    Default windwithme's LGA 1156 review part4-GIGABYTE P55-UD3P Parity Version OC Guide

    Itís been almost 2 month since Intel launched LGA1156 socket on 8th Sep
    The new platform product line and market position are clearer
    As my previous review, LGA1156 is still focus in between high end and middle end

    CPU has 3 models so far. The highest is i7-870 and middle is i7-860
    They both support HT which make Quad core CPU can simulate 8 cores
    i5-750 doesnít support HT and itís the most entry model now. The price is around 200USD

    MB Chipset is P55 and all MB makers also launched the products at the same time
    Currently, the P55 MB price is between 160~280 USD
    If you want to buy LGA 1156 platform, i5-750 plus 160USD P55 MB is the best C/P
    Certainly, if you need HT and also affordable, you also can consider i7-860
    Merely, i7-860 price is very close to LGA1366 platform

    The MB this time is GIGABYTE GA-P55-UD3P, price is 5200NTD
    This is entry price level for P55 MB so far
    First of all, itís the package. UD3P is not GIGABYTE high end series, so the box is not so big

    Product Manual、Smart6/Smart TPM Guide、Driver CD and IO Shield.
    SATA cables are 2 standard and 2 vertical head

    GIGABYTE P55-UD3P Body

    Lower Left Corner
    2 X PCI-E support CrossFire and SLI technology and the bandwidth is X8+X8
    1 X PCI-E X1
    4 X PCI
    Realtek 8111D LAN Chip
    Realtek ALC888 supports 7.1 channel and High Definition Audio

    Lower Right Corner
    6 X Blue SATAII supports RAID 0, RAID 1, RAID 5 and RAID 10
    2 X White SATAII supports RAID 0, RAID 1 and JBOD
    Dual BIOS, dual protection

    Upper Right Corner
    4 X DIMM DDR3 support 800/1066/1333/1600. The maximum DDR3 capacity is 16GB
    DD3 2200 is after overclocking spec. DDR3 has extra 2 phase PWM and 24-PIN head near by

    Upper Left Corner
    LGA 1156 CPU Socket
    UD3P CPU PWM is 8 phase and VTT is 2 phase

    10 X USB 2.0
    1 X RJ-45 LAN
    2 X eSATA/USB 2.0 Shared
    1 X S/PDIF Fiber /Coaxial output

    Close look to the components surround by CPU

    P55 Heatsink

    Audio、LAN Chip

    P55-UD3P Boot Screen

    M.I.T. Menu

    CPU.DDR3 Clock current status

    Adjust CPU clock ratio, QPI clock ratio and BCLK

    CPU Core Feature
    Turbo Boost Tec is auto OC feature in Intel Core i7/i5

    DDR3 Setup

    DDR3 parameters page
    B2B CAS Delay is the P55 exclusive item for DRAM performance
    The range is 1~32 and Auto is around 1~3
    The higher number means looser. Sometimes, you even see 1xxx MB/s which is lower bandwidth than DDR.
    However, itís also the key factor for pulling DDR3 clock

    Voltage page
    Load-Line Calibration Disable will raise CPU voltage as full speed/Enable will lower CPU voltage as full speed
    CPU Vcore 0.50000~1.90000V
    QPI/Vtt Voltage 1.050~1.990V
    PCH Core 0.950~2.000V
    CPU PLL 1.600~2.540V
    DRAM Voltage 1.300~2.600V

    PC Health Status

    All above are BIOS screen and also my OC setting for P55-UD3P
    XPU/DDR3 is 200/200 ratio.
    The OC setup may be different as depending on your components combination
    Even the same model and period Core i5-750, the OC ability are vary.
    Users need to find your best voltage setup by your own.

