BIOS features/Nforce2

Its a long story but it comes down to a 100Mhz FSB jumper pin that Nvidia designed not being implemented by board makers. Only MSI included this in their design.

Not true ,the Asus has that jumper too ,I know I've got one

Spread spectrum btw is a feature to reduce EMI (radio emission output).It does this by slightly varying the clock speed continiously ,as you can imagine this doesn't help stability or performance.Disable it unless you are having interefernce problems with your TV or radio sat next to your PC

Gmac & any other Nforce2 owners, be aware:

There is a problem with Nforce2 boards that can render them inoperable when o/c. Apparently if you o/c too high the board shuts off and refuses to work!! Several Asus owners have already found this out.

Its a long story but it comes down to a 100Mhz FSB jumper pin that Nvidia designed not being implemented by board makers. Only MSI included this in their design.

If your board locks then the only workaround known is to install a Duron to make the board detect the 100Mhz CPU and then reset all settings in BIOS.
If you haven't had this then dont worry cos the makers are releasing a new BIOS soon to rectify this problem.

Spread spectrum - cant remember exactly what thats for but everywhere i've seen about it has them set to disabled
AGP aperture i have set to 128Mb, but it should be at least the size of the AGP memory.
AGP clock is the AGP FSB - default is 66Mhz, and you dont want to deviate too far from that or you'll encounter problems or possibly damage the AGP card.

You can o/c you GPU (graphics processing unit - aka core clock) & AGP memory FSB's. I dont know wat the implications are for on board graphics, but i guess they will affect your IGP, which i believe is in the Northbridge. Not sure if the AGP memory is also located there.
I'd be cautious with your o/c - you'll probably see glitches on screen before you damage anything, but if you do then you might need a new board

Nforce2 are generally good boards though - i got the Epox one, and aside from a few niggling things it is great.

OK, so i've been giving MSI a hard time for rushing out mobos to the consumer before they're"ready".But now i have gotten to "know" my K7N2G and all it's querks i decided to test this new chipset out.I have to say that stability when considerably overclocked is very impressive.I have o/c my 1.8xp to 2ghz/333fsb running in sync with crucial 333ddr timings 3-2-2,and managed a 3DMARK of 6,000 without a flicker,not bad for on-board vga.There are some questions though regarding the following BIOS enteries and exactly what it is they do:-
FSB Spread Spectrum.
AGP Spread Spectrum
AGP Aperture Size
AGP Clock Value
I am also a fan of 'coolbits' nvidia o/c facility and am wondering what it is i am actually overclocking when adjusting the core speed if my vga is on-board,does it affect the frequencies within the northbridge chip? Sounds dodgey.
Any tech. buffs? Many thanks.
