BIOS Award 2/01/2005

The shipping Gigabyte BIOS for the K8NXP-9/K8NXP-SLI family provides a wide and useful range of adjustments for many features, with the notable exception of a very limited range of memory voltage adjustments compared to other boards in the SLI roundup. As is the Gigabyte custom in recent designs, Advanced Chipset Features (and Memory Timings) can only be seen when you hot press CTRL+F1 while in the BIOS. HyperTransport adjustments are also provided in the hidden Advanced Chipset Features menu.

There are no BIOS options for adjusting or controlling SLI. This is handled in the nForce4 platform drivers and the nVidia graphics drivers.

The Gigabyte K8NXP-SLI, like the sister K8NXP-9, was designed as a top-of-the-line nForce4 motherboard. As the flagship model, it sports all the top Gigabyte features.

The SLI version features start with the trademark DPS daughter card that you can see on the right of the board picture. This is used to increase power reserves and stability by increasing the board to 6-phase power. You can see the DSP slot to the left of the CPU, and the trademark Gigabyte dual BIOS chips to the right of CPU. This Gigabyte feature provides back-up BIOS in the event of a bad flash or unstable BIOS setting.

Gigabyte provides eight SATA ports. Four ports are 3Gb/s ports provided by the nForce4 chip, and the four additional are the 1.5Gb/s ports driven by the Silicon Image 3114. The 2nd group of ports is useful, but they would have been much more exciting if they had been 3Gb/s ports like those provided by nForce4. They do support Raid 5.

We are pleased that Gigabyte uses the nF4 on-chip Gigabit LAN by supporting it with a Vitesse (Cicada) Gigabit PHY. Gigabyte then goes one step further by including a second Gigabit LAN on the PCI Express Bus. This second LAN is also removed from the constraints of the slower PCI bus as it resides on the much faster PCIe bus.

Audio is AC '97 2.3, supported by the popular 8-channel Realtek ALC850. The K8NXP-SLI9 includes a wide range of audio I/O provided to make the most of the 850 chip. This includes 6 programmable audio mini-jacks and coax SPDIF in and out - all on the rear panel.

A pioneering feature for Gigabyte has been their support of high-speed 1394B Firewire on their boards. This continues with the K8NXP-SLI with 2 ports capable of 800MB/s or Firewire 800. This is double the speed of 1394A for those looking for fast Firewire access.

From a feature, board layout, and BIOS options point of view, the K8NXP-SLI can be considered the twin of the K8NXP-9. The only real change is the replacement of one PCI slot with a second PCIe video slot. All the good things about the features and layout of the K8NXP-9 are still here in the K8NXP-SLI.

    Wesley did you spend any time at all on this link, I consider this to be a serious issue

    When I set up my MSI board I cannot get surround sound out of the optical digital cable except for DVDs. I verified this on a few web sites. Not why there is conflicting information but mine is real world experience with current drivers (did not use packaged CDs)

    The onboard Creative Sound Blaster Live! 24-bit samples at 192 KHz instead of 96 KHz (like Realtek's ALC880/880D and 850) and features full support for Creative's EAX HD technology. Additionally, the soundcard has also passed Dolby certification for Dolby Digital and Dolby Digital EX and has an integrated Dolby interactive content encoder!

    #41 I've got a TT WS0049 PS, so I should be good with the -5v.

    #43 I've already cancled my DFI SLI DR board. MSI here I come ($238 cdn... so it's cheaper too) :D

    #42 - The on-board nF4 LAN requires a PHY (Physical Layer) gigabit LAN to function properly, but is specified as PCIe. All 4 SLI boards implement PCI Express Gigabit LAN with the PHY chips (Vitesse or Marvel). If you check all 4 manuals you will see Gigabit PCIe LAN specified by all 4 for the on-chip LAN.

    #40 - From the MSI manual Audio specifications:
    "Dolby Digital Encoder. 24-bit/96-192kHz audio quality. Up to 100db SNR. 7.1 channel H/W audio."

    Wesley,
    "all 4 SLI boards implement PCIe on Gigabit #1"

    I don't think the onboard LAN on the nForce4 chipset uses the PCI-E bus, are you sure about this?

    Here's the address for a MSI forum note concerning the problem with the Creative onboard sound and power supplies without a -5 volt connection.

    http://diamondclub.msi.com.tw/eng/forum/viewthread...

    And, if you take a look at the ATX12V Power Supply Design Guide, you can see that the lack of a -5 volt connection on many current power supplies should not have come as a surprise to MSI.

    WOW! This is looking good...
    Manual available here:

    After installing teh creative audio driver, you are able to use teh 2-,4-,6- or 8- channel and the SPDIF audio featre now..

    Page 5-11
    Decoder shows SPDIF Passthrough option!!!

    I am not familiar with the old Creative Live 24 hardware or menu settings, but is this new?

    BTW: If this is the case, I am canceling my DFI preorder (I've been waiting almost 1 month for this board to become available....)

    Good things may indeed come to those who wait! There is no better way to hook up to my Z5500's if the encode is supported!

    #28, #31, I'd really like to know as well...

    #32, I guess this is brought up, because of this statement in the roundup (on the first MSI Page)
    "The Audio also fully supports Dolby Digital encoding, which will matter a great deal to some users."


    Anand, is this some sort of typo, or can the onboard solution in facte ENCODE dolby digital audio. The ENCODE assumes that it can take .wav audio and encode it to dolby digital and place it on any (analog/SPDIF Coax/Toslink) output (ala IntelHD and SoundStorm)

    Let us know :D
