    Default The new conqueror is here, the analysis of Core 2 Quad CPU, QX9770

    I recalled that Intel was just launched its Yorkfield 45nm quad core CPU
    Intel release Core 2 Quad QX9650 333X9=>3G cache 6MB x 2 version to replace the
    65nm QX6850 333X9=>3G cache 4MB x 2.
    Meanwhile,
    the Dual core Wolfdale(45nm) CPU will be launched in market before this month.
    I hope that can improve the issues of high temperature and high power consumption when the system runs under high FSB.

    It really surprise me that Intel releases a higher model of Quad core CPU later on,
    the core 2 quad CPU, QX9770, 400x8 => 3.2G, cache up to 6MB x 2.
    That is the highest end model of the series. Also,
    it is another model that breakthrough 3G after dual coreE8500.

    You guys might know that C2D’s FSB could be reach 450~600MHz.
    Besides, C2Q’s FSB is also can climb up to 400 to 500MHz.
    This is the first in history that Intel set their C2Q processor’s default FSB
    At 400MHz.

    Let’s take a look at our super star, Intel Core 2 Quad QX9770.




    It test with the Motherboard DFI LANParty LT X38-T2R




    Up to now, there is only X48 chipset can be officially supports rated FSB1600 processor.
    Some likes P35 or X38 may occurs problem while the FSB is around 1333/1066.
    But one thing I knew is, most of motherboard manufacturers are putting efforts to fix those BIOS issue of P35/ X38 right now.
    I believe that won’t be a problem soon that P35 & X38 motherboard can support QX9770 stably.

    The specification of the test system
    CPU:INTEL Core 2 Quad QX9770
    MB: DFI LANParty LT X38 T2R
    DRAM:CORSAIR Dominator TWIN2X2048-8888C4DF
    VGA:ELSA 8800GT 512M
    HD:Seagate 7200.10 320G
    POWER:POWER:Corsair HX520W Modular Power Supply
    Cooler:Thermaltake V1

    Frankly, the 45nm process CPU is really having more advantages in overclocking.
    The previous model 65nm process CPU QX6X00 series, the 3.6G with 1.35 to 1.45V is almost shows the excellence of itself.
    The new process, 45nm, brings an obvious improvement in performance.
    I found that QX9x00 series(45nm) CPU is easy to reach 4G stably under 1.4V.

    In fact, I didn’t make any temperature comparison between the heats out from the CPU cooler of 45nm & 65nm CPU.
    But I felt that the heat air out from 45nm CPU is lower than 65nm CPU.
    That is a big improvement on heat dissipation issue than C2D period.

    For my personal opinion, QX9770 is a brand new processor with 400MHz FSB,
    but the OC performance in FSB is a bit not as good as QX9650(with P35 & X38).
    Maybe the reason is something about that P35/ X38 are start at FSB 266/333MHz.
    I really hope that motherboard manufacturer will adjust the BIOS to let QX9770 to perform much better.
    Anyway, I will make a more formal comparison when X48 is launched.
    To see whether QX9770 can performs better.

    In-coming review:
