    I've been doing some digging again :D
    Since the BOG is trying to be "Definitive" I think trivial settings like these two and some of my previous ones should be included as well. It's just to make the BOG complete and some n00b might even get these confused. ;)

    AGP 3.0 Calibration Cycle in BIOS

    Adrian,

    First off, great site. Very helpful and easy to understand.

    I have been trying to understand the function of the AGP3.0 Calibration Cycle option on my motherboard (ASUS A8V), whether or not to enable it?

    I have a Ati 9800 Pro GPU and am sure it is AGP3.0 compatible.

    Please could you tell me what this function is under BIOS and whether it should be enable or disabled in the BIOS?

    Many thanks

    JuJu Man

    I Apologize....

    Oops! I posted in the wrong section....I clicked "New Thread" again, forgetting that it did this, not a new "Reply" as I should've done.

    I tried deleting the post to repost under the proper area, but I noticed I cannot do that. I wouldn't mind if a moderator did it for me..... (do the same to the other thread I made regarding a ABIT NF7-S2G mobo).

    And in case anyone reading this doesn't understand what proper area I mean, it's the sticky note in this thread.

    Cool....Now what do these mean....

    Thankx for whoever moved my posts to the proper thread :thumb:

    Now here are the things I do not know what they mean. I would like to know which option is suggested for best performance, and which option balances performance with stability. Thank you!!! :D

    Here they are:

    -----ABIT NF7-S2G options----------
    CPU Interface
    LDT Voltage
    Base I/O Address
    I/O Length
    IDE Prefetch Mode
    PCI Latency Timer
    PIRQ Assignments

    -----BFG nForce4 Options---------
    HT Frequency
    HT Width (Is this for lanes open? HT=HyperTransport ??)
    Err94 Enh
    USB Memory Type
    Resent Configuration Data
    FDD IRQ Can Be Free
    Maximum Payload Size
    Bottom of 32-bit[31:24] IO
    Read Preamble value
    Async Latency Value
    S/W Memory Hole Remapping
    H/W Memory Hole Remapping
    MTRR Mapping Mode
    CPU Spread Spectrum (I believe this is supposed to reduce EMI but what does center spread mean?)
    SATA Spread Spectrum (I believe this is supposed to reduce EMI but what does down spread mean?)
    PCIE Spread Specturm (I believe this is supposed to reduce EMI but what does down spread mean?)
    PCIE Clock (When do I ever change this?)
    Hammer Fid Control (What does this even mean?)

    - BIOS Setting: Top Performance
    - Options: Enabled, Disabled
    - Motherboard: GA-7ZXE
    - Chipset: VIA KT133A (I think)

    I'm not sure about this, but my previous mobo (A-Bit KT7) had a similar setting, which controlled the DRAM timings. CAS latency, RAS-CAS, or one of those. However, on this board, I find no change in the DRAM timings, whether this option is disabled or not. I don't think that SPD is overriding it, because the BIOS doesn't mention SPD at all.
    Anyway, since I'm running FSB100 (Duron800) and my DIMMs are 133, I leave the setting enabled.

    Cheers!

    - BIOS Setting: AGP Comp. Driving
    - Options: Auto, Manual
    - Sub-options (Manual): Hex values from 0x00 to 0xFF (defaults to 0xDB)
    - Motherboard: GA-7ZXE
    - Chipset: VIA KT133A (I think)

    No idea what this is, and haven't messed with it.
