LAN Speed Test
LAN Speed Test is a freeware program designed for testing the network connection between two PCs on a home network. The speed of the transfer is limited by the lowest common denominator on the network, so if you have gigabit Ethernet capable computers but a 100 Mbit capable router, you are limit to 100 Mbit transfer. Note that this is really a formality – if a network port is rated at 1 Gbps, then chances are that it will hit at least 90+% of this value. The main test here is CPU usage, and how much is offloaded by the controller. For this test, we use LAN Speed Test to transfer a 1000 MB file across a home network with a 100 Mbps lowest common speed to the same machine each time, in a read/write scenario. CPU usage is taken as a visual max/average from task manager.
Good to see the Realtek controller doing its job properly here - the board is certainly a very strong contestant in the networking department.
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.
The Gigabyte performs very well - 120us is lower than almost all the other motherboards.
USB Speed
For this benchmark, we run CrystalDiskMark to determine the ideal sequential read and write speeds for the USB port using our 64GB Patriot SuperSpeed USB 3.0 drive. Then we transfer a set size of files from the SSD to the USB drive, and monitor 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 Sorenson Squeeze test.
The USB2.0 speeds are more or less all the same. However, this board really shines when it comes to the write speeds. It’s on average 5MB/s faster than most of our boards we’ve tested and is only really contested by ASRocks’ XFast technology. The copy time is fairly average. On the USB3.0 side of things, the results are not anything spectacular.
SATA Testing
We also use CrystalDiskMark for SATA port testing. The operating system is installed on the SSD, and the sequential test is run at the 5 x 1000 MB level. This test probes the efficiency of the data delivery system between the chipset and the drive, or in the case of additional SATA ports provided by a third party controller, the efficiency between the controller, the chipset and the drive.

Use of plurals for a single entity derives from not knowing which part of that entity the speaker is talking about. It is very curious. I may be wrong but I cannot remember, "IBM have", "Apple have", "Asus have". They are all upstanding members of their trade and craft. But, while Gigabyte is good enough, there is something about it that prevents people from looking at it as a solid entity that deserves a singular reference. In fact, I would go as far as saying that the message is that the unpredictable collection known as Gigabyte has given us this, this time at this price. Gigabyte could as well have priced it $420. As if the pipeline is just cut off at random by a random part of that collection and a product shipped to the market. Not the case with Asus or IBM. Hence, IBM "has", Asus "has".Of course, with regards to the British the plural is a sign of respect. Remember, they are a monarchy, with hereditary parliament membership, and apparently very happy and proud of it. It is absurd to refer to a member of the house of lords in singular terms. Each is a well known clan. Oh, and well respected!!

I'm glad someone brought this up. Anandtech editors should edit articles to be consistent.The problem is that American English has a different rule than European English. The American English rule is the correct one. A well-edited scientific site like ArsTechnica recognizes this and edits all of its articles (notice that I used the singular possessive pronoun "its" there) to that end. Anand himself does a nice job with this since he's an American.
Some of the other American writers are being influenced by Wikipedia, British writers, and other sources of confusion. The fact is that number must agree throughout the entire sentence. Logically, the British rule can never accomplish this harmony of number because the corporate entity is always singular. Writers can easily avoid ambiguous constructs by making the subject more specific which helps convey meaning, eg., "Apple's engineers have" or "nVidia's marketing gurus are," etc.

Grammar can be an observance of and more than, rules. Style may be approached. Cautiously."I'm glad someone brought this up. Anandtech editors should edit articles to be consistent."

English writers have and are not considered a source of confusion with the English language any more than writers of other nationality's, Americans included.
Corporations and other entities can be personified perfectly well.
'Apple has pursued it's singular goal' is acceptable as the intention of one entity, further distinctions are made with relevant reference.
'Jobs has a plan for apple"

'The right honorable' is considered the appropriate honorific (they rarely are), it is singular and they, depending on who you ask, are sometimes respected.
British English is adequate until you reach then end of it, then you can use American English if you must. ;)

Byr,I have literally no idea what you were trying to say there. Reading your post made me feel like I had been drugged.

"The problem is that American English has a different rule than European English. The American English rule is the correct one. "Look buddy, American English is not correct. Americans cannot spell and if, like me, you have ever had to read a document drafted by an American lawyer, punctuation is not an American strong point but verbal diarrhoea is.
I would say that the only correct form of English is what you call British English, but fact is that English is very flexible. As long as Anandtech are consistent that is fine.
Anyway back to the board. Fan control. Do Gigabyte own shares in one of those companies who make separate fan controller? Because that is the only excuse for such a pitiful on board control

It's funny how you can determine with such certainty that one rule is correct and another is not. Language is not based in math, it is an arbitrary set of rules driven by speaker inertia. If both variants of the rule set are equivalent in functionality, neither can be considered correct or even superior. In "Gigabyte has/have released a new motherboard", "Gigabyte" could mean either "the Gigabyte corporation" or "the people at Gigabyte". I could argue that the singular variant is illogical because a corporation, an abstract entity, cannot perform any action other than perhaps come into existence. Or I could argue that the plural variant is wrong because fewer people use it. This, of course, would be pointless.marc1000 - Monday, July 11, 2011 - link
nice board, but without speed control on the sys fans, it is less interesting than other options... also very few sata ports for a new product. Gyigabyte is really keeping it "safe and cheap".EnzoFX - Monday, July 11, 2011 - link
One of the great things about UEFI is the faster boot times. Does this hybrid BIOS allow the same? If it's merely a question of cosmetics, then the classic BIOS look would not bother me.paul878 - Monday, July 11, 2011 - link
How was the cpu temperature measured?cyberguyz - Monday, July 11, 2011 - link
... and most motherboard manufacturers are guilty of this, is the fact that they stick the PCIe-1x slots directly below the PCIe-16x slot and leave the outdated PCI slots wide open down at the bottom of the board. It really burns me that these guys don't think of the fact that most new add-in cards are being produced to use in the more modern PCIe-1x and PCIe-4x slots. An example is that I have a PCIe sound card, a high speed network card and a raid controller. Because I also have an Asus GTX 570 Cu II video card (eats 3 slots), I can't use any more than two of these (If I don't mind losing 8x lanes to by x16 card and don't mind snuggling up the shortest one of these PCIe cards really close to the backside of that really HOT video card). Yet I have 2 ncie cool PCI slots sitting out there in the open airstream with no hot components anywhere near them. Video cards are challenging enough to cool without crowding cards within a couple millimeters of them.In order to use all my PCI devices I have to find one of the very few and more expensive motherboards that provide nothing but PCIe slots (No PCI bridge = more expensive - where is the logic in that?)
Grrrr! I have no gripe in mobo makers including a couple PCI slots. There are users out there that will still use them for a few years to come yet. They just need to think that as we progress in technology that these older slots are being abandoned by users in favor of the more modern PCIe versions of their add in cards.
