Crash once or twice a week

[ShockSA]

Hello, I have a problem and it's driving me insane, I keep getting a random BSOD once or twice a week and I didn't find any solution for this, I tried memtest+ and prime95 my CPU, stress test my GPU and all is fine, the BSOD is really random sometimes when I'm watching a stream or playing a game or simply browsing, any help is appreciated.

p.s. : nothing is overclocked, only GPU is factory clocked.

My System specs:
CPU : i5-4670k
GPU : GeForce 680 GTX
RAM : 16GB 1600hz Kingston
MOBO : Gigabyte Z87x D3H
PSU : Antec 750W

I uploaded the memory dumps to Mediafire :

edit #2 BIOS reports that your CPU is at 1.1V this might be too low (BIOS update or set the value directly)

Status Enabled Populated




edit: forgot to mention: you could also get this if the voltage to the processor is too low. (power issues)
each bugcheck showed cache errors on different cache memory banks:
GCACHEL2_ERR_ERR (Proc 1 Bank 5)
GCACHEL2_ERR_ERR (Proc 1 Bank 7)
GCACHEL2_ERR_ERR (Proc 3 Bank 5)

this is why i suggest that your cpu may have a low voltage. if they were all the same cache bank it would be a cpu cache memory error.

I would do a BIOS upgrade, the BIOS will control the voltage to the CPU



CPU reported a error in it cache windows produced a bugcheck in response:
CPU generated cache error is hard to help. I would look for heat related issues
maybe:
- underclock cpu
- check for overheating, dust on fan/cpu cooler
- update BIOS to get CPU microcode fixes
- you might be able to disable the cache but CPU would run slowly
- you might be able to disable a core, or tell the OS to run on one cpu by setting the affinity

all three bugchecks had the same root cause

debug info:

So should I overclock the CPU or get a new PSU? also im running the latest version of the BIOS , should i set the Vcore to 1.25? or 1.2?

 

[johnbl]

edit: 1.2v vcore should be fine for i5-4670K, give it a shot for several days and see if you get a crash. is so post the crash again.
edit #2 the power supply basically will supply, 3.3v, 5v and 12v the lower voltage would be regulated by the motherboard
and I would expect that a power feed would have to fail or realy fluctuate to cause a problem.

The voltage reported in the crash dump may not be correct, I would not get a new PSU, but would increase the power to the CPU slightly just like you were doing a slight overclock, but don't actually overclock the CPU, just increase the voltage and run the system for a few days and see if you get the same crash.
What I saw in the debugger was voltage 1.1v, I can not see what you see in your BIOS, they could be adjusting the numbers or telling the OS a hardcoded number.
So find your BIOS setting and increase it by a small amount, something like .05 volts and retest.
You might also look up what people that overclock actually set their VCORE to. (just to find a safe range of values)
(It has been years since I have done any real overclocking, so I don't feel I can give good advice on the voltage)
I do however feel that your problem is well explained by overheating or a low core voltage. (cpu cache failures all in different memory banks in the cpu cache) if they were all the same cache bank then I would think it was a fried memory location in the cache (not the case this time)

So should I overclock the CPU or get a new PSU? also im running the latest version of the BIOS , should i set the Vcore to 1.25? or 1.2?

new crash after bumping the cpu voltage to 1.25

also my cpu temp never went above 62c on prime95
also i found F8d beta bios update in the notes it says :
Fixes:
- Improve system compatibility
should i use beta bios?

error looks like the last but cpu 3 cache bank 5 had the error.

your OS binaries in memory did not show any corruption.

I would try the beta BIOS and see if that helps, be sure to grab any intel chipset updates
if neither of those fix the issue, it is looking like a cache error inside the cpu.

Thank you , updating the bios to the beta version fixed the problem , cheers.
