CPU Strange errors in stress tests

Greetings!

 

Here is my initial build

 

Core i9 7900X at stock + DeepCool Captain 360EX AIO Cooling

ASUS Rampage VI Extreme - BIOS Default settings - no overclock

16GB of Kingston HyperX DDR4 memory (2x8GB) at 2400MHz HX424C15FB2/8

GeForce GTX 1060 6GB

1x Intel Optane 900P 480GB

1x Samsung 850 Pro 256GB

2x WD Black 1Tb

2x WD 640BG

PSU Corsair HX1200i

 

No so long ago I've decided to add more RAM and bought Corsair RAM Kit 8x4GB (VENGEANCE LPX) CMK32GX4M$B3866C18R. After installing new memory and activating XMP 3866 profile I run benchmarks such as MemTestPro, LinX and OCCT. OCCT as soon as 90% of ram was loaded printed an error Stopped Error Detected. Then MemTestPro also found memory errors. I turn down memory voltages from 1.35 to 1.2 and frequency to 3200. OCCT continue to show an error as soon as memory allocation completed but there is no more errors in MemTestPro. First of all I thought that the RAM kit was faulty and bought another four memory modules from Samsung (M378A1K43BB2-CRC DDR4 2400MHz) and situation was the same. Same unknown error in OCCT and no errors in MemTestPro. So I've decited to try all this memory in another PC (Ryzen 7 1700X, CROSSHAIR VI HERO) and they all worked perfectly fine, passing OCCT and all tests. Also I've tried to test system with only two memory modules inserted and they worked perfectly fine too. Seems like on the Rampage VI Extreme four modules (QuadChannel mode) configuration causing errors in OCCT regardless on any memory I use. 

 

Is there any way to get more information about an error in OCCT or other way to find out the root cause of this issue?

 

P.S

Temps while in OCCT 

74-82C CPU, 68C VRM

Did you apply XMP or just raise the frequency to 3866 without XMP?

As for Corsair kit I‘ve enabled xmp that automaticaly set 3866 and all the timings and voltages for me and when I change frequency to 3200 and voltage to 1.2V I just changed appropriate settings without dissabling XMP. As for Samsung RAM it was at defaults 2400 by SPD with no XMP enabled

Was the Ryzen system running this kit at 3866?

 

I'm suspecting not enough Vccio and Vccsa. 3866MHz is kinda high and if your CPU isnt good enough, it wont do it properly. As for why 3200MHz get errors, I suppose 1.2V isnt enough (many DDR4 3200MHz run 1.35V, with most likely worse timings than yours)

Ryzen stable at 3200MHz (D.O.C.P 3200) and passing all the tests with no errors as for Corsair Kit. I haven't tried Samsung ones on Ryzen yet.

Was about to say have you considered the motherboard as maybe being faulty. Maybe the traces on the motherboard could be faulty

Seems so. I've found this on socket after dissasembling. May be this is the cause of the problem? I've got another X299 motherboard from MSI (MSI X299 SLI PLUS) I'll to move my  build to MSI MB an rerun tests.

It could be that but as far as bent pins go that doesnt look bad. maybe try reseating it all then have another go. Im running a 7820x and its bee rock solid for my needs
