    GA-EP43-DS3 bios settings advice

    I'm can't get my Corsair memory working with the Gigabyte GA-EP43-DS3. It's not on their official support list but I guess it should work with the right settings.

    It'll boot and the memory is recognised but Vista is behaving oddly. Taking ages to open winodws, close programs, blue screens etc. The memory is good according to memtest.

    Here's my current settings, most stuff was set at auto. I'm not looking to overclock for now, just looking for a stable system...

    Motherboard: Gigabyte GA-EP43-DS3, Rev 1.0, Bios F9
    Cpu: E8200

    Re: GA-EP43-DS3 bios settings advice

    This should help get your system stable:

    The following settings should be set after you have loaded Optimized settings:

    PCI Express Frequency (Mhz) --------------- : [Auto] <--- set to 100

    Performance Enhance ------------------- : [Turbo] <--- set to Standard when overclocking
    Extreme Memory Profile --- (X.M.P.) --- : [Disabled] <--- Leave this Disabled

    Motherboard Voltage Control
    CPU
    CPU Vcore --------------- 1.????? ------ : [Auto] <--- set to the 1.????? value displayed in your bios
    CPU Termination ---------- 1.200V* ----- : [Auto] <--- set to the value displayed in your bios (Auto over-volts this too much when overclocking) Auto is OK if not overclocking
    CPU PLL ------------------ 1.500V* ----- : [Auto] <--- set to the value displayed in your bios (Auto over-volts this too much when overclocking) Auto is OK if not overclocking

    MCH/ICH
    MCH Core ---------------- 1.100V ------- : [Auto] <--- set to 1.20 for 2x2GB ram (1.24 - 1.26, or 1.05 might be needed)

    ICH I/O ------------------ 1.500V ------- : [Auto] <--- set to the value displayed in your bios
    ICH Core ----------------- 1.100V ------- : [Auto] <--- set to the value displayed in your bios

    DRAM
    DRAM Voltage ------------ 1.800V ------- : [Auto] <--- set to the max rated ram voltage (for most memory)

    Advanced Settings -------- The following settings will improve system stability for overclocked systems.
    Limit CPUID Max. to 3 -------------------- : [Disabled]
    No-Execute Memory Protect -------------- : [Enabled]
    CPU Enhanced Halt (C1E) ----------------- : [Disabled]
    C2/C2E State Support -------------------- : [Disabled]
    x C4/C4E State Support ------------------ : [Disabled]
    CPU Thermal Monitor 2 (TM2) ------------- : [Enabled]
    CPU EIST Function ----------------------- : [Disabled]
    Virtualization Technology ----------------- : [Disabled] <--- Enabled if you use Vmware/Virtual PC

    Integrated Peripherals
    Legacy USB Storage Detect --------------- : [Enabled] <--- set to Disabled when overclocking (this must be enabled to flash or boot from a USB drive)

    These settings will eliminate many mobo problems unless there are hardware and/or cable connection problems.

      Re: GA-EP43-DS3 bios settings advice

      Thanks for the reply.

      Ok, I loaded the optimized defaults and followed your recommendations but I'm still getting BSODs in Vista. The last one was SERVICE_SYSTEM_EXCEPTION.

      My updated settings look like this...

      Motherboard: Gigabyte GA-EP43-DS3, Rev 1.0, Bios F9
      Cpu: E8200
      Ram: Corsair, Part# TWIN2X4096-8500C5, http://www.corsair.com/_datasheets/T...096-8500C5.pdf
      Power Supply Unit: OCZ 500W Mod XStream Pro PSU

      Default settings for new setups that are not overclocked.

      note: replace all ?? with the value displayed in your bios.

        Re: GA-EP43-DS3 bios settings advice

        With 2x2GB of memory, MCH Core often needs to be increased.
        CPU Termination --------- 1.200V ----- : [1.200V] <-- 1.22 - 1.26 usually works, sometime memory will only work with 1.05 volts

        Try increasing MCH Core one step at a time.
        Are you using Memtest86+ for memory testing?
        Are you checking for system stability using Prime95, OCCT, Orthos, or Intel Burn Test (IBT)?
