    Default EP45-UD3LR with Q8300 optimization

    Hello :)
    Thanks profJim for helping me about opening this thread.
    I would like to ask about optimizing my system while working with multi utilities, such as firefox with many tabs with autocad with etc etc.
    Also with games, I want to figure out what would be my best optimal system configuration. I'd like to glad if I can get any help.

    so here are my questions:

    * I got a Samsung SyncMaster 997MB monitor, it gives 85Hz@1280*1024, but 75Hz@1600*1200, I want to use it at 1600*1200 but not sure about my eyes' stability so what you guys suggest? I am a bit afraid about that 75Hz.

    * Ofcourse my system optimization here we go :) What would be the best settings with Overclock and non-overclock?

    Nice post, you have provided excellent information.

    Save your current bios settings using F11 at the main bios screen. Give this setting a name such as Default_Setup. If you want to load these settings, use F12 from the main bios screen and then select the name of the profile you want to load.
    This post has some useful information that deals with bios profiles and possible problems with new bios settings.

    We'll start with an optimized setup with stock settings. If you have already loaded Optimized bios settings you're ready to go:

    Note: this template shows the "normal" or default values to the left of the colon (:) and manual setings or AUTO is shown to the right of the colon.
    After you have modified your bios settings, save the new settings as an additional saved profile using a profile name such as Optimal_Default.

    I suggest that you run Memtest86+ from a bootable floppy or cd for at least 6 - 8 passes before you boot into windows.
    After Memtest86+ runs error free, I recommend that you run the following stability tests:

    • Intel BurnTest (IBT) or LinX for 10 loops using the maximum amount of available memory.
    • Prime95 Blend test for at least 8 - 12 hours or longer.

    If there are any errors while testing, tell us how long the test ran and what error messages were displayed. Don't continue to run the test if there are any errors.

    Code:
    CPU = Core 2 Quad 8300 (SLGUR) (7.5x333) 2.5GHz 
    Motherboard = GA-EP45-UD3LR , Revision 1.0

    Should probably be good for around 3.7Ghz at the other end,depending how happily the memory will run.

    Is this really correct?? I thought it was supposed to be 900mV for the CPU clock drive?? Did you load optimized defaults after you flashed you BIOS?

    The 800/800 settings are the optimized settings on some boards, like the EP43-UD3L (I think).
    It might be the same for the EP45-UD3LR. I don't know for sure.

    So far I got my Memory Bandwith improved by 0,2 GB/s (6,73GB/s) atm
    Cache & Memory 1,5GB/s improved (36,68GB/s)
    And Memory Latency reduced so is improved too by 2ns (it was 91,5 before and 89.4ns now)
    but other stuff like video and cpu tests seems like to have around same values.
    I ran memtst86+ like 6tests but didn't got prime95 blend yet.
    Gonna try if I got some more time.
    But what should I do if I want a overclock with cpu?
    or Rams or VGA?

    and using monitor at 1600*1200@75 is better than 1280*1024@85 ?

    thanks a lot for all help so far!
