ASUS X99-A In The Box
So far from our X99 motherboard bundles it has been rather reassuring that for the high initial cost of the parts that the manufacturers are willing to bundle enough to focus on gaming and storage. The ASUS X99-Deluxe did this with a couple of M.2 additions, a protective cover for the left hand side of the board and a bundled fan extension PCB. However the inclusions in the box from ASUS in the X99-A might come across as pricing down to a point. We get the following:
Driver CD
User Manuals
Rear Panel
Four SATA Cables
Q-Connectors
Flexi SLI Bridge
Despite there being a focus on three-way GPU configurations, only one SLI bridge is provided. Having the right size for three-way would be a help here. Four SATA cables is two fewer than almost all other X99 boards as well - this should satisfy most users trying to use X99 on the cheap.
Many thanks to...

ASUS X99-A Overclocking
Experience with ASUS X99-A
ASUS' overclocking options derive mostly from the AI Suite 3 software as part of the 5-Way Optimization tool. The software will find an overclock with appropriate stress tests for an automatic setting, or the user can manipulate the TPU or Turbo App software manually. For automatic overclocking a user can also adjust the TPU DIP switch on the motherboard itself. This switch gives 39x100 and 31x125 for setting one and two respectively. Manual overclocking is best performed through the BIOS which offers ASUS' usual extensive array of options.
Methodology
Our standard overclocking methodology is as follows. We select the automatic overclock options and test for stability with PovRay and OCCT to simulate high-end workloads. These stability tests aim to catch any immediate causes for memory or CPU errors.
For manual overclocks, based on the information gathered from previous testing, starts off at a nominal voltage and CPU multiplier, and the multiplier is increased until the stability tests are failed. The CPU voltage is increased gradually until the stability tests are passed, and the process repeated until the motherboard reduces the multiplier automatically (due to safety protocol) or the CPU temperature reaches a stupidly high level (100ºC+). Our test bed is not in a case, which should push overclocks higher with fresher (cooler) air.

No. Look at the pictures; 6 blue (3.0) and 4 black (2.0) USB ports.Until Intel goes all USB3 on it chipset, most boards with many ports are either going to do a mix of both types, fake it with hub chips, or both. And since the Skylake Leaks indicate we'll probably still be mixed USB (or hub) on higher end boards (midrange will probably be able to go all 3.0); it's probably going to be 2017 until USB3.x becomes ubiquitous.

You said this board doesn't implement Multicore Turbo but its specs does says Intel Turbo boost supported. Could you elaborate more on this.Does this means it will get turbo boosted for single core only? 8 cores active can not get turbo boosted?
SuperVeloce - Wednesday, December 24, 2014 - link
This most likely means turbo boost is behaving as Intel said it should, more cores active, lower the frequency (for 5960x and all cores its usually 3-3.2ghz). Multicore turbo usually gets you highest turbo frequency for all cores (so it would leave it 3.5ghz@16threads if temperatures allow it).dcoca - Friday, January 9, 2015 - link
I have this board and Multicore is there in the bios with the opt for all cores or per core...EricCC - Wednesday, December 24, 2014 - link
Great article. I was ready to buy one until I saw the post times. 20+ seconds is horrible. My two year old Surface and one year laptop with Haswell post in 2-3 seconds and their CPUs are much slower. And my 5+ year old system is twice as fast posting.I thought EFI BIOS were supposed to be significantly faster and I expected newer machines to be faster. Have manufacturers explained the severe slowness?
Are these new motherboards any faster with Windows 8?
EricCC - Wednesday, December 24, 2014 - link
i should have said, any faster POSTING with Windows 8?DanNeely - Wednesday, December 24, 2014 - link
POST is the time spend *before* the boot loader starts your OS. In general, the more stuff that needs to be started up, the longer it will take to POST; however, I suspect that an additional factor vs Z97 boards which post in half the time is that more effort has been put into optimizing performance for the mass market product than for something that's mostly used in servers/etc where it's a much less important factor.EricCC - Thursday, December 25, 2014 - link
I am aware that POST time is pre-OS, and all the times I stated are POST only. The OS loads in around 10 seconds so most of my systems boot faster than the X99 motherboards POST. Do you think these boards would POST faster with Windows 8? I thought systems that were Windows 8 aware were able to skip part of POST or at least do something differently.I also agree that POST and boot times in servers tends not to be that important but I don't think these boards are for servers, which don't need the ability to run with multiple graphics cards or to overclock.
Do you not think that 20+ second POST times are extremely long for computers nowadays?
DanNeely - Thursday, December 25, 2014 - link
No. Your OS has nothing, and can have nothing, to do with POST time because your OS doesn't get involved until the POST is complete. It doesn't matter if you're running Windows 8. or Windows 7, or Windows 3.11, or Linux, or BSD, or BeOS.What Win8 does is to only partially shutdown by default when you turn it off. It closes down everything in userspace and then hibernates the kernel. Then when you power on, after the computer POSTs, and after the boot loader starts win8, win8 just unhibernates the kernel and restarts userland; which is faster than starting the OS from scratch. This also only helps if you're someone who turns his computer off on a regular basis instead of just leaving it up until the next patch tuesday; because in that case the patches require restarting the kernel.
These boards aren't going into servers; but 99% of consumer boards are LGA1150; which is where the OEMs put their effort. LGA2011 is an entry level server product; and 99% of the chipsets for them go into servers where it doesn't matter.
X99 is too small a market to justify any sort of performance tuning; the boards are already a lot more expensive than z97 because the tiny number of boards that are sold means there's not much to spread the engineering costs for the board layout over. If you wanted to lift the base price of the boards another $100+ each it might be possible to optimize the startup times down to the same 10s ballpark of z97. You'll probably never see desktop boards get down to the 1-3s range of thin laptops/tablets because the latter have so much less stuff to enable, and everything that they need to turn on and since everything is soldiered and non-replacable they can encode all the settings into the firmware instead of having to detect the components and determine how to configure them every time they're powered on.

The X99-A BIOS is full of options that allow faster POST (like not looking for other drives than the boot drive etc). So it can probably be tweaked.
