My only reply to your comment is LOL!!!
To others wondering about what my links are they would be a review of the Gigabyte UD9 vs the Asrock Extreme6 motherboards with test results included and in the review the Asrock motherboard is the one that rules which is a good reason to why not rely on brand names. ^^
As we know Gigabyte's UD9 is the superior motherboard so if it lost to the Asrock Extreme6 it's clear that the UD7 would too, but the truth is though that both the UD9 and Extreme6 runned roughly the same with the exception that the Extreme6 slightly out performed the UD9 in many of the tests.
Just one more point to add. The Asrock X58 Extreme6 1366 motherboard is a lot cheaper at around £181/$240 (as mentioned in the conclusion) where other high end motherboards are around £272 (like I paid for my UD7) or a lot more so not only does this motherboard out perform the UD9, but it is value for money too making this a much ideal motherboard to buy for those who are upgrading to 1366 from a lower socket. ^^
You can lol all you want, the Gigabytes are better built boards, and can support extreme voltages a lot better than ASRock boards can. UD7 and UD9 are both intended for people who push high voltages and max OCs, and hold up under those conditions. Start trying to run 1.7+Vcore on a Gulftown for long periods of time on the ASRock board, and see how well it holds up.
Do this with your ASRock board:

And that review is shit, considering I can get 190 BClock on my X58-UD5 with my 980X, which is using the older, less clockable version of the X58 chipset, not the better silicon of the X58A gigabyte boards. UD7 and UD9 both outclock my board.
That review site is crap. They just don't know how to clock for shit at that site. I browsed their other reviews, and all of their OCing results on everything they test is absolutely horrible. They only managed 151 BClock on a Rampage 3, ffs. They just suck at OCing. Don't know what else to tell you, tbh.
So, in closing, the ASRock is a spectacular, bang-for-buck deal, that can do some moderate overclocking. If you want a ton of features, good performance and plan to only air/mild water cool, by all means, grab the ASRock.
But it is in no way a better OCer's board than a UD7 or UD9, and isn't even really targeted at that market anyway, so the point is moot. I honestly don't know why they chose to compare it to the top tier overclock-oriented boards.
