    Bios Tweaking

    on a NF7-S v2

    • CPU FSB/DRAM ratio (what should i set, it's at 3/3 at the mo)
      CPU Interface (Turned off at the mo)


    • Enhance PCI Performance on or off ? (off at the mo)
      CPU Disconnect Function on or off (off at the mo)


    Can any one point out what these features do and would it be best if they where on/off ?

    Andrew.

    CPU FSB/DRAM ratio (what should i set, it's at 3/3 at the mo)
    You want to run in a 1:1 ratio as yours is.
    Personally I run 6:6 as I'm over 200fsb but if yours is happy at 3:3 great.
    The figures supposedly relate to multiples of the PCI bus clock (e.g. 6x33.333 = 200) but I don't think it's critical.

    CPU Interface (Turned off at the mo)
    You want this enabled if you can.
    It affects the CPU's ability to access memory & makes a significant difference in performance.


    Enhance PCI Performance on or off ? (off at the mo)

    Not sure - as i don't use any PCI card I have disabled

    CPU Disconnect Function on or off (off at the mo)
    Allows for a lower cpu temp when idle - I have enabled but some people says it affects your overclock.

    Are you sure? There'll be devices onboard the motherboard that use the PCI bus...

    I have no idea what it does though as I don't have a mobo with that BIOS option.
    PHP Code:
    $s = new signature();
    $s->sarcasm()->intellect()->font('Courier New')->display();

    The general recommendation (& default) is off for better stability when overclocking.
    Suggested that if you use the onboard RAID to try though.

    CPU Disconnection Function should be disabled, it's been directly linked to sound issues with SoundStorm, crackling, cutting out etc... a statement was made on the nForcersHQ forums by an NV respresentative directing nForce2 owners not to use the feature.

    Oh well, works fine for me with no crackling etc. but ymmv.

    P.S. LayZeh, do you have a link to that thread? nForcers search engine isn't the best I've found

    Also, disable any ports you don't use. I disable the printer port and the COM ports, i just do it for good measure, perhaps it's less for the POST to test?

    Is that only analogue SS? I use the digital coax output (couple of bits of wires jammed into a RCA plug - Why couldnt they put a coax rather than the optical connector???) only when @home but when at LANs on headphones have noticed sound artifacts in certain situations. This was on my asus A7N8X-Dlx v1.06 not my new NF7-S v2 (which I havent even used the analogue ports on!)
