POST Time

Different motherboards have different POST sequences before an operating system is initialized.  A lot of this is dependent on the board itself, and POST boot time is determined by the controllers on board (and the sequence of how those extras are organized).  As part of our testing, we are now going to look at the POST Boot Time - this is the time from pressing the ON button on the computer to when Windows starts loading. (We discount Windows loading as it is highly variable given Windows specific features.)  These results are subject to human error, so please allow +/- 1 second in these results.

POST (Power-On Self-Test) Time

I am not sure exactly what ASUS has done with the Premium, but the boot times are excellent compared to other Z77 motherboards.  Only a single ASRock motherboard we have tested gives better boot times at default.

Update: It turns out ASUS has moved from a legacy ROM format to a CAP format in their BIOS system - this allows for quicker booting.  This is being rolled out on their X79 and Z77 range as we speak, and should be ready for Windows 8 as well.

Overclock Comparison

Here at AnandTech we want to provide quick and easy ways to determine if a board is good for you (with in-depth analysis of course).  So here is a quick round up of our overclocking results.  Overclocks are tested for stability with PovRay and OCCT - while these may not be the most strenuous of stability tests, it does offer a quick check for memory errors under high load (and also balances testing time with getting the next board on for review!).

    I'd say that in the next five years I'll buy... 0 Thunderbolt peripherals. Heck I've only just been bothered to buy my first USB3 thumb drive. Others, however, will jump all over it to be special or actually have a 'genuine' use. Reply

    Stopped reading at "$450," but it was interesting to learn that a person could spend that much on a PC motherboard. Reply

    So to nit pit, but I the noun Asus is singular. "ASUS have gone for the additional extras" should be ASUS has gone for the additional extras. Reply

    Re-read your first sentence, and tell us if it makes any sense. Then consider again if you should be one to give people grammar lessons.

    "ASUS" is a corporation name, corporations are groups of people, that means "ASUS" is a collective noun, so plural verbs can be used with it just fine.

    This is a US vs. UK thing. Here in the UK, collective nouns are plural.

    In the UK and most of the Commonwealth, "ASUS have" would be the correct usage. Reply

    I am disappointed in the lack of PS/2 support which does have it's advantages over USB. Especially for us Vintage Keyboard Lovers. Reply
  • Googer - Monday, August 13, 2012 - link

    There is room on the back of that I/O panel for PS/2. I've used USB keyboard adapters and its not the same as native PS/2 support. If having PS/2 on a motherboard bothers you, then don't use it and it will likely disable it's self in P.O.S.T. Reply

    for $450 I would expect that it would at least match my sabertooth x58 @ 5 years.

    I like that it does have dual band wifi/bluetooth but I don't think I will ever spend that kind of cash on a board

    One comment about the temperature measurements, as it keeps being mentioned about the varying ambient conditions. Could you not change to a delta reading? So as to remove ambient from the issue? Obviously extreme variations in ambient should still be mentioned.

    Bit-Tech.net do this on their reviews and it seems to make a lot of sense.