    CPU: Intel Core i5-750
    POWER: Antec TruePower New TP-750
    Cooler: Mega Shadow(Deluxe Edition)

    CPU 200 X 20=> 4000Mhz 1.35000V
    DDR3 2000 CL8 8-8-24 1T 1.500V

    Hyper 4 X PI 32M=> 9m 57.216s
    CPUMARK 99=> 621

    Nuclearus Multi Core => 7618/11364/33466
    Fritz Chess Benchmark => 24.76/11886

    CrystalMark 2004R3 => 313013

    1 CPU=> 5707
    x CPU=> 20405

    PCMark Vantage => 14916

    3DMark Vantage => 13038

    P55-UD3P can reach 200/2000 easily. Of course, CPU and DDR3 quality is also very important
    UD3P doesnít lower the OC ability as the price is cheaper.
    The OC range is very wide

    DDR3 OC ability
    Combine with the professional extreme memory maker CORSAIR latest product which supports P55 dual channel
    Black and Red collocate makes GT be more attractive

    Clock is DDR3 2000, parameter is CL8 8-8-24 and voltage is 1.65V

    DDR3 2000 CL8 8-8-24 1T, BIOS set as 1.500V
    SP2004 2 X Blend mode, 3.91GB full load stabled

    Sandra Memory Bandwidth - 24479MB/s
    EVEREST Memory Read - 18556MB/s

    DDR3 2160 CL8 8-8-24 1T,BIOS set as 1.600V
    SP2004 2 X Blend mode, 3.90GB full load stabled

    Sandra Memory Bandwidth - 25230MB/s
    EVEREST Memory Read - 19354MB/s

    DRAM doesnít need 1.8-2.1V as LGA775
    As Core i5/i7 bulit-in Memory Controller, the new DDR3 platform only needs 1.65V
    DDR3 2000 CL8 needs only 1.50V and DDR3 2160 CL8 also needs only 1.60V
    Above DRAM test, DDR3 quality is key factor, but also need good DDR3 OC MB to bring it out

    Pull up both CPU/DRAM
    CPU 216 X 19 => 4104Mhz
    DDR3 2160 CL8 8-8-24 1T

    Hyper 4 X PI 32M=> 9m 45.063s
    CPUMARK 99=> 638

    Nuclearus Multi Core => 7816/11660/34409
    Fritz Chess Benchmark => 25.42/12200

    CrystalMark 2004R3 => 319963

    1 CPU=> 5851
    x CPU=> 21272

    PCMark Vantage => 16033

    3DMark Vantage => 13119

    Compare to 200/2000 test, CPU only raise from 4G to 4.1G, so the CPU performance is not big jump
    However, as DDR3 2160 and also raise CPU clock and frequency, the overall performance still enhance quite much
    CPU clock can pull to 219Mhz, but itís not very stable. So I donít put in this report

    1.GIGABYTE parity P55 product still have good package and components quality
    2.2oz PCB, 100% Japanese made solid capacitors, and plenty of software
    3.P55 supports both ATI CrossFireX and Nvidia SLI
    4.Rich BIOS items, wide voltage range and great OC ability in CPU/DDR3
    5.Built-in 8 SATAII, 10 USB and 2 USB/eSATA combo ports

    1.SATAII position will interfere with long VGA card as GTX260
    (Even though GIGABYTE has 2 vertical SATA cables for compensation)
    2.Just launched platform has less CPU for choice. Currently, there are only 3 CPU

    Performance ★★★★★★★★★☆
    Components ★★★★★★★★☆☆
    Specification ★★★★★★★☆☆☆
    Outlook ★★★★★★★★☆☆
    C/P Value ★★★★★★★★★☆

    GIGABYTE has launched 4 P55 models in the market which are UD3P/UD4P/DU5/UD6
    The price is between 5200NTD to 9000NTD that equal to 160~278USD
    UD3P is the current lowest price model, however, the OC ability is not far away from the others
    During the performance test, UD3P performs in pretty high standard in OC

    P55-UD2 is GIGABYTE Micro-ATX P55 product but still donít see any in the market yet
    For this kind of mid-high segment, Micro-ATX is always launched slower
    I do hope see this kind of product more. The full product line is also a good weapon to compete with the other brands

    Core i5-750 plus P55-UD3P is the cheapest LGA 1156 combo so far
    For LGA775 users, upgrading to Q8400 and Q9550 is the cheaper solution.
    However, if you are looking for new middle end PC, Core i5 is your must consideration
    The future CPU and 32nm manufacturing technology will bring you more visions :)
