[BSOD] Which Hardware part is it?

Hi

I have some strange issues with my computer

I have my computer since 20months, since I build it I have some BSODs while gaming or watching video.

Yesterday I bought new RAM which is official supported from the mainboard.
After I replaced my old RAM with it I had MORE Bluescreens (3 times while playing sc2, 1 time after some seconds of prime95)

The BSOD

Code:

BugCheck 124, {0, fffffa800686b028, fa000000, 400405}

Code:

0: kd> !analyze -v

A fatal hardware error has occurred. Parameter 1 identifies the type of error
source that reported the error. Parameter 2 holds the address of the
WHEA_ERROR_RECORD structure that describes the error conditon.
Arguments:
Arg1: 0000000000000000, Machine Check Exception
Arg2: fffffa800686b028, Address of the WHEA_ERROR_RECORD structure.
Arg3: 00000000fa000000, High order 32-bits of the MCi_STATUS value.
Arg4: 0000000000400405, Low order 32-bits of the MCi_STATUS value.

Why does it show VISTA_* I run WIN7
Can someone say which Hardware Part is causing the BSOD?
The RAM should be fine, same errors occurs with old Corsair and new Kingson RAM
Temperatures are OK.



Don't hate me for that, but I using Linux too (I know thats the wrong place here, but I attach it too)
Probably helpfull for some, Linux gives some readable error message
The errors occur when I run memtester linux programm)

After these errors the system does not have to reboot, sometime it runs for some seconds/minutes and freezes then


Is it the CPU which is buggy?

P.S.
Prime95 Blend Test results in the bluescreen after some seconds
MemTest86+ 4.1 shows no errors (2 passes)

usasma said:

Try Prime 95 using each of the tests (Small FFT, Blended, Large FFT) - no need to repeat whatever tests you've already run. Let us know the differences in time to crash.

Have you checked the motherboard website to see if your RAM is compatible with the motherboard?
Have you visited the RAM manufacturer's website and found the settings/timings/voltages - and then gone into the BIOS and set those settings/timings/voltages? (In other words, DON'T use the Auto settings for your RAM)?

Small FFT didn't resultet in BSOD
In-place Large FFT results in a BSOD within 2/3 minutes
Blend, max 15 seconds until BSOD


RAM is official supported by the Mainboard
Timings are set manually (9-9-9-27 / 1 @ 1.5V)
auto settings would be something like CL7

CPU Stability Test runned for 30min in normal mode before a BSOD
Second time it runned 1h 30min without a BSOD

Thermal Mode doesnt result in BSOD (only 30min tested because temps didnt went high ~50deg)


I have the BSOD too with only 1 stick in 2 separate slots
I will run MemTest this night and report the result back
