My Pc just crashed:

Here are the error messages, from the event viewer, and from a message from when windows started up.  What does the 9c, error mean, and what settings do I need to tweak.  I hop I don't need more vcore.  Let me know.  Thanks:

BCCode 9c Useually means its a machine check exception. It may be caused by faulty CPU, Mother Board, or RAM.

I had to go to a Vtt of +250 on my system, and needed a CPUV of 1.375; regardless of what you try, Dont go above 1.4 or +300, as that will take you out of the safe range. also look at your temps, No core , or anything else for that matter , should ever go above 85,  with IBT or LinX, and some use 75 as their guide.    

9c is straight up vcore. Your cpu isn't getting enough voltage to handle load.

9c will usually "become" 101 code.

Did it go away after going up a notch on v-core? What are your full load temps now? If you get water cooling, you will be able to go up more. Not all 920 DO's are voltage misers. Also, once you get temps down, don't be afraid to go over 1.4 volts on your v-core. It won't hurt a thing.  At your 196 X 20 (which is actually 21 with turbo enabled) you are over 4.1 ghz. I feel that your v-core is just too low to handle it.

I upped vcore 1 notch from 1.3125 to 1.31875.

The following recorded temperatures are with my room temperature at 78 f.  With the Outside temperature at 101f, my Wall Unit Air Conditioner at the lowest (60 f Full Fan) setting is unable to lower the ambient temperature any more.

With the cores Idle, (0% cpu usage) CPU-Z reports a vcore of 1.329.  With the idle cores, the core temperatures are:

62 c
60 c
59 c
60 c

After having been at full load (each core between 99 - 100%) for 10 minutes, CPU-Z reports a vcore of 1.364, and the core temps are:

91 c
91 c
85 c
86 c

These are high with MY A.C. Blasting.  I took the liberty of keeping the A.C. on while I was at work today.  The problem is that with my setup, with every degree increase in ambient room temperature, my core temperatures increase the exact number of degrees.

With Vdroop Off, the maximum vcore is always more than the bios setting.  I did notice the change.  With the older 1.3125 vcore setting, at full load, CPU-Z would report vcore between 1.352 and 1.364.  Now, with the setting at 1.31875, CPU-Z always reports vcore at 1.364.

sgtharry  - You had mentioned that my vcore was too low.  What would you consider appropriate to handle my overclock?

Thanks.

I prefer to keep my overclock.

Please reply with suggested water coolers.

Thanks

You should ask that Q here:

Overclocking, Cooling and Benchmarking

And think system components, not just a single-part solution.

Is this CPU Cooler designed for this much vcore, when the Ambient Temperature is 78f?

CPU Cooler (Thermalright Ultra-120 Extreme RT 1366 58468-Q Kaze Jyuni SY1225SL12SH 120 )

I used some sore of "thermal pad" instead of paste.  Some posters here have criticized this.  I'll take a look at the "fit."

It was working great while my vcore was <1.3 and the outside temperatures were <85 f.

My core temps went up a little with the new vcore of 1.31875. At full loads, CPU-Z mostly shows a Vcore of 1.376, and sometimes 1.364  Now, at full load, (still room temp at 78 f) I have:

94 c
93 c
88 c
88 c

I earlier tied a personal record with 98 c on 1 core!

I'm curious as to why cores 0 and 1 are always a few degrees higher than cores 2 and 3?
