Currently, both are set to AUTO.

CPU/NB is the memory controller which used to be in the NB but is on the CPU chip these days, but it has its own power and clocks.
NB is the "real" NB.
So if you want to tune memory CPU/NB is what you want to tweak.

Alright.
My BIOS options are different than what I had recalled.
My only available options are as follows:
VDDNB overvoltage = auto
HT overvoltage = auto
CPU/NB frequency = 10x
Loadline Calibration = auto
Chipset overvoltage = auto
SB overvoltage = auto

No problem
The CPU/NB refers to the IMC,or on-die memory contoller.It is physically inside the CPU.
The NB refers to the motherboard chipset,in your case a 780g.

In order to run higher NB frequency,you increase the CPU/NB voltage in proportion to the speeds.
You may also need to bump up the regular NB voltage a little also when using higher RAM speeds

Edit-just caught your edit
the VDDNB is the CPU/NB voltage
chipset voltage is the NB chipset voltage

Hmmm. It seems like it might be a little hard to increase the NB frequency if the max NB multiplier is 10x,
and my CPU is a locked CPU. Unless there is something I'm missing, I guess I can't get it any higher.
When I try increasing my FSB multiplier any more, it refuses to boot windows. I don't know if this is from a lack of voltage,
but I just know that it won't boot windows. My temps are all fine for the record. Currently, idle at 30C and while gaming it gets around 40C.
I never play on max load, but it typically gets around 50-55C in prime95 tests.

It seems like temperatures are up just slightly after increasing NB voltages...
Should I keep them raised anyhow? Or is there some way to increase the FSB more without frying anything?
Also, another thread online mentioned that NB frequency and HT speed are not important when compared with FSB...
If I lowered the frequencies on them, would I be able to jack up the FSB ?

You lower the NB and HTT speed,also the RAM,then raise the FSB.Then you adjust the NB/HTT/RAM to optimal speeds.Since you don't have an unlocked multipler you have to raise the ref clock to reach higher speeds,i.e.
http://valid.canardpc.com/show_oc.php?id=2204588

When you raise the ref. clock it raises everything,which is why I said you may need to raise voltages across the board.

Okay.
After hours of work, I seem to have everything stable again.
Got a minor FSB boost, but mostly my settings are the same as before.
It doesn't get as hot as before, which I don't understand, and appears to be working fine now.
RAM speeds are slightly higher than before, with the same timings.
I did have to bump voltages all around though; if you want to copy my setup, just send me a PM and I'll get you
the exact values. Otherwise, I think I'm going to stop screwing with it and keep it here...

At least until I try to overclock my video card. XD
