BIOS Intel 0420 (01/05/2006)

The Intel D975XBX is a member of the Extreme Series product family and, as such, is a fully featured flagship board targeted towards the Intel enthusiast. The board ships with an extensive accessory package that includes a 3.5" front panel bay for audio, IEEE1394, and USB 2.0 connections. Intel also includes several desktop utilities for monitoring and tuning your system.

This is the main BIOS screen and displays the generic options available on the board.

The advanced BIOS section allows you to view or change the majority of the system settings.

The advanced screen allows you to set individual parameters for voltage, multipliers, and chipset settings. You must first answer "yes" to the standard legal verbiage before being allowed to modify the limited range of settings. The Host Burn-In Mode Type option allows you to set a positive or negative value when determining whether to increase or decrease the front side bus. The Host Burn-In Mode Percentage option allows you to increase the front side bus up to 30% in 1% increments.

The board fully supports manual memory timing adjustments or allows for a Default setting that will set the memory to the SPD settings. The memory voltage settings have been increased to 2.2V.

Overall, the BIOS options are sparse on the Intel D975X compared to other enthusiast boards, with memory voltage to 2.2V, and a limited range of chipset, bus, and vCore voltage adjustments. However, the support for a 1333 FSB is interesting at this time. The BIOS will not recover by itself if you choose an incorrect setting. You will need to power down the system, switch the BIOS configuration jumper, power on the system, make the necessary changes in the BIOS, power down the system, switch the BIOS configuration jumper, and then power on the system. We cannot understand why Intel continues to require this interaction on their enthusiast board as it can become very frustrating while exploring the performance abilities of varied components.

    Im a self build Virgin - but I'm going in at the deep end. Intel's site makes their Dual Core stuff sound awsome!(a) Is it?(b)Should I look to spend my cash elsewhere when considering a motherboard/processor? Reply

    This board is fine for stock performance and if you get rev-0304 it works very well with Core 2 Duo. Reply

    Does this board support dolby digital live in the sigmatel audio chipset? I'm looking to replace my old SoundStorm setup.

    Also, does Intel High Definition = Dolby Digital Live support?

    Unlike most users of this motherboard that want to use the dual x8 PCIe slots for graphics, I want to use them for benchmarking a pair of x4 data acquisition boards we are developing. I want to test max rates to and from memory, as well as peer-to-peer transfers between the two boards (assuming the MCH allows this).

    So my question is: Do you think I can I put a x16 or x8 PCIe graphics card in the third x4 PCIe slot hanging off the south bridge? I don't care about graphics performance too much, I just want a dual monitor card that will work in that slot and leave the main two slots free.

    And ideas on this would be helpful. Thanks!

    Hi Neil,

    I had video working in this slot. I updated to the new bios release today and will test the performance in a couple of days.

    Thanks,
    Gary

    Neil,

    Performance is average but it works.

    The x16 interface supports full duplex transfers up to 8 GBytes/second in x16 operation and single-ended transfers are supported up to 4 GBytes/second in x8 operation.

    error! That's not how pcie works! pcie is always full duplex, and never single-ended!
