First time overclock

[csm]

I have a couple questions regarding voltages.

cpu: amd 965BE C3
Motherboard: M3A32-MVP Deluxe
Ram: 4gigs of OCZ 1066 DDR2
CPU Cooler: Corsair H50
os: Windows 7 Home 64bit

This is the first time I've ever overclocked and while I have read as much information as possible, I still don't understand a couple things.

CPU: 3811.6 GHZ
Core Voltage: 1.38
Bus Speed: 200.6 MHZ
HT Link: 2006.2 MHZ
Memory Volt and settings: 202, 5 5 5 18
Idle Temp: 38C
Prime95 Temp: 54C

The only settings I have changed in Bios to overclock are the cpu multiplier, the core voltage and the memory voltage. A lot of guides/posts I have read have talked about the CPU-NB multiplier. What is that exactly? And do I need to change it? Would it increase performance? Ran Prime95 for 6 hours without incident at the moment. But like I said, I'm really new to this stuff and I just want to make sure I'm doing everything correctly. And should I try to push my processor farther? Would I get any performance gains out of it for games? This is primarily a gaming computer.

Thanks for any responses.

CPU-NB multiplier is the control for the Northbridge/Integrated Memory Controller/L3 Cache. Technically, it's called the uncore. Raising it's speed will lower memory latency, and allow data to travel from main memory to CPU that much quicker. With your CPU at 3.8Ghz, I'd suggest at lease 2.4Ghz. To change it, there should be an option in your BIOS, not too different from changing the CPU multiplier.

3.8 GHz at that voltage, seems like you got a nice chip.

would I have to adjust any voltages?

Possibly. Some of the new C3 chips have hit 2.4Ghz on the Uncore with very little or no voltage tweaking. You'll just have to try it, and figure out where your chip can go. If you have a decent cooler, putting the NB-VID to1.35V will give you some playing room without adding too much more heat and power usage.
