I've been getting this stop code when running Prime, and I can't find squat about it online. Any ideas?

0X1
STOP error 0x1 means that there has been a mismatch in the APC state index. STOP code 0x00000001 may also display "APC_INDEX_MISMATCH" on the same STOP message.

Did you change anything?

Can you post your OCing info / bios data?

Still randomly getting this error...

2 letter bsod codes generally mean that more vcore is required. is your computer even stable to start with?

I ran 50 passes of LinX with no errors... I'd say it's stable. There doesn't seem to be any rhyme or reason to this error. I was just browsing the net through Firefox last time it happened.

 

[Allenssmart]

ok that's very stable under load.

1. Do you have load line calibration enabled?
2. Do you get the bsod under intense cpu usage (gaming, video encoding) or during idle (word processing, firefox, email) ?
3. download cpu-z. what is the vcore on cpu-z?

Load-Line Calibration is enabled.

The BSOD is very random and has happened only 3-4 times. Sometimes under load, and sometimes at idle.

My overclock is a bit different than I listed above. Here are my current settings:

21*180=3.78GHz
QPI Link Speed - 6.48GHz
Uncore Frequency - 3600MHz
Memory Multiplier - 10.0
Memory Frequency - 1800MHz
Timing - 8-8-8-20 1T (tRFC 64)

Load-Line Calibration - Enabled
Vcore - 1.250v (1.232v in CPU-Z)
QPI/VTT Voltage - 1.395v
DRAM Voltage - 1.50v

**** DUDE! i think i might know the problem, just maybe. your qpi/vtt voltage is WAYYy to high, and wtih qpi/vtt, high voltage may cause just as much INSTABILITY as low voltages. try lowering that to like 1.25, it's really WAY too high. if it's unstable at 1.25, slowly go up. i'm almost sure that's it.

I've been through this before. It's not the QPI. It's totally normal to need a higher QPI/VTT voltage when running ram at higher frequencies. I have my ram running at 1800MHz.

A G.Skill support technician told me that to run at 2000MHz, a QPI/VTT upwards of 1.6v may be needed. That's a little too high for my liking, so I cut my RAM back down to 1800MHz.

Have you tried any of the suggestions posted here?

Just in case anyone else is getting this BSOD for no known reason, I found a solution:
