System Benchmarks
Rightmark Audio Analyzer 6.2.5
In part due to reader requests, we are pleased to include Rightmark Audio Analyzer results in our benchmark suite. The premise behind Rightmark:AA is to test the input and output of the audio system to determine noise levels, range, harmonic distortion, stereo crosstalk and so forth. Rightmark:AA should indicate how well the sound system is built and isolated from electrical interference (either internally or externally). For this test we connect the Line Out to the Line In using a short six inch 3.5mm to 3.5mm high-quality jack, turn the OS speaker volume to 100%, and run the Rightmark default test suite at 192 kHz, 24-bit. The OS is tuned to 192 kHz/24-bit input and output, and the Line-In volume is adjusted until we have the best RMAA value in the mini-pretest. We look specifically at the Dynamic Range of the audio codec used on board, as well as the Total Harmonic Distortion + Noise.
As mentioned in the product overview and visual inspection, while the MSI uses the ALC1150, the traces from the audio codec and DACs have to travel some distance before getting to the gold plated audio jacks. Even though the analog signals in those traces should be separated from the other digital delivery on board, the distance is some 2-4 slots more than other products, resulting in a loss of quality.
USB Backup
For this benchmark, we run CrystalDiskMark to determine the ideal sequential read and write speeds for the USB port using our 240 GB OCZ Vertex3 SSD with a SATA 6 Gbps to USB 3.0 converter. Then we transfer a set size of files from the SSD to the USB drive using DiskBench, which monitors the time taken to transfer. The files transferred are a 1.52 GB set of 2867 files across 320 folders – 95% of these files are small typical website files, and the rest (90% of the size) are the videos used in the WinRAR test. In an update to pre-Z87 testing, we also run MaxCPU to load up one of the threads during the test which improves general performance up to 15% by causing all the internal pathways to run at full speed.
DPC Latency
Deferred Procedure Call latency is a way in which Windows handles interrupt servicing. In order to wait for a processor to acknowledge the request, the system will queue all interrupt requests by priority. Critical interrupts will be handled as soon as possible, whereas lesser priority requests, such as audio, will be further down the line. So if the audio device requires data, it will have to wait until the request is processed before the buffer is filled. If the device drivers of higher priority components in a system are poorly implemented, this can cause delays in request scheduling and process time, resulting in an empty audio buffer – this leads to characteristic audible pauses, pops and clicks. Having a bigger buffer and correctly implemented system drivers obviously helps in this regard. The DPC latency checker measures how much time is processing DPCs from driver invocation – the lower the value will result in better audio transfer at smaller buffer sizes. Results are measured in microseconds and taken as the peak latency while cycling through a series of short HD videos - under 500 microseconds usually gets the green light, but the lower the better.
Nothing new here – every Z87 motherboard we have tested so far seems to hit a peak DPC Latency of 150+. MSI sneak in under that, but only just.
WiFi Speeds
With the advent of 802.11ac now part of the motherboard space, it made sense to bring in hardware to test the wireless capabilities of the packages we review. Our test scenario is as follows – the router is located five meters away from the test bed and the signal has to travel through a concrete internal wall. The router is in a flat complex with over 25 access points within 50 meters, mostly on 2.4 GHz. We use a LAN Speed Test server on an i3-3225 based system connected via Ethernet to the D-Link 802.11ac router and then the LAN Speed Test client on the host machine. We set up a one hour continuous test using 10 simultaneous streams each sending then receiving 50 MB across the connection. Results are then plotted as a histogram of the data.
MSI’s bad decision to go with a 2.4 GHz WiFi solution results in a drastically poor WiFi result. In my testing scenario, there are numerous 2.4 GHz access points within range causing interference. 2.4 GHz, as a technology, is essentially dead for video streaming, especially in large cities. I feel MSI were wanting to tick the WiFi box rather than provide a solution, especially when motherboards almost half the XPower’s price come with 802.11ac 5 GHz.

