Ultimately yielding Lwer Load Temps.......
LOL sorry I'm so lost, I never knew or heard of voltage counterbalancing, or that adding voltage to the NB can result in lower stable CPU vcores. As for "HTRClk", are you refering to the HT Link frequency? If so I have it set at 2002MHz (286 fsb x 7 multi).

So what voltage should I set my NB to exactly?

and after that is complete, all I need to do is keep undervolting my CPU until it's stable? Thanks

he is referring to the FSB/HTT/HTRclock lol it has so many names.

i keep hearing that the thuban temp sensors are inaccuarate. this could explain how Regamaster had lower idle temps than the ambient temp. someone said you have to add 10c to whatever its reading. i put this to the test by shutting off all my fans and running prime. it took about an hour to get it to 59c. so if that add 10c were true, this cpu kept running at 69c. i need to do some research.

I would guess thats for idle temps...load temps seem to work out about 5 degrees lower i think...

No need for apologies but apology accepted just the same!

Front Side Bus (FSB) was the old tech used by AMD back before 2003 (Intel used it up until the Nehalem). This was the connection between the CPU and the rest of the components. Hypertransport is now the connection between the CPU core within the Processor and the rest fo the Components. 286mhz is the HT Reference Clock (Or Hypertransport Reference Clock) or HTRC. the HTRC is merely that. A refernce clock to base frequency of the CPU, Core interconnects and Ram.

Intels old Fsb was MAX OC's to about 2ghz whcih only provided about 16gb/s max bandwidth for the Entire System.

AMD's HyperTransport Link being a Larger Path and in Duplex (Double or up and down in this case) can provide upto 64gb/s Max bandwidth for the Entire System. That's at 4000 2ghz up and 2Ghz Down at 16bits per direction.

THIS reason alone is why it is not neccesary to OC the Hypertransport Link on AMD systems. Unless one is doing some Major, I mean Major 3D rendering of some sort, there is really no need to go beyond 1.8ghz to 2ghz HT Link frequency....

Hope this helps with your understanding.

i've noticed slightly better 3dmark scores with a higher ht link. by slightly i mean no more than 50 points.

2hrs stable so far with 3200nb. still trying to figure out whats going on with the temps (accuracy and such). i decided that since the base of the heatsink and pipes are not very warm, the cpu isn't very warm. thats my scientific analysis.

thats kick ass bro
If i ever get one.. hopefully I could reach that high on NB.. I haven't ran still 3000NB on my 965 on this mobo... I'll need to flash the bios to play with it

i couldn't get anything over 2800 stable on my 965. its strange not having an unlocked mutiplier after having one for almost a year. gotta think about what the other settings are at all the time now. i guess i do have a sempron 140 that doesn't have an unlocked multi. thats a fun chip. it cost $30 and i dont care if it burns up. i've gotten it to 4ghz but kinda hit a wall there. no time for that now that i have this thuban!
