Recently I update Windows 10 to version 1903. There is no BSOD now: Large Pages Test 19.05 (x64) : 2019-02-11 Windows 10.0 18362 RAM size: 16341 MiB Intel(R) Core(TM) i5-3330 CPU @ 3.00GHz (306A9) 1 GiB pages: - Timer Freq = 10000.00 kHz CPU Freq (MHz): 3080 3394 3416 3424 3426 : 3426 Size Address Alloc Zero Random-Fill | Latency-64 | Latency-128 bytes ms ms % % ns | ns ns | ns ns 16k 00800000 0 0 602 99 7.16 1.17 1.17 1.17 1.17 20k 00800000 0 0 601 99 7.92 1.17 1.17 1.17 1.17 24k 00800000 0 0 604...

I became very interested in testing this issue on my system. Now I am looking for the exact crash conditions on my system. I have run "large_pages.exe 4096 s5 z27" several times without crash. Could you add cmd parameter "start block size" for faster search after 4096 boundary?

My assumption was wrong: 15 min uptime 4096 - Ok 5120 - Crash Task Manager: committed 2.0 Gb + cached 2.5 Gb = 4.5 Gb

Without log file: 1) 2 min uptime (after 1st superfetch aka "SysMain") 5120 - Ok 6144 - Crash Task Manager: committed 1.5Gb + cached 0.9 Gb = 2.4 Gb 2) 8 min uptime (after 2nd superfetch aka "SysMain") 4096 - Ok 5120 - Crash Task Manager: committed 1.8 Gb + cached 1.2 Gb = 3.0 Gb It seems that crash occurs when used memory is more than 8 Gb.
