    Re: Issues and problems EP45-UD3R

    Excellent.

    It's always best IMO to get rid of as many auto settings as possible. This means you're able to tune performance to what actually works best rather than what the board thinks. It's also been known to happen that the values the BIOS says it's setting don't actually match what is really set. Rare but possible. Advanced RAM timings are 99% of the time stable on auto (tRead may need a tweak) and the main benefit of setting these is to squeeze a drop or two more performance out of the system.

    VDIMM is another name for DRAM Voltage. As long as you have it set to the spec of your RAM (usually stated on the packaging or the sticker on the module) then you have it correct.

    Let us know how you get on stability wise. You may want to run a program called Intel Burn Test to roughly verify stability. Set it for 5 runs on maximum stress and in a few minutes it can tell you if you are in the realms of stability. Running Prime95 over night on "Blend" for a min of 8 hours would be a more thorough test IMO. 8 hours should be fine for general purpose stability and gaming etc. Only do more if you're an overclocking enthusiast or do alot of distributed computing, like Folding@Home, where it's crucial the data you send is 100%.

      Pass at standard and Maximum. But running has not been the issue, only booting.

        Short lived success, still won't boot first time.

          I suggested the stress tests because although you may be able to use the machine fine, there are certain levels of instability that may not show up until for example 14 hours of Prime95. This may be the same issue that also prevents a system from booting first time.

          Usual suspects are auto settings (which are detected each boot). Things like RAM timing (inc tRead) are the most likely.

            Psycho101,

            Thanks for the help, but in the end this board is going back. I just don't have any more time to spend figuring out why something doesn't work (not to mention my window for return means this needs to be in the mail by tuesday/wednesday). And while since it is fine once it boots I have a wedding to finish with, I've spent too much time on this already.

              That's fair enough.

              Let us know how you get on, and if the different model/brand of board has solved your problem. I hope it does.

                Well I hate to say it, but the answer for me seems to be Asus. I return EP45-UD3R and got an Asus P5Q. It's been up and running for 1.5 days, no issues. In fact a few things I thought were related to Win7 RC (some programs crashing and such) have also gone away. I have not gotten into any tweaking yet (but I'll only do the very basics anyway). But this build was much more like the GA-EX38-DS4 build before it. It just woked out of the box.
