    Default The motherboard that breaks the limitation of memory:DFI LANParty NF680I LT SLI-T2R

    Recently, the hottest chipset of NVIDIA must be NForce 6 series (Intel
    In fact, 680i is the highest model of them all, which has SLI x16 + x16
    /EPP/QuickSync technology….etc. The publicity of NV 6 series is “on the rise”
    these days, even though the Intel chipsets are so strong in the market.

    Not long ago, I released a review of 680i’s reference board.
    That is also the board of many others manufacturer too (same board,
    just print their logos on) No matter the spec. or design of it is also real
    excellent; particularly the
    DDRII OC parts is defeats all Intel chipsets. But it was pity that the
    reference board of 680i only can reached 470MHz when installed with my X
    6800 CPU. Besides, I tried 965 mobo equipped with the same CPU, it ran
    around 500MHz… later on, some of the mobo manufacturers tried to design
    their own 680i. but seems non of them could do better than the NV reference

    Now, what I’m going to test is the overclock-oriented motherboard, DFI.
    The LANParty UT NF680i LT SLI-T2R is the highest-end of DFI’s LP product.
    It adopts 680i LT chipset; it is exactly the same spec to 680i. Maybe
    the “production quality” is a bit different to 680i.

    First of all, we check the package design first; it’s really “fashion-look”
    this time.

    The inside package contain 3 different parts.
    The 1st part: NB Heat sink.

    The installation guide of NB heat sink and the paste.

    Imprint Fins of NB heat sink with a LP logo.
    It is optional to install a 6 x 6 cm FAN,
    a great help to a high performance NV chipset.

    “Copper bottom” design. I heard that this NB heat sink will be sell

    The 2nd part, Accessory

    Includes User menu, driver CD, SLI bridge, IO shield, connect cables,
    Karajan audio module and RAID driver disk.

    The 3rd part: the board itself


    Lower left of the board: 3 x PCIe x16, 1x PCIe x4, 3 x PCI slots.

    The lower right parts:
    Power/ Reset button & Debug LED light.
    Pure copper South bridge
    6 ports of SATAII, which supports RAID 0, 1, 0+1, 5 functions
    Built-in Silicon Image SiI3132 chip.
    2 stackable SATAII ports with RAID function too.

    Upper left of the board
    IDE 24-pin power and 4 dimm DDRII slots

    The upper left parts:
    Unique 6-phase digital PWM design, except the better power supply stability,
    it also provide a bigger space for a “huge” CPU cooler.

    IO output
    6 x USB2.0 (total up to 10 ports), Dual gigabit LAN, 1394 ports
    (audio module not installed)


    There is a cushion pad between the heat sink and the surface of the chip.
    Just follow the instruction, the chip won’t be damage…

    The system details:
    CPU:INTEL Core 2 Duo E6420
    DRAM: CORSAIR TWIN2X2048-10000C5DF
    HD: WD1600AAJS
    POWER: Thermaltake Toughpower 850W
    Cooler: Thermaltake V1

    I recommended that install a additional fan with the NB, especially when OC
    over 400MHz…(BTW, V1 is really helpful, the air flow can help NB too, it’s

    The drivers installation interface:

    CPU: 266X8=>2133Mhz 1.3V
    DRAM: DDRII 800 CL3 3-3-9 1T 2.19V

    SP2004 steady…

    DDRII 800 CL3 3-3-9 1T is a option that 680i reference board can’t be
    I knew the revised version BIOS released, the reference board can works
    normally at last. But the voltage is higher than DFI680i LT a little bit.

    CPU: 266X8=>2133Mhz 1.3V
    DRAM: DDRII 1066 CL4 4-3-9 2T 1.98V

    SP2004 steady…

    I tried to show the performance between 680i and 680i LT when equipped
    with X6800ES CPU… (It ran steady at FSB470MHz)
    CPU: 450X8=>3600Mhz 1.4V

    DRAM: DDRII 1310 CL4 4-4-4 2T 2.67V

    Super PI 1M

    DFI 680i LT NB after increasing a little voltage, 500MHz FSB is easy to reach.
    Further, the highest voltage is 3.04V; it’s a wider range of voltage settings
    than 680i reference board. For my personal experience, this is the first time I
    reached 1300(CL4) with 2G DDRII memory. Quite cool…

    DFI did the best to make LT better than the hottest NV 680i reference board
    (by their R&D design). Moreover, the FSB and DDRII performance are
    obviously better than the reference board. It improves the FSB’s limitation
    between different CPU of Intel.
    Further, it also pushes the memory performance to a highest place under all
    Intel platform.

