So I started having this issue after overclocking my CPU. The system would randomly turn off during idle. Never during prime95 or gaming. *click* and the whole system is off. At first I thought it was the PSU, so I swapped it out. No dice this PSU was having the exact same problem. I started getting ready for a refund on newegg for the MB and CPU. Then I decided to try one last thing. Turn LLC off. It worked!Kind of
LLC level 3: upon booting windows instant shutdown
LLC level 2: shutdown usually within 5 minutes on idle desktop
LLC Auto: No shutdown
bios 0502 LLC 3: random shutdown after 8 hours idling
Bios 0502 LLC Auto: to be seen
None of these shutdowns happen while gaming/prime95 for hours and temps are not a problem.
Can anyone test this? PLS
r7 1700 Bios 0504
3.7 ghz, 1.3v, LLC level 3. Just sit on the windows desktop for an hour and see if the system turns off.
