Asus seems to think it's a problem .... Regardless of you not having run into it, a Google / Yahoo search will certainly confirm the issue and as Asus has officially confirmed the issue, it's gonna be hard to take the position that it doesn't exist. Rec'd an e-mail update on the progress of their investigation this morning. All one has to do is look at the links I provided.... forget the problem and how significant it is, it's the "GM like" response to the problem that concerns me as a long time Asus customer and loyalist.

I think most peeps would be understanding if there had been some better feedback to customers on the issue. The forum volunteers were as helpful as they could be but even they dropped out of participation in the discussion after a while. But at this point, it seems Asus has taken heed and is now actively pursuing a solution. Unfortunately, look at how many "last Asus board I'll ever buy" posts there are in those threads. While I don't agree with that reaction .... just cause there's a Z87 bug doesn't mean there's a Z97 or LGA 2011 bug of that the problem is not correctable with a BIOS update.
Most peeps who use time sync would never be aware of the clock issue.....I had it happen few weeks back and I was off 10 days before I noticed as I spend most of my time on the lappie. I had a user come in with an OS issue and when he brought it in, the BIOS clock was 10 months outta date.... he ever noticed.
I am now more cautious and will hold off getting further invested in Asus Z87 until the issue is resolved or determined not to exist in Z97. Before getting my M6F, I held off after published reports about the controller bug that was fixed with the C2 stepping. There's also the F10 save BIOS changes bug that says you have not made any changes when you just got done doing them as well as the BIOS upgrades borking previously stable OCs.... I think I'm getting a handle on that one....it appears that it's not so much a reduction in the Board's abilities as much as in the way it does things when certain settings are on Auto. I am getting close to my originally stable OCs that I had under 0804 but with significantly higher VID, VCC Ring, VCCIN (Ev) and DRAM voltage settings.
Look at any component and you will see that every company makes a dud once and a while.... over at storagereview.com database which tracks HD failures, the drive model with the lowest failure rate and the model with the highest failure rate is the same company (Seagate). Many companies produce very excellent products, every company produces a bad or buggy product now and then. Corsair sells some excellent PSUs, Corsair sells some pretty good PSU and Corsair makes some PSUs I wouldn't put in an $850 budget box. No component is "best" simply because of the logo they put on it.....
Yes, I'm well aware of your opinion of MSI and I can only assume nothing has changed in this regard .... AFAIK you still have not built a box with any of the newly designed MIL Spec MSI boards and, as I recall, from past thread(s), you don't intend to unless MSI gives you a free board for the purposes of changing your mind and you have also indicated that you don't trust web reviews / findings / published specs and component lists no matter how reputable the site.
While you are certainly entitled to have an opinion, the weight of any opinion to a reader such as myself must be weighed on the evidence provided and there remains nothing documentable that you have provided that I can look that supports this position. And given your chosen avatar, it's hard to view this opinion as impartial. I'll end it on that note as we've "been there done that" and I don't think myself or any other readers will be benefit by rehashing the exchange again.
