Black screen on Prime 95 with default bios settings - new Ryzen Build

This is my first time posting on the forum, let me know if I am leaving out info I need please. I am having issues with a new PC I just built. Whenever I try to run Prime95, it crashes either immediately, or within 15 minutes. All of my lights and fans stay on. My monitor just says no input.
My bios settings are set to default. Below are my system specs:

Motherboard: Asus B350 Rog Strix
CPU: Ryzen 7 1700
Cooler: Stock (Wraith Spire)
GPU: Asus Rog Strix 1080 ti
Ram: Corsair Vengeance RGB 3000 15-17-17-35
PSU: Corsair CS750M
Case: Phatek Eclipse P400s
OS: Windows 10 10.0.15063
Boot Drive: Mydigitalssd BPX 480 GB M.2
Geforce Game Ready Driver: 385.69
Bios: 0902
Chipset Driver: 5.12.0.31

This is the 2nd PC I've built, first Ryzen build, and first attempt at overclocking.

I ran memtest for 8 hours after I got my parts because I was waiting on my ssd to install my os. After installing windows and having issues with constant crashes, everything seemed to stabilize after updating windows and all my drivers. I felt like I was ready to give overclocking a shot.

I started using Dual intelligent processors 5. It took my cpu up to 3.725 GHZ. Then, I decided it was time to overclock my Ram and test. I started reading about ai suite and Dual Intelligent Processors 5, and this scared me and convinced me to uninstall it. I decided I would figure out how to overclock with the bios. I restarted, and manually entered a 35x multiplier. I set my Ram to 2933 using DOCP. I restarted, with the intent to run Prime95 to test stability. After restarting and running Prime95 for 15 minutes, I decided to play Skyrim SE for a couple hours. I experienced no issues. After I was done, I turned on Prime95 and figured I'd let it run overnight. In the morning, my PC was off. I didn't know if it was due to inactivity or instability.

Later that night, I decided I was going to test my stability before doing anything else. I set my ram to default, set my multiplier to 35x, and figured I would make sure I was stable at lower settings. Based on my research, I should have no issues at 35x with stock voltages. After reboot, a friend started playing fortnite. I decided that I would postpone running prime and play fortnite because I thought I had settings that were so low they had to work. I played fortnite 3 hours with no problems. At the end of the night I decided to run Prime95. It immediately turned my screen black. Everything appeared to still run, but my monitor showed no input. I powered down by switching off my psu. I booted into bios and turned my settings to default. I booted again and started prime95. I had a failure almost immediately.

I've watched multiple videos and tried the following things:
High Performance Power Plan
Ryzen Balanced Power Plan
CPU voltage as high as 1.35 volts (it's an offset on my motherboard)
DRAM voltage as high as 1.40 volts and enter manual timings.
SOC voltage to 1.1 volts.
Turned off Windows 10 game mode.
Disabled Core Performance Boost
Disabled Global C-State control
Set Performance Bias to NONE
Took ProcODT to 48 Ohms, 53.3 Ohms, and 60 Ohms.
Swapped RAM with my other computer (Corsair Vengeance LPX 3200) and tried different DOCP profiles.

After all of this and multiple days of watching videos and troubleshooting, I don't know what to do. I'm hoping it's a video driver or something stupid I'm overlooking.

Sorry for the book. Thanks in advance for any help.

  1. OCing is tricky and take some time. Black screen means your setup is not stable enough, you will get there :) My suggestion is to google your MB/CPU/RAM pair and see what other people clock at and take an average to be your start point. It takes a lot of trials to get to stable setting. Moreover, update BIOS to most recent version, mostly they help with OC stability :) It took me a week to finally stabilize. For RAM, I suggest DOCP setting and 1.35 V should suffice. Just play with CPU voltage. Set some lower target first like 3.6GHz, try 1.2V first. Increase your CPU voltage slowly until it is stable. Save as profile 1. Continue to 3.7 next, etc. Be patient :)

  2. I appreciate your response to my post. I feel like I've got no starting point though. I'm unstable at stock settings. Where do I go from here? Do I increase voltage to try to make 3.0 GHz stable?

    Let's revert everything to auto then, including ram. Test if it is stable :) Then start with CPU only, gradually increase voltage and speed. Do ram last. I am using MSI OC genie to give me some starting point. I heard good story about Ryzen Master, you can use that as start point :) Don't give up, OCing is fun!

    I currently have everything set to default (30x multiplier, everything set to auto: CPU & RAM). If I start up Prime95 right now, my computer will crash within 10 minutes. That's my problem. I don't know if I need to overvolt to get to stock speeds? I'm going to test again right now.

  5. Is your BIOS up to date? Is OS a clean install?

    PC crashed again just now ran Prime95 for less than 1 minute. Bios is up to date (0902). I think OS is clean install. I installed it about a week ago using a new ssd and new windows 10 disk and key.

    New system with everything auto shouldn't behave like this. PSU is very suspicious? Can you borrow someone's PSU and try again?

    I'll swap with my other computer (it has an EVGA 600 BQ). I'll test and let you know.

  9. How about the temperatures? Have you checked them? Is the CPU cooler properly mounted?

  10. This time also monitor your CPU temperature, download a Ryzen master, it can.

    Temps haven't gotten higher than 75C (set my aura to turn red at 75). I'm very certain my cooler is properly mounted. I've been monitoring with HW Monitor. I'm on my 8th minute of Prime 95 (after swapping PSUs as vapour suggested). I'm at 52 C. I'm hoping this is the solution.

    I've been running Prime95 for 30ish minutes (twice as long as my previous best). I think the psu was the issue. Thanks so much! If it's not, I'll let you know, but this is the first time I've had any sort of stability while testing.

  13. Congrats! What budget do you have on PSU? I can recommend a good one :)

    Update: After receiving and installing my new psu, and then updating my chipset driver, I started having issues again just as before. I reinstalled my other power supply and had similar issues. After more research, I decided to uninstall Aura Sync because multiple other people had issues with the program causing instability. After reboot, I ran Prime95 for 4 hours at default bios settings. I'm feeling better about it now. I'm assuming that the current chipset driver doesn't like Aura Sync. Hopefully this can save someone time and headache in the future. Thanks once again vapour for helping me out.
