Hello - hope you can help me to identify the faulty component in my system.
CPU: i7-2600K
MOBO: ASUS P8P67 Deluxe REV 3.0
RAM: 4 * G.Skill F3-10666CL7-4GBXH
PSU: STRAIGHT POWER E8 550W
HDD: OCZ Vertex 3, OCZ Vertex 2, Seagate Barracuda 7200.13 3TB
GPU: MSI Cyclone 460 GTX OC
So my system was running in the night for folding@home. In the morning when I switched on my monitor I saw the BIOS logo and after pressing reset it wasn't booting anymore. I did CMOS reset and loaded default settings - booted windows and played BF3 - after some time I got a BSOD 124 - reboot and play again BF3 after some time again 124 and sometimes later 9C.
I did 15 hours of Memtest+ via USB stick - no errors.
Shut down the system and went to university - somewhen at the next day it even does not start with default settings.
So I deactivated Turbo Boost and set max speed @ 3,2 GHz - deactivated XMP and fixed vcore @ 1.07 V (currently running with this + in background Prime95 small FFT for about 45 minutes till now).
If I try to run the same speed and fixed vcore with auto setting or auto offset+ it fails with BSOD 124 or it even freezes in/before BIOS with qcode 64, d0, 72, b2 and some others and sometimes BOOT_DEVICE LED on or GPU LED on.
Before all this my system was running stable for more than half a year with this settings:
CPU @ 4,7GHz HT SpeedStepping TurboBoost
vcore offset+ 0.145
dram 1.5V XMP timings
vccsa 0.875V
vccio 1.18125V (I know it's a little bit high but till 1.2V should be okay..)
cpu pll 1.675V
pch 1.00V
llc ultra high
vrm manual 350
phase control exteme
duty control extreme
cpu current capability 140%
with some more vcore it was even stable at 5,1GHz
I will try to borrow an other PCU with maybe some more power (but 550W should be enough) to eliminate this component.
I will try to only use one RAM stick. (but quite sure it is not the RAM since memtest+ run 15 hours..)
Unfortunately I have no 2nd board to test CPU/MoBo :S
GPU has no errors @ MSI Kombustor even when 50% overclocked
Temps are also not the problem - 4,7GHz with synthetic load was @ max 80°C / 176°F
So what do you think could be the faulty component - or what should I do to determine it ?
please help me
