i am really interested in the PWM temps you got from the board, its just i had my AX78 running at 1.55v vcore, and the temps went through the roof.

under load they were hitting 80- 90 degrees C,

even i know that this would be cool for around a week or so maybe, and then the board would have probaly started the random shut off thing.

thinking on that, what would you say the Max temp for the pwm would be? i allways thought that it would be around 75 degrees C, before damage would occur.

FYI: i have fan cooling the PWM, and watercooling on northbridge and CPU, and to be honest the water is redundant, i could easily get this clock on air.

would be nice to make use of it with some high temps to cool , and we are coming into winter here, so i would allways push a little further.

but no matter what i do here, i cant get past 3 gig stable, even that is a push, i run 2.8 gig most of the time.

off topic: Crysis, hell yeah, i have the benchmark tool, but use the console tool to gauge FPS in multiplayer, its just better for me to gauge performance. i get 35 fps average on my 9600gt @ 760 core/1011 mem and my Phenom @ 2.8 gig, dropping to maybe 20 fps when two or three nukes go off
I have Zalman Ramsinks on my PWMS..They get screaming Hot when i Prime with Volts above 1.61v.. this Mobo i intended to be my trial and error Mobo..Since the first 770's had tha massive Pwm problems i went with a Biostar ,,TA770 was one of the few at the time that wasnt failing with Oced 9850 when primed up to say 2.8ghz..So i decided to push it.

I'm under water too, with CPU/NB at 1.525v getting ~49C running BOINC.

Also just curious what the max 24/7 temps you run your chip at?
Im @ 54c with 3450 @ 1.56v for both CPU and NB...I have to wait till end of September to finish up this little study with Max Vids...This Mobo just cant handle the CPU .. I did manage to pull some interesting results though

When I had the 6400BE in I got my fsb/nb and memory up to 280 1/1 on this mobo max and 270 for 24/7 settings.

Now with this Phenom I have not been able to boot at 250, I never messed with those high voltages though and usually just left them at auto or around 1.175 not knowing exactly what they did or how much they could take since I didnt mess with them for the 6400 why would I have to mess with them for the phenom? right??.......but we are dealing with 4 cores instead of just 2 so your info helps to make more sense of it.

Also through reading this post I also noticed another mistake I was making, In the section of memory timings I just noticed that there are settings for each stick of memory. I didnt realize that until today when I went in it had the option called "both" When I set that there were many more settings than I had realized. I have been only setting one stick of memory timings and leaving the other on auto this may have been causing an additional problem for me also.

Although I have been doing excelent with my results from my eyes there is always room for improvement and this post has helped me learn a little more. thanks and excellent post
The whole X2 vs X4 thing is a give in.. This Mobo i can run 317+ with my X2 and Only 288Max with phenom.. I really believe these chips are designed for AM3/HT and are bandaided on any AM2/AM2+ even the new GX'x 790's the HT acts the Same with Bioses. I feel that the Bioses Should be made Exclusive for Phenom with a dual boot option if you need to throw in a x2 for trouble shooting.

Nb volts stabilizes the CPU better when it starts cranking .. Low CPU/Nbvolts is only good up to say 3.2/with 2400mhz or higher NB for me at least running stock vcore.. Just like X2's using default volts only let the CPU do so much..Im not insane so When im not deciding on using High HT i just settle for 3450/2660 with 1.56volts both CPU/Nb .

I also keep the (moboSB/nbvolts @ 1.31v--when set to 1.33v = droop) and HTvolts a little higher than stock @ 1.325 --when set to 1.35v = droop too. If you look @ my Bios screen post above.. Th CPU voltage first line is wher i would add extra volts if needed..I usually leave this on AUTO 24/7 with using Hexadecimal (00) = 1.56v for the CPU and NB on CPU ..Both get 1.56v

When it comes down to performance and Benching and Gaming and even when using more than 2gigs of Ram ,,Yes

..Remeber that i am using Water and @ Idle with 3450@1.56v im nice and cool @ 29c Idle and 54c Loaded After my loop is @room temp 26c.. High end Air is very simalar..

You seem to use an PSU with more than 18A for the 12V rail, because otherwise your PSU should power off due too that limit been exceeded.
May I ask what limit your PSU has for the 4pin 12V rail?
I can set my NB2400@1.31v up to 2680mhz my NB max@1.55v ...I can run that speed @ 2600ghzCpu/2600mhzNb ...Multi to 17x and 204ht 2660Nb or even HT and NB @268 ..I does almost any multi up to 17.5x then my HT only needs a few mhz to crank the NB anyway. Past 3.5/2580 requires 1.61vCPU and 1.55vNb .I have screens of 3.55ghz/ but the mobo will cook if i keep going. Prime would instantly start cooking Mobo at 3.55/NB+ speed with the volts needed pushes the PWMs too hard...

Now this is why im gonna get a better Mobo soon. Hm a 790GX/sb750 Biostar and im patently waiting for possiable DFI790FX/sb750..I want to order my goodies at the same time so i pushed backed my purchases to End of Sept. In case a real wicked Mobo comes out and prices should drop a few more bucks for another 9950(125watt to 140watt) so i can push that too and compare,, I know...

Hmm my +12volt is 52A budget ThermalTake 650.. Oh yeah it also cranks my sytem (11x120's 88cfm and 655 that i redrilled and then my 3870x2(stock Air to 918/200 while CPU@ 3450 eating up all my games)

Now @ 3450mhz and 3.55ghz My Supi 1M is still 22.5's-22.7's..Its so smooth i dont need more than 3450,, there is a noticable differance between 3.0 and 3.4,, Huge

P.s hope i got that covered.