You will. Most commonly they're 10 expansion slots high (the size of the first generation of extra large/tall mobos). Newegg carries 11 ten, 7 eleven, and 1 twelve slot tall cases vs 333 seven and 74 eight slot tall models.peterwhitehouse - Monday, August 12, 2013 - link
I think the form factor description is totally wrong surely it should be XL-ATX and not E-ATX?DanNeely - Monday, August 12, 2013 - link
That or HP-ATX; the other taller than normal board bucket. EATX is still 7 slots tall but somewhat wider to give room for two CPU sockets and ram banks in the top area.Nfarce - Monday, August 12, 2013 - link
Every time I see a Haswell tested and overclocked I cringe looking at the thermals. Even with an H70 this thing hits 85C at 4.7GHz. My 2500K stays at 4.8 on 1.39V at 60C in summer ambients on an ND-D14. Would like to upgrade to an i7 for video editing as well as a gaming, all-in-one system, but can't see that kind of heat happening. Maybe Ivy is the way to go for the last of the great overclocking chipsets?Death666Angel - Monday, August 12, 2013 - link
Have you listened to the Podcast #22 with Dustin Slavos? Anand and him discuss Haswell OCing very in depth, you should check it out.As it stands now, yes, you are thermally limited with Haswell. You currently get a little less OC headroom than with Ivy Bridge, but the IPC increase means you are still ~5% ahead in average work loads. When yields mature, you might see OC parity or even an increase, in which case Haswell will be about 10%+ better, sometimes more if the program takes advantage of the new features with Haswell. If you are to upgrade to a completely new system, get Haswell or Ivy-Bridge-E which should do better in the OCing department since it will likely use solder to connect the die and the IHS. I personally don't see the appeal to do an upgrade from one generation to the next these days, unless money isn't an issue.
But, 85°C is not an issue for the CPU. If the system isn't louder because of Haswell, anything under 90°C should be okay. And unless the two system were identical, you can't compare your 60°C to the 85°C, the cooler are different, you have different fans, different care fans and different positioning, difference socket placement..... :)

However, my summer temps - I live in the south of the US where it's hot nearly half the year - and my air conditioner bill would not like something cranking out 180F+ degrees. It's already hot enough in the room blowing 140F out the back with the Sandy rig combined with the 140F coming from GPUs. Bottom line - Haswell, while faster clock for clock than the Ivy which itself is faster clock for clock than Sandy, is not the "next level" I was hoping for. Finally, as stated, the only reason I'm looking to upgrade to i7 from i5 is to speed up my video editing and rendering time, which I'm doing more and more of these days.

Nfarce, it doesn't matter if you put 90W of heat into your apartment at 180F or at just 90F, your room temperature increases the same amount! In fact, those massive coolers actually draw so much more power that you'll actually increase temperatures. Don't spout nonsense like that, it's beyond ridiculous. If you care for cooler temperatures, go for the system that uses the fewest Watt average (including idle time), and that system will surely not include this mobo!ggathagan - Monday, August 12, 2013 - link
"$440 is a big ask from MSI, which is placated some by the inclusion of a mouse mat and goodies in the box.""Two thumbs up from MSI on the self-branded additions to the box."
Seriously Ian?!
$440 should buy me an amazingly solid board that will do what its manufacturer claims it will.
Anything less is unacceptable and simply encourages board makers to continue this trend of cranking out their top tier products before they are actually ready for everyday use.
Spare me the marketing material, the out-dated 2.4GhZ wireless the useless 'Killer' NIC and spend your time/money on producing a satisfactory motherboard!

Dumb ass spammer..If she only makes $62 an hr, yet brought in $20,900 in a month..that "few hours" she worked totals 337 hours..If you are going to waste your time typing spam messages that everyone here is smart enough not to follow, then you *SHOULD* be smart enough to use a friggin' calculator Bahahah...On topic, ggathagan you are exactly right! $3 worth of useless marketing fluff doesn't really make you want run out and buy this board over others that are half price but perform just as well..For $440, this thing should come with a full set of custom waterblocks for the VRMs/chipset, and ship with a stable BIOS for God's sake! I really liked the platform offerings of Z87 on paper, but I am glad I held onto my 3770k @ 4.8Ghz..
Every Z87 board seems to have their own slew of issues, from BIOS issues to XMP issues etc etc..My $115 ASRock Z77 Extreme4 has been rock solid from June 1st of 2012..It runs 24/7 @ 100% load (F@H), and is the BEST MB I have ever owned under $150..
I used to buy nothing but higher end boards ($200-250), and am super glad I took a chance on this "mainstream" performance board! I sure hope Ivy-E brings some updated X79 boards (native USB 3, more SATA 6 ports, better Audio) so I have something to be excited about!

If u going to 4 way crossfire / sli or even 3 way, then where u put your sas card or any other pci xpress card? cause theres no pci xpress slot left available. This kinda boards is all about having multiple gpu but still got everything else.
