Computer restarts while playing games

[Thming]

So i just built a new pc and i have a problem where my computer restarts in the middle of a game. All the games run smoothly. but at random times it will restart. the RGB stays lit up so it is not completely turning off. All parts are new except for my power supply, but it was in my previous computer and didn't have any problems with the old computer. any ideas? In my BIOS i did change what the memory was set to because it was not set at 3600. should i change it back to what it was at default?

Spec::

AMD Ryzen 7 3700x

MSI Geforce RTX 3060

Corsair PSU 850W

ASRock Phantom Gaming 4 B550 motherboard

Samsung SSD980 1TB

Crucial Ballistix gaming memory 16GB DDR4-3600

Does it bluescreen or show any errors, or does it just plop right back to POSTing immediately?

Couple clarifying questions: 

 

1. Is this a black screen or restart? (IE: black screen but otherwise computer running, might be able to still hear game sounds)

2. Was the computer running well before you modified the memory timings? 

  2a. What specific memory model and JDEC & XMP timings? 

3. How old and what model of PSU? 

4. Are you overclocking anything at all? If so, what specs (Clock/volts)

Right back to POSTing

If this happened after you set the ram to XMP 3600, my bet is that the memory is wanting a bit more voltage. It seems these micron chips sometimes need more voltage than what they are rated to operate trouble free. Bump the ram voltage up to 1.375v and test again.

1. it will restart.

2. loading in games took a very long time. had about a 1 second delay for inputs.

   2a. BL2K8G36C16U4B memory model. i am not sure what the other 2 you are referring to are

3. CP-9020196-NA purchased in 2019

4. DRAM Frequency was increased to 3600 ( it was running at a lower frequency but I forget what it was.) Dram volts: 1.200V

sounds like you push the ram frequency up without XMP (DOCP). This will only push speed and not provide the required voltage increase needed. Enable the XMP profile for the ram as your ram requires different timings and voltage to run @ 3600. (voltage should be 1.35 for 3600 rated)

Same problem happened when trying to play insurgency Sandstorm

while play GPU utilization: 93%    CPU utilization: 13%

At this point it would be a timing AND voltage issue. Make sure to us the XMP profile in the bios.

Same problem

ok, looks like your board is a bit finiky with the choice of ram. is there an OC mode available in your bios? 3600 is an OC for your board. If there is a 3600 OC mode, flip that on. otherwise, you might need to run it at a lower clock or find some different compatible ram for your board.

I just set everything to default and the problem seems to have gone away without having any problems to when i first started the computer.

Right on. 

This is not to say you cant run higher Ram speed, but 3600 looks to be pushing it for your setup. 3200 is a great speed to shoot for that gives good performance for your CPU. If your board has preset ram speed values, you might want try that, or have your hand in brushing up on RAM OC tactics and have a go at a manual set OC. There are MANY people here that would be willing to lend some assistance with that. 

 

I'm glad you at least can get a stable system in the mean time. Best of luck to ya!
