Prime95 fail after OCing

Ok, so I have established that Prime95 runs perfect on Small FFTs, but will stop working on Large FFTs and Blend. I am @3GHz with stock voltage and no change to the RAM.

The RAM got confusing, it was giving me way too many options and even if I tweeked them nothing changed. My RAM is 5-5-5-15 :( @1.8v and is 2x400MHz. Also, there seems to be no option at all the reduce or even change the HyperTransport multiplier.
 
HUZZAH!

I have it stable at 3.00GHz at last! :D

I used these values:

FSB Clock : 231
CPU OverVoltage : Auto (Have no idea how that worked?!)
Mem Clock : 333MHz (Actually shows as 385.0MHz in CPU-Z)
Mem OverVoltage : Auto (Once again, how does this work?!)

So bizarrely this works for 3.00GHz...

It isn't a massive clock, it's about 20% but it is good enough for now. I am running stock cooler anyway and only reaching 49c AT MOST on Prime95 Blend. usually fluctuating around 36-38c.

I am going to try to get a stable 3.20GHz next. Wish me luck.

Also, when I decrease the Mem Clock the Memory Timings get lower (better), is this supposed to happen?

Thanks for those who helped. :D
 
Prime95 has been running for 3 hours now, I heard that it can get problems at 5 hours and then from there you should get no problems, after it's done 5 hours I will post back here.
 
Auto is ok for using std clocks..using auto and overclocking can lead to dead pc as you have no idea what volatge is being pushed. It may run fine for a day,week month etc but it will go pop with auto settings :D
 
I have not been updating this because eventually it would look like spam. I don' want it to look that way.

These are what I have at the moment:

CPU FSB Clock - 255 MHz
CPU Multiplier - 13x (4 Cores)
OverVoltage - 1.4v
MemClock - 255MHz (Underclocked for increased CPU Stability)
Mem OverVoltage - Auto
MemTiming 5-3-3-9 2T
HyperTransport Frequency - 2040MHz

I am getting 3.315GHz which is 30% overclock. It is stable in accordance with Prime95 and I get load temps of 61c maximum. I am going to test how low the voltage can go plus staying stable just to reduce heat.
 
Above post is wrong, completely.

I am at 3.4GHz now, read my sig.

QUESTION:

Prime95 been running for 2 hours now but different workers are on completely different stages, it this supposed to happen?
 
Blue Screen exactly on the 2 hour mark.

Prime95 displays no error messages in results.txt so I assume it didn't have enough time to record them down, unless it was some other unrelated error.

QUESTION:
I have been running Prime95 and Firefox for the whole 2 hours, are you supposed to run Prime95 on it's own?

After 5 minutes the Worker 2 and Worker 4 failed at the same time, even though my CPU was at 42c and Mobo at 38c (according to PC Probe).

Thanks in advance.

Eek, do not use PC Probe if you want accurate temps. Its notoriously unreliable and only takes a case measurement of the temperature. Use coretemp or realtemp if you don't want a smoky computer.

I will try them out, thanks.
 
Posponing the overclocking until I get a proper CPU cooler as my comp bluescreens at 70c+.
