    Default GA-EP35-DS3P with 2X2GB RAM-Can't get it stable!

    Hi,
    First post!
    I have an EP35 motherboard (F6 bios) which I'm tearing my hair out trying to get it stable with 4gb ram (2x2gb modules).
    Each stick runs alone in any slot without any errors but adding the additional stick causes the system to freeze, particularly when rendering videos. CPU is Q8200 stock speed. graphics card NVDIA GeForce 9600GT 512MB.

    I've tried 100 different combinations of settings but I think I must be missing something.

    The RAM sticks are 2 identical 2GB Corsair xms2 DDR2.
    CM2X2048-8500C5C
    1066MHZ 5-6-6-18 2.10V ver1.2
    Any other info you need please let me know.


    Thanks so much for your help!

    With 4GB of memory, increasing (G)MCH OverVoltage Control might solve the problem.
    The Normal setting probably sets this to 1.10 volts.
    You probably need a setting of 1.20 - 1.24 volts, and possibly up to 1.26 volts.
    Manually set DDR2 OverVoltage Control to the maximum rated voltage for your memory, probably 2.10 volts.
    The default memory voltage setting is 1.80 volts.
    You should already be running with Optimized Bios Defaults loaded.
    Pages 50 and 54 in your motherboard user manual describe these bios options.

    If these settings don't solve your problem, post your current bios settings using the bios template from Gigabyte BIOS Templates (To Give Us Your Settings), post #4.
    Copy the P35 bios template into NotePad or any plain text editor, and accurately fill in your current settings and post your bios settings.
    Ignore the bios settings in the template and fill in your settings which might include Auto, Normal, or numeric values.

    **edit**
    At the main bios screen, press CTRL + F1 to display any hidden bios settings.

    The following is an example of a filled in bios template.
    Don't use this example for any of your settings.

    Default Re: GA-EP35-DS3P with 2X2GB RAM-Can't get it stable!

    Thanks for your reply. I actually wrote a reply a few hours ago and only see now my post didn't submit-weird.
    Anyhow, I have most settings at stock but I'd like to clarify something:
    The ram sticks are rated at 2.10v and the assumption seems to be that my board gives 1.8v to ram yet whether I leave the DDR2 OverVoltage Control at normal or set it to +3 it always says the ram voltage is 2.144 in PC health. Could it be the board detects the correct ram voltage automatically?
    Also I don't see any additional hidden settings by pressing ctrl F1-which settings specifically should appear and maybe I'm not doing it right?
    Thanks

    Will submit full settings soon....

    *EDIT*

    Adding more Northbridge voltage becomes unstable.

    Here are the settings:

    CPU = Q8200
    Motherboard = GA-EP35-DS3P

    Pressing CTRL + F1 at the same time will display hidden bios settings that will vary by motherboard model.

    Did you try (G)MCH OverVoltage Control [+0.200V]?

    With System Memory Multiplier (SPD)____ [Auto], change the Auto setting to 2.40 which will give you a memory speed = 800MHz.
    If your bios allows for finer adjustments such as increasing by +0.025, try increasing starting from +0.100.

    Post a cropped screen-shot using 4 cpu-z windows at the same time that show the CPU, Mainboard, Memory and SPD windows.
    Don't post post a screen-shot that includes your complete desktop.

    Default Re: GA-EP35-DS3P with 2X2GB RAM-Can't get it stable!

    Increasing northbridge voltagedoesnt help at all, if anything it gets less stable the higher the voltage. I've tried it at 800mhz but doesn't make a difference.

    Strange thing is that I've been running memtest now on 1 stick alone and memtest freezes shortly in on all settings except auto for everything.
    I have a feeling the 5-6-6-18 stated on the sticks isn't entirely accurate for all cases.

    Could it be that more voltage is needed in principal but somethings overheating (eg the northbridge) when the voltages are upped?

    Will post screenshots later.
    Thanks

    Clear your CMOS with a jumper block connected to the CLR_CMOS pins for 10 minutes with your system turned off and your power supply's A.C. cable disconnected from the wall outlet. Boot using only one memory module in memory slot #1, go into the bios, load Optimized Bios Defaults, and save settings and exit. Re-run Memtest86+ v4.2 and note the displayed memory settings.

    Have you made any recent changes to your system?

    No recent hardware changes made.
    I removed 1 stick, cleared the cmos as you suggested, loaded optimized defaults and memtest ran 2 passes without errors as so:



    However when I add the other stick memtest freezes after 10 seconds or so and I tried with normal, +.025, +.05,+0.1 on the (G)MCH OverVoltage Control which makes no difference.

    memtest with 2X2Gb as so:



    CPU-Z screens as requested after optimized defaults with 1 stick of 2GB:

    Make the following changes to your bios:
    Code:
    PCI Express Frequency (Mhz)_______ [101]
    
    System Memory Multiplier (SPD)____ [2.40]  for 800MHz
    
    CAS Latency Time________________ 5
    Dram RAS# to CAS# Delay_________ 5
    Dram RAS# Precharge Delay_______ 5
    Precharge Delay (tRAS)__________ 18
    
    Static tRead Value_________6____ [6]
    
    DDR2 OverVoltage Control______ [1.90]
    (G)MCH OverVoltage Control_ [+0.100V]
    CPU Voltage Control___________ [1.20]
    
    Integrated Peripherals
    Legacy USB Storage Detect___ [Disabled]
    Test with both memory modules installed and note how long Memtest86+ runs without errors.
    If there are no errors, let the test run for at least 5 - 10 loops.
    If there are any errors, repeat the test but lower (G)MCH OverVoltage Control one step at a time (0.025v) until it is back to the default setting. IF there are no errors or freezing, boot into windows and see if your system is stable.

    Sorry, DDR2 OverVoltage Control should be set to +0.10
    You should be able to set the Cpu Voltage to a specific value and not use an offset voltage, such as +0.10
