Yup hate to say it but that can be the culprit pia - do I buy a new one or not - nice to have one kicking around to check it - forgot about that 

I should have considered the PSU first after changing RAM, Liquid Cooling etc....would have saved me alot of nerves and money. 😄

I haven't overclocked anything. Are you talking about using MSI Afterburner to bring the GPU down a little? Thank you for your response. 

The question is if your CPU is even clocking that high (up to 5.1) considering your low-grade watercooling and 750W power supply.

Like someone else said, I would suggest checking system stability with some tool like Prime95 or AIDA64 and check your temperatures, voltages, things like that.

I'm not an expert. But i had similar problems running alls sorts of games. CTD and/or Bluescreens at totally random timings. Tried everything i could. It finally turned out that my PCs PSU was causing issues. Replacing my 700W PSU with a 850W resolved all issues completely.

Im running an i9-9900k @5.1GHZ along with an RTX3080 etc....

 

Just a thought.

Yup. That would be my guess too. Even it's got enough power on paper they fail over time. Especially the cheap ones.

Have you checked  that your RAM and cards are well seated in their slot and that every connection inside is tightly secured (into the PSU etc.).

I highly doubt that will it will be your RAM XMP settings. Removing the XMP profile in the BIOS will only throttle the entire PC.
More chance of it being your PSU than RAM XMP.

I suggest a more pragmatic approach. You are running everything on Ultra graphics settings? Change everything to High and do a test flight again. Hop in the A320 with live weather and all AI air traffic turned OFF. Do a 2 hour flight between 2 detailed airports. Don’t go surfing the web or doing other stuff on the same PC while doing this flight.

Clear your community folder. Does it still CTD then?

I just had a closer look at that system integrator @Bdub22mentioned, https://jetlinesystems.com/ .

It has the typical red flags of other prebuilt gaming PC system sellers I already mentioned in other threads.

• Putting in power supplies that might look good on paper (750W) but are only gold rated and don't even say what type they are exactly (could be really cheap ones).
• Putting in low-grade AIO watercooling solutions with only one 120mm fan because the customers think that's awesome when a cheaper but high-quality air-cooler would be the better solution at a lower price point.
• Not specifying the exact RAM configuration (only says 32 GB Corsair 3200)

It's always the same story, be careful when buying prebuilt systems that look good on paper, people!

As stated above, 750W for a 3080 is bad news. The thing is an absolute pig. A high quality 850-1000W would be recommended.

I'm pretty confident my system has randomly crashed a couple times due to spikes in GPU power draw and I have a pretty nice platinum corsair 850W. Part of me wants to upgrade to 1000W so I don't have to deal with it.

I think, if the OP has the option to change to a different and better rated PSU and see if it helps in any way, he should go for it. Maybe i was lucky but the PC dude i usually have my systems built by, had a PSU around, installed it and let the PC run for some time including benchmark and so on. After an afternoon with no issues we decided to install a fresh PSU (BeQuiet! Straight Power 11 850w Platinum) and since then i have never seen any CTDs again.

Best regads,

Tom

This isnt necessary .. What is necessary is a QUALITY PSU.

750 watts is not an issue for a 3080 .. What i want to know is whats the make and model of the PSU presently in the system .

Have you run any strong gpu  benchmarks in a loop ( 3dmark  Timespy or port royal ) ? or  run Heaven maxed out and monitored the system with hardwareinfo64 to look at the power draw and heat ?

I use GPU-Z to watch GPU and the 3080 does pull a lot of power.

You should download it and run it as you do a flight. Click the second tab, drag it open to your full screen width and have a good look at everything.

Money is well spent on cooling and power.

I use

Corsair iCUE H150i Pro XT 360mm •

Corsair HX850i Platinum Plus 

Not only are the two above good, you cannot even hear them.

Edited July 13, 20214 yr by Nyxx

So your PSU, 750 watts is fine and actually recommended by Nvidia,  but yours might be faulty.

testing the system, memtest and prime95 won’t test the GPU.

issues like this are a nightmare to diagnose and sometimes you have to bite the bullet and make a change - honestly I would just replace your PSU and try again.

Other than that and looking at your system, you could pull that sound card to eliminate that - it’s unlikely to be the cause though.

and if you're using XMP memory profile try disabling it in BIOS and see if that helps.

This was the FIRST change I made and the ONLY change I made. I've literally been using MSFS like I've been begging to for almost 3 months now. I was skeptical it was just a coincidence at the 3rd hour mark, I kept on knocking on wood. But, after almost 6 hours of straight usage, I think that quick fix did it. I tried all types of weather, AI Traffic configs, WT G3000 and TBM Mods, in Paris, NYC, even in word not allowed weather I could only fly in before for 5 minutes. As I said, those hours were so enjoyable that I'd hate to jinx it, but I think somiller had it just right. 

I'm just curious, as I've read on up on it a little bit, but it's crazy one little setting caused all that fuss? Although, I've been around Flight Sim long enough to know how fickle this software is and has always been, it's just crazy to me. 

I'll definitely take into consideration to everyone else's suggestion, especially with power unit and cooling, and memtest, et al. All great ideas.

Thank you so much again, everyone. 

Double Post. My bad

Edited July 13, 20214 yr by Bdub22

One last thing to check, is your BIOS up to date?

Bdub22,

I mentioned XMP because when I bought EXPENSIVE Corsair Dominator Platinum 2400, C10 memory a few years ago I had all sorts of trouble with stability when using the XMP profile. P3D would crash, couldn't run Prime95 more than a few minutes, and even had BSOD's. As a matter of fact, when first enabling XMP, I don't think my system would even boot - I had to fiddle with voltages and a few other settings in BIOS to finally get it stable, but I would still experience a rare P3D crash or BSOD.

With all that said, I believe my XMP issues were a combination of XMP and CPU overclock instabilities, and it took a lot of effort to find the right BIOS settings to make XMP and O.C. work together.

If you're going to try XMP again use Prime95 to test stability. I don't remember which test battery I used to run, but one of them is a very strenuous memory test and it will really heat things up. I found that if there are instabilities, you won't have to run Prime95 very long before it will crash.
