    Did you lower the CPU VOLTAGE?

    At 367 MHz, you are overclocking your cpu 10%, and should be able to run at the standard CPU voltage. Manually set your voltage to the stock VID for your cpu. Do NOT use AUTO or NORMAL for this setting.

    Before you test again, verify that your memory is fully seated in their slots. Also re-seat all motherboard connectors and PCI cards.

    I suggest that you back down to non-overclocked settings where you are running at 333 MHz. At this speed, you can use the 4.0B memory multiplier to run your memory at its 1066 rated speed with 5-5-5-15 settings.

    When you reply with your results, include the current bios settings that you've applied. If we don't know the current settings, we can't properly advise you what needs to be changed.

    At this point, you should run Memtest86+ for 5 - 10 full passes to verify that their are no memory errors.

    If these settings work, use your computer for several days to verify that everything is stable. You'll also want to do stability testing with Prime95, OCCT, and/or Orthos for 6-10 hours for each test. I run each of these tests overnight.

    Time consuming? YES! There's no shortcut to setting up a stable system. Once everything is stable, you can start overclocking in small (10 MHz) increments and repeating the stability tests.

    Oddly enough, I set the ram from 881 to 918 Spd in the bios by picking a higher strap setting. Since, I have done that at 5-5-5-15 speed and everything else auto, the computer has been completely stable. Does this make any sense. All i can imagine is that the auto settings at that FSB were too aggressive.

    At 881 MHz you're using the 2.40B memory multiplier [367 x 2.40].
    At 918 MHz you're using the 2.50A memory multiplier [367 x 2.50].

    You should immediately save your current stable configuration in your bios profiles. I suggest giving it meaningful name such as: 250A367x918auto
    You can save up to 8 different bios profiles.

    Leaving some of the memory settings or voltages on AUTO puts you at the mercy of the mobo's algorithms, for better or for worse. This is why LSDME suggests specific manual settings. If a configuration fails, you can easily test for improved stability and/or performance by changing one setting at a time.

    When you've altered your settings, you need to tell us all the settings that have changed. For example, are you still running with your excessively high CPU voltage? Did you change the voltage when you changed the memory multiplier? In some/many cases, excessively high voltage can cause instability and/or reboot problems.

    Once you've performed full stability testing, you can try for increased system performance. With the proper manual settings you might be able to run with 355 x 3.0A with a memory speed = 1065, or possibly a bit higher.

    My memory runs stable with 459 x 2.40B = 1101. My best overall performance is with 494 x 2.0D = 988, with tRD = 9 and tRFC = 48. My latter configuration is about 5% faster in real world performance. This is comparing apples & oranges, as we are running different cpus. I'm severely limited by my cpu's maximum 7x cpu multiplier.

    With many of your settings on AUTO, you're system will still not be running at optimal performance levels. For example, manually setting the proper STATIC tREAD and tRFC values will have a noticeable impact on overall system stability and performance. These settings will not necessarily be identical at all cpu and memory settings/straps.
