PC Processors

[Semthexx]

Alright, where to start -  i guess with the specs:

Win10 Home build 10.019044 x64 based

MoBo Asus x570 F Gaming

CPU R9 5900x

GPU XFX 319 Speedster Merc (repasted)

PSU Corsair HX 1200

RAM 32 gigs Trident Z Neo from G Skill

Problem description:

My pc crashes under gaming, once it crashes it may crash 2-3 times befor even windows boots up. then it crash,  after the initial crash, after opening the browser.

Any clues what might be wrong?

I underwolted GPU, disabled half of my CPU (in order to prevent power draw) - nothing.

In the Event Logger i get quite a bit warnings, for example

a lot of Kernel PnP event 225

WHEA Logger  19

and a lot of Distributed  COM 10016

And yeah, all drivers are up to date, and windows and chipset

type of cooling on your CPU?

CPU/GPU temps?

is your motherboard's BIOS up to date?

What speed is your RAM actually running at? What is your FCLK set to?

IF DOCP/XMP is enabled .. do you have issues with it disabled? I've ran into issues with RAM that needed a small voltage bump to run at it's rated speed stable.. from 1.35v to 1.36v, 1.37v etc. 

DCOM errors are not a big deal ..

My cpu temps dont go above 75 C (360 AIO) and my GPU under stress goes up to 85 C and 104C junction temp.

My ram is on 3000MHz, i never screwed with FCLK thing. i just put it to it rated speed.

Edit: my FCLK is on auto, and i increased the voltage on my ram on 1.36. Lets see what is going to happen. Hope i dont blow this **bleep** up

[ThreeDee]

3000 speed RAM is on the slower end of the spectrum.. which puts a matching  FCLK at 1500 .. usually "Auto" works correctly at 3200 or slower speeds

I was running my 2 x 16GB 3200 CAS16 1.35v sticks at 3800 CAS18 1.390v without issue with 1900 FCLK before going with the 4x16GB Oloy 3600 sticks

There are many that OC their RAM above rated specs and run 1.50v 24/7 .. I don't personally like to run North of 1.40v .. so 1.3xxV isn't going to burn anything down,lol 

[Semthexx]

I dont know why, how or what that does but it actually solved my problem... increasing voltage on RAM to 1.36

[ThreeDee]

some RAM kits just can't run stable paired with some motherboards/CPU's ..etc .. at their rated XMP/DOCP voltage and just require a little bump .. could be that the motherboard isn't supplying the full 1.35v to the RAM even though it says so in the BIOS .. but something like CPU-Z or AIDA64 in Windows will say 1.34v or something lower

I think they call that vdroop?

[Semthexx]

it crashed again... i ncreased the voltage to 1.37.  But what does FCLK do. Ive read about it and the fabric has its own speeds. What does this fabric OC do
