    Default GigaByte GA-X48-DQ6 Voltage / Vdroop problem

    Greetings,

    Recently ( about 2+- months ago ) I purchased a brand new set of components for gaming use. These are:

    - GigaByte GA-X48-DQ6
    - Intel C2D E8400 Socket 775 @ Artic Cooler Pro
    - Sapphire Radeon HD4850 @ Crossfire @ Thermaltake DuOrb + VF1000@LED
    - Samsung Spinpoint F1, 7200RPM, SATA II, 32MB, 1TB
    - G.Skill F2-6400CL5D-4GBPQ, 4096MB, 800MHZ DDR2


    I've recently upgraded the Bios to the latest stable version aswell ( 8 if i remember correctly )

    But, i'm encountering a few problems with overclocking.

    First of all,

    If i leave the voltage management at automatic it's putting the Vcore way to high!

    At 4,0ghz according to the GigaByte GA-X48-DQ6 apprently it needs an excesive 1,57 Volt.

    Due to the fact this is way beyond what anyone recommends, how are these voltages descided? is it based on my setup or a general thing that someone at Gigabyte descided?

    Second, which is similair in a way but what the heck ;)

    When doing the voltages manual, i find myself having a fairly major ( even with auto on the voltages , obviously ) Vdrop. at stock, the Vdrop is between 0,05 - 0,10. Could this indicate a component isnt working as intended?

    Also, i'm required ( for a more then resonable 3,8ghz ) to put the Vcore around 1,38 - 1,40 whilst plenty of others have no trouble getting their mhz up a whole lot without increasing their Vcore for alot.

    Could this indicate something about any of my components, especially the big Vdroop and high voltage requirements for ( relative ) minor overclocks?

    Many thanks in advance.

    I think sometimes its just your CPU. I need 3.8v for 3.6ghz.

    UMM.. 3.8?... Lol.. No.. Typo demon!

    My e5200 requires 1.45 to get 3.9Gghz stable and I experience Vdrop as well...

    Can a proper PSU change the outcome of any of my problems?
    Since i currently have a B-brand 550 WATT ( Eminent, might even be a "C" :( )

    Anyone els has any idea about the Voltage / Vdrop problem?
    Especially why im requireing so much ( relatively seen ) voltage then 99% of the world. Just bad luck? :)

    Added note, with the current settings it seems relatively stabile.
    Only Intelburntest, with 5 "tests" shows at the end 1 out of 2 tests finished, and the other one failed.

    I'd really like your input on this Lsdmeasap, perhaps you see something wrong :) with the above settings.

    Here would be optimal settings for your setup to overclock to what you have, and more >>>

    Code:
    Robust Graphics Booster___________ [Auto or Fast]
    CPU Clock Ratio ____________ [9] 
    Fine Clock Ratio ____________[Disabled with the latest Bios ( 8A ? )] ?? I say too! ??  Maybe you should go back and not use a Beta BIOS
    
    CPU Host Clock Control_ [Enabled]
    CPU Host Frequency (MHz)__________ [423] 
    PCI Express Frequency (Mhz)_______ [100]
    C.I.A. 2__________________________ [Disabled]
    System Memory Multiplier (SPD)____ [2.00B or 2.00D]
    DRAM Timing Selectable_______ SPD __ [Manual]
    
    Performance Enhance = [Standard]
    
    CAS Latency Time________________ 5
    Dram RAS# to CAS# Delay_________ 5
    Dram RAS# Precharge Delay_______5
    Precharge Delay (tRAS)__________ 15
    
    ACT to ACT Delay (tRRD)_________ 3-4
    Rank Write to READ Delay________ 3-6
    Write to Precharge Delay_________ 4-6
    Refresh to ACT Delay______________ 52-62
    Read to Precharge Delay__________ 3-5
    Static tRead Value_______________ 6/7-10
    Static tRead Phase Adjust________ [Auto] << Always Auto
    
    CPU/PCIEX Clock Driving Control [800mV]
    CPU Clock Skew Control [normal] 50 may help
    GMCH Clock Skew Control [Normal] << 50-150 may help with stability
    
    System Voltage Control____ [Manual]
    DDR2 OverVoltage Control__ [+0.05V] << Way to much  Your ram is rated (Warrantied) for 1.8V-1.9V.  I would use 1.9V-2.0, What you have +0.5 = 2.3V 
    PCI-E OverVoltage Control_ [+0.00V] << +0.1 for stability 
    FSB OverVoltage Control___ [+0.00V] << +0.1-0.15/0.2 for stability
    (G)MCH OverVoltage Control [+0.00V] << +0.2-0.3 for 2x2GB ram
    CPU Voltage Control_______ [1.36875] (1.25-1.34 ACTUAL Should get you 4Ghz)
    
    Limit CPUID Max. to 3.....................: [Disabled]
    No-Execute Memory Protect............: [Enabled]
    CPU Enhanced Halt (C1E)................: [Disabled] 
    CPU Thermal Monitor 2(TM2) ...........: [Enabled]