    Most of Mobo manufacturers sell the 680i reference board awhile ago and
    some of them have their own design too… DFI was late in launch their 680i
    LT as usual, but, the refined package design, thoughtfulness HW & BIOS
    design and OC performance are still the reason why enthusiasts like it.
    I’ll post a detail review about BIOS and some extreme OC test a bit later.

    The up-coming reviews:
    ATI RADEON HD2900XT 512MB CrossFire
    The ultra-high VGA product line.

    Thermaltake Toughpower 850W
    High C/P ratio and high power output Active PFC PSU

    Updated Seagate 7200.7 160GB HD, for increase the performance,
    I brought the WD 1600AAJS 160GB 8Mb cache memory. (a latest version)

    DDRII 1310 CL4 4-4-4 2T 2.67V

    Great mobo and ram.

    Nice review.

    and...cooler look good.

    “Booting screen”

    BIOS options
    Main page

    The voltage option pages
    4 different voltage statuses below are worthy to trust.
    If you want to OC with most of Core2Duo CPU, first thing is to increase NB’s
    voltage. Besides, I suggest that you push the VTT up to 1.4V or more when
    you use QX or E6X20 series.

    CPU GTL 1 REF Volt/CPU GTL 0/2/3 REF Volt/NB REF Volt=>around170/90/95

    CPU Highest Voltage 1.60000V

    DDRII Highest Voltage 3.04V

    NB Highest Voltage 1.74V

    CPU clock and DDRII clock option
    This is almost the same way to NV’s 680i CRB (reference board)

    CPU Feature

    The parameter options page of DDRII

    PC Health status
    About PSU: +5V/ +12V the display of them seems a bit lower than the real
    Besides, the display CPU temperature seems higher than the actual one.
    But all them will be fixed in the latest BIOS version.

    Test system detail
    CPU:INTEL Core 2 Duo E6420
    DRAM:CORSAIR Dominator TWIN2X2048-8888C4DF
    POWER:Thermaltake Toughpower 850W
    Cooler:Thermaltake V1

    I hope it can have a good performance when equipped
    with Corsair Dominator TWIN2X2048-8888C4DF


    CPU 450 MHz/DDRII 1200 CL4 3-3-3 2T 2.40V

    Dual SP2004

    The performance of X6800(ES)
    CPU 400Mhz/DDRII 1200 CL4 3-3-9 2T 2.36V
    Dual SP2004 runs stably

    CPU500Mhz single Super PI 32M

    DDRII Memory is real good
    CPU 450 MHz/DDRII 1310 CL4 4-3-3 2T
    Sandra/EVEREST broad bandwidth of memory…

    It’s a bit pity about the divisor…
    no way to run the broad bandwidth test under 500/1310 ratio.

    The merits
    1)an organized and unique graph (includes package design, boot-up picture,
    and the image of driver CD)

    2)Also a unique design for the NB cooler, a extra fan will make it better too.

    3)LANParty BIOS options: the range of frequency/ voltage is real “wide” for
    users to tweak.

    4)If the processor quality is good enough. It can easy to reach FSB500 or
    above. DFI’s is better than NV’s CRB a bit.

    5)NVIDIA’s 680/650 are the only models of Intel platform which can supports
    SLI function.

    The defects
    1)a little bit late to release in market; It can have a better competitive power

    2)NVIDIA chipset’s problem…high temperature from chipset

    3)Lower voltage on detection, higher temperature when measure,
    that needs to improve

    I believe it wasn’t a coincident that EVGA’s CMB has good sales result from
    the market. Except the SLI technology, NV is a step-ahead than Intel on DDR
    memory overclocking.

    Actually, DFI LANParty UT NF680i LT hasn’t adopts 680i but 680i LT.
    But design ability is overcome most of problems of LT version, it did reach a
    higher record of FSB than 680i. In addition, although LT version isn’t supports
    DDRII1200 as 680i, but in fact, it shows a better performance than 680i CRB.
    These are the remarkable points of this LP UT NF680i LT.

    680i and 680i LT basically is the same chipset, but separate by its process
    Ha, I suggest DFI to have a 680i Ultra, particularly its LT version has a better
    performance than 680i CRB.

    Obviously, LANParty series motherboard is getting improved step by step in
    this year.
    If they can launch their product a little earlier, set the price a little
    reasonable and the detection of the system can be more accurate. I think
    DFI’s product will “walk tall” in front of all 1st tier brand.
