CPU interface option? NF7-S

[Gameaholic]

what exactly does the CPU interface option do in the NF-7s bios?

Disabled = use most stable paramaters
Enabled= use overclocked paramaters

but what does it change?

sorry for noob question

You won't find many quick answers at this hour in the US. But my input is better than none. I do not own that motherboard. But by "CPU interface" it sounds like it's interface with your RAM. Overclocked parameters must mean that the ram timings are set lower or the clock speed is increased. To overclock the actual cpu I have never heard of an enable/disable thing, so that is why I assume it is the ram it is changing. To over clock the cpu you manually adjust the fsb and the multiplier. Most stable parameters would be normal functioning that your hardware was built for. Until someone with an NF-7s can come along, you should probably keep it set to normal.

Kind of break down what Auzner is saying.

CPU Interface, in lamen terms, does a small OC on the CPU and Memory, while still retaining the settings set in the BIOS. This is why people disable it when trying for high and stable OC's.

Kind of like adding a small 50HP NOS setup to a factory engine .

Referred to as CPC on/off on some nForce2 boards, and command rate on A64.

Enabled will set the memory to 1T, and disabled it will be set to 2T.

This is not true. Pretty much all i know is that use cpu interface enabled for max performance. But it is not CPC. That is a totally different setting and can be enabled or disabled by using different bioses since abit is too lazy to release a bios which allows us to edit this feature.

On my old EPoX nForce2 board, CPU Interface set to Agressive = 1T and Optimal would = 2T. Maybe ABIT's CPU Interface option changes something different, which is why a modded BIOS is neccessary to change command rate?

I also think CPU Interface and CPC are different. A lot of people talk about CPC not many really know what it is. I know because I kept asking, and all I was getting is Command Per Clock, that is it. Here is an article that explains it well:

Thanks for this link man

You are welcome

Well it always offers better performance with CPC on. However, usually you can't overclock as high with CPC on. So what you have to consider is, does the performance gain from overclocking to a certain speed, is greater than having CPC on at some lower speed. I think same is true about RAM timings. You have to try both, run some benchmarks (3D2001, PCMark, Super Pi, etc) use your PC for a while and then make a decision.

But I am guessing that in your case it can be said that you will benefit more from CPC on, since you have PC2700 RAM, and you can't expect to overclock it much higher than 200Mhz, even if you get there.
