WHEA Event ID 19 CPU-corrected hw error / i5 4690

[LFark]

Dear Members,

I found the error below in Event Viewer.

Should I change something in UEFI? (memory profile, speedstep, filter PLL?)

No BSODs, only 9 warnings after 8 days.

When last time occured only downloaded a cd, maybe did sha1 calc, no gaming or other intensive task.

MciStat 0x90000040000f0005

Found something:

Vol. 3B 16-3

INTERPRETING MACHINE-CHECK ERROR CODES

Table 16-4.

Incremental Bus Error Codes of Machine Check for Processors

Based on Intel Core Microarchitecture

Bus queue request type error

bits 19-24

000001 for BQ_PREF_READ_TYPE error

But what does this mean? google "BQ_PREF_READ_TYPE" -> nothing

Is it important? Helps to determine the source of the problem?

System:

MB: Asrock Z87 Extreme4 / BIOS: P3.00 - latest

VGA: in cpu

HDD: 2 WD SATA

+ 1 DVD RW with IDE->SATA converter

OP SYS: Win 7 SP1 x86 + WSUS updates up to 2014.10.14

This is a mysterious bug:

"I have now tried different motherboards, CPUs, memory, and power supplies and

this error is still showing up now and then.

This points strongly to either FreeBSD bogus reporting, or these errors being

benign. It's hard to believe that the exact same error might occur with

completely different hardware ... unless it's being caused by the case."

I would reset BIOS settings back to defaults or check if the voltage values are ok.

Dear Joe,

Ok, I did a reset.

10 settings changed / E-Enabled, D-Disabled, A-Auto | in ( ) my previous non-default cfg

+ manual info

01 E (D) - MRC Fast boot | skip DRAM memory training for booting faster.

02 A (D) - CPU OC fixed mode / allows you to keep the max CPU ratio as your setting without throttling.

03 E (D) - Intel Turbo Boost / enables to run above its base operating frequency when the OS requests the highest performance state

04 D (A) - Package C state / CPU, PCIe, Memory, Graphics C State Support for power saving

06 PCIe (Onboard) - Primary Graphics Adapter | don't have a card, so changed back to Onboard

07 D (E) - VT-d | supported by CPU > Intel® Virtualization Technology for Directed I/O

08 D (E) - IGPU multi monitor / Select disable to disable the integrated graphics when an external graphics card is installed.

Select enable to keep the integrated graphics enabled at all times.

09 D (E) - HDD SMART

10 By OS (D) - RTC alarm power on / Allow the system to be waked up by the real time clock alarm.

Set it to By OS to let it be handled by your operating system.

Also changed from default in the current config:

Setup prompt timeout -> to 15s

Full screen logo -> D

Unplugged the IDE<->SATA converter of the DVD drive to minimize possible error sources.

Now I have 13 event, I will report back if increases.

Hello,

I think I found the solution:

Desktop 4th Gen Intel® Core™ Processors Spec Update

2014.10 Revision 018

http://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/4th-gen-core-family-desktop-specification-update.pdf http://www.intel.com/content/dam/www/public/us/en/documents/specification-updates/4th-gen-core-family-desktop-specificat…

HSD131. Spurious Corrected Errors May be Reported

Problem:

Due this erratum, spurious corrected errors may be logged in the IA32_MC0_STATUS

register with the valid field (bit 63) set, the uncorrected error field (bit 61) not set, a

Model Specific Error Code (bits [31:16]) of 0x000F, and an MCA Error Code (bits [15:0]) of 0x0005.

If CMCI is enabled, these spurious corrected errors also signal interrupts.

Implication:

When this erratum occurs, software may see corrected errors that are benign. These

corrected errors may be safely ignored.

Workaround:

None identified.

Status:

For the steppings affected, see the Summary Table of Changes.

And my MciStat 0x90000040000f0005

F and 5

9 = 1001 -> 63=1, 61=0

+ found a comment here:

Now not important:

Got another one with default BIOS settings

I did a 10 min test with Intel Extreme Tuning Utility v5.1.1

Here you can see some voltage info:

The PSU seems stable (as I expected):

I know that my unit could be different/faulty, but I don't have a multimeter to back up further the AIDA results.
