brand new build PC Rebooting during game play Max XI Formula

[MaLLoc]

i have been playing just fine and all of a sudden while playing a game ( BFV ) it rebooted on me , then again 3 hours latter during the game. the CPU was at around 55 and GPU around 59 , the PCH was at about 67 , nothing different then when i had no rebooting , i have had it even hotter specs in other games.
the Memory had XMP on at 3200 , the CPU had Turbo on at 4700 , Fans where runing at about 80% to 100 % water pump was running at 2300 -2600 and i have 8 pin CPU Motherboard power plugged in and NO power on the 4 pin next to it, all for over a week with no problems. the system is about under 2 weeks old

My son's system was doing random reboot few month ago. I went through trouble shooting like you were doing. Thought it was CPU, Memory... blah...
But as it turn out in the end, it was my Corsair AX850i power supply with digital power correction that was causing the issue. RMA my AX850i... and they send me AX1200i. Violla... problem solved.... no more random reply.

Point is, don't forget to check power supply. It maybe defective. If you have access to another power supply. Swap it out and check.

yes that has been on my mind , however have no problems rebooting anymore , now i just get sudden pc blackout , no monitor and no pc reaction even though all system is powered and fans going , you can hear the sudden power drop though when the monitor blinks out , and this happens now every few minits trying to play a game of battlefield 5 , but strange enough i went and played a whole round of battlefield 1 and nothign happend , maybe a fluke idk , ill try playing it longer to see if i get blackout , i ran benchtest for a short time and nothing happened to the pc while it was under the test load , so im at a total loss so far

The way to rule out PSU problems is to swap yours with a new or good borrowed one. What were the results when you did this?

Have you run the system continuously at stock as requested several times in this thread?

yes i have stated that i turned everything off no turbo no xpm , i get no reboots, but now i get system failer blackouts when i try to run a video game , but i didnt get any failer yet when trying a bench program , and i havent been able to boot onto a USB to do out of windows memory test on this motherboard , its extremly iritating

okay replaced the PSU with another one , exact same model 1000W seasonic 80 plus platinum certified had 2 systems with same PSU, and system blacked out again on game launch , also i took out 1 stick of RAM and tried and then the other , both sticks speratly the system still blacked out, getting worse , now it just blacked out with only web pages open

turns out it was the Video card failing and just getting worse as i kept trying to run a game, dont know why turbo clock or XMP would make the pc reboot on card failer then when off just made the computer go blank, anyhow , stilol need to figure out why i cant boot into a memtest on usb

Are you sure you are using the UEFI version of memtest86?
Do *NOT* use memtest86+.
Booting to memtest86 is extremely easy.
1) install UEFI version with their installer (hell you can even download Rufus yourself and point it to the memtest86 IMG file and install it that way too, if you're a purist).
2) insert your memtest USB into a usb drive.
3) boot to bios and change boot order to boot from the USB drive first, before the windows boot manager (SSD or HDD).
4) that's all you have to do.

As already posted, memory instability can cause sporadic reboots. I would run the tests I've already recommended as Memtest86 is not going to tell you anything worth knowing regarding stability. Both HCI Memtest and Ramtest are far more stringent.

i am not saying this is the problem
But in gaming and 3D benchmarking when the system reboots under load, its very often too low vcore
Its like a trait or signature, i am sure most hardboild 3D benchmarkers can agree

first step: I would load setup defaults in bios, and try the game (if it fails)
if the game wont fail, then you will know where the problem is (bios settings)

(sorry, i did not read all posts in this thread)

Good luck

The OP has already removed XMP which has resolved the sporadic rebooting 😉
