Bios nForce 2 Fine adjustment, Tuning, Options [Page 1]

For fast PC boot up the "boot up floppy seek" = floppy disk drive search is
prefered set on "disabled".
Gate A20 option generally on default value "fast"
HDD S.M.A.R.T. supervises your hard disk on funtion and temperature.
In disabled mode you save system resources.
Logo options concern to the black BIOS startup screen with informative ones.
To values. Full logo = complete screen filled
Small log = only lower area informatively filled.
Overclockers often disable the Screen LOGO show options.
In few cases this screen was responsible for PC start mistakes.

Here you also Find the entry " Serial ATA " for the support of modern SATA-Raid
disk drives.
If in your PC disk drives IDE are applied, you should this setting on disables value.

For overclockers we have a seperate BIOS topic area, which one view the
functions and options for over clocking is important. This is a seperate web page
break down. Here in the BIOS area we limit the guide on optimization.
CPU Interface: Optimal or agressive. Agressive heads for the CPU faster.
Recommendation: Agressive activate
Memory frequency: Recommendation ''Auto'' , "100%" and on MSI Mainboard 1:1
That takes cares your memory run synchronously 1 to 1 clocked to the CPU
Front Side Bus (FSB).
The memory frequency setting "SPD" puts the memory clock and the latency
values on memory programmed association positions by supplier.
On nForce2 I recommend generally synchronous clocking CPU to memory FSB.
Asynchronous clocking can lead to instability, particularly with higher clocking.
Note: higher RAM FSB than CPU FSB runs mostly. A RAM FSB under CPU FSB is a
problem factor on nForce2.
What you are able to do with the % memory clocking of choice setting, please find
on web page 2 of the nForce2 BIOS guide.
Memory timings: Optimal, Agressive, turbo
The attitude setting affects, the values RAM latency in the lines under it.
Subject of agressive or turbo settings is, lower latency times.
Suggestion: Try agressive and test with the programm "Memtest" stability.
Perhaps, increase memory voltage [vdimm] lightly.
With problems, choose the optimal setting.
The "expert" setting lets you decide all latency values by self in manual use.
FSB and AGP Speed Spectrum: Value on "disabled", Speed Spectrum options
cost performance.
AGP Aperture Size: Recommendation 50% of the real main memory of the
graphic card.
AGP 8x Support: choose 8x if the graphic card has AGP 8 support.
AGP Fast Write Capability: Disabled costs minimal graphic performance and is
more certainly, because the graphic card transmitt no direct straight orders to
the CPU as receiver.
Recommendation: disabled. Who would like to take the performance with, try
option enabled and with problems put back.
System Bios Cacheable: Recommendation on "disabled".
Modern operating systems and mainbaords is the paging of the biology in the
main memory not necessary.
The setting "enabled" cares occasionally for problems in the PC stability.
