regarding the last few "my 2 cents" posts ....
I couldn't agree with you guys more on the majority of these issues being more along the lines of user related issues.... Thinking about the most common issues associated with this board .. and in no particular order...
1) PSU Issues.. folks choosing to use "case supplied" PSUs that simply can't deliver what is required on the 12v rail(s) or others... or using a PSU because it was "awesome" in their older non-SLI rig.. SLI is the biggest offender here, but you now use more and more drives, USB devices, etc.. all of which have raised the demand on the psu.. Asus has outlined in its manual some general rules of thumb regarding what you'll need depending on the SLI config, # of drives, etc.. but most people just zip over it and wonder why they have issues posting, or with recycling, etc..
2) inability to overclock beyond 245-250fsb using 1T.... we all hate this limitation.. and hopefully it wil be addresses with a bios fix in the upcoming weeks as others have noted.. But the bottom line is that this is an overclocking issue.. and there are no guarantees when overclocking ... anything beyond 20-25% is pushing the envelope... but technically the board is working as advertised..
3) SLI Issues... these tend to be more graphics driver related with .... Once again, this is bleeding edge stuff.. with little widespread usage to date.. so as more folks start exploting, I'm sure you'll see more driver fixes upcoming...
4) corrupted data w/NCQ ... I believe these also proved to be an nforce4 driver issue as well, rather than one with the board.. and they were addressed with the 6.39 drivers...
5) problem with dissappearing drives? seems to be related to the drive manufacturers firmware... (or am I confusing this with another issue?).. In anycase.. firmware is the drive manufacturers issue.. not the mobo...
6) chipset fan... ? I've seen a small handful of posts on failures with this fan.. but I am not sure how frequent this is occurring.... It would seem ASUS may have done better to go with a passive heatsink type design.. time will tell..
7) Inability to post... this is a biggie with many folks.. This is one of those that I gather is in many cases user related.. though I don't doubt that a fair number of failures are also mobo related... I suspect most of the user problems relate to incorrect memory choices, inadequate PSU's, incorrect bios config choices, or just plain installation/assembly erroes, etc...
.. there are others.. but these are the ones I've reeled off the top of my head.. Bottom line, as others have stated is that you need to do your homework.. The PSU and memory choices are very important with this board.. with SLI comes a whole new set of requirements on your psu, and ASUS boards (particularly the nforce chipsets) have always been finicky when it comes to memory sticks (dual channel doesnt help!) not to mention their issues in the past to delivery sufficient voltages to all parts of the board for overclocking (which have caused the OCers much frustration) Bios fixes often correct or improve these issues... but we've also seen the need for new board revisions as well, indicating design issues..
.... look at it this way .... if it was easy.. it wouldn't be much fun or or as rewarding!!
