FATAL ERROR, can somebody explain?
Hello,
i've got a MSI P45 Board here with a Intel Q9650. I thought i am done with overclocking but,... At first i've used 20484096k FFT for checking out Northbridge, FSB and Ram (FFTs not inplace): 24 Hours no Error. After that i used 816k (FFTs inplace) to check the CPU: 24 Hours no Error. At last, i've done a 84096k FFT inplace test to check everything at once. I got an Error after 24,5 Hours. Can somebody explain me if the error i caused by Northbridge, FSB, Ram or by the CPU?

maximum load CPU Temp is 71°C (+/ 1°C) (TCASE by Intel is 71.4°C)
Northbridge and Ram have no Temp sensors, but they are just warm. I can touch them easily with my fingers without getting burned. So i guess below 50°C. Last fiddled with by Nils on 20120720 at 10:16

My guess is RAM, but it is purely a guess.
If you aren't going to use your computer for CPUintensive work like GIMPS, SETI, Folding@home, etc. then I'd say you are stable enough. Otherwise, I'd back off the memory timings a hair or up the voltage a tiny bit and try again.

Now i'm running another 84096k run.

Well yes, but as I recall in one of the iterations of v27, you removed the 'type3' message because almost all production FFTs are of that type. Thus I was asking, the lack of a type identifier means that it's type3?

You are correct. If prime95 doesn't specify a type, it is a type3 FFT  not that that means anything to anyone but me.
