC.
