BSOD while playing, ntoskrnl.exe

Just now, while playing BF3.exe (always god damned BF3)..

Code:

BugCheck 3B, {c0000005, fffff80002af0980, fffff8800a0d16b0, 0}

Probably caused by : ntkrnlmp.exe ( nt!KeClearEvent+0 )

Code:

Usual causes:  System service, Device driver, graphics driver, memory

This bugcheck can also be due to page pool errors, graphics card and malware.

Code:

0: kd> !error 00000000c0000005
Error code: (NTSTATUS) 0xc0000005 (3221225477) - The instruction at 0x%08lx referenced memory at 0x%08lx. The memory could not be %s.

Please run the following tests for your graphics card:

Graphics Card:

• Video Card - Stress Test with Furmark

Read all the steps within the hardware test tutorials very carefully, as stress tests is designed run components to their maximum capacity, in order to point out failing or faulty hardware components.

Use the following program to monitor your hardware temperatures during the stress test:

• CPUID HWMonitor

Test the Power Supply/Video RAM -

• NVIDIA/AMD Video Card - Test with OCCT

I get 88 degrees on the power supply test, no errors in memory with the OCCT (10 passes). Ran for 15 minutes, as it was quote: "very intensive on power supply".. posted pics with the diagrams.. Looks good. I've stresstested with Furmark before, similar results ~ 88-89 degrees C ..


The GTX680 I have is a non overclock, reference design..

Also, yesternight I tried playing around some with the voltages of memory and the vcore of the CPU, first I tried increasing RAM voltages from 1.5v to 1.65, made me crash into Windows after 5 minutes of play. Removed SpeedStep and some other intel setting on the mobo, aswell as increasing vcore with .01 volts, after some reading on a different forum. After that I could play uninterrupted for the rest of the night. I will get into a game now and see what happens.

Did you change the DRAM voltage settings? The highest recommend value is 1.6v and no higher.

Yes, but switched back since it was no good.. they are now back at 1.5v

What is your PSU brand? You could try increasing the VccSA and VccIO voltages slightly to about 1.100v and then the DRAM voltages to about 1.550v.

I have a Fractal Design Tesla,650W..

• GeForce GTX 680 | Specifications | GeForce

Change the voltages and then report back the results.

well I haven't had any crash since vcore increase.. Do you think I still should increase vccIO/SA + DRAM?
also, I'm not sure what you mean with the nvidia specs? :)
