Bios tweak questions

[Crash893]

okay im trying to get my bios stragined out


ill tell you what settings im having trouble with and you tell me if i should enable them or not

S.m.a.r.t for HDD ( enable or disable ) what does it do ( yes my hdd supports it)

floppy swap

fdd seek

dram timing config (its on normal right now but it also has fast and ultra ) is sdram133 i belive ( 256mb)

okay here is my crown question

Clock Gen Spread spectrum ( currently disabled should this be enabled)

when its detecting all the master slave drives on my system should i put that on auto or put in the actuall info?

those are my big questions im sure ill find more later

you wnat perhaps to set them all knowing what youre doing: best bios guide ever, imo (http://www.rojakpot.com/Speed_Demonz/BIOS_Guide/BIOS_Guide_Index.htm).
about the disks i prefer to detect them into the bios then to use the detected settings despite letting it to detect tehm during post, but this is only a speed matter.

Spread Spectrum

Options : Enabled, Disabled, 0.25%, 0.5%, Smart Clock

When the motherboard's clock generator pulses, the extreme values (spikes) of the pulses creates EMI (Electromagnetic Interference). The Spead Spectrum function reduces the EMI generated by modulating the pulses so that the spikes of the pulses are reduced to flatter curves. It does so by varying the frequency so that it doesn't use any particular frequency for more than a moment. This reduces interference problems with other electronics in the area.

However, while enabling Spread Spectrum decreases EMI, system stability and performance may be slightly compromised. This may be especially true with timing-critical devices like clock-sensitive SCSI devices.

Some BIOSes offer a Smart Clock option. Instead of modulating the frequency of the pulses over time, Smart Clock turns off the AGP, PCI and SDRAM clock signals when not in use. Thus, EMI can be reduced without compromising system stability. As a bonus, using Smart Clock can also help reduce power consumption.

If you do not have any EMI problem, leave the setting at Disabled for optimal system stability and performance. But if you are plagued by EMI, use the Smart Clock setting if possible and settle for Enabled or one of the two other values if Smart Clock is not available. The percentage values denote the amount of jitter (variation) that the BIOS performs on the clock frequency. So, a lower value (0.25%) is comparatively better for system stability while a higher value (0.5%) is better for EMI reduction.

Remember to disable Spread Spectrum if you are overclocking because even a 0.25% jitter can introduce a temporary boost in clockspeed of 25MHz (with a 1GHz CPU) which may just cause your overclocked processor to lock up. Or at least use the Smart Clock setting as that doesn't involve any modulation of the frequency.

Floppy seek= checks for available floppy drive during post. causes small delay and floppy led to light up briefly.

Floppy swap= switches designation of FDD A: and FDD B: if you have two floppy drives. Makes it easier to setup system, since if you hook up the two floppies backwards, you can just enable this setting instead of changing the ide cable.

if i wana hypertweak i have the tools to get my mobo as low as -40 deg cels how can i set my fsb only for cpu more then 166 ? i wana reach 5.5*270 :O

:D hope im in right place to ask this ! :D

I suppose you've got liquid N2 (or some other gas) cooling? I doubt you can get to 270 FSB, because the CPU is not what is going to hold you back. HDD, ram, AGP, PCI... those things will crap out on you if you go too high. A program: CPUFSB will help you set your FSB higher than your BIOS will allow. I think that's what you're after. www.podien.de has it. I think that address is right anyway. I haven't used it though so I can't offer any advice.
