    I did indeed try your settings, no luck, it still rebooted. Arg, quite frusterating

    Yeah my computer is still having the reboot issue, even with those settings. Although, it does seem to stay up longer than before. I can run memory in dual channel, but it never pasts memtest (fails within a few seconds.) I'm thinking about buying another motherboard and testing all the other hardware on it. Even if it is a bios issue maybe I can find common ground between the two.

    Guys, please post the exact settings you are using that fail, and your spec's if they are not in your Signature and I can help.

    Sounds like you just still need some adjustments, especially you Jumping Fences, sounds like you are getting closer

    Ugh, Rosewill PSUs. It's probably fine, but they've produced a lot of naff units in their time.

    After everything I have done and seeing the system crash +40 times in the past week or so, I think its a memory issue. I've tried every combination of ram placement with 4 different brands and nothing will pass a memtest or prime95 successfully.

    After all the help in tweaking my settings, its easier to find a pattern in the crashes. When I first set the system up it would crash guaranteed within a half hour. Now I can leave it up for a day without any problems. The crashes only occur now when inside a game or running some of the Adobe programs.

    Well with 4 brands of ram used, and now sounds like you are getting closer do you want some more help? If so, please post your full settings and I will see if I can advise you anything more that may help you get rid of those crashes when gaming

    @ndufour, thanks for your specs, now give me the FULL settings you are using that fail and I will advise back

    Sure. Is there any easy/efficient way to do that? I skimmed the topic but couldn't locate it. Should I just copy it down? Also, this problem has been ongoing for some time and I've tried numerous settings, although your post marked the first time I've fooled around with voltages (so I suppose the settings I changed wouldn't have much effect, most likely) and I've updated the BIOS twice >.<

    I'll get back to you as soon as I'm out of the lab and back home.

    Here are my motherboard settings. A number of them were different from the ones you had in your template, even though my mobo is set to "optimized defaults." I've capitalized settings that were distinct from yours in the advanced settings section so they'll stand out.
