    Exclamation EP45-UD3R boot loop

    I've had this problem for a while now, nothing is overclocked. I originally thought it was a bad PSU, but even on a new PSU it does the same thing.

    The only thing that stops it from happening, is by me doing a CAP discharge before use. I've already tried loading optimized defaults, nothing seems to help. Am running RAM at 2.1v mfgr recommends vs the 1.8v default. I don't think that is affecting it though.

    Full specs in sig, any ideas what could be causing this? I've been wanting to OC for a while now since I have good temps, but wouldn't feel comfortable starting while I still have no idea what's causing this problem.

    EP45-UD3R v1.1 (F12) | E8500 | ZALMAN 9700 NT | HD 5770 | 8GB DDR2 1066 5-5-5-15 @ 2.1 | Antec 900 | Barracuda 1TB | Win7 Ult x64

    With 8GB of memory, optimized bios settings alone probably won't work.
    See if your system boots OK with only one memory module installed in slot #1.

    Make sure that optimized bios settings are loaded.
    Enter your bios and apply the settings in this post.
    You might need to increase DRAM Voltage to 2.12 or a bit higher.
    MCH Core voltage will probably need 1.28 - 1.32 volts.

    If you're having trouble with 8GB, try running with only two memory modules installed in mobo slots 1 & 3, and run Memstest86+ (v4.x) for at least 8 - 12 full passes.
    Then follow steps 2 - 4 in the post to provide additional information, including accurately filling in the generic bios template with your current bios settings.
    Copy this EP45 template into Notepad, fill in your settings and then post your settings along with the screen-shot information in step 4.

    System instability and/or boot loops are often caused by improper MCH Core, or memory settings that are too tight (i.e. too low).

    **edit** In many cases, 8GB of memory needs to be under-clocked somewhat for stability. You might have to run your memory at ~ 1000MHz or a bit lower.

    Thank you for the reply, good sir. One thing I will post before I gather all the information you requested, this is the memory I'm using...

    Newegg.com - G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory Model F2-8500CL5D-4GBPK - Desktop Memory

    I am running it at specifications for timings and voltages, I don't doubt your wisdom by any means, but will increasing voltages higher than recommended be a problem for this memory? I am thinking no, not by the amount you suggested, but I am a novice when it comes to MB tweaking/overclocking, so am a little cautious.

    One more thing I'll also post, because I thought a few values may have been slightly off.

    -Temps & Voltages for point of reference


    -Timings for RAM, which seemed a bit off after reading Memory Timings sticky

    Begin with setting Performance Enhance standard and MCH Core 1.2v.
    Increase MCH Core if needed, up to 1.28v should not be a problem, absolute max spec by Intel if I remember correctly is 1.32v.
    Also you can try and set Static tRead Value manually for both channels, try 7 or 8. Then try and lower it later when the boot loop is resolved.

    Updated with new screens. Will try to get BIOS screens in 10-15 min.

    Caution is good, Keep in mind that sometimes a post will contain a typo where the value is way out of line. Me? Never!! Uh....except the time....oh, never mind.

    Some memory modules rated at up to 2.10 volts run best at somewhat lower voltages, such as 2.00 volts. Most setups use 4GB of memory. When using 8GB, memory voltage settings often need to be increased somewhat.

    I don't advocate over-volting memory, but sometimes it needs to be done to gain stability. Keep in mind that running your memory at 2.14 volts is only 1.9% over the maximum rated voltage. You're using excellent memory, so a 2% over-volt setting (if needed) is well within safety margins. If you look at the "minimum" column in HWmonitor, you'll see that 2.08 volts is the lowest reading for your memory voltage. I have some doubts about the accuracy of software voltage readings, as they're only as good as the mobo chip that reports these values. You would need to use a DMM (Digital Multi Meter) to verify the actual voltage readings used in your system at any given time. If you have a high quality psu, I seriously doubt that your 12 volt readings are really running in the 12.42 - 12.54 range. Most higher end power supplies provide voltages that are within 1% - 3% of the 12.0 volt specification (11.64 - 12.36 volts) under all loads at all times. The official spec is plus or minus 5%.

    Our goal is to help get your system fully stable. Once you've reached this goal, you can then see if you can lower some voltage settings without causing problems or instability.

    I agree with Chike, accurately filling in the bios template with your settings is much easier for us to work with.
    Be sure to include the requested screen-shot programs, as they allow us to cross check some of your posted bios settings.

    The following values mean that you have loaded Fail-Safe Defaults
    CPU Clock Drive ---------------------- : [700mV]
    PCI Express Clock Drive --------------- : [700mV]
    Do NOT manually change these. You need to load Optimized Bios Defaults from the main bios screen, then enter the MIT section and manually change other bios settings.

    ++++++++++++
    Change the following:

    PCI Express Frequency (Mhz) ---------- : [100]

    Extreme Memory Profile --- (X.M.P.) --- : [Disabled]

    tRFC -------------------68 ---------- : [Auto] <--- this might need to be a bit higher, do this last (if not stable)
    Virtualization Technology -------------- : [Enabled] <--- Disabled if you are NOT running VMware

    Motherboard Voltage Control
    All AUTO settings in this section are not always stable, even with stock settings.
    Apply the recommended settings in the linked to post after you have loaded optimized settings.
    MCH Core = 1.28 - 1.32 should be set as your starting point.
