Hi. Today i checked my event viewer and found some weird errors in 21.01.2018 :

System Warning 21/01/2018
A corrected hardware error has occurred.

Reported by component: Processor Core
Error Source: 1
Error Type: 9
Processor ID: 0

Here are screen:

Its only in 21.01.2018 day. I remember that system was idle in night this time.

Ok my pc:
8700K stock, MTU on, 4700mhz auto
Asus Z370 Pro Gaming
16GB DDR 3000MHZ ( XMP )
Corsair 750i
SSD Crucial 525GB
HDD TOSHIBA 500GB
Windows 10 clean install 1709 Creator Fall Update

Temps of cpu fine,temps of gpu fine. Never had any single BSOD. Memtest86 no errors. All benchmarks passing, no crashing in games

. Only saw that error in event viewer which make think that is still with cpu or what?

If it doesn't occur again, I wouldn't be overly concerned. When overclocking, however, WHEA events are normally related to insufficient vcore or memory instability.

To test memory stability on DDR4 platforms it's recommended to use HCI Memtest Pro, as Memtest86 doesn't load up the memory bus on modern platforms in any meaningful way.

Test with one instance per CPU thread, dividing 80-90% of available memory across each and leave for 400% coverage.

Ok but where to change nstance per CPU thread, dividing 80-90% of available memory across each and leave for 400% coverage. ? I see only button TEST MEMORY

You need to open multiple instances.

If you purchase the Pro version, you can use this launcher courtesy of Frikencio via OCN.

Ok so to how much open this memtests windows and what amount of ram enter to each?

lpiotrowski211 · ‎02-01-2018

Ok i put 12 windows with 1200mb memory its fine?

Silent_Scone · ‎02-01-2018

As I said above, open one instance per CPU thread, so that's 8 instances for 8 threads. Divide 90% of available memory between each of them.

I am running with 12 windows and 1200mb each ? its ok too?

Silent_Scone · ‎02-01-2018

Yes that will work, but easier to run with the number of threads as suggested.
