New PC Build random freezing/black screen

[pr1970]

Hey All

I`ve just built a new pc and after installing windows 10 for the first time i`m getting random freezes/blank screen. It could run for 15mins or 6hours before i need do a hard reboot. There maybe nothing running apart from firefox, and then the mouse freezes up, then blank screen and fans go into overdrive for a second and nothing. Have to power off and on again.

System is
Asrock x570 Creator motherboard
AMD Ryzen 9 3950X
NVIDIA GeForce RTX 2070 SUPER (Taken from my old pc so i know its fine)
64gb ram - Corsair VENGEANCE® LPX 64GB (2 x 32GB) DDR4 DRAM 3600MHz C18
Be Quiet Dark Rock Pro 4 cpu cooler
1000W EVGA GQ Series PSU

I`ve run some stress tests, cpu maxes out about 82c and GPU 66c .
Here are some system info. I havent touched the bios, next thing to maybe update that. I did notice the memory speed was down at around 3200mhz when set to automatic, not 3600mhz. Everything is on automatic, wanted to check its stable first before changing values, although i have no clue about memory oc.
Thanks all.
Heres some info images from asRock tuning and hwinfo64

Sorry to say, but it might be the RAM. Corsair LPX and Ryzen CPUs are not a good combination and you wouldn't be the first one having issues.
Also, you're the first one I've seen here with two 32GB modules, so it's hard to give any real advice, beyond running some memory stress tests and see how that goes.
As for the clock speed, it's possible that the memory controller is the Ryzen CPU doesn't like that much RAM at clocks that high, but you're in somewhat unknown territory.

Yeah it sounds like the ram could be the issue, painful issue for you as you have so much of it but sounds that way.

ok thanks, I did check that the ram was on the asrock motherboard recommend list before I purchased.
I'll run some stress tests, I've also updated the bios.
any recommendations for memory tests ? Perhaps a DOS version so it avoids windows .

If you're getting random hard resets it's most likely ram timings issue.
Memtest64 should be able to stress it enough to cause a hard reset if timings are unstable. In my case it would crash within 20 minutes.

Dram Calc might help improve things.

This has a built in test as a first step. It can also help with finding memory timings that should work, but you need to install Thaiphoon burner as well.

The official memory support breakdown from ASRock for your board below. I wouldn't read too much into it though, but it tells you that anything over 3200MHz is a bonus. That said, most people can run at 3600MHz with single ranked modules, but you most likely have dual ranked modules and very high capacity modules at that. Even so, up to 128GB is meant to work so...

thats great, thanks all.
I`ve updated the motherboard bios anyway. have got the dram calculator and running heavyload for about an hour. so far so good.

I would imagine the BIOS update has solved the issue - Corsair LPX is super common RAM so AMD likely targeted it for stability improvements in one of the AGESA updates.

If you still get lockups, disable XMP and run it at JEDEC 2133 defaults for a couple of days to see if that helps improve stability or not....

What is this HeavyLoad? I suggest MemTest64 OR HCI MemTest (one instance by thread) OR Linpack Xtreme with maximum memory.

Sure, it's common, but a lot of people are having problems with the LPX modules, for whatever reason. I couldn't get the ones I had to work properly at 3200MHz, across two different systems. I'm far from the only one as well and AMD had that exact revision on their QVL...

HeavyLoad is a simple program for loading/stressing the CPU, but clearly not a memory stress test program as such, even though it has a memory test as well.

Thanks, so far no locks ups. Had run Memtest64 for about 2 hours. Did get a weird effect that it seemed to stop refreshing itself when my windows went back to login screen. But i saw it was no errors for an hour and a half. I`ll maybe give linpack xtreme a go tonight from efi boot and leave it running.
