    Generally I agree with you. And yes, bad boards come in all brands.

    However, in this particular case, in my experience, this board will BS from as often as several X/day, AND/OR run just fine for a month between BSs - which, to me, is actually WORSE than several Xs/day, because at Week 5, 6, etc, who knows? Will it or won't it? Also, what happens if I want to upgrade a card, RAM, or HD? Tweaking is fine as long as it is an option, NOT a necessity. Not to mention that this board was marketed SPECIFICALLY as a dependable, stable board: "Three-inch copper bulkheads!" "Exotic Japanese capacitors!" Yeah, well...

    I will give it this: - it's definitely one of the prettiest boards I've ever seen...

    Thanks to all who've contributed to this thread. Well for the record I RMAed the motherboard. After installing the replacement (new) EP45-UD3LR motherboard with the original Case, PSU, RAM (one stick only), Graphics Card, and Q9400 CPU I found that I had the same problem as before - i.e. the PC would not POST and would switch itself off and then back on every two seconds. I then replaced the CPU with another new Q9400 CPU and when switched on it immediately POSTed.

    As before I loaded the Optimized Defaults, saved the setup, restarted the PC, and then reentered the BIOS. I then set the System Memory Multiplier to 2.40B to manually set the Memory Frequency at 800 Mhz and then changed the standard timings to 6-6-6-18. I then gradually added back in the RAM sticks until they were all error free after 4-6 Memtest+ Passes each and 3 hours of OCCT testing. I then successfully repeated the Memtest+ testing overnight on all 8GB RAM.

    I have since had the PC up and running the original installation of Windows 7 (64 Bit) for 5 days so far without any problems. I did have to reactivate Windows after a couple of days.

    In hindsight it appears that cause of the problem was the original Q9400 CPU and not the EP45-UD3P motherboard. I'm now in the process of RMAing the CPU and intend using the replacement in another PC... most probably with another EP45-UD3LR motherboard as the other EP45 motherboard models are getting harder to find in Australia.

    Glad to hear that the new cpu has solved your problem.

    Cpu failures are rare, but it shows that sometimes you need to test with other components to find out where the problem is.
