    Default Need help with new OCZ2G10664GK

    I just received my RAM today that I had previously posted about in the past and had RMA'd.

    MotherBoard: Gigabyte GA-EP43-DS3L
    CPU: Intel E8400 3.00 GHz @ 3.6 GHz
    Video Card: Sapphire 3850 512 MB PCI-E
    Power Supply: Case Tools 580 W
    RAM: 4 GB of OCZ2G10664GK

    I am having the same problem as before when I posted here the first time. I can use 2 GB of any type of RAM whether it be my Kingston RAM or this OCZ RAM but as soon as I pop in 4 GB my computer boots up and just freezes randomly. Sometimes it will run hours and sometimes will run a day and then it just freezes. Please help me.

    P.S.
    Also,these are the only settings thus far that I have actually made it a full 4 hours without any random freezing occurring and making me want to pull my hair out.

    With 2x2GB of memory at 800 MHz, try setting MCH Core manually to 1.05 volts. If that doesn't work, set it to 1.20 volts. It's possible that 1.0 volts will work if you set it manually. FYI 1.10 volts is the default, but with the AUTO setting, there's no way to know what the actual setting will be.

    ** edit ** Have you done any stability testing using MemTest, Prime95, OCCT or Orthos?

    Did you run any of the stability tests for AT LEAST 6 - 10 hours? If yes, which ones.

    Take a look at the this thread for a stable o/c. Note that the cpu host frequency is set at 401 MHz. Sometimes there are issues when the setting is set at 400. Manually set the STATIC tRead VALUE to 8 for both channels.

    You can also try setting the SYSTEM MEMORY MULTIPLIER TO 2.00B.

    Have you tried altering the MCH volages yet?

    ^^ All sound advice for sure ^^^

    If you still have issues please give me a screenshot of this program so I can see what all those Auto's are actually giving you and then I will advise back >>
    Tweakers.fr ~ Memset

    You MUST Find and set your own stable voltage for Vtt (Termination) And CPU PLL when overclocking. I would advise you try 1.225-1.25 Vtt (Only for the above mentioned settings, and CPU PLL of 1.5-1.54

    Well I have had my MCH Core all the way up to 1.300V and still I got random freezing.

    You haven't posted how many of the suggested modifications you've tried.

    Tweaking and troubleshooting can be a royal PITA. There are no shortcuts. In one similar thread, the 2x2GB sticks ran fine when underclocked from 1066 to 800 MHz. Replacing the memory with another brand fixed the problem. In a different thread, replacing the mobo fixed the problem. Usually the problem is with improper bios settings.

    To save yourself time & aggravation, I suggest the following:

    1) Load optimized defaults. You'll be testing with standard settings for your cpu and memory.
    2) Only change the following in the bios:

    -- CPU Clock Ratio ..........................: [9 x] <===== (leave at default setting)
    -- CPU Host Clock Control..................: [DISABLED]
    -- PCI Express Frequency (Mhz) .........: 100 <====== (not AUTO)

    1) With these settings, do NOT boot into windows. Run Memtest86+ for at least 10 full passes. Overnight is even better.
    2) If there are no errors, reboot in Windows and run PRIME95, OCCT or Orthos for 6 - 10 hours. Given your computer problems, I would individually run all 3, one after the other.

    If there are errors in any of these Windows programs, post back with your full bios configuration and a screen shot of Memset memory values and include a screenshot of cpu-Z.

    Once your system is stable, we can better help you reach a stable overclock.

    Which bios version are you currently using?
    Which operating system are you running?
    How long has the operating system been running?

    Well my memory frequency shows 800 MHz automatically when I enter the BIOS so I have to set the multiplier manually to get it to say 1066 MHz based on whatever I have my CPU frequency at. I set the timings manually to 5-6-6-18. I will try later on tomorrow to set the specified MCH voltage to 1.200 V. Is there a possibility this RAM "will not" work no matter what I try on this Mother board. Reminder: my mother board is Gigabyte EP43-DS3L.

    Which cpu cooler are you using? If it's the stock Intel heat sink, this will limit you overclocking due to inadequate cooling. What are your Vcore temps (idle & load) when you're running in windows?

    Your EP43-DS3L might have problems running 2x2GB @ 1066. Can you try another brand of 1066 memory. From your first post, you have the same problem with Kingston and OCZ.

    MCH = 1.20 volts is the minimum USUALLY required with 2x2GB. Some have found that 1.05 volts works with 2x2GB. You might need to increase MCH to 1.22 or 1.24 volts.
    Have you manually set CPU Vcore to the value displayed in the bios. Leaving this setting on AUTO might be causing your problem.

    Manually set Static tRead Value = 8
    Once stable, you can probably set it to 7 for better performance.
    tRFC = AUTO should be used until your system is stable.

    Try each of the following options to see if there is a memory compatibility issue with 2x2GB when your cpu is at 400 MHz:
    - Memory multiplier = 2x, memory speed at 800
    - Memory multiplier = 2.4x, memory speed at 960
    - Memory multiplier = 2.50x, memory speed at 1000
    - Memory multiplier = 2.66x, memory speed at 1064

    Other settings you can try are:
    cpu = 333, multiplier = 3.2x, memory speed at 1066
    cpu = 350, multiplier = 3.0x, memory speed at 1050

    You'll need to run Memtest86+ and one of the widows stability tests for at least 4 - 6 hours each to ensure that your system is stable.

    Some owners have solved their boot issues and/or memory problems when they switched to a different brand of memory.

    Your EP43-DS3L might have problems running 2x2GB @ 1066. Can you try another brand of 1066 memory. From your first post, you have the same problem with Kingston and OCZ.

    MCH = 1.20 volts is the minimum USUALLY required with 2x2GB. Some have found that 1.05 volts works with 2x2GB. You might need to increase MCH to 1.22 or 1.24 volts.
    Have you manually set CPU Vcore to the value displayed in the bios. Leaving this setting on AUTO might be causing your problem.

    Manually set Static tRead Value = 8
    Once stable, you can probably set it to 7 for better performance.
    tRFC = AUTO should be used until your system is stable.

    Try each of the following options to see if there is a memory compatibility issue with 2x2GB when your cpu is at 400 MHz:
    - Memory multiplier = 2x, memory speed at 800
    - Memory multiplier = 2.4x, memory speed at 960
    - Memory multiplier = 2.50x, memory speed at 1000
    - Memory multiplier = 2.66x, memory speed at 1064

    Other settings you can try are:
    cpu = 333, multiplier = 3.2x, memory speed at 1066
    cpu = 350, multiplier = 3.0x, memory speed at 1050

    You'll need to run Memtest86+ and one of the widows stability tests for at least 4 - 6 hours each to ensure that your system is stable.

    Some owners have solved their boot issues and/or memory problems when they switched to a different brand of memory.
    I have a different heatsink for my CPU. At 3.6 GHz the highest my temps ever get is 38. Maybe 40 eevry now and then. At idle I run around 30-34. These temps are coming from real temp. My MCH Voltage only goes up in intervals of +.100. Example: my first option would be 1.100 then it goes up to 1.200, etc.. I set my CPU Vcore manually to 2.5625 which is one notch above 2.5000 just for "stability" and to be safe with my overclock. I will try and set the tRead values to 8 later on and set the MCH voltage to 1.200 and see how that goes. Oh and just to throw this out there, I tried 1.300 V for MCH voltage once and my computer wouldn't even post. It would turn on along with the fans and the hard drives but would just not do anything, so I set it back down to auto and left it alone because that kinda scared me.
