CPU-NB/NB question.

post #1 of 5
Thread Starter 
So what exactly is NB setting in the bios? I've got a setting that says NB, in fact here is what I have under that setting:

Code:
CPU Frequency Multipler  15x (3000)
CPU Frequency Voltage    1.40
NB Frequency multiplier  x8 (2000)
NB Frequency Voltage     1.20
Now the thing is, normally the NBv is 1.10, but if I want my ram to run at 1600MHz I have to up it to 1.2 or it won't do squat. Well, it will post but then it BSODs. So my question is, in this case would that be CPU-NB or? I'm exactly lost as to what this setting is, cause everyone says NB is not the CPU-NB, but I thought the CPU-NB was the only thing that dealt with the RAM.

Now that the memory controller is integrated in the cpu, the cpu-nb deals with memory related jobs. It would be even better if you post a pic of that bios screen here.

I'm compiling a linux desktop atm and don't want to reboot. lol But that's a pic of the area, below that is (I believe) settings that relate to HTT or something, no.... It's two settings, HT is one and the other I don't remember.

Victory is mine! HT bus and HT Width, but that first one has the expanded settings for the voltages and stuff. That's all I have to work with. =P

Yep, it seems that way. Since I cant find any trace of cpu-nb whatsoever, I think 'nb' stands for cpunb here.
Only one way to check it. First set it to 2200/2400mhz by adjusting the multi (nb multi) then use cpuz memory tab to see what cpu-nb you are running. If its 2200/2400mhz, then the case is settled.
With some boards you have to adjust the cpu-nb voltage a notch or two to get stable ddr3 speed (if you are running over 1333mhz), so there is nothing to worry about. your cpu-nb can easily handle upto 1.3v (at the least).
