System Benchmarks
Rightmark Audio Analyzer 6.2.5
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 discussed the complexity of RMAA testing in a previous news post, but here we look specifically at the Dynamic Range of the audio codec used on board, as well as the Total Harmonic Distortion + Noise.
RMAA Dynamic Range of MSI X79A-GD45 Plus
The MSI mimics other ALC892 motherboards such that the audio performance, particularly in dynamic range, is on the bottom of our scale.
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.
With our newer USB testing methodolgy, the MSI has the first NEC USB 3.0 we have seen and tested. The poor results speak for themselves.
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 - less than 500 microseconds usually gets the green light, but the lower the better.

In Board Features > Memory Slots, says "Up to Dual Channel". Shouldn't it be quad channel?dgingeri - Friday, February 14, 2014 - link
Well, it could be useful for a high level home server with that many slots. Put a low end video card in the top, raid controller in the second, quad port 1Gb NICs in the 4th and 5th, and have the last slot available for a 10Gb card if needed. Wouldn't even need a switch to go with it. All in one, storage, network, routing, high end network. It has possibilities.Rick83 - Friday, February 14, 2014 - link
But most of that you can do with 1155, and for that price you can get a board with ECC support to boot, won't need any GPU at all (unless you get a Xeon that has the GPU disabled), and still have plenty room to grow. 1155 has plenty of PCIe bandwidth, as long as most of your load is from two expansion slots. Hooking up RAID and networking directly to the CPU means that you will have two or three expansion cards that may eventually be bandwidth restrained, but even then opting for a board with a PCIe MUX would be in the same league, price-wise as this, and have plenty of bandwidth for up to four cards - and most non-GPU cards aren't really PCIe restricted. Quad GbE is one lane PCIe3, 10GbE is 2-4 lanes, 8x 6Gb SAS with software RAID over SSDs is going to need 8x PCIeV3, but realistically 4x is going to be enough, if you use hardware RAID or spinning platters.No, the only reason for this board, is if you want a cheap rendering machine. 6-8 cores and 64GB of RAM on a 250 dollar board is pretty nice. If you want gaming, you'll probably be looking at boards higher up the foodchain, as the GPUs alone will come in at around 2-3k dollars, and another 100 on the board won't really matter, if you get better sound and other nifty features.
GPU computer might be another use case, but then that's even rarer than rendering boxes, from what I've seen so far. Might be a nice little GPU compute dev workstation.

There really isn't any need for this as a home server. It's total overkill. Even a Core 2 Quad can transcode multiple 1080p streams while serving files, routing and doing all the other common home server tasks. Home servers don't really need much power, most homes don't have more than 4-6 users.dgingeri - Friday, February 14, 2014 - link
For total I/O and a poor man's 10Gbe switch, socket 2011 or 1366 can't be beat. That's what I mostly use my home servers for. Socket 775, 1155, or 1150 systems simply can't provide the I/O to run a software switch that includes 10Gbe.Yeah, sure, 10Gbe is hardly worth the expense in a home server. However, with a raid controller and quad drive set capable of pushing 400MB/s, it can be useful for video editing over a network drive, or a few other things.
I do it as an experiment on future uses and self training. Right now, I have three servers interconnected with 10Gb over such a poor man's 10Gbe switch running a total of 14 VMs over 3 domains with 6 domain controllers, 3 WDS servers, and some 'workstations', just to prove I could do it before I propose doing the same thing with the DNS servers in my lab. (We currently have 4 domains across 17 departments, with 3 of those 4 running Linux DNS servers that don't talk to each other. It's really annoying working on machines that cross those domains. So, I had to come up with a plan to fix it with Windows DNS and AD, and eventually migrate down to one domain. In addition, I was to come up with a way to manage user accounts through Windows AD for a single centralized vCenter server to manage our test VM hosts. I wasn't sure I could do it until I spent a weekend building all these VMs.) All of those VMs are running on iSCSI storage over 10Gbe from the storage server. I did all this with two Dell T110 II servers, one for storage and one for routing/switch, and a piecemeal FX-6100 VM host and 4 Intel CX4 10Gbe NICs.
In essence, I was just dreaming about a more capable central server for my experiments when I posted that previous comment. I could switch the storage and switch duties to a system with this board and use the Dells as further VM hosts. Maybe I'm just spoiled with all this hardware at work.

Copy/Paste error from my spec tables which I hand code to make it easier :) Should be fixed.Ian

Ok I am not one to criticize articles, but this reads REALLY poorly. I mean I am the guy who misspells every other word and uses slang, misses apostrophes etc. So I forgive everything as long as its readable. But I could not get past the first page of this review.The writer misuses "are" and "is" so often I have to reread every other sentence. He completely misses using the word "the" and it also makes you reread each sentence. Read the first two paragraphs and someone tell me I am wrong? Am I just grumpy, hungover or what?

Hahaha, you must be new to Ian. He's rather infamous for his "style."It would seem that eloquence is not as valued as passion when it comes to the tech journalism industry, even for Anandtech. Refer to the 14 AIO coolers article and its comments section to see an excellent example of what I mean. There I had a little exchange with the author and boy, it’s not pretty.
Although one could say that one doesn’t read a motherboard review, or any other tech article, to brush up on one’s English grammar or writing skills, but rather just to look at some pretty pictures, learn the price/specs, and read the conclusion, it’s somewhat of a weak cop-out as one would also expect AnandTech to strive for higher standards. Reading is reading and a poorly written article is a poorly written article, regardless of topic. Other sites aren’t much better though. And to their defense, there are some decent writers, in terms of pure writing, here at AnandTech, not least of which is Anand himself. And who knows? I might even answer AnandTech’s Call for Writers one of these days. So fret not, all hope is not lost.

I would absolutely loathe you writing for this site. I'm sure the other writers would hate you writing with them as well, pretty much every time I see you in the comments it is because you are complaining of the competence of the english and grammar of the article.BlakKW - Saturday, February 15, 2014 - link
